FlowCon FH / FH-BUS / FH.1 Actuators 1B95036 - 06/2023 Wiring FlowCon FH (analog) FH / FH.1 Actuator 0(2)-10V modulating Blue Brown Grey Yellow Green Input signal 0(2)-10V DC <0.5mA Feedback signal 0(2)-10V DC Power 24V AC/DC Signal ground Ground/common FH-BUS Actuator RS-485 Serial Black Red Yellow Green White Grey Violet Pink D+ D- P1 P2 Power 24V AC/DC Ground/common FlowCon FH (digital) FH / FH.1 Actuator 2-Position, Normally Closed Blue Brown Grey Yellow Green Close Open Feedback signal 0-10V DC Signal ground Power 24V AC/DC Ground/common FH Actuator 3-Point Floating, Normally Closed Blue Brown Grey Yellow Green Close Stop Open Feedback signal 0(2)-10V DC Signal ground Power 24V AC/DC Ground/common 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 FH-BUS, bus address configuration is re- quired and must be done immediate after first power on. Calibration mode and then normal op- eration mode will follow thereafter. 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. For FH and FH.1, Auto Cycle is activated by moving DIP switch #1 from OFF to ON. The ac- tuator will then perform 50% stroke cycle every 3 weeks if no stroke movement has occured. For FH-BUS Auto Cycle is activated and cycle time configured via the bus (Modbus register 136 and BACnet AV.10; 0= not activated). Re-Calibration (FlowCon FH) By flipping DIP switch #6 from one setting to the other (starting position indifferent) re-calibration is activated. After completed re-calibration the actuator will automatically go into normal ope- ration. During re-calibration mode the LED will blink green.
