FlowCon FIT-G DN40-50 (1 1/2”-2”) 11/2024 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 the failsafe version (FH.1), capacitor charg- ing will be prioritized (max. 215 sec depending on capacitor energy level) during start-up and re-powering. After completion of charging mode followed by calibration mode, the actuator will proceed to normal operation mode. 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 inactiv- ity. By moving DIP switch #1 from OFF to ON, Auto Cycle is activated. Actuator will then per- form 50% stroke cycle every 3 weeks if no stroke movement has occurred. Manual Override (FlowCon FH) Before performing manual override, please turn off the power supply. Lift the silicone cap on the top of the actuator to get access to manual over- ride. 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. Electrical Override (FlowCon FH.1) By moving DIP switch #6 from OFF to ON, elec- trical override is activated and the actuator will open valve fully. During electrical override 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 opera- tion mode. Electrical override is performed with power supply on. Failsafe Mode (FlowCon FH.1) When power is lost, the actuator will go into fail- safe mode after a few seconds, mandatory that capacitor charging and start-up sequence are completed. The actuator will perform failsafe action (open or close) and stay in failsafe final position until return of power. Upon power, the actuator remains in the final failsafe position until charging mode is reached (max. 215 sec). Here- after the actuator will return to normal operation mode.
