EGCP-2 Engine Generator Control Package Manual 26086
104 Woodward
Sequence of Startup and Checking Parameters
1. Enter program Setpoints 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 of EGCP-2.
7. Check engine overview status screen for engine rpm readout confirm rpm is
correct for unit.
8. Check voltage of unit in Generator Status menu—calibrate voltage if
needed.
9. Adjust AVR voltage at AVR if needed to achieve rated generator voltage.
10. Check that voltage raise/lower switches operate properly.
a. Set voltage ramp time if needed.
11. Adjust AVR trim pot. (if equipped) for ±10% of rated voltage for ±100%
voltage bias output from EGCP-2. If this range cannot be achieved, shut
down the generator set, and select the next highest voltage bias output level
on dip switch SW-2 located on the back of the EGCP-2. Repeat steps 9
through 11 until satisfactory results are achieved.
12. Check that load raise/lower switches operate properly.
a. Set load raise/lower rates if needed.
b. Verify speed change with raise/lower load inputs.
13. Check mains voltage in synchroscope status menu (if available)—calibrate if
needed.
14. Calibrate synchronizer if possible.
15. Remove Test Input. Verify engine shuts down properly.
Loading the Generator Set
WARNING—INCREASING LOAD
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. Start unit with an Auto and Run with Load Input.
a. Unit will start and attempt to synchronize.
2. Adjust synchronizer dynamics for best control of phase matching (monitor
synchroscope status menu to see phase error.).
3. Use voltmeter to check voltage across generator breaker to assure proper
phase rotation and mains PT input polarity.
