6.5.1 Signal "Enable"
The signal "ENABLE" corresponds with the two process channel signals BOUT "Ready" and BOUT
"Function fault" according to the following Boolean logic.
ENABLE = BOUT Ready

Function fault
Fig. 40: Boolean function "ENABLE"
If the signal BOUT "Ready" is reset, then a fault has occurred, which requires a user intervention at
the control unit. Possible causes: memory faults, missing or too low voltages.
6.5.2 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 signal is activated though a sheet is between the sensors, measuring

• Sheet too close to the transmitter / receiver
• Wrong type of sheet
• Sensor coverage not sufficient (3 × sensor diameter)
