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 moving DIP switch #1 from OFF to ON.
The actuator will then perform 50% stroke cycle every 3 weeks if not stroke movement has occurred.
Override
Electrical override is activated by moving DIP switch #6 from OFF to ON.
Then the valve will open fully.
During override mode the LED indicator will blink red and green.
When DIP switch #6 is moved back to OFF, the actuator will re-calibrate and thereafter go into nor-
mal operation mode.
Electrical override is performed with power supply on.
DIP Switch Settings
The valve functions are set on DIP switches found under the connection cover. PCB mounted electri-
cal components will not be directly exposed when DIP switches are to be set. Factory setting for all
switches is OFF.
