| Symptom | Cause | Remedy |
|---|---|---|
| Control does not power up when the Run/Off/Auto switch is set to Run or the Self Test switch is pressed. | There is no DC power to the control. | A. Check for battery disconnected, discharged, or improperly connected. b. Contact an authorized service center. |
| Engine starts from generator control panel but will not start automatically or from a remote panel. | Check the control wiring between the remote switch and the PCC. | Contact an authorized service center. |
| Engine stops cranking. | Discharged or defective battery. | Recharge or replace the battery. Clean the battery cable terminals and tighten all connections. Check engine DC alternator. Replace engine DC alternator if normal batery charging voltage (12 to 14 VDC) is not obtained. |
| No AC output voltage. | Contact an authorized service center. | |
| Non-Automatic lamp flashes. | Indicates Run/Off/Auto switch is not in the Auto position. This will prevent automatic starting if an automatic transfer switch is used. Move the Run/Off/Auto switch to the Auto position for automatic operation. | |
| PCC will light a yellow Warning lamp or a red Shut-down lamp and display a message on the digital display panel. | Abnormal conditions such as low oil pressure and high coolant temperature occur. | If the genset is stopped for this reason, the operator can restart the genset after making adjustments or corrections. |
| Shutdown lamp lights. | Check coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. | |
| Warning lamp lights. | Indicates battery voltage is below 24 VDC. a. Discharged or defective battery. Check the battery charger fuse. Recharge or replace the battery. b.
