Alignment

Mechanical mounting:
It is extremely important to secure the light curtains to a rigid structure, not subject to deformation or 

strong vibrations.
Decide where to place the Receiver so that it is not subject to strong natural or artificial light sources or to 

luminous interference of other sensors.
Place the Emitter and Receiver facing one another, at the same height above the reference plane, following 

the same orientation. The output wires of the transmitter and receiver must be on the same side.
The distance between the two elements must not exceed the limits set by the specifications. 
The optical beams can be partially deflected by nearby reflective surfaces. Because of that, the path beam 

interruption may not be detected. Therefore, all reflective surfaces and objects should be placed at a  

minimum safe distance from the optical beam path.

Safety Information

WARNING:

 

This it is NOT a protective device. Therefore, it should not be used to  

guarantee personnel safety.
This is a low-voltage, direct current device. Proper functioning is only  

guaranteed between 16, 8VDC and 30VDC. Under 15VDC voltage all  

outputs are in an OFF state.  Over 30VDC voltage may damage the device.

When the device is switched on, outputs are inactive for a certain amount of 

time known as Time Delay Before Availability.
The Emitter emits near-infrared light at non-dangerous levels. The device is 

classified as RG0 (exempt) according to IEC 62471: 2006-07.
•  Please make sure that light curtains are used in proper environmental 

conditions.

•  Automatic calibration must always be carried out aiming for the best 

possible alignment. More than one calibration and alignment adjustment 

may be  

necessary to guarantee the best alignment.

•  Check any reflective surface next to the light beams which may influence 

them.

•  Check any transparent panels or similar panels which may change the 

beam angle of the light curtains.

•  Prevent the light curtain’s optical window from getting scratched or  

tarnished.

•  Do not expose the receiver to strong natural or artificial light sources, 

including stroboscopic light.

•  Do not expose the receiver directly to optical beams projected by other 

optical devices.

•  Ensure that the ambient temperature does not exceed the stated limits.

•  Bear in mind that smoke, vapor, liquids and powders may alter  

transparency of air or dirty the optical window.

•  Always dispose of unusable or irreparable devices always in accordance 

with national regulations regarding waste disposal.

Startup

The system must be aligned.
1.  All connections between emitter and receiver must be made. (See section 2.)
2.  Connect the NO/NC as you wish the system to respond. (For NO connect to 

common or leave open. For NC connect to 24 VDC).

3.  Teach input must be open.
4.  Power on the system.
5.  Connect the Teach input momentarily to the common (Teach Fine command) 

and wait for the end of Teach-in (wait for illumination of the Green and Blue 

LED).

6.  Insure maximum alignment by adjusting the position of the sensor.
7.  Mechanically fix the system, making sure to maintain the alignment.
8.  Determine which teach function that you need for your system: fine or gross. 

Fine Teach allows for the smallest detectable object. Gross Teach will avoid 

pitfalls in the stability and repeatability of performance and is less  sensitive to 

environmental conditions. For these reasons, Gross Teach is preferred.

9.  For Gross Teach connect the input momentarily to the 24VDC and for Fine 

Teach connect the input momentarily to the common. The yellow LED of 

the Emitter starts to blink. 

10. In the Emitter, wait until the Yellow LED becomes constantly ON and the 

Red LED remains OFF. In the Receiver, the Red LED turns OFF. Your 

sensors are now set up and ready for testing.
