Installation and Commissioning
Devices are to be connected under dead-voltage condition. Devices must
only be connected to safety extra-low voltage. 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 shown on the
device labels and in 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
pro ducts. In case of any modifications made by the user, all warranty
claims are forfeited. 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 housing 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.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and
standards applicable for the place of measurement (e.g. such as welding
instructions, etc.). Particularly the following shall be regarded:
– VDE ⁄ VDI directive technical temperature measurements, measurement
set - up for temperature measurements.
– The EMC directives must be adhered to.
– It is imperative to avoid parallel laying of current-carrying lines.
– We recommend to use shielded cables with the shielding being
attached at one side to the DDC ⁄ PLC.
Before mounting, make sure that the existing thermometer‘s technical
parameters comply with the actual conditions at the place of utilization,
in particular in respect of:
– Measuring range
– Permissible maximum pressure, flow velocity
– Oscillations, vibrations, shocks are to be avoided (< 0.5 g)
CONNECTING CONDITIONS
Output: 0 - 10 V
The output voltage follows linear to the temperature signal applied at
the input terminals and generates a proportional output signal of 0 - 10 V.
The voltage outputs are short-circuit proof against ground wire. Applying
voltage supply to the output terminals will destroy the device.
Output: 4 ... 20 mA
In case of the 4 ... 20 mA measuring transducer, display and evaluating
elements are connected in series in the current loop. The measuring
transducer thereby liWiths the flowing current in variance of the
input signal. 4 mA are for the measuring transducer‘s internal current
consumption. The apparent ohmic resistance can either be connected in
the plus or minus path of the measuring transducer. In case of an apparent
ohmic resistance in the plus path, power supply and resist.
SAFETY REGULATIONS
These devices shall only be used for their 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
buyer has to ensure adherence to the building and safety regulations and
has to avoid all dangers of any kind. We do not assume any warranty for
faults or damages arising or resulting from improper use of our equipment
or from non-observance of operating instructions. These instruments
must be installed by authorised specialists only!
Preferably shielded cables should be used in order to prevent damages ⁄
errors. It is imperative to avoid laying parallel with current-
carrying lines. EMC directives must be adhered to.

General notes
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
