CALIBRATION AND MAINTENANCE

UM344-2

Check that all wire connections are tight.

Enclosure threads must be coated with a wet, paste-type, anti-seize compound such as Never-Seez by Emhart Bostik. Inspect the enclosure O-ring for damage.

It is not recommended that the enclosure’s electronics module compartment be opened for inspection.

6.2.5 Transmitter Calibration

An annual calibration check should be performed to ensure that the transmitter is within specifications. Refer to Section 6.1 for details.

6.3 TROUBLESHOOTING

This Section provides guidance and procedures to assist in identifying and correcting a malfunctioning Model 344 Temperature Transmitter. Section 6.2.1 lists needed tools and equipment.

All documentation associated with the transmitter including piping and loop wiring diagrams and configuration documentation should be available to maintenance personnel to facilitate troubleshooting.

NOTE

The Moore XTC Communicator (MXC) is approved for use in non- hazardous areas only.

6.3.1 Preliminary Troubleshooting

Symptoms and messages resulting from a transmitter malfunction can expedite the troubleshooting process. Messages are displayed on an MXC screen and the optional digital meter

The following paragraphs explain the displayed messages and other visual indications that show the status of the loop or the status of the transmitter.

A. Moore XTC Communicator

Use the MXC's STATUS key to interrogate a transmitter and display a FAILSAFE message caused by a transmitter failing a self-diagnostic test. This will identify the source of error through an error message described in Table 6.1 and Section 6.3.2.1, paragraph
