Mechanical Mounting
Please mount the light curtains in proper alignment as shown in the pictures below by using
the brackets provided with the light curtains.
If F3ET2 is installed at long distances the laser alignment aid F39-TGR-LLK2-CL provides a
visible laser spot for simplified installation.
If several light curtains are installed close to each other, interference of the light curtains must
be avoided. In this case the assembly should be carried out as follows:
2-3 Operating environment
The area for the installation of the light curtain must be suitable according to the technical
specifications. The temperature of the environment, interference caused by electromagnetic
disturbance and ambient light must be considered. Please contact the manufacturer for any
information not contained in this manual.
2-4 Operating distances
The operating distances, which are given in the technical specifications, are guaranteed values
for reliable operation. Operating F3ET2 above the specified sensing distance may cause
greater sensitivity to vibration and possible electromagnetic disturbances.
If the F3ET2 is operated in a distance <1m, the sensitivity can be set to NEAR operation by
dip-switch setting at transmitter (see ’ DIP switch setting’ on page 2-7).
This should be considered for following application conditions:
a) Multiple light curtains are installed close to each other (avoiding mutual interference)
b) Detection of small or semi-transparent objects
If none of above mentioned cases applies, FAR setting should be kept in order to provide
maximum detection reliability.
