Have a TAC 20. 2 stop, twin post single stage jacks,4500 lbs capacity, 2 sp side opening doors, LD-03 door operator. No emergency lowering UPS. It has a pressure switch. Does not have a UIT and we do not have access to IMS.

Issue: Every morning we find the car in the pit. It has all run LEDs high and electronic starter ready to go. Will not level up or take a hall call. Upon reset it levels up and runs fine all day.
We replaced all 24VDC Finder relays,verified selector,tape and magnets all OK.
Any ideas on what else to check???
