FlowCon FN.0.2 User Manual

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 FN.0.2-BUS, bus address configuration is
required and must be done immediate after first
power on. Calibration mode and then normal op
-
eration mode will follow thereafter.
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
inactivity. For FN.0.2 and FN.0.4 Auto Cycle is
activated by moving DIP switch #1 from OFF to
ON. The actuator will then perform 50% stroke
cycle every 3 weeks if not stroke movement has
occurred.
For FN.0.2-BUS Auto Cycle is activated and cy
-
cle time configured via the bus (Modbus register
136 and BACnet AV.10; 0= not activated).
Override
For FN.0.2 and FN.0.4 electrical override is acti-
vated by moving DIP switch #6 from OFF to ON.
Then the valve will open fully. During override
mode 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 operation mode. Electrical override is
performed with power supply on.
When performing the manually override proce
-
dure on the FN.0.2-BUS, set DIP switches 1 to
6 to OFF and the spindle will fully retract, and
the LED will rapidly blink green. In this state the
valve can be manually close or opened using a
magnet.
To extend actuator spindle and fully close the
valve, briefly swipe the magnet along the right-
hand side of the actuator (top view and wires
downwards). LED indicator is blinking yellow
during this ‘manual spindle adjustment’ mode. To
retract the actuator spindle and open the valve
fully (mounting position), again briefly swipe the
magnet along the right-hand side of the actuator.
LED is blinking rapidly green to indicate ‘mount
-
ing position’ mode. Manually override can be re-
peated as often as necessary.
Flush Mode (FN.0.2-BUS)
The automatic Flush Mode is activated and
cycle time configured via the bus (Modbus reg
-
ister 132 and BACnet AV.35; 0= not activated).
In Flush Mode, the valve is temporarily fully
opened independent of the control signal to al
-
low easy system flushing.
