Frequently Asked Questions - LS2060 ABUS

How to correctly align the transmitter and receiver?

Use the built-in alignment laser for coarse alignment: turn it on the transmitter, point the beam at the receiver, then adjust until both LEDs on the receiver turn off. For fine adjustment, measure the voltage at the receiver’s test points and adjust horizontally then vertically to obtain the highest value (ideally between 3.4 and 5 V).

What is the maximum outdoor range of the LS2060?

The maximum outdoor detection range is 60 meters. Indoors, it reaches 120 meters.

How to adjust the response time (passage time)?

The response time is adjusted using the potentiometer on the receiver. It is adjustable from 50 ms to 700 ms by rotation. A longer time prevents false triggers (e.g., leaves, animals).

What to do if the alarm LED (red) stays on permanently?

This indicates a misalignment or an obstacle between the transmitter and receiver. Check that nothing is blocking the beam (bushes, wires, etc.), clean the front cover with a soft cloth, and realign the devices following the adjustment procedure.

What supply voltage is required?

The power supply must be a DC voltage of 10 to 30 V (non-polarized). Total current consumption (transmitter + receiver) is approximately 69 mA.

How to mount the detector on a pole?

Use a pole with a section of 38 to 45 mm. Attach the assembly brackets to the pole with M4x20 screws, then screw the mounting plates onto the bases using M4x10 screws. Finally, fix the plates to the brackets. Then follow the wall mounting steps for wiring.

What to do if no LED lights up on the transmitter or receiver?

Check the wiring and the presence of voltage at the terminals. Ensure the power supply is correct (10-30 V DC). If the problem persists, the cable or the device may be defective.

How to test the proper functioning of the alarm?

After installation and adjustment, simultaneously interrupt the two infrared beams (by passing your hand in front of the lenses). The alarm LED (red) should light up and the relay should switch (NO/NC contact). Take into account the adjusted response time.

What are the outdoor operating conditions?

The device is weatherproof (IP55) and operates from -25°C to +55°C. However, avoid direct exposure to salt water or splashes. In case of heavy fog, the range may be reduced.

What accessories are supplied with the LS2060?

The delivery includes a transmitter (Tx) and a receiver (Rx) with their front covers, housing screws, mounting plates, assembly brackets, and screws (M4x10 and M4x20). Detachable bases are also integrated.

6. Installation

6.1 Important notes

• Remove all obstacles (plants, washing lines and other objects) between the transmitter and the receiver.
• Avoid direct light or sunshine on the transmitter and receiver.
• Avoid installation where dirt and water can fall directly on the transmitter and receiver.
  Install the transmitter and receiver on a stable, vibration-free surface.
• Avoid positioning so that the beams reflect on surfaces or objects.
• Reduce the recommended range if there is a high probability of mist or similar unfavourable weather conditions.

6.2 Position of transmitter and receiver

The recommended installation height for transmitter and receiver is between 0.70m and 1m . Both components can be adjusted horizontally (+/-90^) and vertically (+/-15^) . This permits flexible installation in the most varied physical conditions (see examples A, B and C).

6.3 Detection range

When installing the photoelectric beams, note the detection range (L) and radiation range (X) of the transmitter.

Model	Detection range L (Outdoors)	Spread of beams X
LS2030	30 m	0.9 m
LS2060	60 m	1.8 m
LS2080	80 m	2.4 m
LS2120	120 m	3.6 m

6.4 Wall mounting

1. Remove the front cover of the transmitter and receiver by undoing the housing screw.
2. Loosen the base-plates by undoing the fixing screw and remove it
3. You now have two ways of fixing the connection cable to the rear side. a.) Guide the connection cable through the cable guide on the base-plate. b.) Guide the connection cable through the cable guide of the detector. To do this, remove the predetermined breaking point from the rear of the detector to guide the connection cable through.

