SPACER 7Y4258 - Caterpillar

Verify the following before putting the engine into service:
Verify that the voltage and frequency are correct at rated engine speed
Verify that the load control devices are functioning properly and have the load isolated from the generator when not running.
If warning events are present, that is, the yellow warning lamp (2) is lit, then take corrective action if necessary.
No shutdown events are active, that is, the red shutdown lamp (3) is not lit.
For remote initiate operation, the EMCP 3 must be in AUTO mode.Engine Starting Sequence
The EMCP 3 receives an engine start signal under one of the following conditions:
The operator presses the "RUN" key.
The control is in auto and the remote initiate input (IC) becomes active.
The operator presses the "AUTO" key and a start command is sent via the RS-485 SCADA Data Link (Modbus).
Programmable cycle timer output 1 is active.
The EMCP 3 performs the following system checks before beginning the cranking sequence:
No shutdowns on any module
Engine is stopped
The EMCP 3 begins the starting sequence.
The EMCP 3 activates the pre-crank and start aid outputs, if programmed, for the configured duration.
On MUI engines, the EMCP 3 activates the starting motor relay (relay output 1) and the fuel control relay (relay output 2).
On EUI engines that do no utilize a common engine interface, the EMCP 3 activates the starting motor relay (SMR). The EMCP 3 also sends a start signal to the engine ECM via the J1939 primary data link.
On EUI engines that utilize a common engine interface, the EMCP 3 will send a start signal to the engine ECM. The start signal is sent via the J1939 data link. The ECM will be responsible for cranking the engine (4) and deactivating the starting motor relay (5).
The EMCP 3 cranks the engine for the programmed crank time or until the engine starts. If the engine does not start after the crank time has elapsed, then the starting motor relay will de-energize for the programmed rest time. After the rest time has elapsed, then the starting motor relay will start cranking again for the programmed crank time.A cycle consists of a crank time and a rest time. If the engine has not started after the programmed number of cycles, then the EMCP 3 will abort the starting process. The EMCP 3 will generate an "Engine Failure to Start Shutdown".
The EMCP 3 deactivates the starting motor relay when the engine speed reaches the set point for the crank terminate speed.Engine Stopping Sequence
The EMCP 3 will stop the engine under either of the following conditions:
The EMCP 3 will stop the engine if the operator presses the "STOP" key.
The EMCP 3 will stop the engine if the control is in auto and no longer receives any of the following:
The remote initiate input
The SCADA start signal
Programmable cycle timer output 1Note: If the control is in auto, in order for the engine to stop, the remote initiate must be inactive. And the Modbus data link must be requesting a stop. The engine will not stop if the remote
