Warranty
The manufacturer warrants that the supplied product is free of material and manufacturing defects,
and undertakes to repair or to replace any defective parts without charge.
The warranty period is 24 months. If a maintenance contract is taken out within 6 months of
purchase, the warranty period is extended to 60 months.
With the exclusion of further claims, the supplier is liable for defects, including the lack of assured
properties, as follows: all parts that, within the warranty period calculated from the day of the transfer
of risk, can be demonstrated to have become unusable or that can only be used with significant
limitations owing to circumstances prior to transfer of risk, in particular due to incorrect design,
substandard materials or inadequate finish, shall be repaired or replaced at the supplier's discretion.
The identification of such defects must be reported to the supplier in writing as soon as possible, but
no later than 7 days after the discovery of the fault. If the customer fails to notify the supplier, the
product is considered approved despite the defect. Further liability for indirect or direct damages is
not accepted.
If device-specific maintenance- or inspection work prescribed by the supplier is to be performed
within the guarantee period by the customer (maintenance) or by the supplier (inspection) and these
requirements are not met, claims for damages that result from non-observance of these requirements
are void.
Further claims, in particular for consequential damages, cannot be made.
Wear and damage caused by improper handling, incorrect installation or non-designated use are
excluded from this clause.
The process instruments of the manufacturer have proven their reliability in many applications and
are therefore often used in automatic control loops to enable the most economical and efficient
operation of the relevant process.
To avoid or limit consequential damage, it is therefore recommended that the control loop be
designed such that an instrument malfunction results in an automatic changeover to the backup
control system. This guarantees the safest operating condition both for the environment and the
process.
PROGNOSYS register
Table 4 shows PROGNOSYS parameters that are available from the RTC/PROGNOSYS
communication card. These parameters can be sent to a superordinate programmable open loop
control or to a computer via a fieldbus card such as Profibus or Modbus TCP/IP.
Each communication card gives parameters for a maximum of 15 sensors. The sequence for the
sensors or allocation of sensor parameters is controlled by the allocation of the sensors on the
applicable communication card. Refer to
Add a sensor on page 5.
