Anybody had this issue with a CHNC1 Hardinge lathe? When I press the green "Control on" button (Siemens 810T) it tries to power up you see the screen light up for about two seconds and you can here the main contacts make but then break instantly and I get nothing just a blank screen and I can hear the control fan running,

So I checked the main breaker relays and supply voltages from transformers etc, all good, but on further investigation I found a relay on the interface board that looks to be a part of the E-stop circuit
when I removed it the machine started up, screen lit up but I have an emergency stop 2000 showing, I checked the diagnosis page and alarm 6011 (spindle fault)

My question is would a spindle fault kill the machine dead (no start up at all)? and another odd thing when I replace the relay the machine will not start up at all, just a noise from the contactors trying to pull-in but being stopped by this relay?

Any help or ideas would be greatfully appreciated.
