4.1.3 Inputs and Outputs
(Connector P9)
A remote test switch and an external exerciser can be
connected to the black 6-pin connector P9 on the
accessory board. See Figure 4-2 and Figure 4-3. P9
also includes a generator set supplying load output
connection.
Note: The ATS main logic board has a similar green
6-pin connector. Do not interchange the black
and green mating connectors.
Connections. Connect input and output leads to
connector P9. Refer to the label on the enclosure cover
or Figure 4-3 for the connections. Use #12--24 AWG
wire and tighten the connections to 0.5 Nm (4.4 in. lb.).
Remote Test Input. Connect a remote switch to this
input for remote starting and stopping of a loaded test.
DIP switch 3 affects the operation of this switch. See
Section 4.1.5, Accessory Board DIP Switches, and
Section 4.2, External Alarm Module.
Generator Set Suppling Load Output. This output
provides a closed contact to indicate that the generator
set is supplying the load when the transfer switch is in
the Emergency position and the GEN source is
available. Connect to customer-supplied equipment.
Remote Exercise Input. Connect the optional
Programmable Exerciser to this input to allow
scheduling of additional loaded or unloaded generator
set exercise runs. DIP switch 2 affects the operation of
this input. See Section 4.1.5, Accessory Board DIP
Switches.
See Section 4.3 and TT-1403, Programmable Exerciser
Instructions, for more information about the
programmable exerciser.
Note: Always replace the cover before energizing the
transfer switch controls.

4.1.4 Time Delay Adjustment Switches
The 10-position rotary switches allow adjustment of the
time delays shown in Figure 4-4. Use a small
screwdriver or other small tool to increase or decrease
the time delays within the range shown in the table. The
rotary switch positions range from 1 to 10, with
position 10 labeled 0 (zero).
The factory settings are the same as the controller time
delays without the optional accessory board.
