General Instructions and Precautions

This light curtain can be used in industrial, commercial and garage doors and gates, as
described in EN 12453, when it is used as device type E according to clause 5.5.1.
Even though the sensor has a high degree of immunity to ambient light sources, it is
recommended to avoid direct exposure to sunlight, and interference from flashlights or other
infrared light sources, such as other photo sensors.
If the front cover of the sensor becomes contaminated, it has to be cleaned with a slightly
damp cloth. Do not use organic solvents or detergents. If the light curtain is very contaminated,
the output may go into safe state and de-energize even after the cleaning, due to safety
reasons.
Ensure that the sensor is mounted, so that it is mechanically stable during operation.
Severe rain and snow may be detected due to the high sensitivity of the light curtain.

Mounting & Alignment
Mounting & Alignment
Mount the transmitter and receiver sensors facing each other. Make sure the distance
1
between the sensors does not exceed the specified sensing range of the system.
Align the sensors by turning, either the transmitter or receiver sensor, horizontally and
vertically until the output is:
2
- Deactivated when no object is present. (Dark operated)
- Activated when no object is present. (Light operated)
Fasten the transmitter and receiver sensors securely.
3
Avoid acute angles on cable close to sensor.

Transmitter power adjustment

The transmitting power can be adjusted externally via the wires of the transmitter sensor.
Adjust using a resistor (e.g. a potentiometer) of 200 ohm to 10k ohm or a voltage source of 1-
4 V dc connected respectively between control and – supply (ground) wires. Adjustment of the
transmitter power may be required in applications where objects to be detected are small or
translucent. Proceed with the following steps:
1 Select target object with the smallest dimension and most translucent surface.
Place target object between transmitter and receiver sensors. If the output is activated,
2
adjustment is not required. If the output is not activated proceed to step 3.
Decrease the transmitter power (by decreasing the resistance) until the output is
3
activated.
4 Remove target object. Observe the output deactivates.
Note: If the test input is not to be used (not safety application), it is recommended to connect the
control wire to + (positive) supply wire.

Troubleshooting

Troubleshooting
Probable Reason
1. Symptom: Power indicator (Green LED) on SMT is off.
No power supply
2. Symptom: Output indicator (Yellow LED) on SMR does not correspond to a beam break
No power supply to SMR
TX is not emitting, green LED off
SMT is disabled
The sensors are misaligned
3. Symptom: Output indicator (Yellow LED) on SMR is flickering
Severe electrical interference
Severe ambient light
Cross talk from another light transmitter

SMT Test Input
SMT Test Input
If the sensor is used as a safety device in accordance with EN12978, the function of the
sensor pair has to be tested periodically, at the latest at one of the end positions of the
door leaf. (EN12978:2003+A1:2009: 4.4.3).
During the test the transmitter is disabled by connecting the control wire to – supply
(ground). The control system has to check that the receiver de-energises the output (NC
system). The control wire of the transmitter is hereafter disconnected or connected to +,
and it is checked that the receiver re-energises the output.
Enable transmitter Open (off) control switch, a resistor over 10k ohm, or voltage over 4 V dc
Disable transmitter Close (on) control switch, a resistor below 200 ohm, or voltage below 0,7 V dc
Note: If the test input is not to be used (not safety application), it is recommended to connect the
control wire to + (positive) supply wire.
