Commissioning Steps
1. Testing for proper actuating device installation and testing the electrical connection
2. Adjusting the valve functions
The valve function is adjusted using the 4 switches beneath the emergency
actuator hood.
(1)
Switch:
Switch on/switch off
Factory setting:
0 (Aus)
valve block protection
(2)
Switch:
Setting of the control
Factory setting:
0-10V
range of the actuating signal
0-20mA
(3)
Switch:
Setting of the actuating
Factory setting
: V
signal Y and position feedback
live or energized
Feedback when the valve is blocked or during manual adjustment is
-energized feedback signal > approx. 12.5 V
-live feedback signal 0 mA (with 4–20 mA)
(4)
Switch:
Sequence setting for controlling
Factory setting:
the actuating direction
“valve open” or “valve closed”
(e.g. DC 0–10 V or DC 10–0V)
Position feedback
Note
Inverting the control signal ( , ) also adjusts the sequence of the position feedback. The control signal and
the actuating feedback are coupled to each other in their sequence.

3. Switch on the power supply
LED (2) flashes.
4. Initialization, adjustment to valve stroke
The initialization run is switched on by pressing the INIT key (3).
The valve is completely opened and closed once during
initialization. LED (2) flashes during initialization. The
emergency actuator always moves first to the upper end
position and then to the lower end position.
The LED remains constantly lit to signal that initialization is
completed. The INIT key and the LED are located beneath the
drive hood (see illustration).
5. Valve block protection
Block protection prevents the ball from jamming when the valve is not moved for a longer period of inactivity,
e.g. for heating systems, during the summer. When block protection is activated, the valve ball is lifted fo several
seconds if there is no stroke movement for 24 hours. Block protection is not activated when the unit is delivered.
If plant specifications permit, the valve block protection feature may be activated. Valve block protection can be
switched on during the initialization phase.
Switch on:
Valve block protection is switched on and off using switch (1), which is located beneath the drive
hood.
6. Manual adjustment
Remove the emergency actuator cover for manual operation. Using the hexagon socket key (key
socket 4 mm), the valve can be moved into any position. The knob is then used to lock the
emergency actuator.
