Sensi vity
Controls the level of amplifi ca on applied to the target signal. The sensi vity
se ng is expressed as a percentage; 0 to 100%. When opera ng in Autosense
mode, the Sensi vity se ng acts as an upper limit constraint (see Gain Control
for details).
Blanking
Sets the distance, beginning at the sensor face, to the point where the sensor
will begin looking for target signals. All targets closer than the blanking distance
will be ignored. The blanking should never be set to less than the minimum
range specifi ca on of the sensor. If the target enters the blanking area, errant
readings will occur.
NOTE: the LOE-6126 has the ability to track a target to as close as 1” from
the sensor face. This feature is limited to targets that will remain perfectly
perpendicular to the sensor face.
This feature is enabled by se ng the Gain
Control to 1 (Autosense) and then se ng the Blanking to 0.
Pulses
Controls the number of sound wave pulses being sent in each ultrasonic
burst. The greater the number of pulses, the stronger the transmi ed signal.
When opera ng in Autosense mode, the Pulses se ng acts as an upper limit
constraint (see Gain Control for details).
Gain Control (0, 1, 2, 3)
Determines the method in which gain is applied to returning target signals. In
Manual mode, the Sensi vity and Pules se ngs are applied as a sta c values.
In Autosense Mode, the sensor self-adjusts the Pulses and Sensi vity levels
(within the bounds of their respec ve se ngs) in order to op mize the signal
strength.
0 = Manual Mode (sta c Sensi vity & Pulses values)
1 = Autosense (auto-adjus ng Sensi vity & Pulses values)
2 = Hard-Target (increases gain slowly as distance increases)
3 = So -Target (increases gain quickly as distance increase)
