ADC+OVER or ADC-OVER
The above shows the condition in which the input electrical signal cannot be converted
into a correct digital value because the input electrical signal exceeds the input voltage
range of the component (ADC) that converts input electrical signals to digital values.
ADC+OVER shows that the input electrical signal exceeds the input range in the
positive direction, and ADC-OVER shows that the signal exceeds the range in the
negative direction.
This is also caused when an excessive load is given to the sensor, or when the input
terminal is opened by a break in cabling.
+OVER or -OVER
The above shows that the displayed value exceeds the normal display range.
The normal display ranges are -9999 =< Y-axis =< 9999, and -9999 =< X-axis =< 9999.
+OVER shows that display of a value out of the range in the positive direction has been
attempted, and -OVER shows that display of a value out of the range in the negative
direction has been attempted.
This is caused when a load larger than expected is given to the sensor, or when
calibration is performed below the measuring range. Check calibration, measuring
object, etc.
Calibration error
The above shows the condition in which calibration cannot be performed because the
input electrical signal exceeds the calibration range. Check the cables for breaks and
miswiring.
Even if any of the above errors is displayed, the F395 will not be damaged immediately.
However, in the ADC+OVER or ADC-OVER condition, it is considered that excessive
voltage may be given to the input circuit of the F395, therefore remove the causes
immediately.
(The input circuit is provided with a protective circuit, but it may be damaged if the input
is excessive over a long period of time or even if it is instantaneous.)
