5. About 15 seconds after the generator (alternate
source) acceptable light comes on, the automatic
transfer switch should transfer the load from the utility
to the generator. At that time the Transfer Switch on
generator light should come on.
6. The generator will stay connected to the load for
about 5 minutes at which time the transfer switch will
transfer the load back to the utility. At the time it
transfers back to utility the Transfer Switch on Utility
light should come on and the Transfer Switch on
generator light should go out. To bypass this five
minute time delay you can press and release the
Push to Test button again at any time.
7. After the load retransfers to the utility the generator
will continue to run for about 1 minute (without a load)
and then shut down. The Generator acceptable light
will go off indicating the generator set has shut down.
Once you are finished testing the transfer switch, this
completes your installation and unit testing. ALWAYS
leave the system in automatic mode unless servicing the
unit. For automatic operation, keep the generator set
mode switch in the “AUTOMATIC” position.
