NOTES:
1. Excitation enabled when switch (S3) is open and disabled when switch is closed.
2. SPDT spring return to center-OFF position type switch (S1) for remote set point adjust.
3. Droop enabled when switch (S2) is open and disabled when switch is closed.
4. Normally-open contact closes in a fault condition.
5. Analog signal input when Auxiliary is configured for control or metering.
6. Should be shorted when Auxiliary is configured for 4-20 mA control or metering.
7. Sensing potential transformer is required if generator output voltage exceeds 600 Volts.
8. VAR/PF regulation enabled when auxiliary contact (52B) is open and disabled when 52B is
closed.
9. Phase B current transformer (CT-B) secondary may be connected to either quick-connect
terminals CT1 and CT2 or J2-2 and J2-11.
10. 120 ohm 0.25 watt resistor required if DVR is a terminal device on CAN backbone.
11. S1, S2, S3, “52” contactor and transfomers supplied by others.
