All diagnostic steps

STEP 1

Measure the 24V DC input voltage supplied to the control unit and ensure the voltage is not dropping below the required level (+20V or more).

STEP 2

Check the '24VDCIN' LED on the control unit. If it is not lit, inspect for a failure of the DC24V input or if the fuse near the DCIN connector is disconnected.

STEP 3

Check the 'DCOUT' LED on the control unit. If it is not lit, inspect for a short circuit of the DC5V output on the CG71, ENC, or FAN connector.

STEP 4

If all external connections, voltages, and fuses are normal but the DCOUT or LCDON LEDs are still not lit, there is a failure of the internal voltage output in the control unit. Replace the control unit.
