Note 1
: Functioning and calibration parameters are stored in EEPROM. After every reset the entireness of parameters
stored in EEPROM is checked. If a defect appears, measurements are set to 0xFFFF and defect is pointed out in
measurement status. Causes a logical output assigned to the ‘defective measurement’ function to be set active.
Causes the analog output assigned to a weight or flow rate image to be set in error mode.

Weighing diagnosis
9.2.1
Global weighing diagnosis
An internal alarm flag reflects the integrity of the whole measurement chain. It’s used to set logical output active or
optional analog output in an error mode in order to warn about any defection on the measurement chain (defective
measurement).
This variable is set active when at least one of the followings conditions occurs:
-
all that set bit2 or bit3 of
Measurement status:
•
sensor input control result out of tolerances
•
sensor input control command in progress
•
sensor input control command failed (timeout)
•
sensor input reference command in progress
•
gross meas. < (- max capacity)
•
gross meas. > (max capacity)
•
analog signal out of the A/D converter input range
-
the one that set bit6 of
Measurement status:
EEPROM failure
This internal alarm flag is featured with adjustable specific de-bounced time and minimal activation time:
9.2.1.1
Defective measurement debounced time
The internal alarm flag is set active only after error conditions have always been true during this de-
bounced time. It’s
expressed in ms.
9.2.1.2
Defective measurement alarm activation time
The internal alarm flag remains active for this minimal
“defective measurement alarm activation time”
when it come
to be active and whatever the error conditions are during activation. It is expressed in ms.
