Hello everyone I am new and I am asking for help.
I have 1997 GEA Grasso ammonia screw compressor and I can not cancel the high pressure discharge alarm.Every time I try, the screen says "alarm canceled" but the alarm comes back again and again.

If it's danfoss, screw the top of and reset is under the cover.

If it's any other brand, there should be a reset button somewhere under the cover, if not it's auto reset and either the pressure is still to high or the pressostat is broken!
