INSTALLATION
To prevent possible product damage and incorrect operation:
• NEVER scratch or paint the optical sensors.
• DO NOT drill ANY additional holes into the Monitored Light Curtain.
• Correctly connect and align the Monitored Light Curtain transmitter
and receiver.
• DO NOT bend or twist the Monitored Light Curtain.
INSTALL ONE SET OF MONITORED LIGHT CURTAINS AS STANDALONE PRIMARY ENTRAPMENT PROTECTION
The mounting brackets must be securely fastened to a solid surface such as a wall framing. If installing the mounting brackets in masonry construction, add
a piece of wood at each location to avoid drilling extra holes in the masonry. NOTE: If the Monitored Light Curtain is installed with coil cord, the coil cord
needs to be secured so it will not interrupt the light beams.
1. Fasten the mounting brackets loosely to both Monitored Light Curtain with the screws provided.
2. Measure a maximum of 6 inches above the floor. Mark this location. The lowest optical sensor of the Monitored Light Curtain must be installed at or below
this point. In this application, in order to assure that the lowest optical sensor is mounted no higher than 6" above the ground, the light curtain wires must
be oriented at the top of the light curtain in this application.
3. Hold the Monitored Light Curtain up to the desired mounting location with the cable end pointing upward. Secure the bottom mounting bracket to the
mounting surface.
4. Make sure the Monitored Light Curtain is level and secure the upper mounting bracket to the mounting surface.
5. Tighten the screws to secure the Monitored Light Curtain to the mounting bracket.
6. Secure the other Monitored Light Curtain to the opposite side of the door following steps 2 - 5, making sure they are aligned.
7. Run wires to the operator.
8. Twist like colored wires together, brown to brown and blue to blue.
NOTE: In this application, in
order for the lowest optical
sensor to be no higher
than 6" above the floor, the
wiring of the Monitored Light
Curtain must be facing in the
upward direction. If installed
with the wires facing down,
the lowest optical sensor will
be much higher than 6" above
the ground; it will be approx.
9-10" above the ground.
INSTALL TWO SETS OF MONITORED LIGHT CURTAINS
Installing two sets of Monitored Light Curtains on the same
door is recommended when taller portions of vehicles and
equipment must be protected. Applicable with HCT, LOGIC 5.0,
and HPH1 Operators.
1. Install the first set of Monitored Light Curtain on the door as
described in the Install One Set of Monitored Light Curtain
section.
2. Install the second set of Monitored Light Curtain above the
first set. The black and white wires are wired in parallel and
the blue and brown wires are wired in parallel.
3. Position the Transmitters and Receivers as shown in the
image below to prevent cross-talk. In this application, the
upper Light Curtain may be mounted with wiring oriented up
or down.
NOTE: When a 2nd Monitored Entrapment Protection device
is used with the HCT Operator, the 2nd device must be wired
to the existing HCT Expansion Board. When a 2nd Monitored
Entrapment Protection device is used with a LOGIC 5.0 Operator,
the 2nd device must be wired using the CPS3CARD (plug-in option
card.) When a 2nd Monitored Entrapment Protection device is used
with HPH1, no additional hardware is required.

• Oil may damage the Monitored Light Curtain cable so contamination
MUST be avoided at ALL times.
• DO NOT mount the Monitored Light Curtain where sunlight or other
external infrared light sources will shine directly into the optical sensors
of the Monitored Light Curtain receiver. If necessary, switch the
mounting side of the Monitored Light Curtain transmitter and receiver.
