12.
When testing under load is complete, turn OFF
electrical loads.
13.
Set the generator main circuit breaker to OFF or
OPEN.
14.
Let the engine run at no-load for 2-5 minutes.
15.
Push the generator OFF button. The engine should
shut down.
Checking Automatic Operation
To check the system for proper automatic operation,
proceed as follows:
1.
Verify that the generator is OFF.
2.
Install front cover of the transfer switch.
3.
Turn ON the utility power supply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
NOTE:
Transfer switch will transfer back to utility
position.
4.
Set the generator main circuit breaker to ON or
CLOSED.
5.
Push the generator AUTO button. The system is
now ready for automatic operation.
6.
Turn OFF the utility power supply to the transfer
switch.
With the generator ready for automatic operation, the
engine should crank and start when the utility source
power is turned OFF after a 10 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.
Installation Summary
