• total belt length
• number of revolutions
10.3.22 End speed sensor calibration
When the configured number of revolution is realized, this command will cause eNod4 to achieve and to exit speed
calibration sequence. The new “Pulses factor for speed” is calculated and the speed given by eNod4 will match the
real belt speed. Also, eNod4 will know how long for the belt revolution.
10.3.23 Init belt length calibration
When the system is running empty, this command will cause eNod4 to initiate belt length calibration sequence.
An internal timer is restarting and the calibration procedure duration will depend of the current belt speed, the belt
length and the number of revolutions to handle.
Important: Before initiated belt length calibration procedure, user has to configure the following parameters:
• Pulses factor for speed(could be found in speed sensor user manual or determinate by eNod4)
• number of revolutions
10.3.24 End belt length calibration
When the configured number of revolution is realized, this command will cause eNod4 to achieve and to exit belt
length calibration sequence. The new “total belt length” is calculated and eNod4 will know how long for the belt
revolution.
10.3.25 Flow rate correction
Correction factor can be used to correct deviations in the total dosed amount by compensating for mechanical
variations. At receiving a “flow rate correction” command eNod4 recalculate a correction factor by calculating:
New Correction = Checked Batch Total * Correction / Last batch total.
The next batch the Batch Total and Checked Batch Total should be closer together.
Important: Before initiated this command, user has to configure the “Checked Batch” parameter.
10.3.26 Start (batch/system)
In batch mode this command launches or resumes a cycle. A cycle can also be launch by an input assigned to this
function. If the start is given by the command register, eNod4 responds through the response register, the state of the
control cycle start. If the cycle has been started, then the bits of “belt status word” will be positioned (see § belt status
word).
In weigh feeder mode and if eNod4 analog output is assigned to “flow rate control output” and drives the “conveyor
speed”, this command will start the belt system at “nominal speed” configured. In that case, for security reason a
logical output can be assigned to “buzzer” function and the duration is configured through “conveyor starting alarm
duration” parameter.
10.3.27 Stop (batch/system)
In batch mode this command allows stopping the batch cycle. It is also possible to order a ‘stopping of cycle’ with an
input set to this function. At receiving of this command, the scale material flow stops automatically.
In weigh feeder mode and if eNod4 analog output is assigned to “flow rate control output” and drives the “conveyor
speed”, this command will also stop the belt system.
10.3.28 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 variable errors counter is also reset.
