reset it
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..7 PR120/K module menu
The PR120/K fitted with four relays having contacts named K51/p1, K51/p2, K51/p3 and K51/p4 which can signal different situations selectable
by the user from among those given the standard list, whereas customizations can programmed selecting "custom" the menu and
setting the signal required with PDA, SD-Testbus PR010/T.3
Delay 0. low input enabling level
2.3.01s Deliberate delay before activating the contact
NO/NC NO/NC Contact normally-open (NO) normally-closed
Latch ON/OFF With the contact "ON", once has been activated it
stays switched.
