8. Configure the DEC 3+ controller for the
remote serial annunciator.
Note: After setting DIP switches to the generator
set application, be sure to power down and then
power up the controller; either disconnect the
battery and then reconnect the battery of the
generator set, use the prime power switch (if
equipped), or remove and then replace the F2
controller fuse. The controller will NOT
acknowledge the DIP switch change until after
generator set controller is powered up .
8.1 Set the controller Modbus
r
address to #1 by
placing DIP switches 6, 7, and 8 to the open
position. See Figure 50.

8.2 The DEC 3+ controller baud rate is fixed at
19200. No change is required.
8.3 If the RSA III is used with a DEC 3+ controller and
it required installing a communication module
board, refer to TT-1285 Program Loader
Software instructions for downloading firmware
version 1.23 or higher with red controller
board or 2.03 or higher with blue controller
board.
8.4 Replace the controller cover and hardware.
9. Restore the generator set to service.
9.1 Place the generator set master switch in the
OFF/RESET position (OFF mode on the
Decision-Maker
e
8000 or Out-of-Service mode
on the APM802 controller).
9.2 Reconnect the generator set engine starting
battery, negative (--) lead last.
9.3 Reconnect power to the battery charger, if
equipped.
9.4 Energize the RSA III(s).
9.5 Place the generator set in AUTO (select AUT
mode on the Decision--Maker
e
8000) for startup
by remote transfer switch or remote start/stop
switch.
9.6 Reset alarm horns as needed.
10. Configure the APM802 controllers for the
remote serial annunciator.
The APM802 is factory configured to work with the
RSA III. The APM802 controller defaults to a 19200
baud rate and to an address of #1. Refer to Figure 51 for
the default APM802 controller settings.
Note: The RS-485 address on the APM802 must match
the address on the RSA III master.
