| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 1 | Green RUN lamp lights following engine startup. | Indicates all engine systems are normal. | No corrective action required. |
| 1 | One blink indicates shutdown due to high engine coolant temperature | Coolant temperature over 230° F (110° C); the coolant thermostat switch closes at this temperature and actuates the fault circuit | Observe Coolant Temperature Gauge (option) for indication of temperature over 230° F (110° C); check coolant level in radiator after allowing engine to cool down; see that the pump belt is OK and has proper tension; check cooling system cleanliness (freedom from contaminants, rust, sludge buildup, etc.) |
| 10 | LO FUEL LAMP lights. Engine shuts down and LO OIL PRES lamp lights. | Indicates engine has run out of fuel. | Check fuel level and replenish as required. |
| 101 | IDLE MODE | ||
| 101 | IDLE MODE — 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. When the engine idle function is enabled, the control automatically sets lower oil pressure warning and shutdown trip points to reflect the lower operating speed. When the engine idle function is removed and the set reverts to normal operating speed, the control automatically resets oil pressure warning and shutdown trip points to the normal settings. |

| 101 | IDLE MODE — Warning lamp lights | ||
| 101 | IDLE MODE — Warning; 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 | EMERGENCY STOP | To reset the local/remote Emergency Stop button: Pull the button out. Move the Run/Off/Auto switch to Off. Press the Reset switch. Select Run or Auto, as required. | |
| 102 | EMERGENCY STOP — Engine shuts down and will not crank | Indicates local or remote Emergency Stop. | To reset the local Emergency Stop button: Pull the button out; Move the Run/Off/Auto switch to Off; Press the Reset switch; Select Run or Auto, as required. |
| 102 | EMERGENCY STOP — 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. |
| 102 | EMERGENCY STOP — SHUTDOWN; 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. |

| 102 | EMERGENCY STOP — Shutdown; 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. |
| 11 | LO ENG TEMP lamp lights. Set is in standby mode but is not operating. (Lamp lights when engine coolant temperature is 70° F (21° C) or lower. Since the lamp goes out after the engine warms up, there should be no cause for alarm even during initial generator set operation.) | Indicates engine coolant heater is not operating, not circulating coolant or ambient temperature too cold for heater to keep up with demand. | Check for the following conditions: a. Coolant heater not connected to power supply. Check for blown fuse or disconnected heater cord and correct as required. b. Check for low coolant level and replenish if required. Look for possible coolant leakage points and repair as required. c. Contact an authorized service center if none of the above. |

| 111 | Internal ECM error | ||
| 1117 | ECM POWER LOST — Lamp: Warning. Indicates that “Keyswitch” to the ECM was NOT removed for 30 seconds before removing battery power to the ECM (removing connectors or battery cable). | To reset, place the O/Manual/Auto switch in the O position and press E-Stop and wait 30 seconds. Remove E-Stop and press the Fault Reset button. | |
