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 enclosures 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 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
The voltage outputs are short-circuit proof against earth. The device is
destroyed if voltage supply is applied to the voltage output.
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.
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!
POTENTIOMETER
To compensate for different installation heights, two stub axles are provided for the potentiometer, depending on the switch programme.
This is to ensure that the minimum and maximum stops of the potentiometer function properly.
