I need help with this one. I have recabled the system and get power but the car won't move when called. There is power to all relay switches, so does anyone have any suggestions of what i should try? I can manually push in the magnet contacts and the car moves just fine, but it won't move when any call button is pushed. I have tried replacing relays but no fix yet...any help would be appreciated.

Do you have a print? I have a 1FSOB C-6810. PM me an email will scan and send. Does it run from car buttons and not hall? Does anything on controller pick up at all? If not you need the print.

How much power have you at the Relais? Please take a Voltmeter

Did you try calling unitec with the machine number? They can usually get them from you.

When you recabled did you possibly trip a switch in the safety circuit? Check crosshead SOS switch, Governor Switch, Pit switch, and Limit switches, Some of them had a switch on Pit Door if it was a walk in pit. Not much else there except doors, gates, &fuses.
