The “sanity checks” are:
1.
Calculate MPU frequency
= Rated Speed * Number of Teeth / System
Frequency
Answer:
500
calculated MPU frequency
8000 = Unit OK
2.
Calculate System Frequency
= Rated Speed * Number of Poles / 120
Answer: should equal System Frequency’s configured value, 50 or 60
Hertz
3.
Calculate Power Factor
= Rated kW / Rated kVA
Answer:
0.7
Calculated Power Factor
1 = Unit OK
4.
Calculate CT Ratio, Voltage Input is DELTA, =
kVA * 1000 / Voltage Ref * 1.73
Answer: If value is
CT Ratio = Unit OK
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 = Unit OK
If the EGCP-2 is not providing an engine start signal:
Check for pound signs (#) signs and/or asterisks (*).
If any item is open in the Configuration menu (does not pertain to any of
the other menu) no start operation will be performed until this item is
closed by pressing the ENTER or ESC key.
Example—If viewing “Rated KW” in the Configuration menu, no start signal will
be provided.
Network Address
Range: 1 to 8
Unique Address for Each Unit in the System.
Maximum of 8 units on network.
Network Priority
Range: 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
Enter 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 priorities.
Using the left/right and up/down keys on the control, one can change the
network priority of any unit. Once changes are made, the changes are
committed by pressing the Enter key twice. Pressing the Escape key from
within the Set All parameter will restore the previous priorities.
