5 MAINTENANCE
5.1
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. Take
careful notice of the “Safety rules, instructions and precautionary measures” in the front of
this manual.
•
The B-SMART 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 B-SMART 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 B-SMART 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
The life-time of the battery is influenced by several issues:
•
Pulse output.
•
Analog output signal: be sure that an external power supply is connected or that the function is
disabled if not in use, as this has a major influence on the battery life-time.
•
Low temperatures; the available power will be less due to battery chemistry.
•
NPN and PNP inputs consume more energy than coil inputs.
•
High input frequency.
It is strongly advised to use only necessary functions.
Check periodically
•
The condition of the enclosure, 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 K-factor alterations.
•
The indication for low-battery. Replacement battery: see technical specifications.
•
Clean the enclosure with a lint-free cloth, soaked with a mild soap solution or fresh water.
