General notes
– The sensor is mounted inside the enclosure cover. Make sure not to damage the cable ⁄ sensor when opening enclosure.
– If necessary for mounting and ⁄ or electric wiring, unplug connector carefully and
plug it back on again in the same position after mounting and electric wiring.
– Protect sensor surface against any kind of dirt and ⁄ or damage.
– Scratches, dirt, and also partial shading falsify the measuring result.
– Applying overvoltage will destroy the device.
– 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 additionIn 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 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 improve-
ment 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 solely 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!
SUPPLY VOLTAGE:
For operating voltage reverse polarity protection, a one-way rectifier or
reverse polarity protection diode is integrated in this device variant.
This internal one-way rectifier also allows operating 0 - 10 V devices on AC
supply voltage.
The output signal is to be tapped by a measuring instrument. Output volt-
age is measured her against zero potential (O V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage
input UB+ is to be used for 15...36 V DC supply and UB – or GND for ground
wire!
When several devices are supplied by one 24 V AC voltage supply, it is to
be ensured that all "positive" operating voltage input terminals (+) of the
field devices are connected with each other and all "negative" operating
voltage input terminals (–) (= reference potential) are connected together
(in-phase connection of field devices). All outputs of field devices must be
referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short-
circuit would be caused by that device. The consequential short-circuit
current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
