Sensor Wiring
The sensor cable can be quickly connected to the Q46 terminal strip by matching
the wire colors on the cable to the color designations on the label in the monitor.
A junction box is also available to provide a break point for long sensor cable
runs. Route signal cable away from AC power lines, adjustable frequency drives,
motors, or other noisy electrical signal lines. Do not run sensor or signal cables
in conduit that contains AC power lines or motor leads.
WIRING NOTE
:
The cable for the optical D.O. sensor contains a “black” wire that is
actually a black shrink tube covering both a blue and a pink wire.
These two wires connect to the same point designated by black in
Figure 14. If the cable is cut to a shorter length, be sure that both
wires are connected to the terminal marked black.
A yellow and a gray wire are contained in the cable and are
covered to avoid shorting. If the cable length is changed, do
not strip these two wires. If possible, leave sensor cable uncut
to avoid problems.
Note: If sensor is experiencing Low-Slope or Low-Output conditions, due
To poor Earth Ground Connections, move the Shield connection
from P/S board to alternate location on lid, where indicated with an
“S”.
