4.3.1  Pre-alarm threshold

Pre‑alarm limit value (default value: 1.00 MΩ).

If the resistance value if the insulation value falls below the set threshold, the WARNING signal activates.

The overcoming of the threshold is locally signalled by turning on the LED WARNING (yellow).

The same information is transferred to the supervisor through the data connection.

If present, the remote signalling system (optional) activates the relay by exchanging the 

status of the respective contacts NO-NC.
