OVERVIEW

Table 5-1 provides summarized maintenance and troubleshooting
suggestions for the most common operating problems.

If you suspect malfunction despite the absence of any diagnostic messages
on the HART Communicator display, follow the procedures described here to
verify that transmitter hardware and process connections are in good working
order. Always deal with the most likely checkpoints first.

SAFETY MESSAGES

Procedures and instructions in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Refer to
the following safety messages before performing an operation preceded by
this symbol.

Warnings

Explosions can result in death or serious injury.

• Transmitters located in hazardous areas should be installed in accordance with

local codes and requirements for that area.

• Verify that the operating atmosphere of the transmitter is consistent with the

appropriate hazardous locations certifications.

Static electricity can damage sensitive components.

• Observe safe handling precautions for static-sensitive components.
