The PowerCommand 3100 is a generator-set controller. It is used on generator sets from Cummins/Onan, including the 1000DFHD, 620DFHA, 700DFHB and 750DFHA.
Also fitted to: Cummins/Onan PowerCommand 3100 Control.
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 1 | Green RUN lamp lights following engine startup. | Indicates all engine systems are normal. | No corrective action required. |
| 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 | ||
| 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 lamp lights | ||
| 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. |
| 1123 | Shutdown After Battle Short | ||
| 1124 | Delayed Shutdown | ||
| 1131 | Battle Short Active | ||
| 12 | The FAULT 1 or FAULT 2 fault lamp lights. Engine shuts down immediately, engine runs for several seconds and then shuts down, or engine continues to run. | The standard undesignated fault functions are programmed to shut down the set when a fault is sensed. Fault 1 is time delayed while Fault 2 is immediate. The nature of the fault is an optional selection that is determined when the set installation is designed. The undesignated fault functions may also be programmed for non-shutdown or non-time delay. | |
| 121 | Speed Signal Lost | ||
| 1244 | Engine Normal Shutdown | ||
| 13 | Fault lamp lights but no fault exists. Engine gauges show oil pressure, engine temperature, and frequency (speed) are within normal limits. | The monitor board or a sensor may be at fault. | Contact an authorized service center for service. |
