To start a loaded remote test
The front panel of the RSA III has an ATS TEST
pushbutton for every displayed ATS. The ATS TEST
pushbutton will only operate when the control keyswitch
is in the unlock position and the ATS is not in local-test
mode (test initiated by the ATS controller) or executing a
scheduled exercise. The ATS TEST pushbutton will not
end a scheduled exercise or a test not requested by the
RSA. The RSA III will indicate an ATS on local-test
mode (test initiated by the ATS controller) with a solid
yellow LED next to the ATS TEST pushbutton or an ATS
on remote-test mode (test initiated by the RSA) with a
solid green LED next to the ATS TEST pushbutton.
To start a remote test
Place the key-lock switch in the unlock position. Press
and hold the ATS TEST pushbutton until an
acknowledgement that the ATS is in the remote-test
mode is indicated by a solid green LED next to the ATS
TEST pushbutton. The Emergency Source Available
LED will flash rapidly while the ATS runs through the
corresponding time delays. After the transfer to the
emergency source is complete the Emergency Source
Available LED will flash slowly to indicate the ATS is in
the test mode.
To stop a remote test
Place the key-lock switch in the unlock position. Press
and hold the ATS TEST pushbutton until the Emergency
Source Available LED flashes rapidly while the ATS
runs through the corresponding time delays. After the
retransfer to the normal source is complete and the time
delays expire the Emergency Source Available LED
and ATS TEST LED will turn OFF. A loss of normal
source during a scheduled exercise or during a remote
or local test will deactivate the exercise or test.
Communications
Network communication is available via the RS-485
port. A USB port located on the front panel allows user
setup of the RSA III using a PC and SiteTecht
software.
LEDs
There are up to 33 LED indicators on the non-ATS
model, up to 4 1 LED indicators on the single ATS model,
and up to 65 LED indicators on the multiple ATS model
for status, warning, and/or shutdown. For a summary of
the LED descriptions, see Figure 6. Some items have
two LEDs:
D Communication status (green functional, red fault).
D High engine temperature (yellow warning, red
shutdown).
D Low oil pressure (yellow warning, red shutdown).
D System ready (green functional, red fault).
D (RSA III with ATS controls model only.) ATS fault
(yellow w arning/red shutdown), source (N--green/
E--red, and position (N--green/E--red).
Some functions of the LED include flashing either fast or
slow. The fast flash occurs five times per second
and
the slow flash occurs once per
second.
Alarm Silenced. Red LED slowly flashes
when alarm
horn is deactivated by Alarm Silence/Lamp Test switch.
ATS Available Source N or E (RSA III with ATS
controls model only). Green Normal and/or Red
Emergency LEDs indicate the power source availability.
ATS Fault (RSA III with ATS controls model only).
Red shutdown or Yellow warning LEDs indicate the type
of fault.
ATS Position N or E (RSA III with ATS controls
model only). Green Normal or Red Emergency LEDs
indicate the transfer switch position regardless of the
power source availability.
Aux. Fault. See Low Coolant Level/Aux. Fault. The
Aux. Fault feature is only associated with DEC 3+
controller function.
Battery Charger Fault. Yellow LED slowly flashes
when battery charger malfunctions. Requires battery
charger with alarm contact.
Battery Voltage (Hi/Lo). The DEC 3+ controller
requires battery charger with alarm contacts. See
Figure 64 and Figure 65 relating to battery charger for
additional information.
D Yellow LED flashes slowly when battery or charging
voltage drops below preset level.
D Yellow LED is steady on if battery voltage exceeds
preset level.
