10.3.16
Zero offset adjustment
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 acquisition
When receiving a
dynamic zero acquisition
command
eNod4
calculates the average of successive weight measures
during the time specified in
dynamic zero acquisition time
parameter. A new zero is then used if the averaged value is
within a ±10% (±2% if the legal for trade option is enabled) range of the
maximum capacity
.
There is no stability criteria required. Dynamic zero acquisition can also be launch by an input assigned to this
function.
Dynamic zero acquisition
can be interrupted 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
parameter value must be stored before sending 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
Clear totalization & errors counter
This command triggers the main totalizer reset. The two parts of the totalizer, the main in
weight unit
x 1000, and the
complementary part in
weight unit
are then reset.
The variables
dosing errors report
,
dosing errors counter
and
last dosing error
are also reset.
10.3.22
Dosing / batch start / resume
In
batch mode
this command launches or resumes a cycle. A cycle can also be launched by an input assigned to this
function. When the command is sent through the
command register
,
eNod4
answers back the control state value
through the
response register
.
This command will not issue if a flow rate calibration has not been previously performed.
When a cycle starts and depending on parameters setting of eNod4, there will be firstly a refilling. Totalizer may be
cleared and a learning cycle initiated.
If a batch has been previously suspended, this command allows resuming the cycle and the totalization. The
dosing
status
variable allows monitoring enod4 state during the dosing cycle.
Attention: an input can only be assigned to
start/stop dosing
or
suspend/resume batch
, with a functioning in a
bistable mode and on rising or falling front depending on the selected logic.
10.3.23
Dosing stop / batch cancel
In loss in weight feeder mode, this command allows stopping the running dosing cycle. If a batch is pending, it will be
stopped with any possible resumption.
Attention: an input can only be assigned to
start/stop dosing
or
suspend/resume batch
, with a functioning in a
bistable mode and on rising or falling front depending on the selected logic.
10.3.24
Suspend batch
In
batch mode
this command suspends dosing. It allows any cleaning operation without clearing a batch. Launching a
Dosing / batch start/
resume command will resume the dosing cycle.
