Ultrasonic sensor
Programming procedure
The sensor features a single output with two programmable switch points. Programming the switch points and the operating mode can be done
in three different ways:
• via the sensor’s Programming Button
• by applying the supply voltage 0 V or +U
B
to the Program input (only for programming the switch points)
• via the serial interface, which requires an external interface adapter
Procedures for programming via the sensor's Programming Button and the Program input are described below. For programming using the serial
interface, please refer to the software manual. Switch points and operating modes can be programmed independently without influencing each
other
Note:
• Programming is enabled for 5 minutes after power-on. After 5 minutes without programming activity the programming feature will be locked.
• During any programming step it is possible to leave the programming routine without changing the sensor settings by pressing the
Programming Button for 10 s.
Programming the Switch Points
Note:
If the red LED flashes during the programming procedure, it indicates uncertain target detection. In this case, please correct the target alignment
until the yellow LED flashes. The new settings will only be stored in the sensor’s memory if the yellow LED flashes.
Programming Switch Points using the Internal Programming Button
Programming the Near Switch Point
1. Place the target at the desired near switch point position
2. Press the Programming Button for 2 s (yellow LED flashes)
3. Press the Programming Button briefly (green LED flashes three times for confirmation). The sensor returns to normal operation.
Programming of the Far Switch Point
1. Place the target at the desired far switch point position
2. Press the Programming Button for 2 s (yellow LED flashes)
3. Press the Programming Button for 2 s (green LED flashes three times for confirmation). The sensor returns to normal operation.
Programming Switch Points by using the Program input wire
Notes:
• Before entering program mode the program input wire must be open circuit for at least 2s.
• If potential (0V or +U
B
) is applied for >10 s the sensor resumes normal operation without changing settings. To ensure successful
programming, disconnect the Program input before this 10 s time period elapses.
• If the program input is not used, the wire should be connected to 0 V.
• If programming adapter UB-PROG2 is used for the programming procedure, button A1 is assigned to 0 V and button A2 is assigned to +U
B
.
Please make sure, that the cordset’s wire, which is connected to the Program input is not connected (open circuit).
Programming the Near Switch Point
1. Place the target at the desired near switch point position
2. Apply 0 V to the Program input for 2 s (yellow LED flashes, then green LED flashes three times for confirmation). Then sensor returns to normal
operation.
Programming the Far Switch Point
1. Place the target at the desired far switch point position
2. Apply +U
B
to the Program input for 2 s (yellow LED flashes, then green LED flashes three times for confirmation). Then sensor returns to
normal operation.
Programming Modes of Operation
The sensor provides a three step routine to program the modes of operation. In this routine you can program:
1. Output function
2. Output behavior
3. Beam width
Programming the modes is carried out sequentially. To toggle from one mode to the next, press the Programming Button for 2 s.
Press the Programming Button for 5 s to enter the operating modes programming routine.
Programming the output function
1. The green LED flashes. The number of flashes indicates the current output function:
single flash: Switch point output function
double flash: Window output function
triple flash: Hysteresis output function.
2. Press the Programming Button briefly to toggle sequentially through these output functions and select the desired mode.
3. Press the Programming Button for 2 s to save and enter the programming routine for output behavior
Programming the output behavior
1. The yellow LED flashes. The number of flashes indicates the current output behavior:
