ST 800 SmartLine Pressure Transmitter Honeywell

Quick Installation Card

Know your Transmitter The transmitter can measure the differential, absolute and gauge pressures which can be communicated in Fieldbus,

HART Version 7, and Digitally Enhanced protocols in process engineering. It has meter body and electronic housing

assemblies which can easily assembled in your process. The following figure shows the flange type connection of the

transmitter.

Troubleshooting Fault Conditions and Recommended Corrective Actions

Condition Analysis Recommended Corrective Action

Meterbody fault. A critical failure has been detected in the Meterbody

Use a HART, DE, or FF communicator to read the detailed status information

from the transmitter. Refer to the appropriate communicator

manual to get more information about the possible

causes of the failure.

Cycle power to the Transmitter. If the problem continues to occur, replace

the Meterbody.

Electronics Module Fault. A critical failure has been

detected on the HART, DE, or FF Electronics Module.

Use a HART, DE, or FF communicator to read the detailed status information

from the transmitter. Refer to the appropriate communicator manual for more information

about the possible failure causes.

Cycle power to the transmitter.

If the problem continues to occur replace the Electronics

Module.

Meterbody Comm fault. .

This could be the result of a failure on either of these modules or the cable that

connects them.

Check the ribbon cable that connects the Meterbody to

the Electronics Module. Make sure that the cable is securely plugged into the Electronics Module. Make sure that all pins are plugged into the

connector (i.e., make sure that the connector is not

offset in a way that leaves some pins unconnected).

Communications between the Meterbody and the

Electronics Module has failed

Use a HART, DE, or FF communicator to read the detailed status information

from the transmitter. Refer to the appropriate communicator

manual to get more information about the possible

causes of the failure.

Cycle power to the transmitter.

If the problem continues to occur replace the Electronics Module. If this does not fix the

problem, replace the Meterbody.
