4. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
4.1 മ ing ണ്ടിംഗ് സ്ഥാനം
The photo eye and its reflector must be mounted on opposite sides of the gate opening, ensuring an unobstructed line of sight between them. Mount both components securely to a stable surface, such as a gate post or wall, at a height that will detect typical obstructions (e.g., vehicles, people). The maximum detection range is 30 feet (9.1 meters).
4.2 Mounting the Sensor and Reflector
- Using the provided mounting bracket and hardware, securely attach the photo eye sensor to one side of the gate opening.
- Attach the reflector to the opposite side of the gate opening. Ensure the reflector is positioned directly in line with the sensor.
- The sensor and reflector should be mounted at the same height and parallel to each other for optimal performance.

5. വയറിംഗ് നിർദ്ദേശങ്ങൾ
പ്രധാനപ്പെട്ടത്: Ensure power to the gate operator is disconnected before performing any wiring.
The RETROAB 60-2728 photo eye operates on 12VDC. Refer to your specific gate operator's manual for exact wiring terminal locations. Typically, the photo eye will connect to the operator's safety input terminals.
- ബന്ധിപ്പിക്കുക പോസിറ്റീവ് (+) wire from the photo eye to the 12VDC (+) terminal on the gate operator control board.
- ബന്ധിപ്പിക്കുക നെഗറ്റീവ് (-) wire from the photo eye to the Common (-) terminal on the gate operator control board.
- ബന്ധിപ്പിക്കുക സിഗ്നൽ wire from the photo eye to the designated സുരക്ഷാ ഇൻപുട്ട് terminal on the gate operator control board.
This photo eye is compatible with LiftMaster RSL12V, RSW12V, CSL24V, CSW24V, and LA500 operators. Consult the operator's manual for specific wiring diagrams.
6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
The RETROAB 60-2728 is a retro-reflective photo eye. This means the sensor unit emits an infrared beam that travels to a reflector and bounces back to the sensor. When an object breaks this beam, the sensor detects the interruption and signals the gate operator to stop or reverse, preventing potential impact.
6.1 Alignment Indicator
The photo eye typically features an LED indicator. When the sensor is properly aligned with the reflector and the beam is unobstructed, this LED will illuminate (e.g., solid green). If the beam is broken or misaligned, the LED will change state (e.g., turn off or flash), indicating an issue.
6.2 ഫങ്ഷണൽ ടെസ്റ്റ്
After installation and wiring, perform the following test:
- ഗേറ്റ് ഓപ്പറേറ്ററിലേക്ക് പവർ പ്രയോഗിക്കുക.
- Observe the photo eye's alignment indicator LED. It should be illuminated, indicating proper alignment.
- Initiate a gate closing cycle.
- While the gate is closing, carefully place an object (e.g., a cardboard box) in the path of the photo eye beam.
- The gate should immediately stop or reverse its direction. If it does not, disconnect power and refer to the "Troubleshooting" section.
- Remove the object and allow the gate to complete its cycle.
Repeat this test periodically to ensure continued safe operation.
7. പരിപാലനം
Regular maintenance ensures the longevity and reliable operation of your photo eye.
- വൃത്തിയാക്കൽ: Periodically clean the lens of the photo eye sensor and the surface of the reflector with a soft, damp cloth. Dust, dirt, spiderwebs, or debris can obstruct the beam and cause false detections or prevent proper operation.
- പരിശോധന: Visually inspect the sensor, reflector, and wiring for any signs of damage, corrosion, or loose connections. Ensure mounting hardware remains secure.
- പ്രവർത്തനക്ഷമത പരിശോധന: Perform the functional test described in Section 6.2 at least once a month, or more frequently in harsh environments.
8. പ്രശ്നപരിഹാരം
If the photo eye is not functioning correctly, refer to the following common issues and solutions:
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| Gate does not close, or reverses immediately. | Beam obstructed or misaligned. | Check for obstructions. Clean sensor lens and reflector. Re-align sensor and reflector until alignment LED is solid. |
| Photo eye LED is off. | No power to the photo eye or faulty wiring. | Verify 12VDC power supply. Check all wiring connections for security and correct polarity. |
| Gate closes even with an obstruction. | Photo eye not wired correctly to operator, or photo eye is faulty. | Review wiring instructions (Section 5) and your gate operator's manual. Perform functional test (Section 6.2). If problem persists, the photo eye may need replacement. |
| ഇടയ്ക്കിടെയുള്ള പ്രവർത്തനം. | Loose wiring, environmental interference, or partial obstruction. | Check all wiring. Ensure sensor and reflector are clean. Verify stable mounting. Consider potential sources of interference (e.g., direct sunlight, reflective surfaces). |
