| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| 111 | Internal ECM Failure | ||
| 1117 | Power Lost With Ignition On | ||
| 1121 | Fail To Disconnect | ||
| 1122 | Delayed Rated To Idle Transition — active when the generator set transitions from rated to idle if the "Rated to Idle Transition Delay" is greater than zero | "Rated to Idle Transition Delay" is greater than zero | This event/fault code can be mapped to a configurable customer output relay in order to send external notification via the relay on the base board to users so that proper action can be taken in the time given before the generator set transitions to idle; this fault can be disabled by setting the "Rated to Idle Transition Delay" to 0 seconds; to access the setup menu through the Operator Panel, go to Setup > Genset Setup > Rated to Idle Delay and set appropriately |
| 1122 | Rated To Idle Delay | ||
| 1124 | Delayed Shutdown | ||
| 1124 | Delayed Shutdown — provides advance warning of an impending generator set shutdown to loads which cannot handle sudden losses of power | Activated as a result of another non-critical shutdown fault | Troubleshoot the other non-critical shutdown fault(s) that is(are) causing the generator set to shutdown; the base board will send a signal to critical loads and will wait for the amount of time in the "Delayed Shutdown Time" parameter before shutting down the generator set; go to Setup > Genset Setup > Delayed shutdown delay from the operator panel and set appropriately |
| 1128 | Mixer Inlet Humidity Sensor: Volt Above Normal | ||
| 1129 | Mixer Inlet Humidity Sensor: Volt Below Normal | ||
| 1131 | Battle Short Active | ||
| 1131 | Battle Short Active — Battle Short has been enabled | The Battle Short parameter is Enabled; one of the configurable inputs on the base board is configured for Battle Short; the configurable input configured for Battle Short becomes Active | Disable Battle Short |
| 1131 | Battle Short Active — Warning | The control is in Battle Short mode (used to bypass several fault shutdowns therefore allowing generator set operation during emergencies) | If possible, investigate any fault codes that are being bypassed |
| 1132 | Controlled Shutdown | ||
| 1132 | Controlled Shutdown — a fault set to Shutdown with Cooldown is active and has put the generator set in a controlled shutdown | Activated by another active event/fault that is set to "Shutdown with Cooldown" | Troubleshoot the other shutdown fault(s) that are causing the generator set to shutdown; go to Setup > Genset Setup > Ctrld Shutdown Advance from the Operator Panel in order to appropriately set the Controlled Shutdown Advanced Notice Delay |
| 1139 | UFD Injector 1 Error | ||
| 1141 | UFD Injector 2 Error | ||
| 1142 | UFD Injector 3 Error | ||
| 1143 | UFD Injector 4 Error | ||
| 1144 | UFD Injector 5 Error | ||
| 1145 | UFD Injector 6 Error | ||
| 115 | Eng Crank Sensor Error | ||
| 121 | Engine Magnetic Crankshaft Speed or Position Lost One of Two Signals | ||
| 1213 | Compressor Overboost Error | ||
| 1219 | Utility Breaker Tripped | ||
| 1219 | Utility CB Tripped — the Utility CB has tripped | Overload, short circuit, or ground fault | Check the load of the application, load cables, and the ground fault relay if available; repair if necessary |
| 122 | Manifold 1 Press High | ||
| 1221 | Fail to disconnect — Utility CB have failed to open; active if the "Fail To Disconnect Enable" parameter is set to enable, event/fault code 1221 is mapped to a configurable output, and event/fault code 1453 and event/fault code 2397 are active | Event/fault code 1453 and event/fault code 2397 are active | Troubleshoot event/fault code 1453 and event/fault code 2397 to resolve this issue; to disable event/fault code 1221 go to Setup > Paralleling Setup > Power Transfer Control > Fail to Disc En on the display and set the "Fail To Disconnect Enable" parameter to Disable, then determine which configurable output is set to activate when event/fault code 1221 is active and go to Setup > Configurable I/O on the display and remove the mapping of event/fault code 1221 to that output |
| 1223 | Utility Frequency | ||
| 1224 | Genset Overvoltage | ||
| 1225 | Genset Undervoltage | ||
| 1225 | Low Genset Voltage | ||
| 1226 | Genset Frequency | ||
| 1226 | Genset Frequency Error — in Power Transfer Control (PTC) operation, active if the "Genset Frequency Sensor Enable" parameter is enabled and the genset frequency exceeds the "Genset Frequency Upper Drop-Out Threshold", or is below the "Genset Frequency Lower Drop-Out Threshold", or is Out of Range Low, for the "Genset Frequency Drop-Out Delay" | Genset frequency drop-out thresholds are incorrectly set | Drop-out thresholds are dependent on the following parameters: Genset Center Frequency, Genset Frequency Pick-Up Bandwidth, Genset Frequency Drop-Out Bandwidth; to modify the preceding parameters, on the display go to Setup > Paralleling Setup > Power Transfer Control > Center Frequency or Pick-Up BW or Drop-out BW or Drop-Out Delay and set appropriately; refer to the PTC section for setup information and instructions |
| 123 | Manifold 1 Press Low | ||
| 124 | Manifold 1 Press High | ||
| 1243 | Engine Derated | ||
| 1243 | Engine Derated — active if the engine has gone into a derate mode to protect itself from a shutdown, and if there are no other active derate events on the PCC | A derate condition has been initiated by the engine ECM | Determine the fault(s) that caused the engine to derate by checking the operator panel or using InPower or InSite to connect to the ECM; troubleshoot the event/fault(s) and resolve the issue(s) (reference the Engine Service Manual); after the issue is resolved, press the Reset button on the genset control to allow the genset to return to a normal mode of operation; if the issue is not resolved when the Reset button is pressed, the engine will stay in derated mode |
| 1244 | Engine Normal Shutdown | ||
| 1244 | Engine Normal Shutdown — a normal shutdown request has been received by the engine and no active shutdown with cooldown fault exists on the PCC (LBNG) | The generator set is going through a normal shutdown and there are no active shutdown fault(s) for at least 2 seconds | |
| 1245 | CAN Engine Shutdown — The PCC received a shutdown message from the ECM. | ECM/Engine Fault | Troubleshoot Engine Fault Codes. |
| 1245 | Engine Shutdown Fault | ||
| 1245 | Engine Shutdown Fault — engine shutdown fault has occurred in the engine ECM, and no other active shutdown faults exist on the PCC | Activated by another active shutdown fault in the ECM | Connect to the Engine ECM with InPower or Insite to determine the actual shutdown fault that is generating event/fault code 1245; then troubleshoot the shutdown fault(s) (reference the Engine Service Manual) |
| 1246 | CAN Unknown Engine Fault — The PCC received an unknown message from the ECM. | ECM/Engine Fault | Troubleshoot Engine Fault Codes. |
| 1246 | Unknown Engine Fault | ||
| 1246 | Unknown Engine Fault — an unrecognized engine fault has been received over the datalink | The generator set control received an unknown event/fault code from ECM | Connect directly to the Engine ECM with InPower or InSite to determine the actual warning or shutdown fault |

| 1247 | Unannounced Engine Shutdown | ||
| 1248 | CAN Engine Warning Fault — The PCC received an unknown message from the ECM. | ECM/Engine Fault | Troubleshoot Engine Fault Codes. |
