6.0 MAINTENANCE

6.1 General

Except for an occasional performance verification check, there is no required routine maintenance for
the Series 3000 Magnetic Flowmeter. For practical reasons it is suggested that the meter body not be
disassembled. If disassembled, complete waterproof sealing is required for satisfactory operation
and is best done at the factory. Replacement of faulty magnet drive coils and electrode replacement
is a factory operation. Factory calibration after this type of repair is the only way to guarantee meter
accuracy.
ABB Automation offers a Repair/Exchange Program to facilitate replacement of a defective meter or
Converter. If the equipment is beyond the warranty limit, under this program a fixed price will be
charged for replacement of defective equipment, with appropriate credit issued when the repairable
unit is received by ABB Automation (charges prepaid). The equipment available under this program
is as follows:
• the complete meter including remote Signal Converter
• the meter and associated primary board; that is, the hydraulic portion without the
Signal Converter
• the remote Signal Converter
All Flowmeters and/or Signal Converters being returned to ABB
Automation for repair must be free of any hazardous materials (acids,
alkalis, solvents, etc.). A Material Safety Data Sheet (MSDS) for all
process liquids must accompany returned equipment. Contact ABB
Automation for authorization prior to returning equipment.
Operation and maintenance procedures for the Signal Converter
are provided in the Instruction Bulletin supplied with the Signal Con-
When communicating with ABB Automation regarding replacement of a complete meter (including
the Converter), the meter body, or the Signal Converter, it is important to refer to the complete
instrument serial number to assure that the correct replacement will be supplied. This information is
provided on the manufacturing specification sheet supplied with the Magnetic Flowmeter, and on the
instrument data tag.
Some of the IC devices used in the Signal Converter are static sensitive
and may be damaged by improper handling. When adjusting or
servicing the Signal Converter, use of a grounded wrist strap is
recommended to prevent inadvertant damage to the integral solid state
