6.5.3 Signal "Warning"
The "Warning" signal is an additional output signal with fixed evaluation thresholds.
The signal becomes activated if the measurement result is below 80% or above 120% of the preset
nominal value.
Application:
If the "Warning" is active in the measurement, though only one sheet in front of the sensor,
measurement problems may have occurred:
• Air gap between sensor and sheet
• Wrong type of sheet
• Sensor coverage not sufficient

Note If these requirements are met, but a warning signal is issued, then the
Teach-In must be repeated. The requirements from section "4.3 Sensor
mounting" should be observed.
Note The signal will also be activated if measurements without a sheet
(measurement value <80%) and measurements with double sheet / two
sheets (measurement value >120%).
