  • Optional slave indicator
Application
The digitally controlled KCM163x series monitors insulation level between a non-grounded (IT) AC mains and its protective earth, regardless of whether the mains is live or non-live (standby). 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 ONE KCM163x can be connected to each IT-system.
The ohmmeter and the triple-zone status LEDs give at a glance the clear safety message:
  • ALARM
  • WARNING
  • HEALTHY
General
IDV MEASURING PRINCIPLE

Insulation is measured between the complete galvanically interconnected AC network and its protective earth.

The unit injects a sequentially coded measuring 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 the AC network.

Trip levels and delays are settable on unit front. 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 1.4kVDC, and incorrect measurements caused by the unit’s input impedance are avoided.
OUTPUTS
All F versions have an isolated analogue output proportional to insulation level. If output is used for remote meter reading, we recommend 0-1mA for the slave indicator.
SAFETY
When a voltage adapter (CHx or ANx) is used the signal to terminals 4 and 6 on KCM163x is limited to a safe level, avoiding any dangerous voltage exposure to personnel.
The KCM163x range is designed to comply with specification AODC035 “Code of Practice for the Safe Use of Electricity Under Water” issued by IMCA.
NOTE
Special versions of the KCM163x are available as:
KCM163xM series 
Insulation guard with DC detection function, protected against high-energy DC voltage imposed on the monitored AC supply. 
KCM263x series
Insulation Guards with measuring loop continuity monitoring.
INTELLIGENT SETTING ASSISTANCE
KCM163x has a built-in Assistance tool for setting/verification of the trip levels and the analogue output.When either the Warning or Alarm potentiometer on the front is operated by user, the slave meter goes into Assistance Mode and meter reading and analogue output will reflect the potentiometer setting.
Reset / Paralleling Disable Function
KCM163x has a built-in disable function (available only when DC Aux. Supply is applied). When connecting two or more IT-networks together only one unit can be active, the other(s) must be disabled. When unit is disabled the power led will flash every 2 seconds to indicate that unit is inactive.
