Position the roller lever of the CLOSED
limit switch approx. 1 mm above the lower
spindle guide by turning the adjusting
screw 4 (3 mm flat head).
Connect the supply voltage to terminal 2
(L) and terminal 3 (N)
→ actuator moves into the CLOSED
position.
Hold the indicator spindle by the red
marking
→ actuator closes fully until motor stalls.
Release the indicator spindle.
Disconnect the power supply.
Loosen the trip cam bolt using an Allen
key (size 1.5).
Push the indicator spindle downwards
and fasten the trip cam bolt so that the
trip cam actuates the roller lever of the
CLOSED limit switch = switch point.
Continue to turn the adjusting screw 4
1 1/2 turns clockwise (jam safety). (By
continuing to turn the adjusting screw
clockwise, it is possible to slightly reduce
the pre-tension on the diaphragm,
which will extend the service life of the
diaphragm. However, if it is turned too far,
the valve will no longer seal properly.)
Check for leaks.
Fix the CLOSED limit switch in position
with limit switch fixing screws 5 .
2. Setting the OPEN limit switch:
(Prerequisite: valve body and diaphragm are
already mounted, CLOSED limit switch set
as shown on left.)
Loosen the limit switch fixing screws 6 ,
but do not remove them (Philips head
PH 1).
Move the actuator in the OPEN direction
past the CLOSED limit switch and then
back into the CLOSED position until the
CLOSED limit switch cuts out.
Move the OPEN limit switch upwards
as far as the limit stop by turning the
adjusting screw 3 clockwise (3 mm flat
head).
Move the actuator in the OPEN direction
until the stroke length in the table below
is reached and switch off immediately
→ stroke length must correspond exactly.
Move the OPEN limit switch downwards
until the switch point is reached (audible
click) by turning the adjusting screw 3
anticlockwise.
Fix the OPEN limit switch in position with
limit switch fixing screws 6 .

3. Setting the potentiometer
( functional module AP ) :
(Prerequisite: valve body and diaphragm are
already mounted, CLOSED limit switch and
OPEN limit switch are set as described on
the previous page.)
a) Installing the potentiometer:
To install the potentiometer support plate,
loosen the 4 motor mount screws.
Slide support plate between
(attention: do not lift the motor too far
→ the toothed belt will otherwise slip off).
Replace the long bolts with short bolts
(on the potentiometer).
