Wire the sensor to the remote core processor
1. Refer to Micro Motion’s
9-Wire Flowmeter Cable Preparation and Installation Guide
and
follow the instructions on cable shielding and preparation.
•
At the sensor end, follow the instructions for your cable type.
•
At the core processor end, follow the instructions for your cable type with an MVD
transmitter.
2. To connect the wires, refer to Micro Motion’s
9-Wire Flowmeter Cable Preparation and
Installation Guide
and follow the instructions for your sensor with an MVD transmitter.
Additional information for connecting the wires at the core processor is provided
below:
a. Identify the components shown in
Figure 2-1
.
b. Remove the core processor’s end-cap.
c. Insert the 9-wire cable through the conduit opening.
d. Connect the wires to the plugs supplied with the core processor.
e. Insert the plugs into the sockets inside the lower conduit ring. See
Figure 3-17
.
Connection type
Procedure
Screw-type connectors
Connect the four wires from the core processor to the appropriate
terminals on the transmitter. See
Table 3-3
and
Figure 3-6
.
•
Do not expose bare wires.
•
Do not ground the shield, braid, or drain wires at the transmitter.
I/O cables
1. Attach the supplied terminal block to a DIN rail. The terminal
block accommodates various rail types. See
Figure 3-8
.
2. Plug the I/O cable connector onto the terminal block. Tighten
the captive screws to secure the connector to the terminal
block.
3. Connect the four wires from the core processor to the
appropriate terminals on the terminal block. See
Table 3-3
and
Figure 3-9
. No bare wires should remain exposed. Do not ground
the shield, braid, or drain wire(s) at the transmitter.
CAUTION!
Do not allow the shield drain wires to contact the sensor junction box, as this can cause meter
errors.
