1) Holding torque (not under power) due to self-locking in transmission system 1 Nm
2) Non-connected analogue inputs are valued at 0 V. The nominal torque is attained within the given tolerances. AI/AO can be used only as an input.
3) Holding torque > 10 Nm
4) Running time can be set via the software
5) Maximum angle of rotation 95° (without end stop)
6) Brief overload; the sensor's zero-point adjustment is recommended
7) Recommend hardness of tubes < 40 Sha (e.g. silicone)
8) Connection 02 can be configured as an analogue input or analogue output using SAUTER CASE VAV software
9) Digital inputs for external potential-free contacts (gold-plated recommended)
10) The parametering tool is always one of the subscribers, so a maximum of 31 devices can be linked

General description of operation
The differential pressure created on an orifice plate or a dynamic
pressure sensor is recorded by a static differential pressure sensor
and is converted into a flow-linear signal. An external command
signal c
q
is limited by the parameterised minimum and maximum
settings, and is compared with the actual air volume r
q
. Based on
the control deviation that is determined, the damper on the air
volume box is adjusted by the drive until the required air volume is
attained over the measurement point. Without an external com-
mand signal, the value for
min
that was specified in the parame-
terisation corresponds to command variable c
q
Configuration of the
application and the internal parameters is software-based, using
SAUTER CASE VAV PC software.
The software supports the application-specific configuration of the
compact controller and the setting of the necessary parameters in
bus mode. The VAV compact controller is supplied ex factory with a
standard configuration. For this purpose, the inputs and outputs are
preconfigured as shown in the table.
