GTO Photoelectric Dual Beam Detector R4222 Owner’s Manual

Owners Manual R4222

The GTO Access Systems Photoelectric Dual Beam Detector uses dual beam and through-beam technology to reduce false detections when detecting obstructions. When the beams detect the presence of a moving
object, the detection will cause the gate(s) to stop and reverse to the fully open position. As long as the beam is obstructed the gate(s) will remain open. Not compatible with solar powered gate operators.

For use with all GTO Access Systems and Mighty Mule gate operators.

Installation Overview

Diagram illustrates correct placement of photo beams in relation to the gate.

Mounting Cautions

Be sure that the optical axis is never obstructed. (The optical axis is both the vertical and horizontal range of detection, or beam, between the transmitter and receiver)
Do not mount the detector in the following conditions:

Wall Mounting

Remove Photo Beam cover by loosening the cover holding screw, but DO NOT REMOVE THE SCREW ALL THE WAY.
Pull the wire through the wiring hole at the top of the unit, from back to front.
Remove the rubber knockout and use the screw holes to mount the unit
Mount the Photo Beam on the wall while running the wire into the wiring location in the wall.

Pole Mounting

Feed the wire through the mounting pole.
Remove the Photo Beam cover (as shown in step 1 above).
Using the Mounting Plate and Bracket secure the Photo Beam to the mounting pole.

Connecting Photo Beams to GTO Access Systems and Mighty Mule Control Boards
MPORTANT: DO NOT use Photo Beams on systems charged with solar panels.
Make sure the power switch to the opener is turned off before connecting safety device wiring to the terminal blocks. Unplugging the transformer does not turn power to the opener OFF.

Wiring Precautions

Wire with 16awg minimum (RB509)
300 ft (91.4m) max length
Be sure to capture the wire ends under the wire clamp plates.
Avoid frayed ends on wires that might produce a short circuit.
e careful not to over tighten the screws as this may strip the threads in the plastic

Terminal Strip Identification

DIP Switch Settings

Receiver DIP Switch Settings: 1&2 – Different frequency settings for multiplebeams in close proximity. Receiver and
Transmitter must have 1&2 set the same. 3&4 – For adjusting RESPONSE TIME of beam. In locations where flying debris or birds are an issue, a longer response time may be necessary. The recommend FACTORY
setting is 3&4 ON. 5 ––– For adjusting time unit remains in ALARM state. 6 ––– No function.

Transmitter DIP Switch Settings: 1&2 – Set the same as Receiver 3 ––– Beam Power – for recommended application
DIP 3 must remain on “L” low.

Beam Alignment

Adjusting Optical Axis with the Viewfinder

With the POWER connected and the RECEIVER and TRANSMITTER covers removed, make sure DIP switch 1 & 2 are set the same on the RECEIVER and TRANSMITTER. Adjust the horizontal pivot and the vertical adjustment screw. Look through the viewfinder on either side and adjust to put the opposite sensor in the middle of the cross-hairs in the view finder.
Adjust the alignment until the LED display on the receiver reads between 5 to 9 volts additionally the voltage between terminals 6 & 7 on the Receiver should be 4 VDC (±10˚).

Beam Response Time Adjustment

Adjusts the amount of time between the beam being broken and the normally open relay closing. Adjust the response time by adjusting DIP switches 3 & 4.
The factory setting is DIP 3 & 4 ON, to detect fast moving objects. This is the recommended setting for gate automation applications.

VERIFY CORRECT OPERATION

After installation, confirm correct operation by suitable walking tests. Refer to the appropriate LED indicators during the walking test and ensure the gate opener operates in the correct manner

	Condition	Indication
Transmitter	Transmitting	Power LED is ON

Receiver

| Beam Not Blocked| Power LED ON/Alarm LED OFF
Beam Blocked| Power LED ON/Alarm LED is ON

TROUBLESHOOTING

Symptom	Possible Cause	Remedy
Transmitter POWER LED does not light.	Improper voltage supplied.	Check the

power supply and wiring.
Receiver POWER LED do not light.| Improper voltage supplied.| Check the power supply and wiring.

Alarm LED does not light,

even when beams are blocked.

| 1. Beams reflect to the receiver by other objects.

2. Both beams are not blocked simultaneously.

3. Beam response time is too short.

| 1. Remove the reflecting object or change optical axis direction.

2. Block both beams.

3. Adjust Beam response time.

When beams are blocked, receiver LED lights are ON, but not alarm.| 1. Wiring is short circuited.

2. Wiring connection is not good.

| Check wiring and connection spot.
The alarm indication lamp of receiver is always on.| 1. Optical axis is not properly adjusted.

2. There are obstructions between the transmitter and the receiver.

3. The outer covers are dirty.

4. Wiring is short circuited.

| 1. Adjust the optical axis.

2. Remove the obstructions.

3. Clean with window cleaner and a soft cloth.

4. Repair wiring.

Intermittent Alarm (detection)| 1. Bad wiring.

2. Fluctuating power supply / voltage.

3. Intermittent blockage between the transmitter and the receiver.

4. The receiver or transmitter is unstable.

5. Blocked by other moving objects.

6. Beam response time incorrect for specific installation.

| 1. Check wiring.

2. Check the power supply.

3. Remove the obstruction or relocate.

4. Fix the mounting.

5. Adjust the optical axis.

6. Adjust interruption time or change installation position.
