Wiring Startup TroubleshootingBefore You Begin Mounting

Troubleshooting

4.1 General guidelines

Troubleshooting a Micro Motion flowmeter is performed in two parts:

1. Tests of wiring integrity

2. Observation of the transmitter's diagnostic tools, which include the

diagnostic LED and fault output levels

Follow these general guidelines when troubleshooting a Micro Motion

flowmeter:

• Before beginning the diagnostic process, become familiar with this

instruction manual and with the instruction manual for the sensor.

• While troubleshooting a problem, leave the sensor in place, if possible.

Problems often result from the specific environment in which the

sensor operates.

• Check all signals under both flow and no-flow conditions. This

procedure will minimize the possibility of overlooking some causes or

symptoms.

CAUTION

During troubleshooting, the transmitter could produce

inaccurate flow signals.

For personal and system safety:

• Set control devices for manual operation while

troubleshooting the flowmeter.

• If terminal blocks are unplugged from the transmitter,

cycle power to the transmitter after reconnecting terminal

blocks.
