We have a chiller model 19XR4043321CDH which has a remote alarm dry contact that also turns on an LED on the front of the control panel. Does anyone know what conditions cause this alarm. I need to know all conditions that cause this alarm. I do not have the original documentation for this chiller and do not perform any of the work on it. The signal for this alarm relay comes from output CH44 on the PSIO module if that helps.
Any help would be great.
