Introduction

General DescriptionThe D-Determinator is part of a modular system solution for the dosing of cleaning products into cleaning application (i.e.CIP, bottlewashers or other cleaning process). It offers a high level of flexibility: The D-Determinator can operate by itself ornetworked for a multi-zone application.

• The concentration of cleaning solution can be controlled via a fixed volume of product per time or by measuringthe conductivity, pH or the RedOx potential and controlling to a desired setpoint.

• Up to two additional products can be added either as fixed volume per time or proportional to the volume of themain product.

• A separate and typically larger initial charge pump can be configured to add the main product faster.

• Up to four D-Determinators can be networked together, via CAN-Bus, using the same equipment controllingcleaning solution being distributed to multiple dosing points.

The process equipment that can be monitored and controlled by a D-Determinator unit is shown below. Not all of theequipment shown below is required for every dosing application. To improve material tracking functionality additional flowtransmitters can be added to monitor consumption. Low level sensors can be added to check the level of product in the supplytanks or drums.

All these process signals can be connected to the D-Determinator, but the only equipment that is required are the dosingpumps.

The D-Determinator system is comprised of a wall mountable control unit with a separate access area for the field connections.The control panel has 4 keys and a LCD display with 2 rows by 16 characters per row. All activities of the dosing system arecontrolled and monitored from the LCD display and the attached external devices. The control system is configured using thecommands and input screens on the LCD display.

The D-Determinator has four electronic AC relay outputs for controlling four pieces of dosing equipment (dosing pumps orvalves). For each dosing item, there is one ‘power’ digital output driving the pump or, in "Slave"-Mode the valves. Fouradditional relay outputs control the stroke pulses if stroked dosing pumps are used. TheD-Determinator’s dosing operations can be activated and inhibited from an external device through the trigger release input."Initial Charge" and "Start-Up" dosing can also be started by an external device through separate trigger inputs. Optionally,the D-Determinator system can be networked to a computer running configuration and monitoring software that operatesthrough the CAN-Bus interface.

More than one D-Determinator may be connected together using the same process equipment to control different stages of amachine. In this case one D-Determinator is "Master" and controls all dosing equipment and one part of the machine. Theother D-Determinator (s) act as slaves and control valves from the transport line to "their" part of the machine.

When a system with a single D-Determinator is running in Automatic Mode, the D-Determinator controls the dosingequipment per the configuration enter into the controller. A system composed of more than one D-Determinator running inAutomatic Mode requires a CAN-Bus -Interfaces. The D-Determinator configured as the “Master“ controls the dosingequipment and all "Slave" nodes make request for product to the “Master” and wait for a response.

Optionally, the D-Determinator system can be networked to a computer running configuration and monitoring software that operates through the CAN-Bus interface.


The possible operation modes for a D-Determinator are as follows:

No Release : No dosing activity possibleAutomatic : Dosing automaticallyInitial Charge : Dosing an initial chargeStart-Up : Dosing a start-up chargeManual : Dosing a manually set charge of product

D-Determinator Control Features

• Controls dosing equipment for one main product and up to two supplementary products in Automatic or ManualMode.

• Monitors daily and total consumption for each cleaning product via a pulse flowmeter or by counting the time thedosing pump is running. The pulse flowmeter option provides a more accurate consumption amount, but it requiresadditional process equipment.

• Triggers alarm messages and halts current processing step when process alarms occur.

• Systems can be networked through an optional CAN-Bus interface.

• The configuration menus are password protection.

• Several different operating modes for controlling the dosing pumps.

• Several different operating modes for controlling the cleaning solution’s concentration.

• An additional high capacity pump can be connected to reduce the time required to complete an initial charge orstartup charge.

This document is describing version 1.21 of the D-Determinator hardware and software.


Hardware Setup

Notes on SafetyTo ensure that the controller functions perfectly and has a long, useful life, the user must observe the instructions in thismanual and must proceed according to the conditions of use. Commissioning and maintenance personnel must have beentrained and authorized to carry out such activities. Appropriate measures must be taken to prevent unintended actuation andcausing detrimental influences on the process. The applicable prevention and safety regulations for electrical devices must beobserved during operation, maintenance and repair of the controller.

A qualified electrician must make all electrical connections. Always disconnect from power supply before opening the cover.Warning: Danger of electrical shock inside.

Electrical components should not be exposed to water or moisture. If this occurs by accident, a qualified electrician mustservice the unit.

A qualified electrician following all the local and country electrical codes should install the D-Determinator.

Mounting and locationThe D-Determinator unit should be mounted on a clean, vertical surface and kept away from heat (<50°C), moisture andvibrations. As shown in the mounting diagram (Appendix E), there are six mounting holes to mount the D-Determinator unitto a wall - three on each side on the back wall of the plastic box. When you have located the place for the control unit, mountthe box securely in place.

See flow sensors manual for proper mounting of the desired flow sensor.

See conductivity sensors manual for proper mounting of the desired conductivity sensor.

If other sensors are used such as pH or RedOx verify they are installed properly by checking their installations manuals.

Wiring notesFor the electrical wiring of the components, pay attention to the maximum cable lengths between the D-Determinator unit andthe other components (refer to the technical manuals of the components). Connect wiring as shown in wiring diagram(Appendix B).

Power WiringMake sure the power is OFF which connecting it to the D-Determinator. Verify the power jumper is in the proper location(115VAC or 230VAC) before connecting power to the D-Determinator. Make sure that all attached equipment is inconformance with the electrical specifications (Appendix A).

Analog InputsAnalog Sensor: There are two analog input channels available on the D-Determinator. They can be configured forconductivity (typically), RedOx, ClO2, temperature, pH or direct.

Flow Sensor: The three pulse flow sensors channels. These flow sensors are optional equipment and can be disabled duringconfiguration if not connected. In this case no direct measurement of product consumption is possible; the product flow willbe calculated from the characteristics of the dosing pump. The product consumption’s will also be calculated from the pumpcharacteristics.

Digital Inputs


These digital inputs are potential free digital input signals. All input clamps also feature 0 volt and 24 volt access.

