I have a York Centrifugal with an SSS14L-46A starter. I have a low voltage alarm at the control panel. I and a second Tech went through the trouble shooting guide and all conditions suggested we replace the trigger board. Today my Tech went back and replaced the trigger board and had the same condition. Chiller won't start due to low incoming voltage. It is reading around 186 or so on each phase at the control panel when it should be 460. I used Form #160.46-om3.1 to troubleshoot. Not sure what to look for next. The 460 volts are there. The dc voltage to the trigger board was 13.4 VDC or about, which according to the guide would represent 460 volts coming in. I am wondering if I am going through the procedure incorrectly or just missing something. Has anyone seen this before? Any suggestions or ideas would be greatly appreciated.
