6-7. Control Board PC2 Test Point Values
PC2 Voltage Readings
a) Tolerance −
±
10% unless
specified
b) Condition − no load; generator
running at 3000 (50 Hz) or 3600
rpm (60 Hz)
c) Reference − to circuit common
(RC1-5) unless noted
Receptacle Pin Value
RC1 1 Voltage Feedback: 240 volts AC with respect to RC1-2
2 Voltage Feedback: 240 volts AC with respect to RC1-1
3 Pulse Width Modulation (PWM) Signal: 0 to +15 volts DC at no load; voltage increases with genera-
tor load
4 Shutdown Signal: +12 volts DC when shutdown is latched; 0 volts DC when shutdown is not latched
5 Circuit common
6 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
7 + 12 volts DC
8 Enable Line: +12 volts DC when generator is enabled (On); 0 volts DC when generator is not enabled
(Off)
9 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
