6.3 Adjustments
L/D Switching
The sensor may be specified with a Light Switching or Dark Switching
(L/D) selection potentiometer.
Light Switching is selected for the Q1 output by rotating the poten‐
tiometer counterclockwise to the stop position. The potentiometer tab
will point toward the “L” printed on the sensor housing.
Dark Switching is selected for the Q1 output by rotating the poten‐
tiometer clockwise to the stop position. The potentiometer tab will
point toward the “D” printed on the sensor housing.
CAUTION
Over rotation of the potentiometer past the stop positions will cause permanent dam‐
age to the sensor.
If complimentary outputs are specified (Hx18-Pxxxxx, Hx18-Nxxxxx, Hx18-Fxxxxx), the
Q2 output will always be opposite switching state of the Q1 output. Therefore, the Q2
output will be Dark Switching when the potentiometer is in the “L” position and Light
Switching in the potentiometer is in the “D” position. If bipolar outputs are specified
(Hx18-Axxxxx, Hx18-Bxxxxx), the Q2 output will always have the same switching state
as the Q1 output. The L/D selection potentiometer does not impact a Health or Alarm
output (if specified).
