Schlindler 5300

Greetings

I have a schindler 5300 with a smart mrl001/002 controller, my elevator is stuck on the 3rd floor and not moving, i checked all the doors on each floor and cannot find the problem i see a red light blinking on my circuit board and it says ERR, anyone have an idea how i could fix this?

Cheers

Just to get the normal questions out of the way. Are you a elevator mechanic?

Yes

Those pics are hard to see. How did you go about checking those doors?

Err means error! But then again if you are a lift engineer you probably new that,,,,,
