Setting the positions of the inductive limit switches
The function of inductive proximity switches is to shut down the electric
drive before the mechanical end position is reached.
The necessary braking distance (
Δ B) depends on the velocity and
deceleration of the carriage. The braking distance must be between the
switching point of the proximity switch and the actual mechanical end
position.

The limit switches must switch so that the carriage comes to a stop
immediately before the safety zone. The safety zone is factory-marked
on the unit by a band (3).
Procedure
1.
Connect the power to the limit switches.
2.
Slacken the limit switch fixing screws.
3.
Run the carriage as far as the braking position.
4.
Move the limit switch (NC contact) under the switching cam until it
trips and the LED on the sensor goes out.
5.
Move the carriage away.
6.
Tighten the limit switch.
7.
Check the correct position of the limit switch: Move the carriage
manually and observe the switching operation.
8.
Fit the limit switch array covering.
