Measuring Sensor Output
To measure the output of the LD3xi/LD3xiC, the sensor needs to
have an excitation voltage applied to it from a signal processor, a DC
voltage generator, or a KM test meter.
To use the excitation from the KM Test Meter, put the switch in
the simulate position and wire the positive to the red position
and the negative to the black position.
Turck Option
The excitation would be applied to the excitation wires or the quick
disconnect cable, brown (positive) and black (negative). The
millivolt signal would be measured with a multimeter on the output
wires, white (positive) and blue (negative).
Standard Fixed Cable
The excitation would be applied to the excitation wires of the
standard fixed cable, red (positive) and black (negative). The
millivolt signal can be measured on the output wires, white (positive)
and Yellow (negative).
