Dynasonics MFX Series Insertion MagProbe Flow Meter - Manual (Page 14)

Rev. 01/11 -1.12- MFX
To access terminal strips for electronic connectors, loosen the two
screws in the enclosure door and open the door.
1. Guide the MagProbe terminations through the transmitter
conduit hole located in the bottom-center of the enclosure.
Secure the MagProbe conduit with the supplied conduit nut if
flexible conduit was ordered with the transducer. If conduit was
not purchased with the MagProbe sensor, an appropriate sealed
strain relief bulkhead fitting should be utilized.
2. The terminals within MFX are a pluggable type—they can be
removed wired and then plugged back in. Connect the
appropriate MagProbe wires to P1 (Sensor) at the corresponding
screw terminals on the
MagProbe module. Observe
proper wire colors and
shield connections. See
Figure 1.6 or the Wiring
Diagram located on the
inner door of the transmitter.
NOTE: The MagProbe cable
carries low level signals. Locate
the transmitter within the length
of MagProbe cable that was
supplied with the MFX system.
If this is not possible, replace
the entire length of interconnect
cable with Belden

performance can result.
Connect line power to the screw terminals marked L1, L2 and Earth
in the transmitter. See Figure 1.7 and Figure 1.8. Utilize the
conduit hole on the left side of the enclosure for this purpose. Use
wiring practices that conform to local codes (National Electrical
Code
®
Handbook in the USA). The earth ground terminal grounds
the instrument, which is mandatory for safe operation and optimum
flow meter performance.