Low Level Switches: Connect level switches for the empty level. An ‘OFF’ signal (open contact) refers to an empty tank; a‘ON' signal (closed contact) refers to a tank that is not empty. A broken wire or a faulty connection will also prompt an alarm.If this contact is opened while product is running, an immediate alarm will be produced and the dosing pump will be stopped.If there isn’t and actual low level switch in the product drum then these channels need to have a manual jumper install acrossthe contact to allow the dosing pump to run. If this jumper is install there is a good possibility that the pump will run when thechemical drum is empty. This may cause damage to the dosing pump. It is recommended that a low level switch be installedon the pickup lance of the chemical and wired to these inputs for safety.

Release Trigger. The Release Trigger can be connected to a switch or to an external device, for remote triggering of thesystem. The system will run in automatic mode when the external contact is closed.

Initial Charge/ Start-Up. These inputs can be connected to a switch or to an external device, for remote the starting of aninitial charge (or start-up) dosing. The system will start when the external contact is closed.

Machine Counter. This input is used to dosing product based on an external signal that represents machine activity. Such asa rack counter for a bottlewasher or a keg counter for a keg washer. The cleaning product will be dosed proportional to therate the machine is running per this signal.

Digital Outputs

Connect the 4 dosing pumps to the respective output ports. If you are using a stroke pump, connect the pump also to thecorresponding Stroke output port. The Stroke outputs are the optical relays that are labeled SxC and SxE, where x is thedosing pump number 1 to 4. These channels have a maximum voltage of 24 volts DC. There are also control relays that thedosing pumps can be wired to that can handle higher voltages. These control relays are labeled PxA and PxB where x is thedosing pump number 1 to 4. The PxA relay contacts are for 24 volts DC and the PxB relay contacts are for supply voltage(either 115VAC or 230 VAC). See the wiring sketches below for more details.

The D-Determinator system provides two other relay outputs to notify the operator when the system is in alarm and the systemis running. The alarm output can be used to trigger an external device, such as a lamp or a horn. The running output signifiesnormal operation, and can be attached to an external device, also.

For the maximum output ratings, see the Specifications sheet (Appendix B)

System Configuration

GeneralThe D-Determinator system can automatically control the chemical concentration of the cleaning solution by feeding the necessaryproduct into the machinery. To accomplish this, the D-Determinator monitors 2 analog sensors and controls up to 4 pumps orvalves.

Sensors: Sensor 1: measures the cleaning solution’s conductivity, pH, RedOx, ClO2 ordirectly measures any analog transmitter (current loop)

Sensor 2: measures temperature for compensation of sensor 1, simply measuretemperature or a second RedOx sensor can be connected.

Pumps: Equipment 1: doses main product

Equipment 2: doses additional product 1

Equipment 3: doses additional product 2

Equipment 4: pumps main product during Initial Charge or Startup

Equipment 1 can be configured to perform a time constant dosing ("Volume Fix") or to control the concentration of cleaningsolution to an analog setpoint (“Analog Regulatory”). To pump the higher amount of the main product during an initial chargeoperation a larger pump can be installed and connected to Equipment 4. This pump will only be used during Initial Charge andStart-Up operations. While the system is running in Automatic Mode, dosing will be performed automatically until the TriggerRelease input is OFF (“open contact”) requesting the D-Determinator to stop automatic control.

Equipment 2 and 3 can be configured to deliver product on a time constant dosing ("Volume Fix") or to control to a ratio of themain product dosed, this mode is call Dependant. In dependant mode the amount of product 2 and 3 that will be dosed is based onthe ratio of the consumption amounts, main product to product 2 and/or product 3. The product may or may not be dosed at thesame time depending on the minimum feed amounts for products 2 and 3.

When a process alarm (i.e. low level in product drum) is generated the dosing pumps are stopped. There are several alarms thatwill cause the dosing to stop and there are others that are only warnings, they are listed in Appendix G.

The configuration menus and consumption resets are password protected, so only authorized individuals can perform these tasks.When inappropriate values are entered in the Configuration Menu, or a setting is not possible, the D-Determinator system willinform the user.

While the system is being configured, the D-Determinator system will not perform any dosing - all of the system outputs areblocked and the field signals are set OFF (open contact). When the Configuration Menu is exited, the system is immediately readyto perform the desired dosing operation.


System Flow Charts and Control Panel KeysThe four system flow charts - Operation Menu and Configuration Menu (includes two Submenus) (see Appendix C) - are the roadmaps that will guide anyone through the D-Determinator operations and configurations screens. Whether you want to configurethe system to run automatically, activate a manual dosing, or view product consumption totals, the flow charts will show you thepath you must take to accomplish your task.

The D-Determinator system commands, which appear on the LCD display and rotate in a looping fashion. Depending on whichkey you press on the control panel in different operator screens will be displayed depending on which area of the D-Determinatorthe operator is working.

The two control panel keys, Select and Enter, are indicated on the flow charts by ‘S’ and ‘E’, respectively. These keys generallyrepresent the two different options which are available from any given display screen in the D-Determinator Control system. Withthe Enter key, you can also generally proceed through the system and view system settings, without changing the data.

SELECT SELECT: moves to the next menu item but does not start function.

ENTER ENTER: confirms last entry and continues.

The two arrow keys on the control panel are generally used to make configuration selections and set numeric entries:

ò Down arrow: decreases number in digit field ortoggles between ‘Y’ and ‘N’ in Yes / No field,(field values are pre-set with zero entries).

ð Horizontal arrow: moves cursor to the next digit field,(or pre-sets fields with preceding entries).


Entering Configuration ModeWhen the control unit is turned on for the first time, the start-up screen will read:

Configuration Enter

As shown on the Operation Menu flow chart (bottom left corner), press the Enter key to confirm, and begin Configuration.

Enter Passwordxxxx

The system requires that you enter a password in order to have access to configuration capabilities. Enter the four-digit password,using the down arrow key and the horizontal arrow key. Press the Enter key when the password is completed and the D-Determinator will display the Configuration Menu – for quick references see the Configuration Menu flow chart in Appendix A.

The general setup of the control system will now be configured, product consumption totals can be read and reset here, thepassword may be changed and the inputs and outputs can be tested.

