Corrected insulation fault signal (Corr. Flt. Signal)

You can set the corrected insulation fault signal acknowledgement as per the usage of loads connected to the relay.

To facilitate insulation fault correction, the insulation alarm relay can be reactivated for 3 seconds when the insulation level rises above the setup threshold. This makes it easier to locate the insulation fault when using the method that involves opening each of the circuit breakers in turn. The circuit breakers may be located at some distance from the device, the external signal allows you to identify and locate the insulation fault when working remotely.

The allowed values for this parameter are ON and OFF. The default value is OFF.

In system configurations where the insulation alarm relay is connected to an external signaling device (for example, horns or lamps), the relays are reverted back to their normal position, depending on their setup, when the insulation alarm is acknowledged.

Corrected insulation fault signal set to ON

1	An insulation fault is detected in the power system.
2	Once T has elapsed (alarm time delay), the device switches to the insulation alarm status. The insulation alarm relay changes over and the alarm LED lights up.
3	Press the button to acknowledge the insulation alarm. The insulation alarm relay reverts to its initial status.
4	When the insulation fault has been corrected, the insulation alarm relay changes over for 3s to confirm that insulation fault is located (For example: By opening circuit breakers to find the insulation fault).
5	The device reverts to normal status.
