8 Maintenance and Repair
8.1 Maintenance
MaintenanceCheck the condition of the transmitter during regular inspections. If necessary, free the
antenna from build-up. When cleaning the antenna, handle with care.
ExchangeAfter the exchange of a complete Micropilot or the electronic module, the noted
parameters can be entered (e.g. download from computer) into transmitters with
communication interface or operating and display module. Measurements can then
proceed without the need for calibration.
•
If necessary, re-activate linearisation in V2H0
•
If necessary, record a new echo suppression map, see Chapter 6.3.
A new echo suppression map must be made if the antenna is exchanged.
8.2 Repairs
Should the transmitter need to be repaired by Endress+Hauser, please send it to your
nearest service station with a note containing the following information:
•
An exact description of the application for which it was used
•
The chemical and physical properties of the product measured
•
A short description of the fault.
•
If appropriate the error numbers in V9H0 and V9H1.
Warning!
Special precautions must be observed when sending the transmitters for repair:
•
Remove all traces of product.
•
This is particularly important if the product can impair health, i.e. is corrosive,
poisonous, carcinogenic, radioactive etc..
•
If the last traces of dangerous products cannot be removed, e.g. product has
penetrated into fissures or diffused into plastic parts, we kindly ask you not to
send the transmitter for repair.
Warning!