Referring to the Configuration Menu flow chart (Appendix A), use the keys on the control panel to respond to the information onthe LCD display (see System Flow Charts and Control Panel Keys).

H3PO4 : The concentration of H3PO4 (Phosphorous acid) is displayed. The measured conductivity istransformed into a concentration value via a stored calculation diagram. The maximum scale has to beset also

H2SO4 : The concentration of H2SO4 (Sulfuric acid) is displayed. The measured conductivity is transformedinto a concentration value via a stored calculation diagram. The maximum scale has to be set also

HNO3 : The concentration of HNO3 (Salpetric acid) is displayed. The measured conductivity is transformedinto a concentration value via a stored calculation diagram. The maximum scale has to be set also

curve : A free concentration is displayed. The measured conductivity is transformed into a concentration valuevia a stored calculation diagram; this diagram is set by the user ("Free Cond. Curve", see below).

Cond. Scale max.1: 2000 mS

The maximum scale of the sensor (analog input 1) is set in a range from 1 to 2000 of the units selected above. This is thedisplayed value when the process sensor is reading full scale or a 20mA current value.


Below are the two screens that the operator can use to enter a free conductivity curve. Relating conductivity to concentrationpercent.

Free Cond. Curve1-1:0500mS=0,00%

Free Cond. Curve1-1:0500mS=0,75%

If the conductivity has to be displayed in terms of a user specified concentration characteristic, data can be entered. For up to 8points of a characteristic (called 1-1...1-8) the conductivity in µS / mS and the corresponding concentration. The characteristiccurve will start with the data enter in to the 1-1 parameter and end with the data entered in the 1-8. When the conductivity valuehas been entered, hit the ENTER key to enter the corresponding concentration. When the concentration value has been enteredpress the ENTER key to advance to the next point on the curve.The relationship between concentration and conductivity has to be a uniformly rising function. Therefor the default values for thefirst point is "0 µS / mS" and "0%". Setting the following points the minimum values for both concentration and conductivity willbe the corresponding value of the previous point. The default values for these points are the values of the previous point. That is,if an additional data point for a characteristic has to be entered, some points will have to be shifted.

It is possible to see all the data points by pressing ENTER multiple times.

Cond.:Temp.Comp.1: (Y/N): N

If no temperature compensation is needed, this option can be set inactive (Select ‘N’). In this case D-Determinator switches back tothe beginning screen of "Select sensor / 1: ...".

If the conductivity transmitter cannot perform the temperature compensation, this option should be activated (Select ‘Y’). In thiscase the second sensor must be a temperature sensor. So, the configuration of sensor 2 will allow no other option besidestemperature.

Cond. Temp.Coeff1: 9,99 %/°C

For temperature compensation two values must be entered: the temperature coefficient and the reference temperature. Thetemperature coefficient describes the change of measured conductivity in conjunction with a change in temperature. The data sheetof the installed conductivity sensor should have a value for it’s temperature coefficient.

Cond. Ref.Temp.1: 25,0 °C

The reference temperature defines, at which temperature the conductivity has been calibrated. The data sheet of the conductivitysensor should have a value for the reference temperature.

A positive temperature coefficient describes a rising measured conductivity with rising temperature; the measured value will bereduced to give the correct reading. A negative temperature coefficient describes a falling measured conductivity with risingtemperature. The example diagram below shows different curves for both positive and negative temperature coefficient.

pH- Scale min.1: 00,0

The low end scale of the sensor (analog input 1) is set in a range from 0,0 to 14,0. This is the pH-value necessary to produce theminimum output current (0 mA or 4 mA) by the pH transmitter.

pH- Scale max.1: 14,0 pH

The maximum scale of the sensor (analog input 1) is set in a range from 0,0 to 14,0. This is the pH value necessary to produce20mA output current by the transmitter.

Calibrate-Sensor1: (Y/N): Y

If no calibration is needed, this option can be refused ("N"). In this case D-Determinator switches back to the "Select Sensor”screen. If the sensor has to be calibrated follow the pH sensor supplier’s instructions and enter the values into the D-Determinator.

Calibrate pH=71: 07,1 [Enter]

The first step is calibration at pH = 7, the sensor has to emerged into a pH = 7-solution. The D-Determinator will show themeasured pH value in momentary calibration. If the read out is stable, press ENTER the current measured value will be referred toas 7,0 pH.

Calibrate pH=4/101: 04,1 [Enter]

The second step is calibration at pH = 4 or at pH = 10, the sensor has to emerged into a pH = 4 or pH = 10-solution. The D-Determinator will show the measured value in momentary calibration. If the read out is stable, press ENTER the current measuredvalue will be referred to as 4,0 pH or 10,0 pH. D-Determinator will switch automatically between these values depending whetherthe second calibration value is higher or lower than a pH = 7 value.

Note: On the D-Determinator the "pH-Scale min." should be below pH = 7 and "pH-Scale max." should be abovepH = 7. If calibration is done with pH = 4, then "pH-Scale min." should be below pH = 4. If calibration is done withpH = 10, then "pH-Scale max." should be above pH = 10. Else calibration will give false values. Make sure that the pH= 4, 7, 10 solutions are correct, else calibration will give false values.


Select Sensor1: RedOx

Select Sensor1: ClO2

Configuration of RedOx-sensor (Analog Input 1)




Pressing the SELECT-key can leave every step in configuration. In this case D-Determinator switches back to the "Select Sensor”screen.

RedOx-Scale min.1: -1000 mV

The low end scale of the sensor (analog input 1) is set in a range from -1000 mV to 1000 mV. This is the RedOx potentialnecessary to produce the minimum output current (0 mA or 4 mA) by the transmitter.

RedOx-Scale max.1: 1000 mV

The maximum scale of the sensor (analog input 1) is set in a range from -1000 mV to 1000 mV. This is the RedOx potentialnecessary to produce 20mA output current by the sensor.

Configuration of ClO2-sensor (Analog Input 1)




Pressing the SELECT-key can leave this step in configuration. In this case D-Determinator switches back to the "Select Sensor”screen.

ClO2-Scale max.1: 200,00 ppm

The maximum scale of the sensor (analog input 1) is set in a range from 0 ppm to 200 ppm. This is the ClO2 concentrationnecessary to produce a full scale or 20mA output current by the transmitter.


