This section covers basic transmitter and sensor troubleshooting. Problems in
the magnetic flowmeter system are usually indicated by incorrect output
readings from the system, error messages, or failed tests. Consider all
sources when identifying a problem in your system. If the problem persists,
consult your local Rosemount representative to determine if the material
should be returned to the factory. Emerson Process Management offers
several diagnostics that aid in the troubleshooting process.
Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please read the
following safety messages before performing any operation described in this
section. Refer to these warnings when appropriate throughout this section.
SAFETY INFORMATION
The 8732 performs self diagnostics on the entire magnetic flowmeter system:
the transmitter, the sensor, and the interconnecting wiring. By sequentially
troubleshooting each individual piece of the magmeter system, it becomes
easier to pin point the problem and make the appropriate adjustments.
If there are problems with a new magmeter installation, see “Installation
Check and Guide” on page 6-2 for a quick guide to solve the most common
installation problems. For existing magmeter installations, Table 6-4 lists the
most common magmeter problems and corrective actions.
Failure to follow these installation guidelines could result in death or serious injury:
Installation and servicing instructions are for use by qualified personnel only. Do not perform
any servicing other than that contained in the operating instructions, unless qualified. Verify
that the operating environment of the sensor and transmitter is consistent with the
appropriate FM or CSA approval.
Do not connect a Rosemount 8732 to a non-Rosemount sensor that is located in an
explosive atmosphere.
Mishandling products exposed to a hazardous substance may result in death or serious
injury. If the product being returned was exposed to a hazardous substance as defined by
OSHA, a copy of the required Material Safety Data Sheet (MSDS) for each hazardous
substance identified must be included with the returned goods.
