3.4 Operating and display elements
3.4.1 Sensor LEDs
Des. Illuminated Blinking
POWER Green Sensor ready for operation -
OUTPUT Yellow No valid signal within the measurement
range
Critical signal quality
In the factory settings, the yellow LED follows the function of the alarm output. Alternatively, you
can select the function of the switching output for the yellow LED via Modbus RTU.
3.4.2 Teach button
Instead of parameterizing the sensor via the Modbus RTU protocol, you can configure the sen-
sor via the Teach button. Adjustable parameters:
n
Zero position (ZP)
n
Reset the sensor to the factory settings
INFO
You have the additional option of adjusting the mode of the Teach button via Modbus RTU. You
have a choice between Xpert (factory setting) and Xpress mode.
The teach button is automatically deactivated after 5 min (timeout can be parameterized via
Modbus RTU). When the teach button is pressed for longer than 12 seconds, the sensor returns
to operating mode without performing a parameterization.
Teaching the zero position
Instruction:
a) Press the teach button briefly.
ü Green and yellow LEDs light up (teach button is active). If the LEDs do not light up, the
teach button is deactivated by the timeout. Restart the sensor.
b) Keep the Teach button pressed for 2 seconds.
ü Green LED blinks with 2 Hz.
c) Place the object to be measured on the desired position for the zero point and briefly press
the teach button within 60 seconds.
Result:
ü Teach-in OK: Green and yellow LEDs light up briefly. Afterwards, the sensor returns to oper-
ating mode.
ü Teach-in not OK: Green and yellow LEDs blink simultaneously with 8 Hz.
After shifting the zero point, the digital values before the zero point (closer to the sensor) are
output with a negative sign. Distance values behind the zero point (furthermore the sensor) are
output with a positive sign.
