For serial output models the STROBE input can be used for easier alignment. Please follow
this procedure:
• Turn on the light curtain with the STROBE input connected to +24 VDC
• Move the light curtain to reach the alignment using the led indication on receiver (see led
table 5-1)
• Turn off the light curtain and remove the +24 VDC strobe input connection
If F3EM2 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 F3EM above the specified sensing distance may cause
greater sensitivity to vibration and possible electro magnetic disturbances.
If the F3EM2 is operated in a distance <1m, the sensitivity can be set to NEAR operation by
dip-switch setting at transmitter (see '4-1 DIP switch setting' on page 4-2).
This should be considered for following application conditions:
If none of above mentioned cases applies, FAR setting should be kept in order to provide
maximum detection reliability.
