SEAL 4464610 - Caterpillar

mode is used in order to monitor the generator set. Normal mode is also used to control the generator set. The GSC+P controls the engine according to the information which is received from the operator and the information that is received from the engine sensors. The GSC+P performs the following functions in normal mode:
Start Engine command
Monitoring of the important GSC+P conditions
Showing the important GSC+P conditions to the operator
Fault detection
Engine stoppingThe operator can identify normal mode by observing the display area. When the GSC+P is in 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+P is in normal mode, the engine is able to start or the engine is able to run.Note: The optional Customer Communication Module (CCM) can remotely control certain generator set functions. This remote control can only occur when the Engine Control Switch (ECS) is in the AUTO position. Refer to Systems Operation, "System Communication Module (Customer)" for more information.Engine Starting Sequence
The GSC+P receives an engine start signal. The signal will be one of two.
The operator turns the ECS to the Manual Start position.
The ECS is in the AUTO position and the customer issues a remote start command.
The GSC+P checks the system before beginning the starting sequence. The GSC+P checks that no system faults are present. The GSC+P checks that all previous shutdown faults have been reset. The GSC+P also checks that the engine is not already running. Note: Shutdown faults are removed by turning the ECS to OFF/RESETposition.
The GSC+P begins the starting sequence.
The GSC+P activates the RR and the Electronic Governor Relay (EGR). The EGR relay sends a run command to the Engine Control Module (ECM) located on the engine.
The engine cranks until the cycle crank time reaches the setpoint for total crank time or until the engine starts. The factory default of the setpoint is 10 seconds of crank time and 10 seconds of rest time. The GSC+P setpoints that are related to cranking (P017 and P018), do not affect on the cranking cycle. In order to adjust the cranking time, adjust the cranking parameters in the ECM.
While the starting motor is cranking, the GSC+P shows the status of the relays on the relay status indicators of the lower display.
ETR fuel systems: K4 (SMR), K5 (RR), K7 (FCR)
On EUI engines, K1 (EGR) is also shown.
The engines' ECM deactivates the starting motor relay when the engine speed has reached the crank terminate speed. Factory default for crank terminate is 400 RPM. The GSC+P activates the Crank Termination Relay (CTR) when the engine speed reaches the setpoint P011 for crank terminate speed. The factory default of setpoint P011 is 400 rpm.Note: The GSC+P crank terminate setpoint does not impact the actual crank terminate speed.
The GSC+P shows the following information.
Information for one or more phases on the upper display
Information for power meter on the lower display
Information for the engine system on the lower display
For ETR fuel system, the relay status of
