The Multiair fan is designed so that

it can be installed outdoors. If the

fan is delivered with a flow or pres-

sure control, the pressure transmit-

ter must be mounted on a solid

surface without any vibration.

Installation of the pipes

The conveying performance of a

pneumatic conveying system is

highly dependent on the layout of

the piping. It is therefore important

to follow the layout that has been

designed for the pipe system for

the installation in question. Remem-

ber also that the joints of the pipe

system must be tight as leaks will

reduce the conveying performance

Maintenance

Lubrication

The motor bearings are lubricated

at the factory and require no ad-

ditional lubrication. The fan rotor

is mounted directly on the motor

shaft; there are therefore no

bearings in the fan itself.

Cleaning

Make sure that there is always an

unobstructed flow of cooling air to

the Multiair fan motor. Clean the

grid by the cool air intake to the

motor for any impurities.

Start/stop

Using the electrical equipment and

control panel it is possible to fully

regulate the fan speed. It is there-

fore possible to adjust the Multiair

fan performance to fit precisely the

application concerned.

The adjustment can either be done

manually or it can be done auto-

matically by means of a pressure

transmitter (optional).

To achieve energy savings it is im-

portant not to run at higher speeds

than what is necessary to solve the

task at hand. Operating the fan at

excessive speeds/output could

cause damage to the material

being conveyed.

The electrical equipment

should be opened only by

qualified or trained per-

sons.

Remote Start/Stop

If remote start and stop function is

required Kongskilde recommends

to follow this procedure:

1) Please refer to the electrical

schematics for the Multiair in

question.

2) Remote start: Using a potential

free set of contacts (external),

normally open (NO) the blower

+24VDC for m X4.5 is con-

nected together with X4.6 which

is the digital input used for the

start function pulse. The poten-

tial fee set of contacts just have

for be pulsed for the Multiair to

start. DIP Switch 3 have to be

on position ON to activate the

Remote start.

3) Remote stop: Using a potential

free set of contacts (external),

normally closed (NC) the blow-

ers +24VDC from X4.3 is con-

nected together with X4.4. The

potential free set of contacts

will now needed to be pulsed

(opened) for the Multiair blower

to stop. DIP Switch 5 have to be

on position ON to activate the

Remote start.

Potential free status

signals

The Multiair blower controls are

equipped with 2 potential free set

of contacts which enables external

monitoring of the blowers running

status. See the electrical schemat-

ics for the Multiair blower in ques-

tion.

Run signal: Potential free, nor-

mally open (NO) contacts can be

found on terminal X3.3, X3.4 (Max

24VDC).

Fault signal: Potential free, nor-

mally closed (NC) contacts can be

found on terminal X3.5, X3.6 (max

24VDC).

Manual operation or

automatic operation

(PID)

Select the desired operating mode

using the DIP switch 1 marked with

"OFF:PID ON:MANUEL" (see pic-

ture 1 /page 15), which is located

inside the Multiair fan on the motor

control box (see picture 2/page 15).

If the system is connected to flow

or pressure control equipment, set

the DIP switch 1 in position "OFF:

PID for automatic control of perfor-

mance in relation to an adjustable

set-point.

If there is no pressure transmitter

connected, set the DIP switch 1 in

position "ON: MANUEL" for manual

operation.

It is usually only necessary to choo-

se between manual and automatic

operation when the Multiair fan is

started up the first time, as this set-

ting is application specific.
