I tried to simulate undervoltage/overvoltage protection with 7sj804* using omicron. My protection settings are :

U<pick up 45V U>pick up 65V

T U<Time delay 2,5s T U>Time delay 3,5s

U<<pick up 30V U>>pick up 120V

T U<<Time delay 0,5s T U>>Time delay 0,5s

I have applied 50V to relay and it tripped. So i changed current supervision (5120A) status ON to OFF then my problem began. Binary outputs 3 and 4 stays constantly closed and fault leds 7 8 are on. I can not send any parameters to relay because relay sees fault constantly. When i restart the relay, pick up and trip action performs again and again. Also i can not initialize the relay. What can i do else?

With best regards

Here is the .dex file you asked for. Thanks already.
