Emitter
Cordset
Receiver Cordset
EZ-SCREEN Type 2
emitters
have an 8-pin cordset, but only three conductors are
required:
•
Brown = +24 V dc
•
Blue = 0 V dc
•
Green/Yellow = GND
Do not connect any wires to the machine control circuits (that is, OSSD outputs)
at this
time.
For the
initial
checkout, only the following EZ-SCREEN Type 2 receiver conductors
should be connected:
•
Brown = +24 V dc
•
Blue = 0 V dc
•
Green/Yellow = GND
Additionally,
connect the external reset switch, if used, or test signal contact to
the Reset/Test wire (violet) and to 24 V dc.
Note: The reset switch must be a normally closed switch that is held open for approximately 1/4 second, then closed to
accomplish the reset. The switch must be capable of switching 10 to 30 V dc at 30 mA.
The other wires are for an
optional
hookup that allows for parallel
connection
(color-for-color) to the receiver cable. This
optional
hookup provides for sensor interchangeability (or swapability) that facilitates installing either sensor at either QD
connection.
Besides
providing similar cabling, this wiring scheme is advantageous during
installation,
wiring, and
troubleshooting.
4.2.1 Sensor Interchangeability
The
figures
and table below illustrate a wiring
option
that provides sensor interchangeability (or swapability)—the ability to install
either sensor at either QD
connection.
The
resulting
installation
provides the ability to swap the
emitter
and receiver
position.
This wiring
option
provides advantages during
installation,
wiring, and
troubleshooting.
To use this
option,
connect all
emitter
wires in parallel (color-for-color) to the receiver cable via individual wires or the CSB..
splitter
cordset (can be used with only
emitters
and receivers with similar connectors, such as a pair with 8-pin quick disconnects or a pair with
5-pin quick disconnects.).
Model CSB..
splitter
cordsets and DEE2R.. double-ended cordsets allow easy
interconnection
between an EZ-SCREEN Type 2 receiver
and
emitter,
providing a single homerun cordset.
