Setting the two limit values:
1. Drive the actuator to the first desired mechanical position.
2. Adjust the top actuating disc (7.2) by hand until the output signal
on terminals 41 and 42 changes.
3. Drive the actuator to the second desired mechanical position.
4. Adjust the bottom actuating disc (7.3) by hand until the output sig-
nal on terminals 51 and 52 changes.
.
NOTE
To avoid the actuating discs (7.2/7.3) being accidentally adjusted du-
ring operation, they are relatively sluggish. The following remedy might
be of help if you are having trouble with the adjustment: open and
close the actuator several times while holding the actuating discs. This
temporarily reduces the friction. This allows an easier and finer adjust-
ment.
2.7.7 EMC filter module
The positioner can also be driven by an external position sensor (po-
tentiometer or NCS) (see page 46 “3.3.2 Instructions for using position-
ers which are exposed to strong accelerations or vibrations”). An EMC
filter module, order number C73451-A430-D23, is required for this.
