TP-6946 3/16 37Section 4 Communication and Accessory Connections
Use 14-24 AWG cable to connect to inputs and outputs.
See Figure 4-14.
LEDs on the module circuit board light to indicate that
each input or output is active.
Note: Each I/O module must have a unique address.
Use the address DIP switches on the I/O module to
assign a unique (different) address to each module a s
shown in Figure 4-15. Assign addresses in order from 1
to 4. An LED for each DIP switch lights to indicate that
the switch is closed.
The alarm module’s fixed address is 5. The battery
module’s fixed address is 6.
See the controller operation manual for instructions to
assign functions to each input and output. Inputs and
outputs can also be assigned using a personal
computer with Kohlerr SiteTecht software or over
Modbus. See TP-6701, SiteTech Operation Manual, or
TP-6113, Modbus Protocol Manual.

4.3.3 External Battery Supply Module
(EBSM or BOB)
The external battery supply module kit allows
connection to the generator set engine start battery(ies)
or other batteries to provide 12 VDC power to the ATS
controller. The EBSM is also referred to as the battery
option board (BOB).
The EBSM/BOB kit is required for the following
applications:
D Systems using extended engine start time
delays. The EBSM/BOB provides power to the ATS
controller during extended time delays longer than 15
seconds, when neither the Normal nor the
Emergency source is available.
D Installations with frequent utility power outages.
The EBSM/BOB provides power to the ATS controller
when neither source is available, preserving the
controller’s backup battery.
D Three-source systems. Three-source systems use
two transfer switches and two standby power sources
in addition to the preferred power source. The
EBSM/BOB provides power to the second ATS
controller when the preferred source (connected to
ATS1) is supplying the load. See Section 3.1 for
instructions to set up a three-source system.
The external battery supply module kit includes one
external battery supply circuit board and the circuit
board mounting components. See Figure 4-16.
