Setting the limits of the mechanical limit switch module

Setting the L1 and L2 limits
Proceed as follows to set the limits:
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disc manually until the output signal at terminals 41 and 42
changes. Set a high-low or a low-high switchover as follows:
3. Move the actuator to the second desired mechanical position.
4. Adjust the lower actuating disc manually until the output signal at terminals 51 and 52
changes. Set a high-low or a low-high switchover as follows:

Function
You will require the EMC filter module if you use an external position sensor on the
positioner, e.g. a potentiometer or a non-contacting position sensor. The EMC filter module
forms the interface between external position sensors and the motherboard of the positioner.
This module protects the positioner from electromagnetic effects.
Device features
Device features include:
● EMC protection
● Connection to motherboard
● Connecting terminals for an external potentiometer

– Rotate the actuating disc beyond the switching point until you reach the next switching
point.
– Rotate the actuating disc beyond the switching point until you reach the next switching
point.
Note
The actuating discs are relatively difficult to move. This design prevents their
unintentional movement during operation. You can achieve an easier and finer
adjustment by reducing friction temporarily. Move the actuator to and fro while
simultaneously holding the actuating discs.
