Appendix A

Troubleshooting

This appendix will help to identify and correct some of the common

problems encountered when installing or operating the IZMSG Compact

Flowmeter.
Many problems are caused when making electrical connections. Refer to

Section 3 and make sure that the connection cables are properly and securely

installed. Check the installation diagrams. Test the connection of each wire

by gently tugging the wire with needle nose pliers to ensure that the wire is

fully engaged in its terminal. Make sure that AC power is available to the

converter and that the jumpers on the power supply board are configured for

the voltage supply provided.
The appendix provides:

information on troubleshooting the converter

information on troubleshooting the meter body

procedure for performing a Dry Meter Body Resistance Check

information on Zero Test troubleshooting

error diagnosis with LCD display

hardware test sequence