Select Sensor1: direct

Configuration of Direct (Analog Input 1)




Pressing the SELECT-key can leave this step in configuration. In this case D-Determinator switches back to the "Select Sensor”screen.

Direct Display1: (mA/%) mA

If the input current has to be displayed directly, the option "mA" should be selected.

Press the down arrow key, to toggle between the following choices:

mA : If the input current is to be displayed in mA with at resolution of 0,02 mA. With the minimum valuebeing set in the previous menu selection (“Sel. Current Min.”) and a maximum value of 20mA.

% : If the input current is to be displayed as % of the input range selected with a resolution of 0,1%. Theinput range may be 0-20mA or 4-20mA depending on the "Sel. Current Min." value enteredpreviously. An example would be if the analog input 1 were measuring a current of 8mA, 25,0%would be displayed for a 4-20mA range or 40,0% for a 0-20mA range.


Select sensor type of input 2

Select sensor2: Temp.

The second sensor input (analog input 2) can be connected to different types of sensors. Press the down arrow key, to togglebetween the following choices: This sensor may be fixed depending on what was configured for analog input 1. Such as iftemperature compensation was selected on the conductivity sensor on input 1 then this input must be a temperature sensor.

Temp. : The full-scale range of the temperature sensor can be set freely. This option is chosen automatically ifthe main sensor is set to be a conductivity sensor with additional temperature compensation. In thiscase, the options "RedOx" and "off" cannot be selected.

RedOx : The scale of the RedOx-sensor can be set freely. This option is only possible if the main sensor is setto be a ClO2

sensor or a RedOx Sensor.

off : If no second sensor is used, this input can be deactivated. No additional settings have to be made.


If the options "Temp." or "RedOx" are selected, the minimum current of the sensor has to be set. A selection of 0 mA or 4 mA ispossible depending whether a "live zero" (4-20mA) is used or not (0-20mA)

Configuration of temperature sensor (Analog Input 2)Pressing the SELECT-key can leave this step in configuration. In this case D-Determinator switches back to the "Select Sensor”screen.

Temp.-Scale max.2: 150,0

The maximum scale of the sensor (analog input 2) is set in a range from 0°C to 150°C. This is the temperature necessary toproduce 20mA output current by the temperature transmitter.


Configuration of RedOx-sensor (Analog Input 2)Pressing the SELECT-key can leave every step in configuration. In this case D-Determinator switches back to the "Select Sensor”screen.

Secondary Contr.2: (Y/N): Y

If two RedOx sensors are used, the measured value of the second sensor can be used to supervise the first sensor. The first sensorwill always be the leading sensor regarding the dosing operation. If the "secondary control" option is activated ("Y"), the alarmthresholds can be set at which the D-Determinator will indicate an error when the difference in the values from each sensor exceeda configured amount. If the first sensor is a ClO2 sensor, the output signal of the RedOx sensor will be computed to give a ClO2

concentration. The deviation alarms will be set in terms of a ClO2 concentration (ppm).

Deviation min.2: -1000 mV

The minimum deviation between the two sensors (analog input 2 is lower than analog input 1) is set in a range from -1000 mV to 0mV.

Deviation max.2: 1000 mV

The maximum deviation between the two sensors (analog input 2 is higher than analog input 1) is set in a range from 0 mV to 1000mV.

Alarm Delay Time2: 9999 sec

An alarm will be released whenever the deviation between both inputs (analog input 2 and analog input 1) is lower/ higher thanconfigured Deviation min./max. values. The alarm can be delayed up to 9999 seconds in order to suppress short mismatches thatwould generate nuisance alarms.


Equipment ConfigurationThe second screen in the Configuration Mode is:

Equipment Config Enter

Equipment Configuration Flow Chart

All of the parameters that define the specific operations of the equipment (dosing pumps) will be described in this section of theUser’s Manual.

Referring to the Equipment Configuration flow chart (Appendix A), use the keys on the control panel to respond to the informationon the LCD display (see System Flow Charts and Control Panel Keys).

The first screen in Equipment Configuration is:

Equipm. : 1 2 3 4Mode: R D 0 P

This screen displays the current configuration of each of the four dosing equipment. The different operational modes of the thisequipment have the following meanings:

R analog Regulator (Equipment 1 only) When this mode is configured the D-Determinator will dosechemical to maintain a desired setpoint as measured by thesensor configured on analog input 1.

F volume Fix (Equipment 1-3) In this mode the D-Determinator will dose in a fixed amountof chemical on a fixed time schedule.

C volume fix with secondary Control(Equipment 1 only)

In this mode the D-Determinator will dose in a fixed amountof chemical on a fixed time schedule and issue process alarmsfrom on the analog input connected to channel 1.

D Dependant (Equipment 2,3 only) In this mode the equipment connected to channels 2 and/or 3will dose it’s product in an amount that is calculate from aration of the amount of the main product that was dosed.

PorV

Pump or Valve on(Equipment 4 only)

This configuration is only for a larger pump connected tochannel 4 to provide a faster delivery of chemical into thesystem for initial charge and start-up mode.

0 Off (Equipment 2-4) No dosing equipment is configured on this channel.

Before the system has been configured for the first time, all pump configurations will be set to ‘0’. Press the ENTER key toproceed to the next screen.

Select EquipmentEquip. (1-4): 1

The cursor will be located in the digit field on the LCD display. Press the down arrow key, until ‘1’ appears in the digit field, toconfigure the first piece of equipment (dosing pump). Press the Enter key to proceed.


Setting Equipment Mode (On/ Off)

Equipment Mode1: (I/O) = I

Every piece of equipment (dosing pump) may be activated or deactivated. The operation mode of each piece of equipment will beconfigured later. Rotate between the two choices, by using the down-arrow key.

If you do not want to use this pump on channel 1, you may Disable it by selecting ‘0’. When a pump is disabled, a ‘0’ will occupythat pump’s corresponding position in the ‘Equipment Mode’ display. To activate a pump connected to channel 1 then us thedown arrow keys to select a ‘1’.

When you have made your choice, press the ENTER key to confirm this screen.

