personnel. To lock the sensor, press the P/- and T/+ buttons for 3 seconds until LL is displayed. To
un-lock the sensor, press the T/+ and P/- for 3 seconds until LL is not displayed. While the sensor is
locked, pressing either P/- or T/+ will result in LL (Local Lock) indication on the display.
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.
Extend Output Pulse (P)
This feature allows extending the minimum length of time that the discrete output remains active
following target detection. The sensor response can be in the 100uS (microsecond) range, i.e. a
target can move through the sensing range in 100uS and the discrete output would active for only
that duration. A slower acquisition system (PLC) may not sample its inputs at a fast enough rate to
capture the signal. The discrete output pulse can be extended from 0 to 90mS (milliseconds) in 10
mS increments as indicated by P0 though P9 on the display. Press and release the T/+ key to toggle
through the selections.
