6.1 Installation instructions
The operating conditions at the mounting location must not affect the functioning of the optoelectronic
sensors. Please note especially:
•
The transmitter and the receiver must not be affected by intensive light sources (emitters, sunlight
etc.).
•
The ambient temperature must be within the range indicated (→ Data sheet).
•
Fogging of the lenses due to considerable temperature fluctuations can affect the functioning of the
optoelectronic sensors. Take appropriate measures to prevent this.
•
Certain operating conditions can affect the functioning of the optoelectronic sensors. For mounting
locations where fog, rain, smoke or dust may occur, it is recommended to take appropriate
measures.
The calculation of the range depends on environmental conditions.

6.1.1 Fastening
Correct alignment of the transmitter and the receiver is essential for the proper function of the
optoelectronic sensors.
u
Install the transmitter and the receiver using the supplied mounting accessories so that they are
exactly opposite each other.
u
Align the transmitter and the receiver so that they are in parallel at the same height and the plugs
face the same direction.
If vibrations are to be expected in the application, it is recommended to use vibration dampers
