Direct Sensor Wiring
Sensor connections are made to a terminal block mounted on the front section of the monitor.
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. 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 wiring.
Note
: There are 3 additional wires in the sensor cable that should not be connected. These wires
allow sensor firmware to be upgraded should that be needed in the future.
