Prerequisites

For mounting the remote core processor to a wall:

• Micro Motion recommends the use of 5/16-18 (8 mm–1.25) fasteners that can

withstand the process environment. Micro Motion does not supply bolts or nuts as
part of the standard offering (general purpose bolts and nuts are available as an
option).

• Ensure that the surface is flat and rigid, does not vibrate, or move excessively.

• Confirm that you have the necessary tools, and the mounting kit shipped with the

transmitter.

For mounting the remote core processor to an instrument pole:

• Use two 5/16-inch U-bolts for 2-inch pipe, and four matching nuts, that can

withstand the process environment. Micro Motion does not supply U-bolts or nuts.

3.5.1 9-wire cable types and usage

Cable types

Micro Motion supplies three types of 9-wire cable: jacketed, shielded, and armored. Note
the following differences between the cable types:

• Armored cable provides mechanical protection for the cable wires.

• Jacketed cable has a smaller bend radius than shielded or armored cable.

• If ATEX compliance is required, the different cable types have different installation

requirements.

Cable jacket types

All cable types can be ordered with a PVC jacket or Teflon® FEP jacket. Teflon FEP is
required for the following installation types:

• All installations that include a T-series sensor.

• All installations with a cable length of 250 ft (75 m) or greater, a nominal flow less

than 20 percent, and ambient temperature changes greater than +68 °F (+20 °C).

Mounting and sensor wiring for remote core processor with remote sensor installations

3.6 Wire the remote core processor to the sensor using jacketed cable

Prerequisites

For ATEX installations, the jacketed cable must be installed inside a user-supplied sealed
metallic conduit that provides 360° termination shielding for the enclosed cable.

CAUTION!

Sensor wiring is intrinsically safe. To keep sensor wiring intrinsically safe, keep the sensor
wiring separated from power supply wiring and output wiring.

CAUTION!

Keep cable away from devices such as transformers, motors, and power lines, which produce
large magnetic fields. Improper installation of cable, cable gland, or conduit could cause
inaccurate measurements or flow meter failure.

CAUTION!

Improperly sealed housings can expose electronics to moisture, which can cause measurement
error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and
grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.

Procedure

1. Run the cable through the conduit. Do not install 9-wire cable and power cable in

the same conduit.

2. To prevent conduit connectors from seizing in the threads of the conduit openings,

apply a conductive anti-galling compound to the threads, or wrap threads with PTFE
tape two to three layers deep.

Wrap the tape in the opposite direction that the male threads will turn when
inserted into the female conduit opening.

3. Remove the junction box cover and core processor end-cap.

4. At both the sensor and transmitter, do the following:

a. Connect a male conduit connector and waterproof seal to the conduit opening

for 9-wire.

b. Pass the cable through the conduit opening for the 9-wire cable.

c. Insert the stripped end of each wire into the corresponding terminal at the

sensor and transmitter ends, matching by color. No bare wires should remain
exposed.

3.7 Wire the remote core processor to the sensor using shielded or armored cable

Prerequisites

For ATEX installations, shielded or armored cable must be installed with cable glands, at
both the sensor and remote core processor ends. Cable glands that meet ATEX
requirements can be purchased from Micro Motion. Cable glands from other vendors can
be used.

CAUTION!

Keep cable away from devices such as transformers, motors, and power lines, which produce
large magnetic fields. Improper installation of cable, cable gland, or conduit could cause
inaccurate measurements or flow meter failure.

CAUTION!

Install cable glands in the 9-wire conduit opening in the transmitter housing and the sensor
junction box. Ensure that the cable drain wires and shields do not make contact with the
junction box or the transmitter housing. Improper installation of cable or cable glands could
cause inaccurate measurements or flow meter failure.

Mounting and sensor wiring for remote core processor with remote sensor installations

Prerequisites

CAUTION!

Improper grounding could cause inaccurate measurements or meter failure.

Note

For hazardous area installations in Europe, refer to standard EN 60079-14 or national standards.

If national standards are not in effect, adhere to the following guidelines for grounding:

• Use copper wire, 14 AWG (2.5 mm2) or larger wire size.

• Keep all ground leads as short as possible, less than 1 Ω impedance.

• Connect ground leads directly to earth, or follow plant standards.

Procedure

1. Ground the sensor according to the instructions in the sensor documentation.

2. Ground the DIN rail.

The rail clip in the base of the transmitter housing grounds the transmitter to the
DIN rail.

3. Ground the remote core processor according to applicable local standards, using

the remote core processor’s internal ground screw.

Description

Three input/output channels (A, B, and C) that can be configured from the following choices:

• One or two active 4–20 mA outputs (Channels A and B):

- Not intrinsically safe

- Isolated to ±50 VDC from all other outputs and earth ground

- Maximum load limits of mA1: 820 ohms; of mA2: 420 ohms

- Can report mass flow, volume flow, density, temperature, or drive gain

- Output is linear with process from 3.8 to 20.5 mA, per NAMUR NE43 Version 03.02.2003

• One or two active or passive frequency/pulse outputs (Channels B and C):

- Not intrinsically safe

- Can report mass flow or volume flow, which can be used to indicate flow rate or total

- If configured as a dual pulse output, the channels are electrically isolated but not independ-
