i need a print for a heller traction...mod#54.a...type20.3...s/n1073 it has an acceleration relay w/an"at"solid state timer &resistive grid please help
no...3phase w/L2 reading as ground @disconnect...checked supply from outside...only 2 lines +ground coming in...i have never seen 3 phase motors wired like this...my problem is potential wont pull in when a call is placed..safety relay is energized....finals &floor limits ok..i have voltage @ call stations
Unfortunately the only heller prints I have are for a m/g job, a single spped AC and a hydro. Being Westinghouse bought Heller back in the day, maybe you could try Schindler Milwaukee. Where abouts is this job located?
