Greetings Bojan

I will try, but the door closes on a reset then goes down to the pit, when i call up the lift, the door opens, i press the floor below, it shows CO for code, i press the floor number plus code, the door
starts to close then stops halfway then reopens, lift not moving, remaining on floor.
I looked at the power on the photo cell, it was measured correctly, tested blocking the photocell and it worked. Dip 8 would have worked if the lift only showed error CO without pressing the floor
numbers. This is a very strange problem.

Cheers
