1.0 Installation of Powerbox FV5OX for on/
off control of airow dampers
• Connect 230V power supply to terminal L and N as
shown in diagram and photo
• Connect terminal 1 and 2 to damper motor 24V
supply
• Connect terminal 14 (beside terminal 1 and 2) to
the damper motor signal input terminal.
• Input terminals 8 and 9 (T4) can be connected to a
possible external open/close control function. When
terminal 8 and 9 are connected Powerbox II will
open the damper independent of power sensors.
• Terminal 10 and 11 can be connected to power
sensor A (induction coil)
• Terminal 12 and 13 can be connected to power
sensor B (induction coil)
• Terminal 15 and 16 can be connected to power
sensor C (induction coil)
• Power sensor A can be connected to a welding
machine or other power-consuming machine.
One electric phase from the supply cable is taken
through the induction coil, and will now induce a
small electric current in the power sensor when the
machine starts. This current will activate the Power-
box IIl unit and make it open the damper.
• It is recommended to install the induction coil
around a free electric phase inside a CEE socket.
The CTS exit will change position simultaneously
with the damper opening and closure
• The CTS contacts can be applied as start and stop
signal to fans or dampers.
After start:
• The installation is controlled by activating the
FV40X. This is done by either pressing the switch
on the front cover or by short-circuiting terminal 8
and 9 in T4. The damper will now open and close.
• Trimmer A and Trimmer B are adjusted when
the machine is stopped. The pot-meter is turned
anti-clock wise until the damper just opens the
damper, and then turned a little reverse. This will
close the damper after short time.
• The setting is veried by starting the machine and
then control that the damper opens, ant that it clos-
es again after the delay time period.
• The delay time period (for after-fume) is adjusted
on the Timer pot-meter.
• The CTS contacts can be applied as start and stop
signal to fans or dampers.
The damper will now open when either:
• The switch on front panel is pushed to “Man”
position.
• Terminal 8 and 9 are short circuited.
• Power sensor A is activated by starting machine A
• Power sensor B is activated by starting machine B
• Power sensor C is activated by starting machine C
• The CTS exit can be connected to a fan or damper
for automatic start and stop

Maintenance:
• Trimmer A, B and Trimmer C can eventually be
readjusted if the damper does not open and close
correctly with the machine.
• The Trimmer for time can also be adjusted for
shorter or longer delay time
• The CTS exit can be connected to a fan or damper
for automatic start and stop.
• Delay time for timer function between
2 secs. - 3 min. +-20%
