Optional special versions
Information on pictograms
On the pages of the catalogue and on the following overview pages, the pictograms illustrated below provide information about technically possi-
ble special versions in the fan line presented.
Please note that these special versions are not possible for all voltages and speeds, and not in all combinations.
The special versions are designed for specific customers and projects and are not usually available off the shelf.

I
Speed signal
The fan uses a separate wire to output information
about its speed, and thus about the speed of the rotor.
For technical details, please refer to page 110.
Go / No-go alarm
The fan uses a separate wire to output a static signal
when it is stationary, thus providing information about
whether or not the rotor is turning. For technical
details, please refer to page 117.
Alarm with limit speed
If the speed drops below a certain level defined in the
fan's electronics, the fan will emit a static signal, thus
providing information about whether or not the rotor is
turning. For technical details, please refer to page 114.
External temperature sensor
An NTC is connected to the fan via a separate wire and
the fan changes its speed depending on the temperatu-
re at the NTC. For technical details, please refer to
page 120.
Internal temperature sensor
In this case, the NTC is integrated into the fan and the
fan changes its speed depending on the temperature at
the NTC. For technical details, please refer to page
120.
PWM
A
PWM control input
The speed of the fan can be changed via a pulse-width-
modulated signal. This signal is applied to a specially
provided wire. For technical details, please refer to page
121.
Analogue control input
The speed of the fan can be changed via a control volta-
ge. This control voltage is applied to a specially provided
wire. For technical details, please refer to page 121.
Multi-option control input
The fan has a control input that the user can trigger eit-
her using a PWM signal, an analogue signal or a
resistor. For technical details, please refer to page 122.
