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. Installation of these devices must only be realized by
authorized qualified personnel. 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 products. 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 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 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 installation:
Mounting shall take place while observing all relevant regulations and
standards applicable for the place of measurement (e.g. such as weld-
ing 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
– Installation length, tube dimensions
– Oscillations, vibrations, shocks are to be avoided (< 0.5 g)
Attention! In any case, please observe the mechanical and ther-
mal load limits of the protective tubes according to DIN 43763
or according to specific S+S standards!
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!
