Voltage Regulator settings:
Droop - set for 2 to 5 %
In a multiple generator system, set
droop the same on all regulators
Terminals A and B will
provide a 10% per volt range
If using a Marathon 2000EC,
the VAR/PF control must be
disabled in the AVR or the EGCP-2.
AVR - software configurable or
jumpering terminals 52J and 52K.
EGCP-2 - software configurable
Adjustment Procedure
1. Start the generator with the EGCP-2
NOT connected and set for rated
voltage.
2. Connect the EGCP-2 as shown.
3. Start Generator
4. Adjust the Volts Bias Offset for
rated voltage.
5. Press ENTER to save this value
6. Close the Voltage Raise discrete
input (4) and verify the EGCP2 can
move the generator voltage in the
increase direction.
7. Close the Voltage Lower discrete
input (5) to verify the EGCP-2 can drive
the generator voltage in the decrease
direction.
