5. Setup and Installation

Proper installation is crucial for the reliable operation of the photoelectric barrier. It is recommended that installation be performed by a qualified technician.

5.1 Safety Precautions

Ensure the power supply to the gate opener system is disconnected before beginning installation.
Wear appropriate personal protective equipment (PPE).
Adhere to all local electrical codes and regulations.

5.2 Mounting the Units

Select Location: Choose a location where the transmitter and receiver units can be mounted directly opposite each other, ensuring an unobstructed line of sight across the gate opening. The recommended mounting height is typically between 50 cm and 80 cm from the ground.
Attach Brackets: Use the provided installation material to securely fasten the metal mounting brackets to a stable surface (e.g., gate post, wall). Ensure they are level and aligned.
Mount Sensors: Attach the photoelectric barrier units (one transmitter, one receiver) to the mounted brackets. The transmitter and receiver units are typically marked or can be identified by their wiring.

5.3 Wiring

Connect Cables: Route the 2 x 10 meter connection cables from each photoelectric barrier unit to the control unit of your compatible Berner gate opener.
Terminal Connection: Connect the wires according to the wiring diagram provided in your specific Berner gate opener manual. The EL301 uses a 2-wire connection. Ensure correct polarity and secure connections.
Cable Management: Secure all cables to prevent damage and ensure a tidy installation.

5.4 Alignment and Testing

Power On: Once all connections are secure, restore power to the gate opener system.
Align Units: Carefully align the transmitter and receiver units. Most photoelectric barriers have indicator lights that illuminate when proper alignment is achieved. Adjust the units until the indicator light on the receiver (or both) shows a stable signal.
Perform Test: Activate the gate opener. While the gate is closing, interrupt the beam between the photoelectric barrier units with an object (e.g., your hand or a small box). The gate should immediately stop or reverse its movement.
Repeat Test: Perform the test multiple times at different points along the beam path to ensure consistent detection.

If the gate does not react as expected during the test, re-check alignment and wiring.

6. Operating Instructions

The Berner EL301 Photoelectric Barrier operates automatically as a safety sensor for your automated gate system. Once correctly installed and aligned, it continuously monitors the area between the transmitter and receiver units.

Normal Operation: When the beam between the units is unobstructed, the gate opener system functions normally.
Obstruction Detection: If an object (person, vehicle, animal) breaks the infrared beam while the gate is closing, the photoelectric barrier sends a signal to the gate opener control unit.
Safety Response: Upon receiving the signal, the gate opener will typically stop its movement and/or reverse direction to prevent collision or entrapment. The specific response depends on the programming of your gate opener control unit.
Test Function: The integrated test function allows for periodic verification of the barrier's functionality. Refer to Section 5.4 for details on performing a test.

The photoelectric barrier is an additional safety device and should not be relied upon as the sole safety measure. Always exercise caution when operating automated gates.

7. Maintenance

Regular maintenance ensures the longevity and reliable operation of your Berner EL301 Photoelectric Barrier.

Cleaning: Periodically clean the lenses of both the transmitter and receiver units using a soft, damp cloth. Dust, dirt, spiderwebs, or debris can obstruct the infrared beam and cause false detections or prevent proper operation. Do not use abrasive cleaners.
Alignment Check: Regularly check the alignment of the units. Strong winds, vibrations, or accidental impacts can cause misalignment. Re-align as necessary (refer to Section 5.4).
Cable Inspection: Inspect the connection cables for any signs of wear, damage, or fraying. Replace damaged cables immediately to prevent electrical hazards or system malfunction.
Functionality Test: Perform a functionality test at least once a month (refer to Section 5.4) to ensure the barrier is detecting obstructions correctly.
Obstruction Removal: Keep the area between the photoelectric barrier units clear of any permanent obstructions, such as overgrown vegetation or stored items.

8. Troubleshooting

If you experience issues with your Berner EL301 Photoelectric Barrier, consult the following troubleshooting guide.

Problem	Possible Cause	Solution
Gate does not close, or reverses immediately.	Beam obstructed. Misalignment of units. Dirty lenses. Wiring issue.	Check for and remove any obstructions between the units. Re-align the transmitter and receiver units (refer to Section 5.4). Clean the lenses of both units (refer to Section 7). Verify all wiring connections are secure and correct.
Photoelectric barrier does not detect obstructions.	Power supply issue. Severe misalignment. Damaged unit or cable. Incorrect wiring.	Check power supply to the gate opener and barrier units. Ensure units are perfectly aligned; check indicator lights. Inspect units and cables for visible damage. Contact support if damage is found. Review wiring diagram and ensure correct connections to the gate opener control unit.
Intermittent detection or false alarms.	Partial obstruction (e.g., tall grass, spiderwebs). Slight misalignment. Environmental factors (e.g., direct sunlight, heavy rain/fog).	Clear the beam path of any potential partial obstructions. Fine-tune the alignment of the units. While the IP65 rating provides protection, extreme weather can sometimes affect performance. Ensure units are securely mounted and lenses are clean.

If the problem persists after attempting these solutions, please contact Berner customer support or a qualified technician.
