How can the mode CC be used, if the SONO
probe cannot detect the „moisture threshold“ by
itself, e.g. if there is constantly material above the probe over a longer time: In this case, a short
interrupt of the probe´s power supply, e.g for about 0.5 seconds with the help of a relay contact of the
PLC, can restart the SONO probe at the beginning of the material transport. After this short interrupt
the SONO probe starts immediately with the summarizing and averaging.
Please note: It should be noted that no material sticks on the probes surface. Otherwise the moisture
zero point of the probe will be shifted up and the probe would not be detect a moisture low value
below the “Moisture-Threshold”.
Following possible parameter settings in mode CC inside the SONO probe can be set:
Parameter in mode CC Function
Moisture Threshold
(in %-moisture)
Standard Setting: 1
Setting Range: 1….20
The accumulation of moisture values starts above the
„Moisture Threshold“ and the analogue signal is
output. The accumulation pauses if the moisture level
is below the threshold value.
No-Material-Delay
(in seconds)
Standard Setting: 5
Setting Range: 1….20
The accumulation stopps if the moisture value is below
the moisture threshold. The SONO probes starts
again in a new batch with a new accumulation after the
time span of
the “No-Material-Delay” is exceeded.
