The actuator types FlowCon FN.0.2, FN.0.2-
BUS
and FN.0.4 are electrical actuators.
• FN.0.2 is 24V modulating.
• FN.0.2-BUS is 24V modulating with Modbus or
BACnet communication.
• FN.0.4 is 24V 3-point floating and 2-position.
Fitting and Re-tting
Do not connect power to the actuator unless
the actuator is already fitted on the valve
and NEVER install the actuator in closed
position - this may damage the valve. Actu
-
ator is supplied in open position to ensure
easy commissioning of the system.
Mount the actuator on the valve and finger
tighten the connection union. Do not use addi-
tional tools.
In case the actuator will have to be removed, it is
recommended for FN.0.2 and FN.0.4 to electri-
cally open the actuator by activating DIP switch
#6 for easier removal.
For FN.0.2-BUS set DIP switch #1-6 to OFF and
wait until the LED indicator is blinking green.
Hereafter, disconnect power and finger loosen
the connection union. Again, no need for addi
-
tional tools. Please make sure that the actuator
is electrically opened, before re-fitting it on the
valve.
Orientation
Upside-down installation is allowed along with
the standard horizontal and vertical installation.

Summary

Fitting and Re-fitting

Actuator Installation Warning

Do not connect power before fitting the actuator or install in closed position to prevent valve damage.

Mounting the Actuator

Mount actuator on valve and finger tighten the connection union. Do not use additional tools.

Actuator Removal Procedure

Electrically open actuator via DIP switch #6 (FN.0.2/FN.0.4) or retract spindle (FN.0.2-BUS) before loosening union.

Orientation

Allowed Installation Orientations

Upside-down installation is permitted along with standard horizontal and vertical orientations.

Wiring

Sequences and Modes

Start-up Sequence

Actuator calibrates to closing point upon power-up, then enters normal operation mode.

Auto Cycle Sequence

Prevents valve jamming by performing 50% stroke cycle every 3 weeks if no movement occurs.

Electrical Override

Activates valve full opening via DIP switch #6, indicated by blinking red/green LED.

Manual Spindle Override

Allows manual valve operation (open/close) using a magnet on the actuator's right side.

Flush Mode (FN.0.2-BUS)

Temporarily opens valve fully, independent of control signal, for system flushing.

DIP Switch Settings

FlowCon FN.0.2 Actuator DIP Switches

Configuration of DIP switches #1-6 for FN.0.2 functions like override, signal type, and auto cycle.

FlowCon FN.0.2-BUS Actuator DIP Switches

Settings for FN.0.2-BUS DIP switches #1-8 for Modbus/BACnet, BIT settings, and terminal resistor.

LED Status Indicators

FN.0.2 LED Status

LED indications for FN.0.2: green (normal), blinking green (calibration), blinking red/green (override), red (failure).

FN.0.2-BUS LED Status

LED indications for FN.0.2-BUS: green (normal), flickering green (bus comms), blinking yellow (manual spindle).

FN.0.4 LED Status

LED indications for FN.0.4: green (normal), blinking green (calibration), blinking red/green (override), red (failure).

Re-Calibration

FN.0.2 Re-Calibration Methods

Forced re-calibration via DIP switch #6 toggle or electrical 10V-2V signal sequence.

FN.0.2-BUS Re-Calibration

Re-calibration via BACnet (MSV.1=2) or Modbus (register 138=1).

FN.0.4 Re-Calibration

Forced re-calibration via DIP switch #6 toggle.

BUS Programming

BUS Programming of FlowCon FN.0.2-BUS
