Transducer Cable Connection at the Transmitter
(no IS Barriers)
The transducer cable should enter the transmitter enclosure through
gland E on the bottom of the transmitter enclosure (See Figure 3.15.) If
the transmitter is
not
equipped with IS Barriers (refer to Section 2.4),
the sensor cable is wired directly to the transmitter motherboard
terminal blocks
J10
(transducer drive and response signals) and
J11
(transducer RTDs (temperature sensors.) The individual transducer
cable wires are color-coded and labeled with numbers.
Transducer cable to transmitter connections are shown in Table 3.1.

3.7.2.1 Connecting the Transducer Cable at the
Transmitter (No IS Barriers)
Connect the individual color-coded wires of the transducer
cable to the numbered terminal positions on the terminal
blocks as shown in Table 3.1.
**
The shield / drain wires of the transducer cable twisted
pairs are internally coupled to each other and to the
orange
wire. The
orange
wire is connected to earth ground via the
chassis ground of the transmitter.
Do NOT attach the
orange wire at the transducer end of the cable.
To Connect the Transducer Cable Orange Wire to Earth
Ground via the Transmitter Chassis:
•
Remove the
orange
topped screw on the chassis.
•
Center the ring terminal of the orange wire over the
screw hole.
•
Reinsert and firmly tighten the
orange
topped screw.
