Failure to connect the
orange
wire as described above may
lead to increased susceptibility to external interference,
unstable operation, and / or inaccurate measurements.
Galvanic Applied Sciences assumes no risk nor liability for
any outcome associated with the failure to make the
above described ground wiring connection.
Transducer Cable Connection at the Transmitter
(with IS Barriers)
If the system
is
equipped with IS Barriers (refer to Section 2.4), the
individual wire connections between the motherboard terminal blocks
J10
and
J11
and the
(transmitter)
non-intrinsically safe side
of the IS
barriers have been made at the factory. Connection of the transducer
cable to the intrinsically safe side of the IS barriers must be performed
at the time of installation, after the transducer cable has been fed
through the conduit.
3.7.3.1 Connecting the Transducer Cable at the
Transmitter (IS Barriers: Intrinsically Safe
Side)
•
Connect the
transducer cable
to the
intrinsically safe
side
of the IS barriers according to Figure 3.10 (
General
Application / Standard IS Barrier Configuration
) or
Figure 3.11 (
High Temperature IS Barrier Configuration
)
as appropriate for your configuration. If the transducer
includes a transducer block RTD for transducer block
temperature measurement, use Figure 3.11. Otherwise,
use Figure 3.10.
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.
