8.18 Remote Serial Annunciator
(RSA 1000)
Adapted from Instruction TT-1377 4/08.
The following information summarizes the setup items
when troubleshooting the remote serial annunciator
(RSA). Refer to the RSA installation instructions for
operation and function. See Figure 8-36 for RSA front
panel illustration. See Section 8.19, Communication
Module and Gauge Driver Circuit Board.

Figure 8-36 Remote Serial Annunciator (RSA)
8.18.1 DIP Switches
The RSA will function as master or slave by changing the
DIP switch position on the RSA board. See Figure 8-37
for RSA circuit board features.
The RSA annunciates faults using LEDs and an alarm
horn. Press the Alarm Silence/Lamp Test switch to test
the RSA indicator LEDs and horn. If the horn is activated
by a fault condition, press the Alarm Silence/Lamp Test
switch to quiet the alarm during servicing. The horn will
reactivate upon additional tests.
Set the SW1 DIP switches on the RSA master and
subsequent RSA slave (if used). See Figure 8-38. RSA
connected to controller MUST be assigned as the RSA
master.

When SW1-1 is OFF, the generator set controller
activates the EPS Supplying Load LED. When SW1-1 is
ON (local), transfer switch activates LED.
Note: When SW1-4 is in the slave position, DIP
switches SW1-1, SW1-2, and SW1-3 are not
functional as the RSA master annunciates the
RSA slaves.
