Product Usage Instructions:

Installation

1. MOUNTING: Remove the covers and mount the housing using 4 screws through the corner holes.
2. WIRING: Connect power to the transmitter and receiver terminals. Wire the relay per the operator manual.
3. OPTIONAL: Install the sunshield on the receiver if needed.
4. POWER: Apply power to both transmitter and receiver.
5. SENSITIVITY: Adjust the potentiometer as needed for reliable detection.

Testing:

6. TEST OBSTRUCTION: Verify obstruction detection by placing an object between TX and RX.
7. TEST OPERATOR FUNCTIONALITY: Ensure the system stops when obstructed.

LED Indicators

• Transmitter PWR: Green LED on Power
• Receiver PWR: Green LED on Power
• Receiver OBS: Red LED on Beam blocked or not aligned

FAQ

• Q: Is the IRB-4X-2 compatible with UL-compliant gate or door operators?
• A: No, this photoeye will not work with gate or door operators that require monitored safety devices.
• Q: What is the recommended sensitivity adjustment method?
• A: Slowly reduce the RX sensitivity (counter-clockwise) until the obstruction is detected for optimal performance.

This thru beam photo-eye is an external entrapment protection device type B1, a non-contact sensor for use with automatic gates and doors. The photoeye provides a signal from the RX (receiver) to the gate or door operator that the beam is, or is not obstructed. The IRB-4X-2 operates up to 115 feet. The red alignment indicator on the RX provides status information at a glance, making set-up and alignment easy.

Cautions and Warnings

• This product is an accessory or part of a system. Install the IRB-4X-2 according to instructions from the gate or door operator manufacturer. Comply with all applicable codes and safety regulations.
• The IRB-4X-2 is not UL-compliant. This photoeye will not work with gate or door operators that require monitored safety devices.

Installation instruction

1. MOUNTING: Remove the covers. Determine your mounting height and mount housing with 4 screws (not supplied) that go through the inside of the 4 corner holes in the housing (the same holes where the plastic cover screws came out of).
2. WIRING: Pull up on and remove the green screw terminal for easy wiring. Connect 12-24 VDC/AC power to the “+ -“ TX (transmitter) terminals and “+ PWR -” RX (receiver) terminal. The power input terminals are not polarity-sensitive. Wire the relay COM and then either the NC or NO to the operator per the operator manual.
3. OPTIONAL: You may install the optional sun shield on the receiver as shown to the right in case of sun interference or cross talk.
4. POWER: Apply power to the TX and RX
5. SENSITIVITY : Adjust the sensitivity potentiometer as needed by turning clockwise to increase gain or counterclockwise to decrease. Use the minimum sensitivity setting needed to achieve reliable detection.
6. TEST OBSTRUCTION: Place an obstruction (such as your hand) between the TX and RX and the RX’s OBS LED should TURN ON when obstructed (and turn off when not obstructed and aligned). Test at different distances.
7. TEST OPERATOR FUNCTIONALITY: Power up the entire gate or door system and ensure the photo eye properly stops the system when obstructed.

TIP

If IRB-4X-2 is aligned but not detecting an obstruction, consider slowly reducing the RX sensitivity (counter-clockwise) until the obstruction is detected. This may be applicable for installations with a detection zone of less than 20 ft.

On some variable frequency drives and noisy installations, it may be necessary to connect the RX bottom right circuit board mounting hole labelled “Earth Ground” to a wire connected to earth ground. Do not connect unless necessary. The majority of the time this is not needed.

SECURE COVERS: Using the provided plastic screws secure the cover snugly (don’t overtighten them).

Troubleshooting

The signal is reflecting off another surface

| Decrease sensitivity (potentiometer counterclockwise).

Check the area for highly reflective surfaces.

Receiver’s red LED is on continuously, indicating an obstruction when one is not present| Sensitivity is too low

Transmitter does not have power

| Increase sensitivity (potentiometer clockwise).

Check the power source of the transmitter.

 | ****

Receiver does not “see” the transmitter

| Make sure the transmitter and receiver are aligned.
The receiver activates but does not transmit a signal to the operator| Faulty connection between receiver and operator control input| Verify all wires and terminal connections.
Output relay chatters constantly between open and close| Interference| 1. Wire EGND to Rx mounting hole

2.      Check for nearby sources of interference (Ex. Other photo eyes or motors)

3.      Lower sensitivity
