General information on repairs

12.1.1

Repair concept

The Endress+Hauser repair concept assumes that the devices have a modular design and that
repairs can be done by the Endress+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 Endress
+Hauser.

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 Endress
+Hauser Service.
• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA) and
certificates.
• Only use original spare parts from Endress+Hauser.
• When ordering a spare part, please note the device designation on the nameplate. Only replace
parts with identical parts.

12.1.3

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).
12.1.4

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
(® ä 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.
