Hello everyone.
I am having trouble with a Citizen B12-6. We have had a part off detection switch get smashed up inside and this has caused the mc to have these stated alarms.

1000 Emergency Button Pushed
1001 Power Circuit DC off
1002 Coolant Pump Thermal Actuation

I believe this is causing a problem with the 24V DC supply. If anyone has any ideas of reset buttons ect?
As shown in photos the white box is not powered up?

Thank you for any help in advance.

Hi

All these alarms are caused by the machine 24v dc shorted to earth from your pat off probe
Disconnect the part off probe from the relay board and all will be well