Note: If a network of a Master and one or more Slaves are to be configured, care must be taken during configuration of theMaster:Every piece of equipment that is used by the network has to be configured at the Master, even if it is not used by theMaster. Only the Master has information about pump type and flow meter data.If an equipment is not used by the Master but used by one of the Slaves, act as follows:Set equipment to be on, define its data as necessary and to disable it at the Master set the "Operation Mode =Volume Fix (F)" and "Fixed Volume = 0,0 kg" or "Interval Time = 0 sec. With these settings, the equipment isdefined completely but is not dosing at the Master Control itself.

Select flowmeter

Prod. Flowmeter1: (Y/N) = Y

This option would be activated if there is a pulse flowmeters installed in the product dosing piping. The flow meter should beconnected to the corresponding flow meter input connection (i.e. for pump 1, it’s flow meter should be connected to Flow 1).

Flowmeters for equipment 2, 3 (i.e. pumps 2, 3) additional flowmeter may be activated or deactivated. The operation mode ofeach piece of equipment will be configured later. Rotate between the two choices (Yes/No), using the Down-arrow key and pressENTER when done.


Select pump type

Select Pump Type1: (S/P) : S

For every piece of equipment (pump 1-4) the pump type can be selected between "Stroke" and “Permanent" (S/P). When you havemade your choice using the down-arrow key, press the ENTER key to confirm this screen.

If the pump type is selected to be "Stroke" (S), two additional times must be set:

Stroke Time1: 9,9 sec

"Stroke time" defines the length of time the stroke impulse is ON to drive the pump according to it’s specifications.

Pause Time1: 9,9 sec

"Pause Time" defines the pause time between two stroke pulses to produce the specified product flow rate (see parameter "StrokePump Product").

Flow Rate Input / Teach In

Prod.Flow.Rate1: T.I.(Y/N): N

Without use of a flow meter the discharge capacity (Mass Flow) of the pumps (kg/hr) can be set either by entering the flow rate ofthe pump (timed, l/hr or stroked, p/l) and the density of the product (kg/l), or by using a ‘Teach-in’ method. To choose betweenYes / No, toggle with the down arrow key. If a flow meter is used, its calibration is done simultaneously during 'Teach-in'. Ifthere is no flow meter and the Teach-In function is used then these are the screens that will be displayed. So, basically you dosethe chemical or water into a bucket using this feature to determine the flow rate of the dosing pump.

Fill Test Volume1: Start = Enter

Fill Test Volume1: Stop = Enter

Enter Weight1: 000,000 kg

Prod.Flow.Rate1: 250,0 kg/h

If a flow meter is used without the Teach-In calibration, "Flowmeter Product" has to be set (equipment 1-3) instead of the pumpparameters.

Pressing ENTER will start an internal timer and start the chemicaldosing per the current configuration of Stroke time and Pause time.

Pressing ENTER will stop an internal timer and stop the chemicaldosing.

Measure the amount of chemical dosed into the bucket in kilograms andenter it here. This screen will only be active for 1 minute so you mustenter the value in less then a minute or you have to run the test again.

The D-Determinator will now calculate a kg/h from the weightentered and the internal timer value.


Product density will only appear with equipment 1-3 as equipment 4 uses the same product and flowmeteras equipment 1.

Stroke Pump Prod.1: 9999 p/l

OR

Flowmeter Prod.1: 9999 p/l

Product Density1: 1,999 kg/ l

Without a flowmeter one of the following parameters must be set, depending on selected pump type: "Timed Pump Prod" in caseof a permanent pump and "Stroke Pump Prod." in case of a stroke dosing pump. If equipment 4 is selected, these parametersappear always, as equipment 4 uses the same product and flowmeter as equipment 1.

Timed Pump Prod.1: 999,9 l/h


Enter the pulses/l for the stroke pump if no flowmeter isconnected to the system.

Enter the pulses/l for the flowmeter connected to the system.

Enter the product density that will be dosed by the system.


Control of product flowIf a flow meter is used then a minimum and maximum product flow rate can be set. During the dosing of product, flow ismeasured and compared with these limits. Whenever a flow outside these limits is measured, an alarm will be generated.

Min. Prod. Flow1: 9999,9 kg/h

Max. Prod. Flow1: 9999,9 kg/h

This parameter will be set for equipment 4 also if a flowmeter for equipment 1 is used since both pumps share the same flow meter.If equipment 4 has been selected, the configuration is finished now.


Operation Mode

Select Operation ModeIf equipment 1 - 3 are selected, the operation modes can be set using these screens. The screen will display the configurationchoices of the selected equipment (i.e. equipment 1, 2,or 3). The configuration options are different forequipment 1 and equipment 2-3.

The choices for equipment 1 are the following:

Operation Mode1: (R/C/F/D) R

R Analog Regulator (This option is only available for equipment 1)C Volume fix with secondary Control (This option is only available for equipment 1)F Volume FixD Dependant (This option is only available for equipment 2 and 3)

For explanation of the different modes see the following chapters.

Note: The Operation Mode cannot be set for equipment 4, this equipment is used only for Initial Charge dosing of product1 and does not need any of the following settings. The Initial Charge volume is set during configuration ofequipment 1 as this equipment will be used for Initial Charge dosing if equipment 4 is disabled.

Analog RegulatorIn the analog regulator control mode the measured value from analog input 1 is compared to a desired setpoint. Depending on theselected Regulator Control Mode (discussed below) and the dosing operation configured on equipment 1 the D-Determinator willtry to maintain the entered setpoint:

Dosing of product 1 is done in portions defined by the parameters "Dose Time" and "Wait Time". If a dosing process is running, itwill be stopped after "Dose Time". Then the D-Determinator will wait until the end of the "Wait Time" to check the processconditions. If the dosing condition is still valid, dosing will be continued until the setpoint is reached or an alarm is generated.

Dose Time1: 9.999 sec

Wait Time1: 9.999 sec

Setpoint and Deadband are set in same units and scale as defined by the scale of analog input 1. For example if analog input 1 isdefined as conductivity with a range of 0....800 µS then the possible values for Setpoint and Deadband must be within that range,in µS.

