Product Overview
The IRB-4X photoeye system does not have a focusing lens and the generous 24osensing angle makes it one
of the easiest to align. The use of the hoods is recommended to prevent distortion from rain on the lens area.

WARNING … Not to be used for Personnel Protection
Never use product as sensing devices for personnel
protection. Doing so could cause serious injury or death.
These sensors do NOT include the self-checking redundant circuitry
necessary to allow their use in personnel safety applications. A sensor failure or
malfunction can cause either an energized or de-energized sensor output
condition. UL 325 Non-compliant

IRB-4X Transmitter connections (figure 1)
1. Connect power (12 –24V AC/DC) to
Power input terminals (no polarity) LED2
Power LED will glow green when powered.
IRB-4X Receiver connections (figure 2)
Terminal output connections from left to right are:
Normally closed, Common, Normally open, Power, Power
1. Connect power (12 –24V AC/DC to Power input terminals (no polarity)
2. Connect the Common to the operator control terminal per manufacturer
3. Connect either the Normally open or Normally Closed as needed to the
Control input terminal specified by the operator manufacturer.
4. The Power LED will glow green when powered.
5. Adjust sensitivity potentiometer as needed by turning counter clockwise
to increase gain. (range is 3 to 115 feet). (see arrow)
6. The detect Led will glow red when an obstruction occurs.
7. On some variable frequency drives and noisy installations, it may be
necessary to connect the bottom right mounting hole labeled
“Earth Ground” to a wire connected to earth ground.
* Do not connect unless necessary
Use minimum gain setting needed to achieve reliable detection.

1. Mount to operator manufacturer and local ordinance requirements.
2. Remove grey front cover by removing (4) plastic retaining screws
3. Drill (4) mounting holes in surface of IRB-4X mounting location.
4. Place gold Aluminum hood or Powder coat Steel hood around
IRB-4X unit to be mounted, place mounting screws through IRB-
4X box and hood and attach to surface.
5. Make all connections to the transmitter and receiver.
6. Adjust receiver as described above to correct gain needed.
7. Replace front covers on the transmitter and receiver units.
8. Installation is complete.
Installation
TROUBLE SHOOTING GUIDE
Symptom
Possible Cause
Possible Solution
Holds gate open
No power on transmitter or receiver
Check power LEDs and power source
Transmitter not working
Install new transmitter
Receiver not working
Install new receiver
Sensitivity set too low
Adjust sensitivity
Does not activate gate
Bad connection or broken wires
Check wires and connections
Relay contacts burned or stuck
Replace receiver
Interference from local source
See step 7 under Operational settings
Not connected to correct input terminals
Check operator manual for terminals
Sunlight “blinding” the receiver eye
Change position of receiver to a little
higher and tilt forward to shield the
sensor from the direct sunlight
Chattering
Interference or stray bounced signal
See step 7 under Operational settings
and see if any reflective surfaces could
be sending signal into the receiver sensor
