We are now looking after an Otis 360 and after entering the shaft and installing a new Dialler, we placed the entry switch tabs back in place on the doors, we have the safety circuit but it won't return to service. Any ideas??
I am guessing it might be stuck on HAD (Hoistway Access Detection) as a result of you having entered the hoistway without following the expected sequence of opening devices, usin the stop switch, etc.
Did you try an clear the ram and do a reset? If that didn't work check for your 48volts at the controller. Maybe you guys shorted something during the replacement and didn't notice ?
