Conductivity Sensor

Depending on how transmitter is mounted, route the sensor
(or interconnect) cable into the transmitter as follows:
•
Wall/Pipe-mounted Transmitter:
Route cable through
left side cable entry knockout hole in the back cover.
•
Panel-mounted Transmitter:
Route cable behind panel
to the exposed TB2 terminal strip.
•
Integral Sensor-mounted Transmitter:
Route cable
through swivel ball knockout hole and center hole in
back cover. (Do not open left side cable entry knockout
hole in back cover.)
Wiring Tip!
Route the sensor cable in 1/2-inch,
grounded metal conduit to protect it from moisture,
electrical noise, and mechanical damage.
For installations where the distance between sensor and
transmitter exceeds the sensor cable length, indirectly
connect the sensor to the transmitter using a junction box
and interconnect cable.
NOTE:
Do not route the sensor cable in any conduit con-
taining AC or DC power wiring (“electrical noise”
may interfere with the sensor signal). Also, always
re-calibrate the system when the cable length be-
tween sensor and transmitter changes.
Refer to Figure
S

AND!
and connect the sensor
(or interconnect) cable wires as shown, matching colors
as indicated.
(Terminal 6 is unused.)
NOTE:
For systems not requiring CE compliance and
lacking an earth ground, connect the outer shield to
Terminal 3 on TB2.
