Cause
Supply voltage is not correct.
• The sensor is disturbed by the
movement of the door.
• The door panels are detected by
the sensor.
• The door movement causes vi-
brations.
• There are objects in the detection
field which move in the wind.
• The sensing range is incorrectly
set.
• The detection angle is incorrectly
set.

Remedy
Check the voltage supply.
• Change the sensor's detection
angle.
• Check the sensor's mounting.
• Remove the objects (flags, plants,
etc.)
• Check the sensing range with the
test card.
• Readjust the detection angle (see
Chapter 3.3).
