Insulation alarm relay (Ins. Al. Relay)

You can set the insulation alarm relay mode depending on the status of insulation.

To access the setting, select Menu > Settings > I/O Config.

  • Parameter: Relay

  • Allowed values: FS / Std.

  • Default: FS

The insulation alarm relay is deactivated (de-energized) in the following cases:

  • Insulation fault has been detected.

  • The product has a malfunction.

  • The auxiliary voltage of the power supply is accidentally lost.

  • After the insulation fault disappears, the insulation alarm relay is activated for 3 seconds. This makes it easier to locate the fault when using the method that involves opening each of the circuit breakers in turn. Given that the circuit breakers may be located at some distance from the device, the audible signal allows you to identify and locate the fault from a distance.

NOTE: When the Alarm relay acknowledge is OFF, the insulation alarm relay will not be activated for 3 seconds.
