Sensi! vity (0 to 100%) (40408)

Controls the level of ampliﬁ ca" on applied the returning target echoes (signals).

The sensi" vity se# ng is expressed as a percentage; 0 to 100%. When operat-

ing in Autosense mode, the Sensi" vity se# ng acts as an upper limit constraint

(refer to Gain Control below for more informa" on on Autosense).

Pulses (0 to 20) (40409)

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 (refer to Gain Control below for more informa" on on Autosense).

Blanking (0 to 10364 mm) (40410)

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.

Gain Control (0 = Manual Mode; 1 = Autosense Mode) (40411)

Determines how the sensor applies gain (ampliﬁ ca" on) to returning target

echoes. 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 level.

Averaging (1 to 20) (40412)

Deﬁ nes the number of readings that will be averaged together to become

the Calculated Value. Each qualiﬁ ed reading (see Filter Window and Out of

Range Samples on next page) is placed into a ﬁ rst-in, ﬁ rst-out (FIFO) buﬀ er

and averaged with previous readings. A higher Averaging se# ng will result in

smoother readings, but will also slow the response to rapid target changes.