Setpoint1: 0000

Deadband1: 0000


If the Setpoint cannot be reached within “Timeout Setpoint” time, an alarm is released and the automatic dosing process is stopped.If the measured value reaches the Setpoint during Initial Charge or Start-Up, these modes are stopped and a warning message isreleased.

Below is the screen to configure the Setpoint Timeout value.

Timeout-Setpoint1: 9999 sec

Reg. Crtl. Mode2: (Pos/Neg) Pos

Pos Positive Measured value should be above SetpointNeg Negative Measured value should be below Setpoint

Control Mode Positive:(Reg.Crtl. Mode = Pos)

• If the measured value is higher than "Setpoint" + "Deadband" dosing ofproduct 1 will be started.

• If the measured value is lower than "Setpoint" dosing of product 1 willbe stopped.

• If the measured value is below the alarm level "Min. Alarm" an alarm isgenerated and the automatic dosing process is stopped. If the measuredvalue is above the alarm level "Max. Alarm" a warning message isgenerated and the automatic dosing process continues.

Control Mode Negative:(Reg.Crtl. Mode =Neg)

• If the measured value is lower than "Setpoint" - "Deadband" dosing ofproduct 1 will be started.

• If the measured value is higher than "Setpoint" dosing of product 1 willbe stopped.

• If the measured value is below the alarm level "Min. Alarm" a warningmessage is generated and the automatic dosing process continues. Ifthe measured value is above the alarm level "Max. Alarm" an alarm isgenerated and the automatic dosing process is stopped.

As with Setpoint and Deadband the alarm levels are set in same units and scale as defined by the scale of analog input 1. Forexample if input 1 is defined as conductivity with a range of 0....800 µS then the possible range for Min./ Max. Alarm is the same.

Min. Alarm1: 0000

Max. Alarm1: 0000

The alarm warning level (Min. Alarm / Max. Alarm, depending on Regulator Control Mode) is not active during Initial Charge orStart-Up.


Volume fixA Volume Fix mode control is open loop dosing of an amount of product per time, independent of any measured values. Twoparameters are necessary: volume and interval time. When an interval starts, a dosing process is started. If the set amount ofproduct has been dosed, the dosing is stopped until the end of the interval time. Then at the next interval time the dosing is startedagain.

Fixed Volume1: 999,999 kg

Interval Time1: 9.999 sec

The consumption of product is controlled via flow meter if possible else the calculation of the consumption is done via time andthe calculated product flow rates of the equipment.

Volume fix + secondary ControlA Volume Fix mode is dosing an amount of product per time independent of any measured values. Two parameters are necessary:volume and interval time. When an interval starts, a dosing process is started. If the set amount of product has been dosed, thedosing is stopped until the end of the interval time. Then the next interval is started again. As a supporting feature, the measuredvalue is used to control the action of D-Determinator. If the measured value exceeds the alarm limits then alarms are generated,but the dosing and control is still maintained by the volume fix dosing operation.

Fixed Volume1: 999,999 kg

Interval Time1: 9999 sec

The consumption of product is controlled via flow meter if possible else the calculation of the consumption is done via time andthe set product flow rates of the equipment.

The alarm levels are set in same units and scale as defined by the scale of analog input 1. For example if analog input 1 is definedas conductivity with a range of 0....800 µS then the possible range for Min./ Max. Alarm is the same.

Min. Alarm1: ?????? ???

Max. Alarm1: ?????? ???

The alarm warning level (Min. Alarm / Max. Alarm, depending on Regulator Control Mode) is not active during Initial Charge orStart-Up.


DependantIn dependant mode, the amount of product 2 or 3 is set in relationship to product 1. If, for example, a value of 0..200 is entered forthe relationship, the equipment will dose, on average, 20% of the mass of this product compared to the mass of product 1.

To prevent the equipment being started too often, a minimum volume is defined. If the need for product 2 or 3 exceeds this limit, adosing process is started dosing the complete necessary amount of product.

min. Volume2: 999,999 kg

Vol. Ratio2: 1,000

The consumption numbers are used to determine when it time to dose, not an actual ratio flow that runs in parallel with product 1,just at a lower flow rate.

The consumption of product is controlled via flow meter if possible else the calculation of the consumption is done via time andthe set product flow rates of the equipment.


Setpoints for Initial Charge and Start-UpFor every piece equipment the amount of product necessary for an initial charge has to be set here. During Initial Charge andStart-Up the measured value in analog input 1 is monitored.

Setp. Init. Ch.1: 999,999 kg

Setp. StartUp1: 999,999 kg

The dosing of the configured Initial Charge/Start-up volumes can be manually activated within the Operation Menu or externallytriggered through the hardware inputs for Initial Charge trigger and Start-up trigger (see Control System Configuration).

Network setting

If it the application requires a CAN-Bus connection between the D-Determinator units. An additional CAN-Bus interface moduleneeds to be purchased along with the D-Determinator to complete a network installation.

If the D-Determinator is equipped with a CAN-Bus interface, this option appears in the menu.

Network setting Enter

The type of operation in the network has to be selected first.

Use Network(M/S/N): M

Three selections are available:M Master This D-Determinator is a Master to other units within the same network.S Slave This D-Determinator is Slave to another units within the same networkN None The CAN-Bus interface will not be used in conjunction with other DiverseyLever Controls

Network ID32

The address within the CAN-Bus network has to be set.

If the D-Determinator is selected to be a "Master" then the address has to be a multiple of 4. A Master will regard all D-Determinators as slave if their address is higher by 1…3 compared to the Master’s address.

Note: If another address is set, it will be reduced to the next lowest multiple of four.Example: If the Master address is set to be 19 it will be changed automatically to 16 if ENTER is pressed.

If a D-Determinator is selected to be a "Slave" it’s address must not be a multiple of four. This slave will regard a D-Determinatoras Master if his address is the next lowest multiple of four compared with his own address. Care must be taken not to assign twoslaves to the same address.

Note: If a multiple of four is set, the address will be incremented by one.Example: If the slave address is set to be 20 it will be changed automatically to 21 if ENTER is pressed.

