Product Description
A family of diffuse ultrasonic
sensors in stainless steel
housing and with a sensing
range of 40-300 mm and
80-800 mm with a resolution
as low as 3.0 mm. The sensor
contains an analogue output
that is either 0-10 V or 4-20
mA.
This sensor is the ideal choice
for distance measurement,
level measurement, diameter
measurement or loop con-
trol. Due to the use of micro-
processor control the digital
filtering makes the sensor
immune to most electro-
magnetic interferences.

Programming set-up
Teach-in by wire adjustment options
In the following,
“Activate
Teach”
means:
Connect the white wire to GND (Blue wire)
Two Teach-in adjustment options are available:
1) Window Teach-in Option (adjustment of two points: P1 and P2)
Teach-in of set point P1:
• Place the target at the selected far distance P1 - the green Echo LED is ON
•
“Activate Teach”
shortly
• Setpoint P1 has been stored and the sensor is still in teach mode
• The orange LED will continue flashing rapidly with a frequency of 2 Hz until the setpoint P2 has been learned
Teach-in of set point P2:
• Place the target at the selected close distance P2 - the green Echo LED is still ON
•
“Activate Teach”
shortly
• The green LED switch OFF and the orange LED will flash 5 times with a frequency of 2,5 Hz
• Setpoint P2 has been stored.
• The sensor is in normal mode and the green and yellow LEDs are steady.
2) Target adjustment on P1 only (Minimum P2 distance)
Teach-in of set point P1:
• Place the target at the selected far distance P1 - the green Echo LED is ON
•
“Activate Teach”
shortly
• Setpoint P1 has been stored and the sensor is still in teach mode
• The orange LED will continue flashing rapidly with a frequency of 2 Hz until setpoint P2 has been learned
• Without moving the target
• “Activate Teach” shortly
• The green LED switches OFF and the orange LED will flash 5 times with a frequency of 2,5 Hz
• Setpoint P2 has been stored at the minimum distance
• The sensor is in normal mode and the green and yellow LEDs are steady

Configuration of the slope of the analogue output
The analogue version’s default setting is positive slope.
Change configuration from positive to negative slope:
•
“Activate Teach”
for more than 6 seconds until the orange LED flashes at a high rate/10 times per second.
•
Deactivate Teach:
The orange LED flashes 5 times, and the output stage is changed.

Installation Hints
To avoid interference from inductive voltage/
current peaks, separate the prox. switch
power cables from any other power cables,
e.g. motor, contactor or solenoid cables
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
Incorrect
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
