HAZARD CATE !R"E# A$D #PEC"A% #&M'!%#

Read these instructions carefully and look at the equipment to becomefamiliar with the device before trying to install, operate, service or maintainit. The following special messages may appear throughout this bulletin or onthe equipment to warn of potential hazards or to call attention to informationthat clarifies or simplifies a procedure.

The addition of either symbol to a !anger" or #arning" safety labelindicates that an electrical hazard e$ists which will result in personal in%ury if the instructions are not followed.

This is the safety alert symbol. It is used to alert you to potential personalin%ury hazards. &bey all safety messages that follow this symbol to avoidpossible in%ury or death.

DA$ ERDA$ ER indicates an imminently hazardous situation which, if notavoided, w(ll re)ult (n death or serious in%ury.

*AR$"$*AR$"$ indicates a potentially hazardous situation which, if notavoided, can re)ult (n death or serious in%ury.

CA+T"!$CA+T"!$ indicates a potentially hazardous situation which, if notavoided, can re)ult (n minor or moderate in%ury.

CA+T"!$CA+T"!$ , used without the safety alert symbol, indicates a potentiallyhazardous situation which, if not avoided, can re)ult (n propertydamage.NOTE: Provides additional information to clarify or simplify a procedure.

Calculat(on Met o4)

!emand power is accumulated power

during a specified period divided by thelength of that period. /ow the powermeter performs this calculation dependson the method you select. To becompatible with electric utility billingpractices, the power meter providesblock interval demand. The defaultdemand calculation is set to rolling blockwith a -Cminute intervals and -subintervals.

Block Interval !emandIn the block interval demand method,you select a block" of time that the

power meter uses for the demand calculation. 7ou choose how the power

meter handles that block of time Hinterval . Three different modes arepossible0

1 #l(4(n 'loc? . In the sliding block interval, you select an interval from to9? minutes Hin Cminute increments . )election for subinterval is notrequired, but configuration software automatically sets a subinterval. If theinterval is ≤ - minutes, the subinterval is - seconds. If the interval isQ - minutes, the subinterval is 9? seconds. The power meter displays thedemand value for the last completed interval.

1 ,(:e4 'loc? . In the fi$ed block interval, you select an interval from to 9?minutes Hin Cminute increments . or the demand to be calculated as afi$ed block, the subinterval value has to be set to . The power metercalculates and updates the demand at the end of each interval.

1 Roll(n 'loc? . In the rolling block interval, you select an interval and asubinterval. The subinterval must divide evenly into the interval to thesecond. The value here has to be Q . or e$ample, you might set 6subintervals for a -Cminute interval. The meter will calculate thesubinterval period to be ;.- minutes or -? seconds. !emand is updatedat each subinterval . The power meter displays the demand value for thelast completed interval.

igure G illustrates the three ways to calculate demand power usingthe block method. or illustration purposes, the interval is set to -minutes.

Pea? De8an4 In nonvolatile memory, the power meter maintains a running ma$imum forpower and current demand values, called peak demand." The peak isthe highest average for each of these readings0 per phase currentdemand, k#!, k35R!, and k35! since the last reset. Table G 6 onpage 9 lists the available peak demand readings from the power meter.

7ou can reset peak demand values from the power meter display. romthe 4ain 4enu, select 45I(T Q R')'T Q !4!.

7ou should reset peak demand after changes to basic meter setup, suchas *T ratio or system type.

De8an4 Current Calculat(on Met o4) The power meter calculates demand current using the thermal demandmethod. The default interval is - minutes, but you can set the demandcurrent interval between and 9? minutes in Cminute increments.

Thermal !emand The thermal demand method calculates the demand based on a thermalresponse, which mimics thermal demand meters. The demandcalculation updates at the end of each interval. 7ou select the demandinterval from to 9? minutes Hin Cminute increments .

5bnormal readings in an installed meter can sometimes signify improperwiring. This appendi$ is provided as an aid in troubleshooting potentialwiring problems.

$!TE

Theinformation in

this appendi$ is intended to be general in nature and covers a variety ofmetering devices.

The +ower 4eter ; ? does not display )( ne4 readings for+ower, 'ngergy, or +ower actor. Throughout this appendi$,when values are stated in terms of positive, negative, or lagging,for the +ower 4eter ; ?, those readings are absolute.

#ECT"!$ " +#"$ TH"# +"DE The following sections contain *ase" tables showing a variety of symptoms and probable causes. The symptoms listed are ideal," andsome %udgment should be e$ercised when troubleshooting. or e$ample, if the k# reading is 6-, but you know that it should be about 8?? k#, go to atable where k# J ?" is listed as one of the symptoms.

)ection II0 *ommon +roblems for 8C#ire and C#ire )ystems " addressessymptoms and possible causes that occur regardless of system type.*heck this section first. If the symptoms are more complicated, proceed to

)ection III0 8C#ire )ystem Troubleshooting" or )ection I30 C#ire )ystemTroubleshooting" as is appropriate.

Because it is nearly impossible to address all combinations of multiplewiring mistakes or other problems that can occur He.g., blown +T fuses,missing +T neutral ground connection, etc. , this guide generally addressesonly one wiring problem at a time.

Before trying to troubleshoot wiring problems, it is imperative that allinstantaneous readings be available for reference. )pecifically thosereadings should include the following0

1 lineCtoCline voltages

1 lineCtoCneutralvoltages

1 phase currents

1 power factor

1 k#

1 k35R

1 k35

* at () $or8alK 4ost power systems have a lagging Hinductive power factor. The only timea leading power factor is e$pected is if power factor correction capacitorsare switched in or overCe$cited synchronous motors with enoughcapacitive k35R) onCline to overcorrect the power factor to leading. )omeuninterruptable power supplies H:+) also produce a leading powerfactor.

Y(ormalY lagging power system readings are as follows0

1+hase currents appro$imately equal

1+hase voltages appro$imately equal

5 quick check for proper readings consists of k# comparisons Hcalculatedusing the equation above and compared to the meter reading and areasonable lagging 8Cphase average power factor reading. If these checksare okay, there is little reason to continue to check for wiring problems.
