When using a Center Tapped Delta (3-phase output is 240VL-L, but L-N is 120,208,120L1, L2,
and L3 respectively) this is the setup to select. Single phase (two lines and a neutral) of any
configuration.
12. Generator Over Freq
-Over-frequency shutdown setpoint. (Default is 65 Hz)
13. Generator Under Freq
- Under-frequency shutdown setpoint. (Default is 55 Hz)
14. Nominal Voltage
- "OK" voltage as measured at the "Nominal Voltage source". (Default is
480VAC)
15. Over-Voltage Trip
- Over voltage shutdown setpoint. (Default is 110%)
16. Under-Voltage Trip
- Under-voltage shutdown setpoint. (Default is 90%)
17. Power Factor Limit
- Maximum limit for power factor. Will shutdown generator if setpoint
is exceeded. (Default .8 set to OFF to bypass)
18. IDMT Curve
- Thermal protection for AC Alternator Off (Default) inverse; very inverse;
extremely inverse; long time inverse.
19. IDMT Pickup Current
-Current setpoints for Thermal Protection to start (Default is 300A)
20. Maximum Inst. Over-Current
- Over-current shutdown setpoint. (Default is 300A)
Instantaneous
21. PT Ratio
-In system with L-L voltages > 600V, Potential transformers must be used to
prevent voltages greater than design from being applied to the energy monitoring board.
(xxx:1) 4200V:120V = 35:1 ratio, 480:240=2 ETC. (Default is 1.00:1)
22. kVA Limit
-Limits kVA output of generator. Requires a level 5 password. (Default is 200
kVA.)
23. Over freq. Warn time
- Delay timer before system shuts down on over frequency (Default
is 3 sec)
24. Over voltage warn time
- Delay timer before system shuts down on over voltage. (Default
is 3 sec)
25. UF, UV, OC warn time
- Delay timer before system shuts down on Under Frequency,
Under Voltage or Over Current. (Default is 3 sec)
