Do you have a terminal block, down at the bottom of the control, with terminals marked C1, C2, C3, etc? I think thats DC to ground, and each terminal is farther down the line, of all the series of n/c contacts in the safety circuit. But I haven't worked on that stuff for over 20 years, so you better order a print form Unitec, if you can.
Is the car at floor level? Or on the limits?
Any motor or loop overload dashpots tripped? Is the J-switch in? (three-phase monitor, with visible contacts)
