“Troubleshooting Tables” on page 5-2 provides summarized troubleshooting
suggestions for the most common problems that occur during operation. The
symptoms of metering problems include:
• Communications problems with a HART-based communicator.
• Incorrect 4–20 mA output.
• Incorrect pulse output.
• Error messages on HART-based communicator.
• Flow in pipe but no transmitter output.
• Flow in pipe with incorrect transmitter output.
• Output with no actual flow.
NOTE
The Rosemount 8800D sensor is extremely reliable and should not have to be
replaced. Please consult the factory before removing the sensor.
SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please refer to
the following safety messages before performing any in this section.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover or thermocouple (MTA option only) from
the electronics housing in explosive atmospheres when the circuit is alive.
• Before connecting a HART-based communicator in an explosive atmosphere,
make sure the instruments in the loop are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet explosion-proof
requirements.
