Supervisory Control Wiring - Briggs & Stratton 200 Amp Automatic Transfer Switch Manuel D'installation Et D'utilisation

Supervisory Control Wiring

An air conditioner can be used with the supervisory contacts
on either terminals A-A or B-B. Terminals A-A can only be
used with supervisory control. Large loads can only be used
with contactor control on terminals B-B. Examples of each
system are described below.
1. The 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, such as an electric hot water heater.
Contacts are connected in series with the contactor
control circuit.

System Setup
You must perform the following 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 JP2 (C) installed on transfer switch
control board from '20' position to '50' position.
• Set the DPSW1 (A) and DPSW2 (B) dipswitches on the
transfer switch control board to match the kW rating of the
standby generator, as described in Setting Dipswitches.
Setting Dipswitches
Dipswitches are used to adjust control board operation based
on generator capacity. DPSW1 and DPSW2 switches are set to
correspond to total system kW rating. Dipswitch DPSW1 (A) has
units of 1,000 watts; Dipswitch DPSW2 (B) has units of
10,000 watts.
Set dipswitches with utility and generator power removed from
the transfer switch to ensure proper control system operation.
If dipswitches are set when power is present at transfer switch,
a power reset needs to be performed before the new dipswitch
settings will take effect. Power reset is when all power is removed
from the transfer switch and then reintroduced after 30 seconds.
NOTICE An FC_8 will occur on standby generator control board if
dipswitches are not properly established as noted above.
NOTICE Use extreme caution when setting dipswitches or
damage to control board will result.
• Use a pencil or small piece of plastic to set the dipswitch.
• NEVER use a screwdriver or any type of metal object to
set dipswitches.
