Start / stop contact
The external start / stop switch is connected in terminal
block X30 between terminal 1 (+ 24VDC) and 3 (Digital
Input 0), and a loop is installed between terminals 1
and 4.
On the operator´s panel should:
Digital Input 0 be set to
External start signal - hold
and
Digital Input 1 be set to
External stop NC.
Make sure that the blower is installed so that it is se-
cured against falls and tipping over.
If the blower is to be moved, a forklift or similar device
should be used, which lifts from underneath the blower
base frame. The forks must be long enough to lift both
sides of the blower.
Ensure that there is a sufficient supply of fresh air to
the room from which the blower takes in air.
Please ensure that the blower is installed so that there
is easy access for operation and maintenance.
The blower must be installed on a stable surface which
is levelled and horizontal. Adjust the machine shoes
under the blower so that they support uniformly on the
surface. It is not necessary to secure the blower to the
surface.
The MultiAir FC blower is rated for ambient temperature
of -10°C - 50°C. If the temperature exceeds 50°C, the
blowers lifetime could be reduced.
NB - after connection of power to the blower, a delay
of up to half a minute may occur, before the operator´s
panel is lit.
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. Bear in mind that the joints of the pipe sys-
tem must be tight, as leaks will reduce the conveying
performance.
Electrical installation:
The MultiAir blower is delivered in version for 380 -
480V voltage. If the blower is to be installed in the 200-
240V and 480 - 575V voltage range, an external trans-
former must be installed between the power supply and
the blower.
All local factory inspectorate regulations must be com-
plied with.
Check that the on site electricity supply is suitable for
the MultiAir blower.
See also the separate instructions for the blower´s elec-
trical equipment, that is supplied the blower.
NB - above the supply cable´s relief and potential
equalizing terminal in the base frame, are 6 cutouts for
cable reliefs. These can be used for control wires, dif-
ferential pressure transmitter connection, digital
input and output connections, etc.
