The PowerCommand 2.3 (PCC 2300) is a generator-set controller. It is used on generator sets from Cummins/Onan, including the DFE.
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 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. | |
| 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. |

| 1245 | CAN - Engine Shutdown | ECM/Engine fault | Refer to the E-Controls service tool and the engine service manual. |
| 1246 | CAN - Unknown Engine Fault | ECM/Engine fault | Refer to the E-Controls service tool and the engine service manual. |
| 1247 | CAN - Engine Unannounced Fault | ECM/Engine fault | Refer to the E-Controls service tool and the engine service manual. |

| 1311 | Customer Input #1 — Warning/Shutdown or none for status message | The nature of the fault is an optional customer selection. Example inputs: Low Fuel Day Tank, Water In Fuel, Ground Fault, Low Starting Hydraulic Pressure, Low Starting Air Pressure, etc. | Each of the fault functions can be programmed (using service tool), as follows: Enable/disable input (Default: enable); Status, Warning or Shutdown (Default: #1—None, #2 thru #4—Warning); Active closed or open (Default: closed [ground]); Change display name using up to 19 characters (Default: #1—Customer Fault 1, #2—Ground Fault, #3—Low Fuel, #4—Rupture Basin Fault) |
| 1311 | Customer input #1 | ||
| 1311 through 1318 | Customer Defined Fault — When any one of these customer defined inputs is detected by the control, the corresponding fault message is displayed. The nature of the fault is an optional customer selection. These fault functions can be programmed to initiate a shutdown or warning as indicated by the Warning or Shutdown lamp. Note: Customer fault messages are editable. The message displayed for the code shown (1311 through 1318) is determined by the customer | ||
| 1311, 1312, 1317, and 1318 | Customer Input | If there is no actual fault, the problem may be an external wiring problem; active input (closed or open) selection is incorrect | Disconnect the signal lead from TB1 and reset the control. CUST_IN1 – TB1-4; CUST_IN2 – TB1-5; CUST_IN3 – TB1-6; CUST_IN4 – TB1-7; If the fault message clears, the external wiring has a short or open circuit, or the active input selection (closed/open) is not correct for the customer input (use the service tool to check the selection). |
| 1312 | Customer Input #2 — Warning/Shutdown or none for status message | The nature of the fault is an optional customer selection. Example inputs: Low Fuel Day Tank, Water In Fuel, Ground Fault, Low Starting Hydraulic Pressure, Low Starting Air Pressure, etc. | Each of the fault functions can be programmed (using service tool), as follows: Enable/disable input (Default: enable); Status, Warning or Shutdown (Default: #1—None, #2 thru #4—Warning); Active closed or open (Default: closed [ground]); Change display name using up to 19 characters (Default: #1—Customer Fault 1, #2—Ground Fault, #3—Low Fuel, #4—Rupture Basin Fault) |

| 1313 | Network Fault 1 | ||
| 1313-1316 | Network Fault 1 Through 4 | Indicates network input (#1-#4) is in an active state | Each of the fault functions can be programmed (using the service tool), as follows: Status, Warning, or Shutdown; Change display name, using up to 19 characters |
| 1313-1316 | Network Fault 1 thru 4 — Warning/Shutdown or none for status message | ||
