Manual 26086 EGCP-2 Engine Generator Control Package
Woodward 33
5. Calculate CT Ratio, Voltage Input is WYE
KVA * 1000 / Voltage Ref * 3
• Answer: If value is ≤ CT Ratio = Unit OK
6. Calculate Voltage = Voltage Ref / PT Ratio
• Answer: If Calculated Voltage ≤ 500 = Unit OK
7. Calculate Rated KVA, Voltage Input is DELTA
• Answer: Calculated KVA ≤ (Voltage Ref * 1.73) * CT Ratio = Unit OK
8. Calculated Rated KVA, Voltage Input is WYE
• Answer: Calculated KVA ≤ (Voltage Ref * 3) * CT Ratio = Unit OK
9. Rated KW ≤ Rated KVA
10. Rated KVAR ≤ Rated KVA
If the EGCP-2 is not providing an engine start signal:
• Check for pound signs (#) signs and/or asterisks (*).
• Any item opened in the Configuration menu only, does not pertain to any
of the other menus, no start process will be performed until this item is
closed by pressing the ENTER or ESC key.
Example—If viewing the “Rated KW” on the display, no start signal will be
provided.
Network Address (1 to 8)
• Unique Address for Each Unit in the System.
• Maximum of 8 units on network.
Network Priority (1 to 8)
• Unique Priority for Each Unit in the System.
• Lowest Active Priority is considered Master.
• Maximum of 8 units on network.
• Sequencing effective from lowest to highest priority.
• When priority is reduced below 1, the value will change to “Set All”. If the
commit key is pressed when this value is on the display, the display will
change to represent all units in auto on the network, and their priority. The
network priority of any unit can be changed by using the left/right and
up/down keys on the control. Once changes are made, the changes are
committed by pressing the commit key twice. Pressing the escape key
from within the set all setting will restore the previous priorities.
Number of Poles (numeric)
• Determines Speed/Frequency Relationship.
• Used for Speed/Frequency Mismatch Alarm/Shutdown.
Number of Teeth (numeric)
• Determines rpm Scaling.
• Engine Speed Readouts/Alarms.
System Frequency (50/60 Hz)
• Used as a basis for generator waveform analysis.
• Defines typical operating frequency of generator.
Rated Speed (numeric)
• Synchronous Speed Of Generator Set.
• Used in Speed Calculation to determine “sample” period for MPU input.
