15.1 General information on repairs
15.1.1 Repair concept
The Hauser repair concept assumes that the devices have a modular design and
that repairs can be done by the Hauser service or specially trained customers.
Spare parts are contained in suitable kits. They contain the related replacement
instructions.
For more information on service and spare parts, contact the Service Department at
Hauser.
15.1.2 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 out 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.
15.1.3 Replacement of an electronics module
If an electronics module has been replaced, it is not necessary to perform a new basic setup
as the calibration parameters are stored in the HistoROM which is located in the housing.
However, after exchanging the main electronics module it may be necessary to record a
new mapping (interference echo suppression).
15.1.4 Replacement of a device
After a complete device or electronic module has been replaced, the parameters can be
downloaded into the instrument again in one of the following ways:
• Via the display module
Condition: The configuration of the old device has been saved in the display module
→  168.
• Via FieldCare
Condition: The configuration of the old device has been saved to the computer via
FieldCare.
You can continue to measure without carrying out a new setup. Only a linearization and a
tank map (interference echo suppression) have to be recorded again.
