Installation
If the valve stem lock and valve throat adaptor are not already mounted
on the valve, mount them. Pull the valve stem out as far as possible.
Remove the screws (hex key 6 mm) and clamp from the actuator yoke.
Depress the spring-loaded tab on the drive rod coupling device and fit the
valve stem into the coupling.
Release the tab to connect the valve to the actuator. The position of the
yoke on the valve stem adaptor must be adjusted so that the clamp screw
holes line up with the groove in the valve throat adaptor. If the drive rod
needs to be moved in or out for this, depress the central button of the
control knob and turn it clockwise to extend the drive rod and counter-
clockwise to retract it (see Manual override). Mount the screws and the
clamp. Tighten the screws until the actuator is firmly attached.
Disassembly takes place in reverse order.

Stroke and end position calibration
Stroke and end position calibration is not necessary due to a con-
struction utilizing end position stops. When the valve reaches the end
position, a force is generated. Once the force of the actuator reaches
a predefined level, the limit switch automatically halts the drive motor.
Override
Activation of the override input will force the valve to the maximum
open position.
Manual override
90º
To manually set the valve position, first depress the central part of the
knob, until it clicks and remains depressed (1 in the figure). Then the
valve position can be changed manually by turning the knob (2 in the
figure). When the knob is turned clockwise, the drive rod is pushed
outwards and when the knob is turned anti-clockwise, the drive rod is
G0 G pulled inwards.

To return to normal operation, set the knob so that it is in line with the
4 3 2 1 6
text "Auto" on the cover. Then depress the outer parts of the knob (3
in the figure). The central depressed part will pop out, and the actua-
tor will return to normal operation.
Note: After any manual operation the actuator will always run through
a zero point calibration.
DIP switches
There are five DIP switches for setting different functions. Follow the
table below for setting the DIP switches.
Adjusted settings will be valid only after the next power-on.
