Controls; Operation - Briggs & Stratton 200 AMP AUTOMATIC TRANSFER SWITCH Installation And Operator's Manual

The "On" position for the dipswitches is the switch number
ON THE CONTROL BOARD, not on the switch. For example,
on a 27,000 watt generator, set DPSW2 dipswitch 20 to "On"
position. Set DPSW1 dipswitch 7 to "On" position. 20,000
plus 7000 equals 27,000 watts.
System Test
With the generator system switch in AUTO, turn the service
disconnect feeding the transfer switch contactor to the OFF
position. After a few minutes the generator will start and the
transfer switch will transfer to generator power.
To return to utility power, turn the service disconnect feeding
the transfer switch to the ON position.

Controls

Other than a Manual Override lever, there are no operator
controls because this is an automatic transfer switch. The
manual override is to be used only by licensed professionals.

Operation

To select automatic transfer operation, do the following:
1. Set service disconnect switch that sends utility power
to transfer switch contactor to "On" position.
2. Install 15 Amp fuse in generator's control panel.
3. Set generator's circuit breaker to "On" position.
4. Set generator's system 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 controller
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 the 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.
Enclosure Door

and pull down on the door.

While in this position, push door upwards. This will cause
spring-load door lock to engage and latch door in place.
NOTE: Enclosure door MUST be closed and latched at all
times except when system is being serviced.
