The actuator types FlowCon FH and FlowCon
FH.1 are electrical, high force actuators. FH is
all-in-one including 24V modulating, 3-point floating
and 2-position. FH.1 is 24V modulating and
2-position failsafe version.
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 to electrically open
the actuator for easier removal. Hereafter finger
loosen the connection union. Again, no need for
additional tools. Please make sure that the ac-
tuator is electrically opened, before re-fitting it on
the valve.
Orientation
Upside-down installation is allowed along with
the standard horizontal and vertical installation.

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 (FH.1), capacitor charg-
ing will be prioritized (max. 215 sec depending
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 commis-
sion ing. It prevents the valve from jamming when
the valve is not moved for a longer period of in-
activity. By moving DIP switch #1 from OFF to
ON, Auto Cycle is activated. Actuator will then
perform 50% stroke cycle
every 3 weeks if no
stroke
movement has occured.
Re-Calibration (FlowCon FH)
By flipping DIP switch #6 from one setting to the
other (starting position indifferent) re-calibration
is activated. After completed re-calibration the
actuator will automatically go into normal ope-
ration. During re-calibration mode the LED will
blink green.
Manual Override (FlowCon FH)
Before performing manual override, please turn
off the power supply. Lift the silicone cap on the
top of the actuator to get access to manual over-
ride. Manual override is performed by a 4 mm
(~5/32”) hex key. Clockwise turning will open the
valve and counter-clockwise turning will close
the valve.
Electrical Override (FlowCon FH.1)
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 FH.1)
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 ac-
tion (open or close) and stay in failsafe final posi-
tion until return of power. Upon power, the actua-
tor remains in the final failsafe position until charg-
ing mode is reached (max. 215 sec). Hereafter the
actuator will return to normal operation mode.

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.

LED Status
The LED indicator is visible through the dark
colored transparent connection cover. The LED
indication will give the following statuses.
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.
