The unit is for land, marine, offshore, sub-sea and ocean floor use. An AC or DC auxiliary voltage is required for the unit, if powered from a separate source the network can also be monitored during standby conditions. Only OE KPMx can be connected to each IT-system. The ohmmeter and the triple-zone status LEDs give at a glance the clear safety message: - ALARM (red zone) - WARIG (yellow zone) - HEALTHY (g reen zone) ITELLIGET SETTIGASSISTACE KPMx has a built-in Assistance tool for setting/verification of the trip levels and the analogue output. When either the Warning or Alarm potmeter on the rear is operated by user, the meter goes into Assistance Mode and meter reading and analogue output will reflect the potmeter setting. How to set alarmlevels: Firstly adjust potmeter fully clockwise (see that meter goes to the top), then adjust potmeter down to required Warning or Alarm setpoint. Without any movement of potmeters, the meter will revert to normal Insulation Monitoring Mode after approximately seconds. How to test analogue output signal: Adjust any trip level potmeter to activate Assistance Mode. Example: On a -20mA output, adjust potmeter fully anti clockwise for maand fully clockwise for 20mA. The KPMx range is designed to comply with specification AODC05 Code of Practice for the Safe Use of Electricity Under Water issued by IMCA. The unit meetsiec0092-50 and the relevantenvironmental and EMC tests specified in IEC008/0092 and IEC00/05 respectively, to complywiththe requirementsofthemajorclassification Societies. General IDV MEASURIG PRICIPLE Insulation is measured between the complete galvanically interconnected AC network and its protective earth. The unit injects a DC voltage signal into the monitored system. The signal flows to ground via the path of the insulation fault, the level of flow indicates the insulation resistance. The measuring accuracy is not influenced by any normal kind of load attached to theac network. Trip levels and delays are settable on unit rear. A trip LED flashes when the trip level is passed, the relay trips when the delay has elapsed. The timer resets if the fault is removed during countdown. MEGGER SAFE When auxiliary power is OFF the unit input is automatically protected against megger test voltages up to.kvdc, and incorrect measurements caused by the unit s input impedance are avoided. OUTPUTS All F versions have an isolated analogue output proportional to meter reading. If output is used for remote meter reading, we recommend 0-mAfor the slave indicator. SAFETY When a voltage adapter (CHx, Ax or ARx) is used the signal to terminals and on KPMx and KPM5x is limited to a safe level, avoiding any dangerous voltage exposure to personnel. OTE Special versions of the KPM and KPM are available as: KPMM & KPMM - Insulation guard with DC detection function, protected against high-energy DC voltage imposed on the monitoredac supply. KPM2x & KPM2x - Insulation guard with measuring loop continuity monitoring.
