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 unique address.
Use the address DIP switches on the I/O module to
assign a unique (different) address to each module as
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 Kohler

External Battery Supply Module
(EBSM)
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 external battery supply module kit is
required for the following applications:
D
Systems using extended engine start time
delays.
The EBSM 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 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
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.
