pin is in the slot of the follower plate.
Make sure the lever can still move.
Attachment to rotary actuators
4
Lever M pin position 90°
4
Put the valve into the closed position,
determine the opening direction.
4
Place the follower plate on the slotted
actuator shaft and fasten it to the
coupling wheel. Attach the top pair of
brackets and the bottom pair of brackets
to the actuator.
4
Place the positioner on the brackets and
screw tight, making sure that the lever
with its follower pin engages the slot of
the coupling wheel, while taking into
account the opening direction.
It is important to make sure that the
lever's mid position corresponds to the
mid travel of the valve (lever's mid
position = the lever is parallel to the long
side of the positioner housing).
Pneumatic connections
4
Screw the threaded parts only into the
attached connection block, connecting
plate or pressure gauge block from the
accessories.
8.2 Start-up
4
Connect pneumatic supply air (1.4 to
6 bar).
4
Route the two-wire bus line to the screw
terminals marked “IEC 1158-2”, a
particular polarity does not need to be
observed.
Alternatively, the power supply for the
positioner can be supplied over a DC
voltage source (9 to 32 V) connected to
the bus terminals in the positioner.
You are required to observe the
relevant regulations for use in
hazardous areas.
Set the valve closed position
Position the slide switch according to closed
position of the control valve:
AIR TO OPEN or AIR TO CLOSE.
Adapt the volume restriction Q to the
actuator size
Only set the restriction for actuators
< 240 cm² to:
MIN SIDE for connection at the side or
MIN BACK for connection at the back.
NOTICE
After each change of the volume restriction
setting, the positioner must be re-initialized.
