3.Determine desired meter orientation and perform either procedure A or B. Note the following when installing and positioning the short ribbon cable and when applying power to the transmitter.

NOTE

Pin 1 end of cable connector is identified by dark Red or Blue striped cable conductor. Pin 1 of Board “J” connector is identified by the “1” printed next to one corner of the connector.

At power-up, an automatic display test is performed which turns on all LCD segments for approximately 5 seconds. At the conclusion of the test, if the Transmitter is active, a numerical value will be displayed with an annunciator. If the Transmitter is configured as a Controller, additional annunciators may be displayed.

4.4.5 Electrical Conduit and Cable Installation

Electrical conduit and network, sensor, and power wire are supplied by the user. Access to electrical terminals is described in Section 4.4.5.3.

For conduit and cable routing, refer to the user's installation drawings. Installation of conduit and cabling should follow the guidelines given below.

4.4.5.1 Conduit

ŸTransmitter conduit inlets accept male conduit fittings. Refer to the Transmitter's nameplate and Section 8.1 to determine whether conduit threads are ½-14 NPT or M20 x 1.5.

Seal ½ NPT fittings with TFE/PTFE tape; seal M20 fittings with a soft-setting sealing compound rated for at least 105°C (221°F).

ŸWhen routing conduit, avoid areas that might subject the conduit to chemical or physical abuse or areas with high EMI/RFI conditions.

ŸLong sensor cable runs should be installed in conduit between the transmitter and sensor.

ŸInstall sensor cable in conduit in areas of high electrical interference.

ŸInstall conduit for field wiring.

ŸIf a high humidity environment can exist and the transmitter is located at a low point in the conduit run, install drain seals at the transmitter's conduit inlets to prevent condensation from entering the Transmitter. See Figure 4-11.

ŸRemove all sharp edges or burrs from conduit that may damage wires.
