General notes
– This unit must only be used in non-precipitating air at the sensor element.
– With outdoor and duct sensors, the sinter filter of the sensor element protects the humidity sensor against potential dust exposure.
In case of contamination/soiling, this filter should be cleaned on a regular basis.
– Dust and contamination distort measurement results and are to be avoided.
Small amounts of contamination and dust deposits can be removed using compressed air.
– Touching the humidity element must be avoided under any circumstances, since this would result in serious measuring errors.
– In case of contamination, we recommend cleaning and recalibration in the factory.
– Under no circumstances should the sensor come into contact with chemicals or other cleaning agents.
– The relative humidity of 0...100 % is represented by the output signal of 0 - 10 V or 4... 20 mA.
The operating range of the unit covers 10 ... 99% RH outside that range, faulty measurements or increased deviations may occur.
– When several sensors (0 - 10 V)are connected to one voltage supply of 24 V AC (alternating voltage),
the correct polarity must be ensured as otherwise the alternating voltage source may be short-circuited.
– The voltage outputs are short-circuit proof. Applying overvoltage or voltage supply to the voltage output will destroy the unit.
– If this unit is operated outside 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:
– These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!
– 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 and commissioned by authorised specialists.
– 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 housings or housing 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.
Notes on commissioning:
This device was calibrated, adjusted and tested under standardised conditions. When operating under deviating conditions,
we recommend performing an initial manual adjustment on-site during commissioning and subsequently at regular intervals.
Commissioning is mandatory and may only be performed by qualified personnel!
These instructions must be read before installation and commissioning and all notes provided therein are to be regarded!
