Communication Status; Common Fault; User Defined Inputs And Eps Supplying Load Defaults - Kohler APM802 Installation Instructions Manual

Common Fault. Red LED flashes slowly when a single
or multiple common fault #1 occurs. Yellow LED flashes
slowly when a single or multiple common fault #2
occurs. User Programmed Inputs #1 through #5 can be
assigned to indicate a common fault and are discussed
later in this section. See also Figure 7.

Common faults are selectable on the DEC 550
controller using the respective controller menu choices.
The 550 controller offers two choices for common fault
setup.
Configure a programmable digital output on the
D
DEC 550 as a common fault and wire that into one of
the DEC 550's programmable user inputs 7, 8, or 10.
Use SiteTecht to configure the corresponding RSA
user input source 1, 2, or 3 (P41-2, -4, or -6). This is
the recommended approach since another line from
the DEC 550 to the RSA is unnecessary.
Configure a programmable digital output on the
D
DEC 550 as a common fault and wire that into the
RSA's user input source 1, 2, or 3 (P41-2, -4, or -6).

Communication Status. The RSA III is shipped from
the factory preset
communicating with a generator set controller on
Modbusr address #1 and/or ATS controller on Modbusr
address #2 with ATS connected set to False. The
generator set controller is a slave device. Additional
RSA III devices on the same network must be reset in
the field as slave devices. See Figure 6 and Figure 8.

Figure 8 Communication Status
Note: Should any communication issues occur when
adding RSA III slaves and/or transfer switches to
the system, be sure to power down the RSA III
master and then power up the RSA III master so
that the RSA III master can recognize the
changes.

Communication is okay
When communication is being
established
When the master RSA II
communication configuration does
not match the device
When the master RSA II
encounters a communication
problem with a device
When the slave RSA II does not
detect the master RSA II
When the master RSA II is set up
to communicate with the slave
RSA II and the slave RSA II does
not respond to the master RSA II
