6.3 Communication with laptop/PC
The StorkAir Maintenance Software can be used for direct communication
between a laptop/PC and the MX. An interface is used for connecting the MX
to the laptop/PC. The possibilities for adjustment and reading are virtually the
same as those for the VU Control Unit. The main difference is that, when you
use a laptop/PC, is that the MX settings can be saved as a file.
6.4 MX network
A network of fans can be built, by interconnecting of a number of MX fans
using the communication connection. The serial connection of each fan is
double, in order to interconnect them. Each fan in the network is programmed
with its own address, via a laptop/PC or a VU Control Unit.
Besides the direct connection between the laptop/PC or the Control Unit with
the network, reading and adjustment can also take place remotely. From the
laptop/PC, a modem can be used to communicate with an MX network at a
different location. The MX network at location must be connected to the
telephone net via a modem or other equipment, for this purpose.

7. Installation
7.1 Installation conditions
• The MX must be installed according to the general and locally applicable
safety and installation regulations.
• The MX must be fitted in such a manner that there is no risk of anybody
touching the suction side of the fan [see EN 294].
• The permissible temperature of the air to be moved is from -30°C to +80°C.
• The fan is designed for continuous operation and may not be switched on
and off more frequently than once every five minutes.
7.2 Transport, storage and unpacking
• The MX must be transported horizontally.
• During storage, the MX must be positioned horizontally.
• The fan should preferably be lifted using the recesses in the side of the
housing or on the base.
• Ensure that the packaging materials are disposed of in an environmentally
responsible manner.
7.3 Checking the delivery
• The type indication and other fan type plate information must match that on
the order.
• The box contains the manual and a bag with mounting bolts and rings,
intended for attaching the MX to a mounting curb.
• For MX-ZMV: the box contains an installation set; a bag with hose column,
clamps and approximately 1.5m hose.
7.4 Installation
General
• It is vital that the roof construction or foundation on which the MX is to be
installed is sufficiently rigid. If it is not rigid enough, undesirable vibrations
may occur during operation of the fan.
• The fan must be installed using the supplied bolts and rings. Ensure that
both the foundation and the surface into which the bolts are screwed are
sufficiently strong to retain the fan even under severe weather conditions.
• The fan must be mounted horizontally to avoid rain and wind blowing into
the fan. The maximum permissible angle of installation is 5° to the horizon.
• The power supply cable, any control cables and possibly a pressure hose
can be fed through a tube leading from under the base of the fan to under
the fan cover. This tube is indicated under the fan cover as ‘supply cable’,
see 7a
. A tube to one of the recesses in the corners of the ventilators can
be used to feed cables to the operating switch. This is indicated by ‘cable’,
see 7a
7a. A = cable, B = supply cable
MX-ZMV:
• A pressure transmitter is fitted under the fan cover, and is electrically
connected to the controls by means of a 3-wire connection.
• An air hose is pre-fitted standard to the inner hose column on the bottom
of the pressure transmitter, which is led through a tube to one of the
recesses on the corners of the fan
[see 7b]
. This hose is used for measure-
ment of the ambient pressure/zero pressure.
• Fix the supplied hose to the outer hose column on the bottom of the
pressure transmitter
[see 7b]
. Lay this air hose via one of the tubes under
the cover, to the place in the unit where the pressure must be measured.
The pressure is generally measured in the mounting curb under the fan
or the Silencer
[see 7b]
.
• The supplied installation set can be used for attachment of the air hose.
The brackets are provided for attachment of the air hose, the cable gland
and the aluminium tube can be used as the pressure measuring point in
the mounting curb
[see 7b]
.
• Ensure the air hose in the pressure measuring point is always fitted outside
of the air flow or close along the wall. When not installed exactly upright, not
only the static pressure is measured but also a dynamic pressure, so that
the regulator cannot react accurately to a constant, static pressure.
