System Setup - Briggs & Stratton 100 Installation Manual

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.
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.
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.
10
The "On" position for the dipswitches is the switch number ON
THE TRANSFER SWITCH CONTROL BOARD, not on the switch. For
example, for an 18,000 watt generator, set DPSW2 dipswitch 10 to
"On" position. Set DPSW1 dipswitch 8 to "On" position. 10,000 plus
8000 equals 18,000 watts. Set only one switch to "On" position
on DPSW1 and DPSW2.
Refer to following chart for proper switch selection(s).

NOTICE Air density is less at high altitudes, resulting in less
available engine power. Specifically, engine power will decrease 3.5%
for each 1,000 feet (300 meters) above sea level and 1% for each 10°
F (5.6°C) above 77°F (25°C). Generators located in these conditions
must have the transfer switch programmed appropriately for this
power decrease.
