SW1 Operational direction of the valve
Off: The valve is closed when the valve stem is in its highest position.
On: The valve is closed when the valve stem is in its lowest position.
SW2 Desired effective characteristic
Off: Effective equal percentage flow characteristics
On: Effective linear flow characteristics.
See more information under
Characteristic curves .
SW3 Reverse/Direct operation
Off: Direct operation. The actuator opens the valve on increasing control
signal.
On: Reverse operation. The actuator closes the valve on increasing control
signal.
SW4 Control signal
Off: 0...10 V DC
On: 2...10 V DC
SW5 Valve flow characteristic
Off: Linear.
On: Equal percentage.
See more information under
Characteristic curves .
SW6 Control signal, type
Off: Voltage 0 (2)-10 V
On: Current 0 (4)-20mA
Characteristic curves
The table below shows settings for switch 2 and switch 5. Switch 2 is the
desired effective function you want out of the valve and actuator
combination. Switch 5 is the flow characteristics of the valve itself.

LED indication
The actuator has two LED lights with indications according to the table
below.
Green LED fixed light Actuator moving, under operation
Green LED quick flash Stroke adaption
Green LED slow flash (Flash twice +
Off 2 sec.) 0 % position
Green LED slow flash (Flash twice +
On 1 sec. + Off 1 sec.) 100 % position
Red LED lights End of SWs fault / more than 2 faults
Red LED quick flash One of End SWs fault
Red LED slow flash (Flash once + Off 2
sec.) Settings changed during operation
Red LED slow flash (Flash twice + Off 2
sec.) Auto stroke adapt fault
Manual override
To set the actuator to manual override, follow these steps:
1. Remove the manual override rubber seal with a screwdriver to have
access to the Allen key hole.
2. Use the 4 mm Allen key to turn the screw.

– Turn the Allen key clockwise to extend the actuator stem. This closes
the valve if the valve itself is closing when valve stem is pushed into the
valve.
– Turn the Allen key counterclockwise to retract the stem. This opens
the valve if the valve itself is closing when valve stem is pushed into the
valve.
Figure 3 Left: Valve is open when the valve stem is extended. Right: Valve is
closed when the valve stem is pushed into the valve.
Note!
If the valve opens when the valve stem is pushed in, the function is
the opposite.