Network Example: If the Master D-Determinator’s CAN-Bus Address is 32 then it’s Slave Addresses will be 33, 34, 35

(In the screen example above: ClO2 sensor is connected to analog input 1, D-Determinator is dosing in Initial Charge/ Start-Up/Manual Mode with a remaining volume of 65,9 kg is to be dosed)


Automatic dosingDuring automatic dosing the operation depends on the selected operation mode, see chapter "Equipment Configuration", and onthe configuration of the equipment.

Once configured Equipment 1 (main product) can dose product with these control algorithms, "Analog Regulator", "Volume Fix +2nd Control" or "Volume Fix", see below for details of these modes. Equipment 2 and 3 can use, simultaneously to Equipment 1,these control algorithms "Volume Fix" or "Dependant" mode.

Analog RegulatorThe measured value from analog input 1 is compared to a setpoint. Depending on the selected Regulator Control Mode thefollowing happens:

Control Mode Positive:(Reg.Crtl. Mode = Pos)

• If the measured value on analog input 1is higher than "Setpoint" +"Deadband" dosing of product 1 will be started.

• If the measured value on analog input 1is lower than "Setpoint" dosingof product 1 will be stopped.

• If the measured value on analog input 1is below the alarm level "Min.Alarm" an alarm is generated and the automatic dosing process isstopped. If the measured value on analog input 1is above the alarmlevel "Max. Alarm" a warning message is generated and the automaticdosing process continues.

Control Mode Negative:(Reg.Crtl. Mode = Neg)

• If the measured value on analog input 1is lower than "Setpoint" -"Deadband" dosing of product 1 will be started.

• If the measured value on analog input 1is higher than "Setpoint" dosingof product 1 will be stopped.

• If the measured value on analog input 1is below the alarm level "Min.Alarm" a warning message is generated and the automatic dosingprocess continues. If the measured value on analog input 1is above thealarm level "Max. Alarm" an alarm is generated and the automaticdosing process is stopped.

Dosing of product 1 is done in portions defined by the parameters "Dose Time" and "Wait Time". If a dosing process is running, itwill be stopped after "Dose Time". D-Determinator will wait until the end of "Wait Time". If the dosing condition is still valid(see table above for dosing conditions), dosing will continue.

The consumption of product is monitored via flowmeters if possible else the calculation of the consumption is done via time andthe calculated product flow rates of the equipment. The consumption counters are updated each time the product is dosed.

If the Setpoint cannot be reached within the dosing time, an alarm is generated and the automatic dosing process is stopped untilthe process operator acknowledges the alarm by hitting the ENTER key.

Volume fix + secondary ControlA Volume Fix mode is dosing an amount of product per time independent of any measured values. Two parameters are necessary:volume and interval time. When an interval starts, the main dosing process is started. If the set amount of product has been dosedwithin the interval time, the dosing is stopped until the end of the interval time. Then at the next interval the dosing process isstarted, again. As a supporting feature, the measured value is used to control the action of D-Determinator.

The consumption of product is monitored via flowmeters if possible else the calculation of the consumption is done via time andthe calculated product flow rates of the equipment. The consumption counters are updated each time the product is dosed.


As a supporting feature, the measured value is used to control the action of D-Determinator. Depending on the selected RegulatorControl mode the following happens:

Reg.Crtl. Mode = Pos.: If the measured value on analog input 1is below the alarm level "Min. Alarm" an alarm is released andthe automatic dosing process is stopped. If the measured value is above the alarm level "Max. Alarm" awarning message is released and the automatic dosing process continues. The warning message willremain on the screen until the process operator acknowledges it by hitting the ENTER key.

Reg.Crtl. Mode =neg.: If the measured value on analog input 1is below the alarm level "Min. Alarm" a warning message isreleased and the automatic dosing process continues. If the measured value is above the alarm level"Max. Alarm." an alarm is released and the automatic dosing process is stopped. The warning messagewill remain on the screen until the process operator acknowledges it by hitting the ENTER key.

Volume fixA Volume Fix mode is dosing an amount of product per time independent of any measured values. Two parameters are necessary:volume and interval time. When an interval starts, a dosing process is started. If the set amount of product has been dosed, thedosing is stopped until the end of the interval time. Then during the next interval the dosing process is started, again.

The consumption of product is controlled via flowmeter if possible else the calculation of the consumption is done via time and theset product flow rates of the equipment.

DependantIn dependant mode, the amount of product 2 or 3 is set in relationship to product 1. If, for example, a value of 0,200 is entered forthe relationship, the equipment will dose, on average, 20% of the mass of his product compared to the mass of product 1. Thisamount is based on the consumption values not on simultaneous ratio feeding.

To prevent the equipment being started too often, a minimum volume is defined. If the need for product 2/3 exceeds this limit, adosing process is started dosing the complete necessary amount of product.

The consumption of product is monitored via flowmeters if possible; if not the calculation of the consumption is done via time andthe calculated product flow rate of the equipment.

Dosing an Initial Charge/ Start-UpDuring Initial Charge/ Start-Up a preset volume is dosed, it is possible to dose the initial charge or the start-up charge with alldosing equipment (1-4). The equipment will run at maximum flowrate to perform the initial charge or the start-up charge asquickly as possible. Equipment 4 is a special case because it will dose the main product with a larger pump if configured.

To start an Initial Charge or a Start-Up dosing, externally, two input signals (Release Trigger plus Initial Charge or ReleaseTrigger plus Start-Up) are necessary. Once an Initial Charge or Start-Up is started externally the D-Determinator will dose theentire amount configured unless the Release Trigger signal is lost.

If an Initial Charge or a Start-Up dosing is running, the one of following screens will appear in the menu.

Conduct. Init.Ch0555 mS

Pressing the SELECT-key will lead to a screen allowing to stop the Initial Charge/ Start-Up Mode manually. If it was triggeredexternally.


Initial ChargeStop = Select

Start-Up ModeStop = Select

Initial Charge ENTER

Start-Up Mode ENTER

These modes may be started manually, also. If the Release Trigger is active, both following screens will appear in the menu. Theoperator can loop through the menu by hitting the SELECT key.

