Model SRC-8
Addressable 8-Output Relay Module
OPERATION
The Model SRC-8 module from Siemens
Industry, Inc., used with the SXL-EX System is
an 8-Output Programmable Relay Module that
provides eight Form C relays. Terminal Block 9
(See Figure 1 below) provides a connection to
TB3 on the Main Board for a 24V regulated and
filtered power supply. Terminal blocks 1-8
provide the eight Form C relays.
If the green LED (labeled
DS1)
on the right-
hand side of the module is on, it indicates that
the module is active.
The SRC-8 causes a trouble on the display
panel when any of the following three conditions
occurs:
1.
There is a short on the data line.
2.
No SRC-8 module is connected to the
System, though there
is
an address for the
module in the System.
3.
An SRC-8 module is connected to the
system, but there is no address for it in the
System.
INSTALLATION
Remove all System power before
installation, first battery and then AC.
(To power up, connect the AC first
and then the battery.)
In a New SXL-EX System
(Refer to Figure 2):
Install the SRC-8 in the upper right-hand
portion of the EN-SX enclosure by following the
