Programmable Parameters
All adjustments made to these parameters are stored in memory and are retained when power is
removed. To enter programming mode press and hold the
P/-
key for several seconds, the current
threshold setting will be displayed. Press and release the
P/-
key to scroll through the various settings.
Press and release the
T/+
key to change a particular setting. Press and hold the
P/-
for several seconds
to return to the normal intensity display mode. The user programmable items are described below.
Threshold
When the relative intensity level exceeds the threshold setting the red status LED will turn on and
the discrete output will activate, indicating detection of the target. When the relative intensity
level drops below the threshold (as determined by the hysteresis setting), the red LED will
extinguish, and the discrete output will de-activate. The threshold setting allows the user to
select the detection level. The default setting is 15.
To adjust the threshold, enter programming mode, press and hold the
P/-
key for several
seconds, the current threshold setting will be displayed. Press and release the
T/+
key to
increase
the threshold level, to decrease the threshold level, continue to hold the
T/+
key until the value
approaches 99 then wraps around to 00.
LED Intensity Level (U)
The LED intensity is indicated on the display as U1, U2 and U3 for low, medium and high intensity.
Press and release the
T/+
key to toggle through the 3 intensity levels.
The default setting is U2,
medium intensity.
Hysteresis Level (H)
The hysteresis setting is indicated by H0 through H9. The hysteresis level is how far below the
threshold the signal must fall to de-activate or un-detect. The hysteresis can be set from 0 to 9.
For example, if the threshold is set at 25 and the intensity exceeds 25, the sensor will detect and
activate its output. With the hysteresis set to 5, the signal must drop to 20 to un-detect. This
feature is useful in cases where there may be variation within a target that might cause the
intensity to drop below the threshold slightly; the hysteresis allows the output to remain
activated until the level drops significantly. Press and release the
T/+
key to change the hysteresis
setting. The default setting is 2.
Discrete Output Configuration
This setting allows the user to select either normal open (no) or normally closed (nc)
configuration. The normally open configuration de-activates the output during normal un-detect
operation, and activates the output upon detect. The normally closed configuration activates the
output during normal un-detect operation, and de-activates the output upon detect. Press and
release the
T/+
key to toggle through the selections. Default is normally open
