Briggs & Stratton 100 Amp Automatic Transfer Switch - Manual (Page 7)

System Setup
You must perform the following on the control module
before operating the system:
• If generator is installed in an area regularly subjected to
temperatures below 40°F (4°C), select a 50 second
warm up time by moving jumper installed on JP2 from
‘20’ position to ‘50’ position.
• Place 2 position switch in ‘NG’ or ‘LP’ position,
whichever is appropriate for your system.
• Place 3 position switch to match KW rating of installed
generator.
Supervisory Control Wiring
1. Terminal strip on control module in transfer switch has
four connections for customer use. There are two sets
of “Normally Closed” contacts available. They will be
activated when generator power is required. These can
be used for supervisory control of large connected
loads on generator. Loads will be allowed to operate if
there is enough generator power available.
NOTE: There are two wireways provided to keep the
supervisory loads separated from each other.
2. Terminals “A-A” on control module are rated for 24 VAC
and air conditioner contactor control. Contacts are
connected in series with the air conditioner contactor
control circuit.
3. Terminals “B-B” on control module are rated for 1 Amp
125 VAC and installer supplied contactor to control a
large load. Example: electric hot water heater. Contacts
are connected in series with the contactor control
circuit.
4. Tighten all wire connections/fasteners to proper torque.
See inside transfer switch enclosure for proper torque
values.
