fault is critical. When a shutdown fault occurs, the GSC automatically activates shutdown mode until the shutdown fault is corrected. The GSC shuts down the engine when the GSC is in shutdown mode. The GSC prevents starting of the engine and the GSC alerts the operator. The GSC alerts the operator and the GSC identifies the shutdown fault by FLASHING the corresponding shutdown indicator. The name of the shutdown indicator identifies the shutdown fault. Shutdown Indicators
Low oil pressure
Emergency stop
High water temperature
Engine overspeed
Low coolant level
Engine overcrank
Fault shutdownIf the fault shutdown indicator is the only indicator FLASHING, additional information is available. A fault code is shown on the upper display which more precisely identifies the cause of the shutdown fault. See Systems Operation, "Fault Description" for more information. Shutdown Mode Sequence
A shutdown fault occurs and the GSC detects the shutdown fault.
To shut off the fuel, the GSC deactivates the fuel control relay (FCR) for ETR systems or the GSC activates the FCR for ETS systems
In order to prevent the engine from starting, the GSC deactivates the run relay (RR), and the GSC deactivates the starting motor relay (SMR).
In order to remove the generator load, the GSC activates the genset fault relay (GFR). This activates the optional circuit breaker shunt trip coil. Note: The spare output may also be programmed to activate when a shutdown occurs. This output can drive a relay in order to open the circuit breaker, or the output can open a transfer switch. See Systems Operation, "Spare Input/Output Programming OP6".
The GSC activates the air shutoff relay (ASR) for 15 seconds during an emergency stop fault, engine overspeed fault, or speed sensor fault (CID 190).
When engine speed reached 0 rpm, the GSC deactivates the crank termination relay (CTR). The electronic governor relay (EGR) is deactivated when the engine oil pressure reaches the setpoint (P14) for low oil pressure shutdown at the idle speed 70 kPa (10 psi).
For ETS fuel systems, a timer within the GSC is set to keep the fuel control relay (FCR) active for 70 seconds after engine speed decreases to 40 rpm and oil pressure decreases to 80 kPa (12 psi).
If engine speed does not decrease at least 100 rpm within five seconds, the GSC activates the air shutoff relay (ASR) for 15 seconds. Note: The ASR would already be activated for an emergency stop fault, engine overspeed fault, or speed sensor fault.
The GSC FLASHES the corresponding shutdown indicator. If the fault shutdown indicator is FLASHING, a fault code is shown on the upper display. See Systems Operation, "Fault Description".
If the fault shutdown indicator is the only indicator FLASHING, additional information is available. A fault code is shown on the upper display that more precisely identifies the cause of the shutdown fault. See the Systems Operation, "Fault Description".
The lower display continues to show the engine data.
The relay status indicators show.
K2 (GFR)
K6 (ASR) will show for 15 seconds for an emergency stop fault, engine overspeed fault, overspeed sensor fault. K6 (ASR) will also show if engine speed does not decrease at least 100 rpm.
K7 (FCR) - (ETS fuel systems) for 70 seconds after engine speed decreases to 40 rpm and oil pressure decreases to 80 kPa (12 psi). (K7 is not shown for ETR fuel systems.)Engine Start Sequence (After Shutdown)
Correct the shutdown fault. See the Testing And Adjusting, "Fault Identification".
Reset the GSC by turning the ECS to "OFF/RESET". If no shutdown fault is active, the GSC returns to normal mode and the engine is able to start.
