Input
Polarity Active low
Active high
Function Generic associated action
Outside trip releases the circuit-breaker
Reset trip resets the data after trip
Set switches from set set (for PR123/DC only)
Local forces the local status the protection (local/remote)
Signal reset programmable contact reset
Energy reset energy meter reset
Delay 0. The figure shows two cases, and which the input's status active;
in case the input does not stay valid beyond the enabling delay the associated action does not take place, whereas case the action takes
place after the preset delay.3.1 Input configuration settings
You can select the level which consider the input enabled:
