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.

By means the "Delay" parameter, you can specify the time elapsing before the input enabled the range 0.
You can select one the following actions:
1.01s performs action after set
15.e..5.5
Delay 0. Trip reset: when the input enabled for the specified delay trip reset performed

1 120/K enu
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. the action that takes place after the programmed delay, when the input enabled (on
high low level). low input enabling level
