4.4.3.6 Automatic Transfer Panel Kit, 50/60 Hz. This kit is used to
automatically connect a standby generator set to the load in the event of
primary power failure. The transfer panel continuously monitors the primary
source and when the voltage or frequency decreases to a preset value, it will
start the standby generator set, and transfer the load when the generator set
frequency and voltage meet minimum requirements. The transfer will be
break-before-make, thus there will be a momentary loss of voltage to the load.
When primary power returns and meets minimum requirements for a predetermined
time, the transfer panel will transfer the load back to the primary power
source. After transfer of the load back to the primary power source, the
standby generator set will run at no load for five minutes, shut down, and
automatically cycle the generator set controls for standby operation. The
transfer panel also permits starting of the standby generator set for a test run
without disconnecting the load from the primary power source. If during the
test run primary power should fail, the load will automatically be transferred
to the standby generator set. The transfer panel is fully enclosed and may be
wall or base mounted. It is designed for operation in ambient temperatures from
+125° F to -65° F and provides power for the electric winterization kits which
are required when using this kit to assure starting of the set within 20
seconds. Batteries of the standby generator set are maintained in a fully
charged condition by the internal transfer panel battery charger.
