FlowCon FNP Actuators 1B95070P - 09/2021 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). 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. Electrical Override 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. DIP Switch Settings The valve functions are set on DIP switches found under the connection cover. PCB mounted electri- cal components will not be directly exposed when DIP switches are to be set. Factory setting for all switches is OFF.

FlowCon FNP Actuators 1B95070P - 09/2021 LED Status The LED indicator is visible through the dark colored transparent connection cover. The LED indication will give the following statuses. Normal operation mode Calibration mode (closing point adjustment) Electrical override mode FNP Full on green Blinking green Blinking red/green Perpetual failure mode Full on red Re-Calibration Re-calibration can be achieved in one of 2 ways: 1. Forced individual actuator re-calibration can also be performed by flipping DIP switch #6 from OFF to ON and back to OFF on the rele- vant actuator. 2. Forced concurrent re-calibration for all actua- tors is electrically possible. Within 60 sec. provide the following electrical control signal sequence to the grey wire: 10V-2V-10V-2V- 10V-2V to achieve re-calibration. After re-calibration the actuator will go into normal operation mode.
