PISTON AS 1350264 - Caterpillar

The EMCP 4 can handle all of the standard genset control functions for diesel and for gas powered gensets.Before putting the engine into service, verify the following:
The desired voltage and frequency are correct at rated engine speed
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 is lit, then take corrective action if necessary
No shutdown events are active, that is, the red shutdown lamp is not lit
For remote initiate operation, the EMCP 4 must be in AUTO modeEngine Starting Sequence
The EMCP 4 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 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 4 checks the following system items before beginning the cranking sequence:
There are no shutdowns on any module
The engine is stopped
The EMCP 4 begins the starting sequence.
The EMCP 4 activates the pre-crank and start aid outputs, if programmed, for the configured duration.
On MUI engines, the EMCP 4 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 4 activates the starting motor relay (SMR). The start signal is sent to the engine ECM. This signal is sent via the primary CAN data link or through a hardwired connection.
On EUI engines that utilize a common engine interface, the EMCP 4 will send a start signal to the Engine ECM via the CAN data link or through a hardwired connection and the ECM will be responsible for cranking the engine (step 4) and deactivating the starting motor relay (step 5).
The EMCP 4 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 4 will abort the starting process. The EMCP 4 will then generate an "Engine Failure to Start Shutdown".
The EMCP 4 deactivates the starting motor relay when the engine speed reaches the setpoint for the crank terminate speed. Engine Stopping Sequence
The EMCP 4 will stop the engine under either of the following conditions:
The operator presses the "STOP" key.
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", the remote initiate must be inactive, and the Modbus data link must be requesting a stop. If either the remote initiate
