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.
