This is the time from giving a 24V power signal until the actuator starts to move. This is particular important if using a pulse power signal.

FlowCon FN.0.2, FN.0.2-BUS and FN.0.4 1B95080 - 06/2023 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). For FN.0.2-BUS, bus address configuration is required and must be done immediate after first power on. Calibration mode and then normal op- eration mode will follow thereafter. Auto Cycle Sequence Auto Cycle can be activated during commission- ing. It prevents the valve from jamming when the valve is not moved for a longer period of inactivity. For FN.0.2 and FN.0.4 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. For FN.0.2-BUS Auto Cycle is activated and cy- cle time configured via the bus (Modbus register 136 and BACnet AV.10; 0= not activated). Override For FN.0.2 and FN.0.4 electrical override is acti- vated 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 normal operation mode. Electrical override is performed with power supply on. When performing the manually override proce- dure on the FN.0.2-BUS, set DIP switches 1 to 6 to OFF and the spindle will fully retract, and the LED will rapidly blink green. In this state the valve can be manually close or opened using a magnet. To extend actuator spindle and fully close the valve, briefly swipe the magnet along the right- hand side of the actuator (top view and wires downwards). LED indicator is blinking yellow during this ‘manual spindle adjustment’ mode. To retract the actuator spindle and open the valve fully (mounting position), again briefly swipe the magnet along the right-hand side of the actuator. LED is blinking rapidly green to indicate ‘mount- ing position’ mode. Manually override can be re- peated as often as necessary. Flush Mode (FN.0.2-BUS) The automatic Flush Mode is activated and cycle time configured via the bus (Modbus reg- ister 132 and BACnet AV.35; 0= not activated). In Flush Mode, the valve is temporarily fully opened independent of the control signal to al- low easy system flushing.
