12 Troubleshooting
12.1

Introduction

This section covers basic transmitter and sensor troubleshooting. Problems in the
magnetic flow meter system are usually indicated by incorrect output readings from the
system, error messages, or failed tests. Consider all sources when identifying a problem in
the system. If the problem persists, consult an Emerson Flow Representative (see back
page) to determine if the material should be returned to the factory. Emerson 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. Read the following safety messages before performing any
operation described in this section. Refer to these warnings when appropriate throughout
this section.
The transmitter performs self-diagnostics on the entire magnetic flow meter system: the
transmitter, the sensor, and the interconnecting wiring. By sequentially troubleshooting
each individual piece of the system, it becomes easier to identify the problem and make
the appropriate adjustments.
If there are problems with a new installation, see
quick guide to solve the most common problems. For existing installations, lists the most
common problems and corrective actions.
