Kongskilde MultiAir FC Manuel D'installation

Installation of pressure / flow control - MultiAir FC / FCE
Connection of pressure- or flow control unit (acces-
sory)
In case you wish to use the blower´s built in PID control
to maintain a fixed pressure or volume flow from the
blower, a pressure- or flow control unit must be con-
nected to the blower´s control unit.
Kongskilde recommends to utilize Kongskildes stand-
ard pressure- or flow control device for automatic
operation.
In both the pressure- and flow control device package,
an external differential pressure transmitter is used,
in addition to either an pipe installed aperture or pipe
installed pressure outlet. Both packages also includes
hose and fittings.
IMPORTANT: The pressure transmitter must be mount-
ed on firm ground without vibrations, ie. not onto the
pipe system or the blower. Furthermore, the pressure
outlet / aperture must be mounted at a distance of at
least 20 x pipe diameter from the blower, otherwise the
operators panel will not display the correct values for
pressure and flow.
The pressure - or flow control packages can be ordered
under the part no´s:

When connecting pressure- or flow control units, the
wires from the differential pressure transmitter must be
connected to the blower´s terminal block as follows:
1 - The right blower cover is removed (seen from the
motor side).
2- Guide the differential pressure transmitter´s wire
through an M20 cable relief (not supplied), and attach
the relief in the base frame.
3 - The terminals are released with a small screwdriver,
and the wires installed according to the diagram:
• terminal 1 (+24VDC) to terminal 2 of the transmitter
• terminal 10 (4-20mA signal) to the terminal 1 of the
transmitter
• possibly a connection from terminal 2 (0VDC) to
the transmitter should be established, in case this
is needed for the transmitter (not required at Kongs
kildes flow- or pressure transmitter).
4 - The cable relief is tightened and the blower cower
refitted.
5 - The differential pressure transmitter is mounted onto
a vibration-free surface.
6 - The transmitter lid is removed, wires are connected
according to the diagram, and the lid reinstalled.
7 - The hoses from the aperture (at flow control) or
pressure outlet (at pressure control) are connected ac-
cording to the illustration. 4 m of clear hose is included,
this can be extended if needed.
