Wiring 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 (FN.1.2), capacitor
charging will be prioritized (max. 120 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.
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.
Failsafe Mode (FlowCon FN.1.2)
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. 60 sec). Here-
after the actuator will return to normal operation
mode.