1. Now break out the opening for the cable guides on the rear of the transmitter and receiver and connect the cables to the correct connectors.
2. Screw the base-plates to the desired installation locations.
3. Screw the transmitter and receiver to the nase-plates.
4. After connecting the cables to the connectors, go to the "Putting into operation" section.

6.5 Pole mounting

1. Use a pole with a diameter of 38-45 mm.
2. Remove the screwed base-plates of the transmitter and receiver.
3. Screw 2 screws M4x20 into the screw-threads of the mounting brackets.

4. Fix the mounting brackets to the masts.

5. Screw the mounting plate with 3 screws M4x10 tightly to the base-plates of the transmitter and receiver.

6. Fix the mounting plates to the mounting brackets.
7. Repeat steps 3-7 of "Wall mounting".

7. Putting into operation

Before aligning the photoelectric beam, connect the power supply.

You can also connect up the alarm and tamper lines after alignment.

7.1 Rough alignment with laser and LED

Important:

Never look directly into the laser beam! The laser used has a power of <= 5 mW at a wavelength of 650 nm and belongs to Class 3a (classification according to DIN VDI 0837).

1. Switch on the laser switch of the transmitter.
2. Align the transmitter horizontally and vertically so that the laser beam points to the centre of the receiver. Alignment is optimal when both LEDs of the receiver stop lighting.
3. To check: repeat steps 1 and 2 with the laser on the receiver.

The LED on the receiver gives you a first indication of the strength of the received signal.

Alarm LED (red) and signal LED (yellow)	Signal strength
Both LEDs OFF	Optimal
One LED ON	Adjust
Both LEDs ON	Realign

7.2 Fine adjustment by voltage measurement

1. When the transmitter and the receiver are firmly mounted at the installation location, you can make the fine adjustment of the photoelectric beam by measuring the voltage level.
2. Switch your measuring device to the setting "DC" and select the lowest voltage range (0-10 V DC).

3. Measure the voltage on the receiver and compare the value with the table below.

4. Now adjust the horizontal angle of the receiver by hand until the measuring device shows the highest value.

5. Turn the adjusting screw to adjust the vertical angle of the receiver until the measuring device shows the highest value.
6. Compare the voltage with the values below.
7. After achieving a good alignment quality, do not realign the transmitter or receiver again.

Voltage level	Quality of alignment
5 V – 3.4 V	Optimal
3.4 V – 1.15 V	Good
1.15 V – 1.0 V	Sufficient
< 1.0 V	Readjust

7.3 Adjusting the response time

By turning the potentiometer on the receiver, you can change the response time (default 300 ms) of both light beans until an alarm is detected. If the actual response time is shorter than the set response time, no alarm is triggered.

7.4 Putting into operation

1. Now close the transmitter and receiver with the front covers.
2. Carry out a walk test. Take the response time you set into consideration.
3. If required, readjust the Receiver and repeat the walk test.

8. Troubleshooting

Fault	Possible reasons	Remedy
Power LED on transmitter (Tx) or receiver (Rx) does not light	Incorrectly connected or no power	Check the voltage supply at the connectors
Alarm LED (Rx) does not light when the photoelectric beam is interrupted	- No power - Tx and Rx incorrectly aligned - The photoelectric beams were not interrupted simultaneously	- Check the voltage supply - Clean the front cover - Check the wiring
Photoelectric beams are boken and the alarm LED (Rx) lights, but no alarm is triggered	- Wrong or missing connection of alarm contacts - Relay defect due to over-voltage	Check the connections of the alarm contacts
Alarm LED (Rx) lights permanently	- Tx and Rx incorrectly aligned - Photoelectric beam is interrupted - Front cover is dirty or covered in ice	- Realign Tx and Rx - Remove all obstacles between Tx and Rx - Clean the front cover
False triggering of photoelectric beam by leaves, animals, etc.	-Tx and Rx badly aligned- Response tune set too low-Unfavourable environmental influences at installation location	-Realign Tx and Rx- Change the installation location
