FlowCon FNQ.0.2 and FNQ.1.2 Actuators 1B95085 - 06/2020 Wiring FlowCon FNQ (analog) FNQ.0.2 / 1.2 Actuator 0(2)-10V modulating Black Red White Green Input signal 0(2)-10V DC Feedback signal 0(2)-10V DC 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 the failsafe version (FNQ.1.2), capacitor charging will be prioritized (max. 140 sec de- pending 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. Manual Override To perform manual override, please turn off power supply and press the release button while turning the top part of the actuator counter clock- wise 30°. Hereafter, the valve adaptor knob can be manually adjusted. WARNING: Do not force the knob in either direction and NEVER use higher torque than 1 Nm. Failsafe Mode (FlowCon FNQ.1.2) When power is lost, the actuator will go into fail- safe mode after a few seconds. The actuator will perform a failsafe action (open or close) and stay in failsafe final position until return of power or for approximately 7 minutes before the actuator shuts off. Auto Cycle Sequence Activated Auto Cycle prevents the ball from jam- ming when the valve is kept inactive in the fully open or fully closed position for a longer period. When activated, the actuator will then move a full cycle every 24 hours if no stroke movement has occurred. This will clear any possible impu- rity build-up inside the valve and re-calculate the end positions.
