• Installation and adjustment
1. Switch off power supply
2. Connect sensor 1 to the power supply station. Make sure that the correct voltage value is
adjusted. Max. 30 sensors can be connected together. The power supply is linked from one
switch to the other via M12-connector.
3. Fix sensor, by using an adequate mounting bracket, in the middle of between the conveyer rolls
and twist the case slighty backward (2-5°)
4. Turn black-coloured distance adjustment knob (Pos. 40) and yellow coloured screw (Pos. 60) for
near-side-detection carefully counterclockwise until minimum position is reached
5. Switch on power supply
6. At first adjust the sensing distance by turning the black knob, that at least 5 % of the switching
distance value can be guaranteed related to the reflecting background (check by using a Kodak
Gray Card with 90 % reflectivity)
7. Activate near-side detector by turning the yellow-coloured knob (Pos. 60) clockwise - the red LED
should not blink and should light permanently when the object is detected. Otherwise increase
sensitivity by turning the yellow knob clockwise
8. When object is removed, the red LED should not light or blink
Recommended adjustment
The adjusted sensing-distance of the near-side detector should not exceed the BGS-Setting-
distance.
Correct operation
The moving direction of the sensor or object should be
preferably along the optical axis of the light beam. Lateral
approach is also possible. Movement from the top to the
bottom or opposite can case malfunction and should be
avoided.
In case of installing two sensors facing each other, the
optical axis should be moved to prevent any mutual
interference.
Avoid influences of any strong ambient light sources that
can decrease the sensitivity of the sensor or cause instable working condition.
Connections and precautions
If the input/output lines of the photoelectric sensor are placed in the same conduit or duct as power
lines or high-voltage lines, the photoelectric sensor could be induced to malfunction, or even be
damaged by electrical noise. Either separate the wiring or use shielded lines as input/output lines to
the photoelectric sensor.
The cord connected to the Sensor can be extended up to 50 m provided that the diameter of each
wire is 0,3 mm²minimum.

Maintenance
Normally the F3C doesn’t need any maintenance. Only the optical surfaces should be cleaned from
time to time by using a soft cloth.
Startup Operation
A maximum of 300 ms is required from the time power is turned on until F3C is able to detect
objects. If power is supplied to the loads and the F3C from different sources, turn on power to the
F3C first.
Water resistivity
Do not use F3C in water, in rain or outdoors.
Accessories
Standard mounting bracket for easy installation.
