4.2 Prepare the 9-wire cable
Micro Motion supplies three types of 9-wire cable: jacketed, shielded, and armored. The
type of cable you are using determines how you will prepare the cable.
4.2.1 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 (76.20 m) or greater, a nominal flow less
than 20 percent, and ambient temperature changes greater than 68 °F (20.0 °C).

40 Micro Motion 1700 and 2700 Transmitters
Page 41
Installation Manual Wiring the transmitter to the sensor
20001700 December 2019
NOTICE
• 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.
• 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.

5.4 Wire the remote core processor to the sensor using shielded or armored cable (9-wire)
Use this procedure to wire the remote core processor to the sensor using shielded or
armored cable in a 9-wire remote sensor installation.
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.
NOTICE
• 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.
• 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.

9.5 Hazardous area wiring
Information provided about I.S. barriers is intended as an overview. Application-specific or
product-specific questions should be addressed to the barrier manufacturer or
Micro Motion.
WARNING
• Hazardous voltage can cause severe injury or death. Shut off the power before wiring
transmitter outputs.
• Improper wiring in a hazardous environment can cause an explosion. Install the
transmitter only in an area that complies with the hazardous classification tag on the
transmitter.

The transmitter’s safety parameters require the selected barrier’s opencircuit voltage to be limited to less than 30 VDC (V
= 30 VDC). This
max
voltage is the combination of the maximum safety barrier voltage
(typically 28 VDC) plus an additional 2 VDC for HART communications
when communicating in the hazardous area.
The transmitter’s safety parameters require the selected barrier’s shortcircuit currents to sum to less than 300 mA (I
milliamp outputs and 100 mA (I
= 100 mA) for the frequency/discrete
max
= 300 mA) for the
max
output.
The capacitance (Ci) of the transmitter is 0.0005 μF. This value added to
the wire capacitance (C
) must be lower than the maximum allowable
cable
capacitance (Co) specified by the I.S. barrier. Use the following equation to
calculate the maximum length of the cable between the transmitter and
the barrier: C
+ C

The inductance (Li) of the transmitter is 0.0 mH. This value plus the field
wiring inductance (L
), must be lower than the maximum allowable
cable
inductance (Lo) specified by the I.S. barrier. The following equation can
then be used to calculate the maximum cable length between the
transmitter and the barrier: L

10 I/O wiring for 2700 with configurable
input/outputs
10.1 Channel configuration
The six wiring terminals are divided into three pairs, and called Channels A, B, and C.
• Channel A = terminals 1 and 2
• Channel B = terminals 3 and 4
• Channel C = terminals 5 and 6
Variable assignments are governed by channel configuration.
Table 10-1: Channel configuration
Channel Terminals Configuration options Power
A 1, 2 mA Output with HART/Bell202 Internal
B 3, 4 mA Output (default) Internal
Frequency Output Internal or external
Discrete Output Internal or external
C 5, 6 Frequency Output (default) Internal or external
Discrete Output Internal or external
Discrete Input Internal or external
Notes
• For Channel A, the Bell 202 signal is superimposed on the mA Output.
• You must provide power to the outputs when a channel is set to external power.
• When both Channel B and Channel C are configured for Frequency Output (dual pulse),
Frequency Output 2 is generated from the same signal that is sent to the first
Frequency Output. Frequency Output 2 is electrically isolated but not independent.
• You cannot configure the combination of Channel B as Discrete Output and Channel C
as Frequency Output.
