The PCL-001 is a generator-set controller. It is used on generator sets from Cummins/Onan, including the 36 DGBC, 40 DGBC, 48 DGCA and 51 DGCA.
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 101 | Engine continues to operate at reduced RPM. | Indicates that the engine is operating in idle mode. When the set is operating in the RUN mode, grounding the engine idle input causes generator build-up to be inhibited and the engine to be governed at 800 RPM. When ground is removed from this input, the set returns to normal speed and voltage. | |
| 102 | Engine shuts down and will not crank. | Indicates local or remote Emergency Stop. | To reset the local Emergency Stop button: Pull the button out or turn the switch clockwise (button with arrow) and allow it to pop out. Move the Run/Off/Auto switch to Off. Press the Reset switch. Select Run or Auto, as required. |

| 151 | HIGH COOLANT TEMP ALARM | A. Check jacket water coolant level and replenish if low. Look for coolant leakage and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check fan belt and repair if necessary. d. Reset control and restart after locating and correcting problem. | |
| 152 | LOW COOLANT TEMP | A. Coolant heater not connected to power supply. Check for blown fuse or disconnected heater cord and correct as required. b. Check for low jacket water coolant level and replenish if required. Look for possible coolant leakage points and repair as required. | |
| 197 | COOLANT LEVEL WARNING | A. Check jacket water coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. b. Reset control and restart after locating and correcting problem. | |
| 212 | Shutdown lamp lights. | Indicates engine has overheated (coolant temperature has risen above the shutdown trip point: 223° F – standby / 215° F – primary) or the coolant level is low. Allow engine to cool down completely before proceeding with the following checks: | A. Check coolant level and replenish if low. Look for coolant leakage and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check fan belt and repair or tighten if necessary. d. Reset control and restart after locating and correcting problem. Contact an authorized service center if none of the above. |
| 213 | The light will display the fault codes (active or inactive) in succession, starting with the most recent. Up to 32 (unacknowledged) fault codes can be stored in control panel memory. | ||
