Our technicians measured the wetting voltage across terminal block inputs and found only 12 VDC instead of the required 70 VDC loop power. Further trace troubleshooting revealed that external power connector J13M1 from the EPSM module had backed out slightly during routine panel maintenance. Reseating connector J13M1 restored the full 70 VDC wetting supply, lighting the board's channel LEDs and restoring real-time feedback to the M1 controller.
