Start-up Sequence
When power to the actuator is turned on, the actuator will automatically calibrate to determine closing
point. Hereafter it will proceed to normal operation mode (according to control signal).
Auto Cycle Sequence
Auto Cycle can be activated during commissioning. It prevents the valve from jamming
when the valve is not moved for a longer period of inactivity. Auto Cycle is activated by mov-
ing DIP switch #1 from OFF to ON. The actuator will then perform 50% stroke cycle every
3 weeks if no stroke movement has occured.
Re-Calibration
By flipping DIP switch #6 from one setting to the other (starting position indifferent) re-calibration is acti-
vated. After completed re-calibration the actuator will automatically go into normal ope-ration. During re-
calibration mode the LED will blink green.
Override
Manual override is performed after power supply is turned off. Lift the silicone cap on the top of the actuator
to get access to manual override. Manual override is performed by a 4 mm (~5/32") hex key. Clockwise
turning will open the valve and counter-clockwise turning will close the valve.
DIP Switch Settings
The valve functions are set on DIP switches found under the connection cover. PCB mounted electrical
components will not be directly exposed when DIP switches are to be set. Factory setting for all switches
is OFF.
