    EC25 problem

I've even seen shims under some before now but persivere .. you will get it
    I have te same symtoms on my EC25 . I have measured the switch and it closes and openes the contacts properly. My problem may be in the other end of the cable. Where is the other end connected?

    Problem probably solved.

    Thanks for answering. I will start a new thread on my next posting. However I'll post the last message here. The problem with the start of my EC25 is probably solved. I checked all the relays and also cleaned the contactors. There is a special bistable relay in the control circuit with the keypad safety circuit. The relay was OK, but the socket had very low pressure on the contacts. After cleaning the socket everything worked well. I will later put some solider on the relay contacts to make them thicker.

    Happy that the problem has been solved. Those contacs tend to loosen as connector material (brass) gets fragile due to vibration.
