INSTALLATION

ŸDetermine conduit routing. Refer to Section 4.4.5.

ŸPrepare installation site drawings showing the following:

ŸLocation of the Master Device (e.g. MXC or controller)

ŸLocation and identification of each Transmitter

ŸRouting plan of signal cable(s)

ŸLocation of any signal cable junctions for connecting the MXC

4.3.2 Electrical

ŸDetermine Transmitter operating mode (analog or digital) and type of Network needed; refer to Section 4.3.3.

ŸDetermine minimum power supply requirements. Refer to Section 4.3.4.

ŸSelect twinaxial cable type and determine maximum cable length. Refer to Section 4.3.5.

ŸDetermine the need for network junctions. Refer to Section 4.3.6.

ŸIntrinsically Safe installations will need barriers. Refer to Section 4.3.7.

ŸConsider the effect of connecting additional equipment (e.g., recorder, loop powered display) to the network. Refer to Section 4.3.8.

∙Select sensor cable type. Refer to Section 4.3.9.

∙Consider the accuracy limitation of a 2-wire RTD. Refer to Section 4.3.10.

∙Read Section 4.3.11 for grounding and shielding recommendations.

4.3.3 Transmitter Operating Mode and Network Type

A Transmitter will output either an analog current or an equivalent digital signal, depending upon the selected operating mode. The operating mode also determines the type of Network (Point-To-Point or Multi-Drop) to be installed, as shown in Table 4.1 and the following subsections. Select the operating mode during Transmitter configuration as described in the following subsections and Section 5.
