Utility
Notes:
1. Excitation enabled/disabled by S1. Activation polarity (open/close) determined by configuration settings (refer to
2. SPDT spring return to center-OFF position type switch (S2) for remote set point adjustment.
3. Droop enabled/disabled by S3. Activation polarity (open/close) determined by configuration settings (refer to
section).
4. Analog signal input when Auxiliary is configured for control. A_L and AU+ need to be shorted for Auxiliary 4-20 mA control.
5. Normally Open (NO)/Normally Closed (NC) contact closes/opens in a fault condition.
6. Genset battery may be connected to keep the 2500 powered on for control and monitoring. Required for shunt operation.
7. Sensing potential transformer is required if generator output voltage exceeds 600 Volts.
8. VAR/PF regulation enabled/disabled by auxiliary contact 52B. Activation polarity (open/close) determined by configuration settings (refer to
section).
9. Current transformers are optional and are necessary only if the application requires Droop, VAR, PF or Power Limiting features.
10. If the 2500 is at the end of CAN network, jumpering CL and TR provides an Internal 120 Ohm, 0.25 Watt terminating resistor for the CAN network.
Required only for CAN communication.
11. PS0 and PS1 can be used to configure presets. Closing and opening S4 and S5 configures the 2500 In one (1) of the four (4) preset configurations
(refer to
section).
12. Optional S1, S2, S3, S4, S5, 52 and “52B” contacts/relays supplied by customers. Current and voltage transformers may be installed by Regal.
13. P1 is common for both 2400 and 2500. P2 available only on the 2500.
