Setting limits L1 and L2
To set the limits, proceed as follows:
1. Drive the actuator to the first desired mechanical position.
2. Adjust the top actuating disc by hand until the output signal on terminals 41 and 42

– Turn the actuating disc over the switching point out until you reach the next switching
point.
Note
To prevent the actuating discs from being accidentally moved during operation, the
actuating discs are designed to be relatively sluggish. You can achieve an easier and
more sensitive adjustment by temporarily reducing the friction. To do this, open and
close the actuator several times while at the same time holding the actuating discs
steady.
