UM344-2

INITIAL TRANSMITTER SET-UP

3.0 INITIAL TRANSMITTER SET-UP

Before operating a Model 344 on-line, the instrument should be commissioned using the MXC and set-up either at the bench or in the field. Commissioning consists of checking that the transmitter and the loop are operational and that all configuration information is correct. This section contains step-by-step procedures describing commissioning of the transmitter. For an in-depth discussion of transmitter configuration, refer to Section 5.1 On-Line Operation.

3.1 COMMISSIONING TRANSMITTER ON THE BENCH OR IN THE FIELD

A Model 344 can be commissioned either before or after installation into the loop. Commissioning on the bench before installation is suggested. A complete transmitter functional test can be performed and configuration procedures can be practiced. If commissioning after installation, install the transmitter as described in Section 4 and then return to this section. Configuration data for the transmitter will be needed.

To commission the transmitter on the bench, make the connections shown in Figure 3-1. To commission the transmitter in the field, make the connections shown in Figure 3-2 or those shown in Section 4.3.3, Figure 4-1, 4-2, or 4-3. Connect the MXC in the loop either across the current sense resistor or, often more conveniently, across the two signal terminals of the Model 344 (non-hazardous area only).
