8 Maintenance
8.1 Exterior cleaning
When cleaning the exterior, always use cleaning agents that do not attack the surface of the housing
and the seals.
8.2 Repairs
The Hauser repair concept assumes that the measuring devices have a modular design and
that customers are able to undertake repairs themselves

information on service and spare parts, please contact your Hauser sales representative.
8.3 Repairs to Ex-approved devices
When carrying out repairs to Ex-approved devices, please note the following:
• Repairs to Ex-approved devices may only be carried out by trained personnel or by the
Hauser Service.
• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA) and
certificates.
• Only use original spare parts from Hauser.
• When ordering a spare part, please note the device designation on the nameplate. Only replace
parts with identical parts.
• Carry out repairs according to the instructions. On completion of repairs, carry our the specified
routine test on the device.
• Only Hauser Service may convert a certified device into a different certified variant.
• Document all repair work and conversions.
8.4 Replacement
After a complete instrument or electronic module has been replaced, the parameters can be
downloaded into the instrument again via the communication interface. Prerequisite to this is that
the data were uploaded to the PC beforehand using FieldCare. Measurement can continue without
having to carry out a new setup. Only a linearisation and a tank map (interference echo suppression)
have to be recorded again.
8.5 Replacing a sensor
Sensors can be replaced if required.
After replacing a sensor, the following parameters of the "basic setup" submenu must be checked:
• for sensors FDU8x: sensor type
(sensors of the type FDU9x are automatically detected by the Prosonic S)
• the empty calibration
• for level measurements: the full calibration
• the interference echo suppression
After that, the measurement can be continued without further restrictions.
