Generators
After engine start, placing a starter/generator switch in the GEN
position energizes the generator circuit relay and extinguishes
the GEN light. Energization of the relay completes a circuit to
energize the respective DC regulator power and positive sense
relay, Freon compressor relay, and a circuit for the voltage reg-
ulator equalizer.
On S/N 35-083 and subsequent, 36-021 and subsequent,
and earlier aircraft with AMK 76-6A, placing a starter/genera-
tor switch in the GEN position energizes a circuit to energize
the DC regulator power and positive sense relay, parallel 28V
DC circuit, regulator power, and the Freon compressor.
When both generators come on-line, the voltage regulator
equalizer circuit energizes. Both voltage regulators then work
together to regulate their generator’s output. Each adjusts its
generator field until a balanced condition exists between the
generators. If both generator ammeters are within 25A, both
generators are operating in parallel.
If generator output exceeds 31 ± 0.5V, the voltage regulator
trips the generator off-line through the overvoltage relay and
the respective GEN light illuminates. After a generator overvolt-
age, holding then releasing the generator RESET switch resets
the generator circuit. The generator switch must be in the GEN
position for the reset to work.
The generator also goes off-line if an undervoltage condition
occurs and the respective GEN light illuminates.
