Section 10 Warranty and liability
The manufacturer warrants that the supplied product is free of material and manufacturing
defects and undertakes to repair or replace any defective parts at zero cost to the owner.
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 any direct or indirect damages is not
accepted.
If instrument-specific maintenance and servicing work prescribed by the supplier is to be
performed within the warranty period by the customer (maintenance) or by the supplier
(servicing) and these requirements are not met, claims for damages resulting from
non-compliance with these requirements are rendered 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.
