FlowCon FNJ Actuators 1B95089 - 01/2023 Wiring FlowCon FNJ (analog) FNJ.1.2 Actuator 0-10V modulating Black Red Grey Orange Input signal 0-10V DC FNJ.1.2-EQ Actuator 0-10V modulating Feedback signal 0-10V DC <2mA Power 24V AC/DC Ground/common Failsafe Mode When power is lost, the actuator will go into fail- safe mode, mandatory that capacitor charging is completed. The actuator will perform failsafe action (close) and fully turn off the actuator. Upon power, the actuator remains in the final failsafe position until charging mode (max. 150 sec) and calibration mode are completed. Here- after the actuator will return to normal operation mode. LED Status The LED indicator is visible through the dark colored transparent connection cover. The LED indication will give the following statuses. Black Red Grey Orange Input signal 0-10V DC Feedback signal 0-10V DC <2mA Power 24V AC/DC Ground/common Start-up / Re-Power Sequence When power to the actuator is turned on, capa- citor charging will be prioritized (max. 150 sec depending on capacitor energy level) during startup and re-powering. After completion of charging mode, the actuator will automatically calibrate to determine closing point. Hereafter it will proceed to normal operation mode (accord- ing to control signal). Closing Point Validation The built-in Closing Point Validation re-confirms the valve’s closing point when the valve is left in fully closed position for a longer period of time. It will perform a short stroke lift and back to closed position every 2 hours if no stroke movement has occurred.
