General notes
This device can be mounted in any position. Pressure ranges (measuring ranges) are indicated on the device label. Applying measuring pressures beyond
that range will cause mismeasurements and increased deviations or may destroy the pressure measuring transducer.
– Attention! When leading in cables, make sure, they do not go under the board.
This might buckle or damage hose connections!
– Pressure inputs are "poled" i.e. the above-atmospheric pressure line must be connected at input P+
and the below-atmospheric pressure line must be connected at input P–.
– At an adjusting element, the output signal can be offset by ± 10 % of the final value of the measuring range.
In this way, possible ageing or drift effects can be compensated.
– Adjustment may only be made at the presence of differential pressure (ca. 90 % of final value).
– By changing the offset at the adjusting element, factory-calibration is lost!
– If this device is operated beyond the specified range, all warranty claims are forfeited.
Our "General Terms and Conditions for Business" together with the "General Conditions for the Supply of Products and Services of the Electrical and
Electronics Industry" (ZVEI conditions) including supplementary clause "Extended Retention of Title" apply as the exclusive terms and conditions.
In addition, the following points are to be observed:
– Devices must only be connected to safety extra-low voltage and under dead-voltage condition. To avoid damages and errors at the device
(e.g. by voltage induction) shielded cables are to be used, laying parallel with current-carrying lines is to be avoided, and EMC directives are to be
observed.
– This device shall only be used for its intended purpose. Respective safety regulations issued by the VDE, the states, their control authorities, the
TÜV and the local energy supply company must be observed. The purchaser has to adhere to the building and safety regulations and has to prevent
perils of any kind.
– No warranties or liabilities will be assumed for defects and damages arising from improper use of this device.
– Consequential damages caused by a fault in this device are excluded from warranty or liability.
– These devices must be installed by authorised specialists only.
– The technical data and connecting conditions of the mounting and operating instructions delivered together with the device are exclusively valid.
Deviations from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous
improvement of our products.
– In case of any modifications made by the user, all warranty claims are forfeited.
– This device must not be installed close to heat sources (e.g. radiators) or be exposed to their heat flow. Direct sun irradiation or heat irradiation
by similar sources (powerful lamps, halogen spotlights) must absolutely be avoided.
– Operating this device close to other devices that do not comply with EMC directives may influence functionality.
– This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury,
or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes.
– Dimensions of enclosures or enclosure accessories may show slight tolerances on the specifications provided in these instructions.
– Modifications of these records are not permitted.
– In case of a complaint, only complete devices returned in original packing will be accepted.
These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!
