Distance measurement sensor with IO-Link interface VDM28-8-L1-IO/33/110/115b/122

Release date: 2017-10-16 12:24 Date of issue: 2017-10-16 297904_eng.xml
A empty -> zero start point
Reset to default settings:
Factory setting for switching output Q1:
• Switching output inactive
Factory setting for analog output Q2:
A = 200 mm
B = 5000 mm
• Set the rotary switch to the "RUN" position
• Press and hold the "SET" button until the yellow and green LEDs stop flashing in phase (approx. 10 s)
• When the green LED lights up continuously, the procedure is complete.
Error messages:
• Short circuit: In the event of a short circuit at the sensor output, the green LED flashes with a frequency of approx. 4 Hz.
• Teach error:In the event of a teach error, the yellow and green LEDs flash alternately with a frequency of approx. 8 Hz.
• The irradiation can lead to irritation especially in a dark environment. Do not point at people!
• Maintenance and repairs should only be carried out by authorized service personnel!
• Attach the device so that the warning is clearly visible and readable.
• Caution – Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation
exposure.
Value B cannot be deleted
The "zero start point" operating mode can be obtained by deleting value A
Note!
The difference in the taught-in distance measured values for switching thresholds A and B
must be greater than 20 mm.
If the difference in the taught-in measured values is the same as or smaller than the set
switching hysteresis, the sensor will visually signal an unsuccessful Teach-In. The last
distance measured value that was taught in will not be adopted by the sensor.
Select a new distance measured value for switching threshold A or B with a greater difference
between the switching thresholds.
Teach in this distance measured value on the sensor again.
Switching threshold A can be deleted or set to a value of zero.
(E.g., when setting the "zero start point" curve).
However, switching threshold B can neither be deleted nor set to a value of zero.
