Operation

To select automatic transfer operation, do the following:
1A. For models 071018 & 071019, set disconnect switch
that sends utility power to transfer switch to "On"
position. This switch is probably located in the main
breaker panel.
1B. For models 071020 & 071021, set utility breaker in
transfer switch "On" position.
2. Set generator main circuit breaker to its "On" position.
3. Install 15 Amp fuse in generator control panel.
4A. If generator is equipped with a system ON/OFF switch,
set switch to "On" position.
4B. If generator is equipped with a AUTO/OFF/MANUAL
switch, set switch to "AUTO" position.
The system will now be in automatic operation mode.
When the generator is providing power to the transfer
switch, the control module is constantly monitoring
generator power. If the air conditioner is called to run, and
there is sufficient generator power available, the control
module will close contacts "A-A" to air conditioner contactor.
Contacts "B-B" will open before contacts A-A close. If loads
are too great for generator, contacts A-A and/or B-B will
open. When air conditioning is not needed, A-A will open. If
enough power is available, B-B will close.

Testing the Automatic Transfer Switch

Turn the disconnect switch feeding the transfer switch
contactor to the "Off" position. The Automatic Sequence of
the system will follow. To go back to utility power, turn the
disconnect to the "On" position.