Initial Charge ENTER

Start-Up Mode ENTER

Pressing the ENTER-key will lead to a screen allowing to start the Initial Charge/ Start-Up Mode manually

Initial ChargeStart = Enter

Start-Up ModeStart = Enter

The volumes to be dosed and the selected equipment have to be set in Configuration Mode. Each piece of equipment (1-4) thathave an initial charge or start-up amount configured will dose that product when one of these modes are selected, either through thescreen and operator selection or by an external trigger.

In these modes the warning level is deactivated (either Min. Alarm" or "Max. Alarm" depending on Control Mode) only the Alarmlevel will be active (see chapter "Equipment Configuration").

During Initial Charge, equipment 4 is used instead of equipment 1 (if this equipment is configured to be "ON").

If the Operation Mode is "Analog Regulator" these modes are stopped once the setpoint is reached, D-Determinator will continuein automatic mode. In this case a warning message will be released.

If the Operation Mode is "Volume fix + 2nd Control" these modes are stopped once the alarm level is reached. In this case analarm message will be released and the process will be stopped.

If the Operation Mode is "Volume fix " no alarm level are activate.

Initial Charge/ Start-Up Mode are finished once the defined volumes of all products have been dosed.

Manual dosingDuring Manual Mode a preset volume is dosed, it is possible to choose between Equipment 1, 2 and 3. The equipment will run atmaximum flowrate to deliver the desired amount of product as quickly as possible. The dosed volume is set while starting ManualMode operation.

ENTER

ENTERThese second screens can beleft without stopping InitialCharge / Start-Up by pressingthe ENTER-key


In this mode the warning levels are deactivated (either Min. Alarm" or "Max. Alarm" depending on Regulator Control Mode) onlythe Alarm level will be active (see chapter "Equipment Configuration").

the following screen will appear in the menu after viewing the consumption:

Manual Mode ENTER

Pressing the ENTER-key will lead to operator to screens allowing them to enter the necessary information to complete the desiredManual dose operation:

The equipment number and the desired product volume have to be selected and entered, respectively:

Manual ModeEquipm. (1..3):2

Manual Volume2: 999,9kg

The Manual Mode has to be started by pressing the ENTER-key.

Manual Mode2: Start = Enter

While dosing manually, the remaining time can be displayed by pressing the "⇒"-key during normal display. If the Manual Modeis already running, a different screen will appear when selecting this mode.It can be stopped then by pressing the SELECT-key

Manual Mode2: Stop = Select

Pressing "ENTER" continues dosing and returns to normal operation.Pressing "SELECT" stops the manual dosing and returns to normal operation.


Operation as a "Slave"If a D-Determinator is used as Slave the following differences in operation will occur:

− The sensor input 1 is of the same type as defined at the Master.

− The equipment will always be "permanent" as valves will be controlled and not dosing pumps.

− The valves 1-4 corresponding to equipment 1-4 have to be connected to the power outputs, the stroke outputs will be inactive.

− Level alarm, data of equipment and flow sensor inputs will not be used, these are only necessary for the Master. If the networkaddress of a D-Determinator is set to a Slave-Address, these items will be skipped during configuration.

− During Initial Charge output 4 (equipment 4 = valve 4) will be activated. This allows to use a separate valve for dosing theInitial Charge. If the same valve (valve 1) is used to control the flow of product 1 during normal operation and during InitialCharge, output 4 has to connected to output 1

Network operationIf multiple D-Determinators are coupled together using the CAN-Bus network some rules of operation are necessary:

− Every slave will send a request of product to its Master if product is needed. The Master will do the same (internally).

− The unit to be serviced first is the unit that sends the first request (FIFO - principle: first in - first out).

− During Wait Time (Regulator Mode) another unit may be serviced.

− An Initial Charge or a Start-Up dosing may not be interrupted by another unit.

−


Troubleshooting

Alarms and WarningsThere are two types of messages: Alarms and Warnings.

Alarm: If a condition in the process triggers an alarm the dosing process will be stopped until the alarm is acknowledged bypressing the ENTER-key.

Warning: If a warning message is generated the D-Determinator continues with normal operation. The warning message willstay on the display until it is acknowledged by pressing the ENTER-key

An alarm / warning will always be signaled in the top line of the display. If possible, the bottom line will continue to show themeasured values of both analog inputs.

The last alarm or warning that occurred will be displayed. If an alarm is activated, no warning message will override this display.

Alarm messsages

The preset volume could not be dosed within the set interval time. (both Volume fixed Modes).The demand for volume is higher then ten times the preset minimum volume (Dependant Mode)."X" denotes the equipment (X=1, 2 or 3) generating this error

E7 Level Alarm X????? ??? ???? ??

The low level alarm input from product "X" has been activated (X=1, 2, 3). An alarm is generated if the low level alarm input isactivated (the contact is open) indicating that the related equipment/product is empty and the process is requesting product.


Warning messages

W1 Low Flow Pr.X????? ??? ???? ??

The flow of product "X" (X=1, 2, 3) has been measured and is below the set minimum flowrate.

W2 High Flow Pr.X????? ??? ???? ??

The flow of product "X" (X=1, 2, 3) has been measured and is above the set maximum flowrate,.

W5 XXXX min.????? ??? ???? ??

The measured value is below the low warning threshold (Regulator Control Mode = negative). "XXXX" denotes the selectedinput type, e.g. "RedOx" or "Cond.".

W5 XXXX max.????? ??? ???? ??

The measured value is above the high warning threshold (Regulator Control Mode = positive) ). "XXXX" denotes the selectedinput type, e.g. "RedOx" or "Cond.".

W7 Level Alarm X????? ??? ???? ??

The low level alarm input of product "X" has been activated (X=1, 2, 3). A warning is generated if the low level alarm input isactivated, indicating the related equipment/ product is empty and the process is not requesting product. This error exists aswarning and alarm. As longs as a product is not demanded, no alarm is generated because a Master not needing this productshould not be stopped by a level alarm of this product. In case of a product rarely needed, the equipment may continue working aslong as no actual demand appears.


System Not FunctionalIf no display appears on the LCD screen when the system is switched on:

• check all electrical connections

• ensure that all fuses are functioning and not broken

• ensure that the power supply has not been disrupted

If the system still does not function, please contact the service department.

If the display is working, check inputs and the reaction of the outputs with the integrated "I/O-Test" function
