EGCP-2 Engine Generator Control Package

Sequence of Start-up and Checking Parameters
1. Enter program set points in all menus.
2. Check discrete inputs in I/O status menu.
3. Set crank repeats to 0.
4. Set synchronizer mode to check.
5. Set load control mode to normal.
6. Start engine using test switch (discrete input 2) of EGCP-2.
7. Check Engine Status screen for engine rpm readout confirm rpm is correct
for unit.
8. Check voltage of unit in Generator Status screen—calibrate voltage if
needed.
9. Adjust AVR voltage at AVR if needed to achieve rated generator voltage.
10. Follow AVR connection and setup procedure in Appendix C.
11. Check that voltage raise/lower switches (discrete inputs 4 and 5) operate
properly.
Set voltage ramp time if needed.
12. Check that load raise/lower switches (discrete inputs 6 and 7) operate
properly.
Set load raise/lower rates if needed.
Verify speed change with raise/lower load inputs.
13. Check mains voltage in synchroscope status menu (if available)—calibrate if
needed.
14. Remove Test Input. Verify engine shuts down properly.
Loading the Generator Set
Operation of the engine/generator set with incorrect CT and PT
phasing could cause serious injury or damage to equipment. If the
load on the unit rises rapidly when the generator or mains breaker is
closed, immediately open the breaker and shut the unit down. Check
the phasing of the PT and CTs. DO NOT permit the unit to continue to
pick up load or operate the system without correcting this condition.
Mains Parallel Units
Follow these steps if you are configuring a Mains Parallel Master Unit, or a Mains
Parallel Slave unit, which will operate as a redundant master. Redundant master
units must have the Mains CB Aux hardwired into them. All other wiring to the
Master and Redundant Master Units must be identical for proper operation of the
redundant units in the event of a loss of master.
1. Set load/unload ramp times to at least 60 seconds.
2. Set base load level to 30% of rated load.
3. Start unit with an Auto and Run with Load Input.
a. Unit will start and attempt to synchronize.
4. Adjust synchronizer dynamics for best control of phase matching (monitor
synchroscope status menu to see phase error.).
5. Use voltmeter to check voltage across generator breaker to assure proper
phase rotation and mains PT input polarity.
6. Shut down the unit by removing the Auto and Run with Load Inputs.
7. Set synchronizer to run mode.
8. Start unit with an Auto and Run with Load Input.
