Chapter 5 - Maintenance and Troubleshooting

of the Electromagnetic Flowmeter

Outline of this
chapter

This chapter describes the maintenance and inspection procedures for the
electromagnetic flowmeter and the information that should be referred to dur-
ing troubleshooting.

First, this chapter explains the procedures used to check the converter func-
tions. The items to be checked are as follows.

• Input/output signal loop check

Analog output
Pulse output
Contact input/output
Excitation current

• False signal input by the calibrator

These items serve to aid in early detection of the causes of abnormalities in
converter operation.

This chapter also explains the troubleshooting procedures and the initial data
recovery procedures.

When using the S-SFC (either Japanese or English display) refer to the user’s
manual CM2-MGG000-2001.
