VOLTAGE REGULATION
The generator output voltage is regulated by the voltage regulator circuitry. By using an integrated
circuit comparator amplifier with a regulated reference voltage, and difference between the
reference voltage and the generator voltage is amplified and supplied to the comparator circuit,
which controls the shunt field excitation of the generator. Prior to installation, the voltage regulator
is adjusted under NO load condition to maintain 26.5+-.2 volts DC generator output voltage. After
installation, the generator over voltage control should be adjusted to 27.5 VDC generator output
voltage at the bus with normal systems turned on.
VOLTAGE REGULATOR REMOVAL
Gain access to the voltage regulator by removing R.H. aft cowl skin. If removal is necessary,
proceed as follows:
A.
Verify that the battery switch is OFF, that the external power is disconnected, and that the
batteries are disconnected.
B.
Disconnect the retaining clips from the voltage regulator and remove voltage regulator from
voltage regulator base.
VOLTAGE REGULATOR INSTALLATION
