1 General notes
1.1 Structure of the operating instructions
Before installation and start-up, read this manual carefully to
ensure correct use!
We emphasize that these operating instructions apply to specific
units only, and are in no way valid for the complete system!
Use these operating instructions to work safely with and on the
device. They contain safety instructions that must be complied
with as well as information that is required for failure-free operation
of the device.
Keep these operating insturctions together with the device. It must
be ensured that all persons that are to work on the device can
refer to the operating instructions at any time.
1.2 Target group
The operating instructions address persons entrusted with planning, installation, commissioning and maintenance and servicing
and who have the corresponding qualifications and skills for their
job.
1.3 Exclusion of liability
To allow for future developments, construction methods and technical data given are subject to alteration. We do not accept any
liability for possible errors or omissions in the information contained in data, illustrations or drawings provided.
We accept no liability for damage caused by misuse, incorrect
use, improper use or as a consequence of unauthorized repairs or
modifications.
1.4 Copyright
These operating instructions contain copyright protected information. The operating instructions may be neither completely nor
partially photocopied, reproduced, translated or put on data medium without previous explicit consent. Infringements are liable for

damages. All rights reserved, including those that arise through
patent issue or registration on a utility model.
2 Safety instructions
•
Mounting, electrical connection, and start-up operation may only
be carried out by an electrical specialist in accordance with
electrotechnical regulations (e.g. DIN EN 50110 or
DIN EN 60204)!
•
Persons entrusted with the planning, installation, commissioning
and maintenance and servicing in connection with the device
must have the corresponding qualifications and skills for these
jobs. In addition, they must be knowledgeable about the safety
regulations, EU directives, rules for the prevention of accidents
and the corresponding national as well as regional and in-house
regulations.
•
The equipment is to be used solely for the purposes specified
and confirmed in the order. Other uses which do not coincide
with, or which exceed those specified will be deemed unauthorised unless contractually agreed. Damages resulting from such
unauthorised uses will not be the liability of the manufacturer.
The user will assume sole liability.
•
It is strictly forbidden for work to be carried out on any components while they are connected to live voltage.
•
The safe isolation from the supply must be checked using a twopole voltage detector.
•
The owner is obliged to ensure that the device is operated in
perfect working order only.
•
Inspect electrical equipment periodically: retighten loose connections – immediately replace damaged lines and cables.
•
Never clean electrical equipment with water or similar liquids.
•
A separate fault and performance monitoring-system with an
alarm signal function is necessary in order to prevent personal
injuries and material damages during malfunctions and in case
the device fails. Substitute operation must be taken into consideration!

3 Product overview
3.1 Operational area
Pressure and volume control for ventilation systems.
Depending on the programmed Mode the device can be used
as sensor or as a control module for pressure or volume.
•
For operation as pressure sensor the device supplies an output
signal (0 - 10 V) proportional to the measuring range.
•
For operation as air volume sensor the device supplies an output signal (0 - 10 V) proportional to the air volume measuring
range (
INFO / Range qV). Function in combination with
centrifugal fans and measuring device in the inlet ring. The
controller calculates the air volume of the fan from the “K-Factor”
differential between the suction side and the inlet duct.
•
For operation as control module for pressure or volume the
purpose of the device is to reach and maintain the target value
set. To accomplish this, the measured actual value (sensor
value) is compared with the adjusted target value, and the controlled value is deduced from this. Controlled output (0 - 10 V)
e.g. for activating a speed controller for fans or an EC-fan
directly.
3.2 Function
Sensor with a membrane system suitable for measuring differential or negative pressure of non-aggressive gas.
The differential pressure to be measured takes effect on a spring
supported silicone membrane.
Changes in position of the membrane are detected by a differential
transformer and converted into an output signal of 0 - 10 V by an
electronics unit.
Function when the pressure at the “Plus”- connection exceeds the
pressure at the “Minus”- connection.
