3.2 Principle of operation
FanSet is a device used to supply and exhaust air. The engine, mounted in the housing, drives the
impeller located inside. The fan, after accelerating to the dedicated rotational speed, is able to force
fan. Ventilating cone of dedicated diameter is mounted on the opposite side. All parts are made of
high quality materials:

be caried out with
proper dimensional requirements.
For the outlet side the proper clearence [A] is equal to 1.2 x impeller diameter (1.2 x D) The
recommended cleareance at the inlet side [B] should be equal to half of the impeller
diameter (D/2).

3.4 Air volume measuring
FanSet units are equipped with the inlet cone. Air volume measuring device with circular lead is
direction . With the assistance of the measuring device it is possible to control the air volume
depending on the difference in pressure between the static pressure at the inlet cone and the static
pressure on the inlet area. This sensor cannot measure the dynamic pressure in the inlet area. While
Fan Set is tested it is possible to regulate air volume.
The air volume is calculated according to the following formula.
The label consists of the following

Drives uses the two-wire system where the communication between master and slave is half duplex,
i.e. it cannot transmit and receive at the same time. Each signal uses one twisted pair line — two
wires twisted around themselves. The signal on one wire is ideally the exact opposite of the signal
on the second wire. Since RS-485 is a multipoint communication system, all devices are connected
to the single twisted-pair cable. The Modbus RTU uses master/slave architecture, where each slave
device has its unique address and responds only to packets addressed to this device. The packets
travels over the single line in both directions. Multiple EC drives can be connected to a control

Thermal protection: The electronics are equipped with reducing thermal protection. This function is
a temperature limiter which reduces the output power, when temperature on the controller rises over
Under and over voltage: The electronics are equipped with under and over voltage protection.
Electronics shutdown when the main voltage is not in the required range. See mechanical and
Blocked rotor protection: the electronics are equipped with blocked rotor protection when the rotor
of motor is blocked or it is impossible to rotate it. Electronics automatically retries 25 restarts, than
a manual restart by disconnecting the power supply is required.
Motor phase fail/lose: The electronics are equipped with motor phase fail protection in event
in which one of phase motors is damaged or missing. In such case, electronics stops the motor
immediately.

5 MAINTENANCE
5.1 Maintenance
Swiss Rotors strongly recommends checking the condition of fans systematically. Technical control
is obliged to the user. Properly frequent checks allow early detection of irregularities in the system
and may help avoiding serious damages resulting from various random factors. Please refer to our
general proposed inspection checklist presented below.
Phase overcurrent protection: The electronics are equipped with phase overcurrent protection.
Inthis event electronics stops the motor immediately and tries to perform restart automatically.
Rotor failed acceleration: The electronics are equipped with rotor failed acceleration protection hen
the rotor is damaged or hardly rotates. Electronic automatically retries to perform 25 restarts in
1second intervals. If the 25th restarts is still unsuccessful, then manual restart by disconnecting
the power supply is required.
NOTE
Heating the controller over the maximal temperature is not allowed.
Above 105C electronics stops the motor, and restarts it again when the temperature of
controller falls below 75 C. However, if the controller is overheating and motor was shutdown,
disconnect the power supply (using safety switch) and wait at least 20 minutes before
performing any service tasks. In case of overheating of controller, the metal parts of them are
very hot and could cause serious damage to your skin.
If controller starts reducing output power during operation, this may be a reason of
overheating. Ensure air ow through the ribs/motor. Overheating problem appears in the
case of installation of the controller in the space without the proper air ow.
Verify OK
Unit is free of mechanical damage. There are no traces of rust.
There are no unwanted objects inside the casing which are not internal fan parts.
The impeller rotates without rubbing against other elements
The impeller has no undesirable vibrations during operation.
There are no unwanted objects inside the casing which are not internal fan parts.
The fan blades are not damaged, there are no cracks.
Engine wires are not damaged – no signs of mechanical damage.
