PC2 Voltage Readings
Voltage Feedback: 240 volts AC with respect to RC1-2
Voltage Feedback: 240 volts AC with respect to RC1-1
Pulse Width Modulation (PWM) Signal: 0 to +15 volts DC at no load; voltage increases with genera-
tor load
Shutdown Signal: +12 volts DC when shutdown is latched; 0 volts DC when shutdown is not latched
Circuit common
Revolving field (rotor): +25 volts DC at no load with respect to power board PC1 RC31-4; +75 volts
DC at full load with respect to power board PC1 RC31-4
+ 12 volts DC
Enable Line: +12 volts DC when generator is enabled (On); 0 volts DC when generator is not enabled
(Off)
Revolving field (rotor): +25 volts DC at no load with respect to power board PC1 RC31-4; +75 volts
DC at full load with respect to power board PC1 RC31-4
Be sure plugs are secure before
testing. See Section 6-5 for specific
values during testing.
