Safety instructionsafety instructions

Prevent measurement errors!When a monitored IT system contains galvanically coupled DC circuits, aninsulation fault can only be detected correctly if the rectifier valves (e.g.rectifier diode, thyristors, IGBTs, frequency inverters, …) carry a minimumcurrent of > 10 mA.

Unspecified frequency rangeWhen connecting to an IT system with frequency components below thespecified frequency range, the response times and response values maydiffer from the indicated technical data. However, depending on the ap-plication and the selected measurement method, continuous insulationmonitoring is also possible in this frequency range.There is no influence on the insulation monitoring for IT systems with fre-quency components above the specified frequency range, e.g. within therange of typical switching frequencies of frequency inverters (2…20 kHz).

.4 Insulation fault locationn additional function of the ISOMETER® in combination with the EDS is the selective in-lation fault location. Therefore, the ISOMETER® generates a periodic locating current af-r the values has fallen below the set response value Ran2 (LED ALARM 2). Thereby, the stem conductors are alternately connected to earth via a defined resistance. The result-g locating current depends on the size of the existing insulation fault and the system

oltage. It is limited by the ISOMETER® depending on the settings. The insulation fault is lectively located by means of the EDS and the measuring current transformer connect-

d to it. The locating current flows from the locating current injector via the live lines to e insulation fault position taking the shortest way. From there, it flows through the in-lation fault and the conductor PE back to the ISOMETER®. This locating current pulse is

etected by the measuring current transformer on the insulation fault path and signalled y the connected EDS.or the duration of the insulation fault location, the function of the insulation monitoring evice is deactivated. If during the insulation fault location the locating current falls be-w the value measurable by the EDS, the insulation fault location is ended by the OMETER®.

Commissioning. Commissioning

.1 General initial commissioning process. Check that the ISOMETER® is properly connected to the system to be monitored.

. Connect the supply voltage to the ISOMETER®. Adjust the device using the commis-sioning wizard. Afterwards, the ISOMETER® performs a self test in four steps. The alarm relays are not checked during this test. After completion of the test, the meas-ured insulation resistance is shown on the display. If the value exceeds the response values indicated in the lowest line of the display, the message "OK" will additionally be displayed.

. Check the ISOMETER® in the system being monitored, e.g. using a suitable resistance to earth.

fter setting the response value Ran2 for alarm 2, the device starts a self test, makes the rst measurement and outputs the measured insulation resistance values of the IT sys-m being monitored, then commissioning is completed.

For customer-specific configured devices, the commissioning wizardmight be deactivated and cannot be run. In this case, the device is preset.However, the commissioning wizard can be started as described at“Recommissioning” on page 35.

Observe device status!The device is in an alarm state until initial commissioning has beencompleted.

1.5 BS bushe BS bus is used to extend Bender measuring devices (e.g. ISOMETER®) with Bender sen-

r devices (e.g. EDS). It is an RS-485 interface with a specially developed protocol for ender devices. On the BS bus, the transmission of alarm messages takes priority over the ansmission of all other messages. For further information, refer to the BS bus manual ocument number: D00278) at www.bender.de/manuals.

aster-slave principle

When connecting more than ten EDS44…-L to the BS bus, the wiring mustbe shockproof.

When using interface converters, a galvanic separation is required.

The compatibility of the BS bus and the BMS bus is restricted!

An ISOMETER® can administer a maximum of 255 EDS channels. There-fore, if an EDS has 12 channels, a maximum of 21 EDS devices can be con-nected via BS bus and BB bus (max. 2).

Special functions for couple3. Special functions for coupled IT systems

3.1 Particularities when monitoring coupled IT systemshen using ISOMETER®s in IT systems, make sure that only one active ISOMETER® is con-

ected in each interconnected system. If several ISOMETER®s are to be connected to the system, ensure that only one ISOMETER® is active in the IT system via system isolation sing the digital input or Ethernet (ISOnet function).

IT systems are interconnected via coupling switches, make sure that ISOMETER®s not rrently used are disconnected from the IT system and deactivated.

systems coupled via diodes or capacitances may also influence the insulation monitor-g process so that a central control of the different ISOMETER®s is required.

3.2 System isolation via digital input with two coupled systems

In order to deactivate the ISOMETER® via one of the digital inputs, the cou-pling switch must have a free contact.

If IT systems are interconnected via coupling switches, one ISOMETER® al-ways remains inactive. Insulation fault location in the IT system of the in-active ISOMETER® is only possible when the associated EDS are in automode (see “Setting EDS mode” on page 34). In addition, insulation faultlocation with a portable EDS must be activated for the active ISOMETER®(setting: Use portable EDS = on, see “Using a portable EDS” on page 54).

Via the X1 connector, the ISing functions can be deactivbe set to "Device inactive".

The IP address of the standard gateway must suit the subnet mask, so thatthe ISOnet function can operate correctly.

Special functions for couplepecial functions for coupled IT systems

3.3 System isolation via ISOnethe ISOnet function ensures via an Ethernet connection that only one ISOMETER® of the terconnection is active when several ISOMETER®s are connected to an IT system.

For several ISOMETER®s to be able to measure in the same ISOnet inter-connection, the settings for the BCOM system name and the BCOM sub-system have to be the same. Only the device address has to be different. Ifthis is not taken into account, the ISOnet function will not work.

If the ISOnet function is deactivated in an ISOMETER® in an ISOnet inter-connection, it will measure continuously and will not forward measuringcommands to the next device in the interconnection.

In comparison to a solution with coupling switches and function input,the response time will be extended because the measurement in the IT sys-tem is not carried out continuously.

The addresses of the ISOMETER®s in the ISOnet interconnection can be se-lected at will. The addresses do not have to be subsequent but they haveto differ from each other.

If in addition to the ISOnet interconnection the digital inputs are wiredand a device is deactivated via a digital input, the device will forward themeasuring authorisation until the signal at the digital input disappears.

or the ISOnet function, the following settings are made in the menu: Alarm settings -> ONet -> ISONet = BCOM. The ISOnet function of all ISOMETER®s existing in the system as to be activated and the number of devices has to be determined. lso the parameters of the Ethernet (DHCP on or IP address, subnet mask and default ateway) and BCOM have to be set so that the devices in the ISOnet interconnection can

mmunicate with each other.

fter starting the system, the devices initialise. The initialisation phase ends when the nfigured number of devices has been reached. Then, the device starts with a measur-g cycle at the lowest address. When an ISOMETER® has finished one measuring cycle, e authorisation for insulation measurement is forwarded to the ISOMETER® with the

ext higher address. While one ISOMETER® is measuring, all other ISOMETER®s are sepa-ted from the system via internal system isolation switches. By limiting to one subsystem

is possible to have several ISOnet interconnections running in one system.

a single device fails, the remaining ISOMETER®s continue the ISOnet operation. For the ilure of one device, two scenarios are possible:

• A device fails during the measuring procedure.After timeout, another device takes over the measuring function. In this way, all devices monitor each other.

• The device fails in the inactive mode.When forwarding the measuring authorisation, the device is skipped and the next device carries out the measurement.

a device that has failed before returns, it is taken into the interconnection again and will ave its turn during the next run.
