MO Saftey Switch Problem ok the blanket safety bar is not working, too micro switch off and it should have disabled it, didnt happen, that did nothing, went into the electrical box and the contacter relay switch is out when it should be in, i pushed the relay and the error went away, the only problem is that it wont stay pushed in, press is MOVP-H
ft walton - if you have a meter, simply check the A1 and A2 terminals, if you read 110 volts across (or 220 volts if so marked) the coil is bad.
ft walton - What market was this machine originally run in (US,Europe, Canada, etc...)? I just want to make sure we're understanding each other. If you are measuring across the A1 and A2 coil lugs (not A1 to ground and A2 to ground), and you get control voltage, that would be 110V or 220V depending on what country the press was originally built to run in, then the magnet would be energized and contactor pulled in. Make sure you are actually at the coil lugs, they would be the ones way in the back of the contactor/relay.
Not an electrician just basic troubleshooting. If the micro switch is normally open, by disconnecting it should be fine (the function of the circuit). If the switch is normally closed, you will need to jump the leads. Be careful to make sure you have the correct information before doing this.
