Insulation alarm (Ins. Alarm) and preventive insulation alarm (Prev. Alarm) thresholds

You can set the insulation alarm and preventive insulation alarm threshold values as per the level of insulation of the application you monitor.

Parameter Allowed Values Default Value
Ins. Alarm (Insulation alarm threshold) 0.04...500 kΩ 1 kΩ
Prev. Alarm (Preventive insulation alarm threshold)
  • 1 kΩ...1 MΩ

  • OFF


When the device is powered up, it retrieves the last preventive insulation alarm and insulation alarm threshold values recorded.

NOTE: The preventive insulation alarm threshold must always be higher than the insulation alarm threshold.

An insulation alarm is cleared when the insulation level reaches 20% above the threshold.
