6 MAINTENANCE
6.1 GENERAL DIRECTIONS
•
Mounting, electrical installation, start-up and maintenance of the instrument may only be
carried out by trained personnel authorized by the operator of the facility. Personnel must
read and understand this Operating Manual before carrying out its instructions.
•
The F011-A may only be operated by personnel who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
•
Ensure that the measuring system is correctly wired up according to the wiring diagrams.
The housing may only be opened by trained personnel.
•
Take careful notice of the
“Safety rules, instructions and precautionary measures” in the
front of this manual.
The F011-A does not require special maintenance unless it is used in low-temperature applications
or surroundings with high humidity (above 90% annual mean). It is the users responsibility to take all
precautions to dehumidify the internal atmosphere of the F011-A in such a way that no condensation
will occur, for example by placing dry silica-gel sachet in the casing just before closing it.
Furthermore, it is required to replace or dry the silica gel periodically as advised by the silica gel
supplier.
Battery life-time:
It is strongly advised to use only necessary functions.
It is influenced by several issues :
•
Display update: fast display update uses significantly more power.
•
Pulse output.
•
Low temperatures; the available power will be less due to battery chemistry.
Check periodically:
•
The condition of the casing, cable glands and front panel.
•
The input/output wiring for reliability and aging symptoms.
•
The process accuracy. As a result of wear and tear, re-calibration of the flowmeter might be
necessary. Do not forget to re-enter any subsequent Span alterations.
•
The indication for low-battery.
•
Clean the casing with soapy-water. Do not use any aggressive solvents as these might damage
the coating.
