The HMI starts the installation wizard.
• Complete the installation wizard.
Refer to paragraph 5.3 and 5.3.1 for more
information about the VFD (frequency inverter) and
the PID setpoint.
Select the question mark on the touch
screen for extensive explanation on all
settings.

5.2 Extraction fan
• Turn the main switch (refer to Fig. 6.1F) to “ off ” and open
the Panel.
• Turn the bar that is connected to the main switch to
energize the Panel manually.
• Push the START/STOP FAN button (refer to Fig. 6.1F) to
start the fan.
• Make sure that the direction of rotation of the motor is
correct.
If the direction of rotation of the motor is not correct:
• Invert any two connections (96/97/98) on the VFD to
change the motor direction.
• Push the button again to stop the fan.
5.3 VFD (frequency inverter)
The VFD is integrated in the Panel. The fan speed is controlled
by the system pressure. To operate the system, you must
know or determine the airflow in the duct that is necessary to
get the correct throw and air circulation.
The required system pressure must be programmed in the HMI
to keep the airflow at a constant level, independently from the
(increasing) pressure drop caused by the filter cartridges. This
system pressure is called the ‘PID setpoint’, which arranges
the necessary fan speed (Hz) accordingly.
The table below indicates the throw related to the airflow and
fan speed

For more detailed information, refer to Fig. X on page 31.
Fig. XI shows the horizontal throw per nozzle.
5.3.1 PID setpoint of the fan pressure
To determine and set the PID setpoint, do the following.
• Go to the Settings menu on the HMI.
• Enter PIN.
Fig. 5.1
• Select menu PID setpoint of the fan pressure (or enter
2.2.1 on the numeric keypad).
25. All nozzles 100% open
• Select the button Start fan .
• Measure the actual airflow with a flowmeter. Best
measuring position: approx. 500 mm (20 in.) below the
outlet unit of the MDB-Diluter.
• Use the buttons + or ─ to determine the setpoint to reach
the desired airflow. At this setpoint, the frequency must
not exceed 45Hz.
• Select Stop fan when the desired airflow is reached.
• Select Finish to exit the screen. The new values will be
saved.
