Possible cause
No voltage supply
• Undervoltage
• Overvoltage
Sensor was brought into the
safe state (logic "0")� Cause:
• cross fault between both
outputs A1 and A2
• cross fault between output
A2 and the supply voltage
• error in the sensor detected
Due to its characteristics
(material, form, size), the
damping element displaces
the enable zone until directly
in front of the sensing face
