10.3.14 Store calibration
Only if the ‘segment 1/2/3 acquisition’ is successful, next step consists in validating the new calibration by storing the
zero and the span that have been determined in EEPROM.
Note: This functional command has to be transmitted at the end of a physical calibration, after a ‘zero adjustment’, a
‘theoretical scaling’ or a ‘zero offset’.
10.3.15 Logical outputs 1-4 activation/deactivation
If the corresponding logical outputs are assigned to the ‘level on request’ function, they can be enabled/disabled by
transmitting one of these functional commands. Upon first reception, the corresponding output is enabled and on
next reception it will be disabled. If the requesting logical output is assigned to the wrong function, eNod4 reports an
error.
10.3.16 Zero offset
It is also possible to adjust the calibration zero value without acquiring a new one. By entering a positive or negative
value into the ‘delta zero’ register, the user can quantify the offset (in factory calibrated points) that has to be added
or subtracted from the actual calibration zero. This calibration zero modification must then be saved by sending to
eNod4 the ‘store calibration’ functional command.
10.3.17 Dynamic zero
In belt mode and when the system is running, after receiving a “dynamic zero” command eNod4 calculates the
average of integrated weight per length during the belt revolution time. A new zero is then used if it is within a
“dynamic zero band” parameter range. For more accurate result, dynamic zero can be done within several belt
revolutions specify by “number of revolutions” parameter.
• Note 1: Stability is not necessary
• Note 2: Dynamic zero acquisition can also be launch by an input assigned to this function.
• Note 3: Dynamic zero procedure can be interrupt by sending “cancel current command”.
10.3.18 Preset tare
With this command it is possible to retrieve a tare value defined previously.
Important: Preset tare value must be stored in corresponding parameter before to send this command.
10.3.19 Sensor input reference
Sensor input reference command will cause eNod4 to handle special sequence to acquire sensor input control
reference value of the load cell sensor input. This command must not be realized when any process cycle that use
weight is in progress (because weight variables do not reflect the real weight whilst command is in progress). This
command can fail (error in response register) in case of stability timeout on sensor input. The execution time of this
command depends on the weight filtering settings. For any further information about this functionality and result
variables see “Weighing diagnosis” § in the MEASUREMENT AND STATUS §.
10.3.20 Sensor input control
Sensor input control command will cause eNod4 to handle special test on sensor input and to deliver a test result. This
command must not be realized when any process cycle that use weight is in progress (because weight variables do not
reflect the real weight whilst command is in progress). This command can fail (error in response register) in case of
stability timeout on sensor input. The execution time of this command depends on the weight filtering settings. For
any further information about this functionality and result variables see “Weighing diagnosis” § in the MEASUREMENT
AND STATUS §.
10.3.21 Init speed sensor calibration
When the system is running empty, this command will cause eNod4 to initiate belt speed calibration sequence.
An internal speed sensor pulses counter is restarting and the calibration procedure duration will depend of the current
belt speed, the “total belt length” and the “number of revolutions” to handle.
Important: Before initiated speed calibration procedure, use has to configure the following parameters:
