Insulation monitoring device for unearthed

AC/DC control circuits (IT systems)

The currently measured insulation resistance is indicated on the LC display. In this way any changes, for example when circuits are connected to the system, can be recognised

easily. When the value falls below the preset response values, the response delay “ton” starts. Once the response delay “ton” has elapsed, the alarm relays “K1/K2” switch and the

alarm LEDs “AL1/AL2” light up. Two separately adjustable response values/alarm relays allow a distinction to be made between prewarning and alarm. If the insulation resistance

exceeds the release value (response value plus hysteresis), the alarm relays return to their initial position. Insulation faults are distinguished according to AC and DC faults (indication ±).

In the event of insulation faults on the plus or minus conductor, the corresponding +/- symbol is activated on the display. If the fault memory is enabled, the alarm relays remain in the alarm state until the reset button is pressed or until the supply voltage is switched off.

The device function can be tested using the test button. The parameterisation of the device can be carried out via the LC display or the function keys integrated in the front plate.
