position.
NOTE: See Manual Operation. Handle and operating
lever of transfer switch should be UP.
9. Turn on the utility power supply to transfer switch,
using whatever means provided (such as a utility
main line circuit breaker). The utility power source
now powers the loads.
10. The system is now set for fully automatic operation.
Checking Automatic Operation
To check the system for proper automatic operation,
proceed as follows:
1. Verify generator is OFF.
2. Verify switch is de-energized.
3. Install front cover of the transfer switch.
4. Turn the utility power supply to the transfer switch
ON, using the utility main line circuit breaker.
5. Set the generator main circuit breaker to ON.
6. On the generator panel, select AUTO. The system
is now ready for automatic operation.
7. Turn utility power supply to the transfer switch OFF.
With the generator ready for automatic operation, the
engine should crank and start when the utility source
power is turned OFF after a ten second delay (factory
default setting). After starting, the transfer switch should
connect load circuits to the standby side after a five (5)
second delay. Let the system operate through its entire
automatic sequence of operation.
With the generator running and loads powered by
generator AC output, turn ON the utility power supply to
the transfer switch. The following should occur:
• After approximately 15 seconds, the switch should
transfer loads back to the utility power source.
• Approximately one minute after re-transfer, the
engine should shut down.
With the generator in the AUTOMATIC mode, the system
is now set for fully automatic operation.
