DI3201 DI3201-A-V001 Digital input module

The EGCP-2 Control is designed to automatically control the cranking functions of the engine generator set. In order to safely control engine cranking the EGCP-2 uses the following set points, as found in the Engine Control tuning menu of the software: Preglow Time Crank Delay Crank Time Crank Repeats Crank Cutout The description of the above items is found in the Tuning Screens section of this manual in the Configuration Menu list.Starting Sequence: Upon receiving a start command the following events occur: 

1. The Preglow Output Energizes for the given preglow time delay, and remains energized through the crank cycle. 

2. After the preglow time expires, the Fuel Solenoid output energizes. 

3. 200 ms after the Fuel Solenoid output energizes, the Crank output energizes.

At this point, the engine

 should be cranking at a certain rpm, and receiving fuel. Typically a start would occur in these conditions. To check if a start does occur, the EGCP-2 monitors the magnetic pickup from the engine. If the magnetic pickup input indicates that the engine is operating above the Crank Cutout speed, the EGCP-2 will remove the Crank and Preglow outputs, leaving the fuel solenoid energized. The engine state in the control overview menu changes from “OFF” to “RUN”. If for some reason the engine does not reach the crank cutout rpm level, the EGCP-2 will crank the engine for the Crank Time. If the engine fails to rise above the crank cutout level in this time, the EGCP-2 will remove the Crank output signal, wait for the Crank Delay, and if allowed by the number of Crank Repeats, will crank the engine again (RETRY). This sequence will continue until the number of crank repeats is depleted, or until the engine speed rises above the crank cutout rpm setting, whichever comes first. If the number of crank repeats is depleted, the EGCP-2 will activate the Crank Fail Alarm Output based on this Alarm set point’s configuration.

The preglow output

 may stay energized between crank attempts if the preglow time is greater than the sum of the Crank Time and Crank Delay timers. IMPORTANT Set Crank Repeats to zero when starting the engine for the first time with the EGCP-2. This will prevent starter and ring gear damage to the engine if the MPU input to the control should be faulty. Monitor Engine Overview Status menu on the first start and confirm the rpm readout during cranking. After a successful start is made, the crank repeats may be set to the appropriate value for the application.
