The 4 operating modes are described here:
1 - The blower is running at a fixed speed
. Since the frequency converter
in this operating mode keeps the blower speed constant, the PID control
of the converter is not used. The blower speed unit is only rpm, so it is not
possible to select other units.
The maximum blower speed is 3.600 rpm, which is the default value of the
speed. By default, the maximum speed for the current blower is displayed,
here 3.600 rpm.
If the maximum blower speed is desired to be reduced, press the value, in
this case the 3.600, and a new smaller value can be entered.
It allows you to change the scale to other values lower than 3.600 rpm
which is the maximum on the scale. This can provide a better understand-
ing of the operator, as the blower may not be able to achieve maximum
speed, since this depends on the installation.
If the % button is selected, the speed scale will change to a % scale.
An extra line now appears at the bottom of the screen, where the ratio be-
tween 100% and speed must be defined.

2 - The blower delivers a fixed static pressure
. The pressure is meas-
ured with a pressure transducer connected to the blower control. The
maximum pressure for the blower is 16 kPa, which is the default value on
the pressure scale as seen on the right side of the screen. If you want to
change the value, press the existing value and enter a new value.
It is possible to select the pressure in kPa or inWG (inch water gauge). If
the pressure in inWG is selected, the unit on the scale changes to inWG.
16 kPa is approx. 64 inWG
It is possible to change the scale to other values lower than 16 kPa, which
is the maximum on the scale. This can provide a better understanding of
the operator, as the blower may not necessarily achieve the maximum
pressure, since this depends on the installation.
If the % button is selected, the pressure scale will change to a % scale.
An extra line now appears at the bottom of the screen, where the ratio be-
tween 100% and the pressure in kPa / inWG must be defined.
3 - The blower delivers a fixed air flow
. The air flow is measured with a
pressure transducer connected to the blower control.
The maximum airflow depends on the blower model. By default, the maxi
-
mum airflow for the current blower is displayed, here 6.000 m
3
/h.
If the maximum airflow should be reduced, the value is pressed, ie the
6.000, and a new smaller value can be entered.
It is possible to select airflow in m
3
/h or in CFM (cubic feet per minute). If
the pressure in CFM is selected, the unit on the scale switches to CFM.
6.000 m
3
/h is approx. 3.530 CFM.
It is possible to change the scale to other values lower than 6.000 m
3
/h,
which is the maximum on the scale. This can provide a better understand-
ing for the operator, as the blower may not necessarily achieve the maxi-
mum pressure, since this depends on the installation.
If the % button is selected, the flow scale will change to a % scale.
An extra line now appears at the bottom of the screen, where the ratio be-
tween 100% and the flow in m
3
/h / CFM must be defined.
