SPACER 3086542 - Caterpillar

The normal mode monitors the generator set and the normal mode controls the generator set. The GSC controls the engine through information that is received from panel switches, controls, and engine sensors. The GSC performs the following functions in normal mode.
Starting the engine
Monitoring of important generator set conditions
Showing important generator set conditions to the operator
Fault Detection
Engine StoppingThe operator can identify the normal mode by observing the display area. When the GSC is in the normal mode all shutdown indicators are OFF. The fault alarm indicator is OFF and "SERV" is NOT SHOWING on the upper display. When the GSC is in normal mode, the engine is able to start or run.Note: The optional Customer Communication Module (CCM) can remotely control certain generator set functions. This remote control can only occur when the ECS is in the AUTO position. See Systems Operation, "Customer Communication Module (CCM)" for more information.Engine Starting Sequence
The GSC will receive an engine start signal. The signal will be one of three.
The operator turns the ECS to the MANUAL START position.
The ECS is in the AUTO position and the remote initiate contacts (IC) close.
The ECS is in the AUTO position and a start command is sent by the optional Customer Communication Module (CCM).
The GSC checks the system before the cranking sequence is begun. The GSC checks that no system faults are present. The GSC checks that all previous shutdown faults have been reset. Note that shutdown faults are removed by turning the ECS to OFF/RESET. The GSC also checks that the engine is not already running.
The GSC activates the starting motor relay (SMR) and the run relay (RR).
The GSC activates the fuel control relay (FCR) for ETR fuel systems or the GSC leaves the fuel control relay (FCR) deactivated for ETS fuel systems.
The GSC cycle cranks the engine until the cycle crank time reaches the setpoint (P17) for total cycle crank time or until the engine starts. The factory default of setpoint P17 is 10 seconds crank time and 10 seconds rest.
While the starting motor is cranking, the GSC shows the status of the relays on the relay status indicators of the lower display.
ETR fuel systems:K4 (SMR), K5 (RR), K7 (FCR)
ETS fuel systems: K4 (SMR), K5 (RR)
The GSC deactivates the starting motor relay (SMR) and the GSC activates the crank termination relay (CTR) when the engine speed reaches the setpoint P11 crank terminate speed. The factory default of setpoint P11 is 400 rpm.
The GSC activates the electronic governor relay (EGR) when the oil pressure reaches the setpoint P14 for low oil pressure at idle speed. The factory default of setpoint P14 is 70 kPa (10 psi). The EGR signals the electronic governor (EG) to accelerate the engine to rated speed.Note: The optional Customer Communication Module (CCM) can remotely activate the EGR when the low oil pressure setpoint is exceeded. The optional Customer Communication Module (CCM) can remotely deactivate the EGR when the low oil pressure setpoint is exceeded.
The GSC shows AC voltage, current, and frequency for
