I been working on a mv40 w/ yasnac mx3 control circa 1989.
Here is the issue.
When booting up there is multiple errors , It comes down to the 24NC circuit. If booted while holding emergency release and atc button on the side-it boots up with 000 spindle alarm only. Otherwise I get no 24v throught the nc24 circuit. I have switched power supplys to no avail (cpu10nb). I get no output voltage from CN11 at the power supply during normal startup.
Could this be a Thermal relay as the fan on the spindle as it was froze? and replaced. Please help!

Again, did you check the bridge rectifier coming off the 30VAC transformer?

Checked Rec 1 and 2, tested OK. I can get the 24nc power and that activates the servos and oil cooler. However I get a 000 servo alarm and no charge light on the inverter- I pulled the chassis and checked the the trysistors, etc. OK-
There is a rec marked C1 on the prints, I don't know if that is the same as rec1. I can't locate any others?
