At the start of dosing, weight is cleared, close the exits n ° 1 (component 1) and 4 (active
dose); the display shows a "d" to indicate the status of dosage. When the NET WEIGHT
reaches the threshold value of the output component No. 1 No. 1 opens, if the threshold value
of the component No. 2 is greater than zero the display for a few seconds the message COMP-
2 and closes the exit n ° 2 and then deactivated to the achievement of the threshold value of
the second component.
Subsequently, if the dosing phase took place in the latter discharge is terminated and the 4th
exit opens; otherwise it starts the unloading phase: closes the exit n ° 3 and the display shows
a "U".
At any moment, the dosage can be paused by pressing the ESC key, closing the input 2 or
through a special serial command.
During this state the display will show "PAUSE"; pressing
or
is definitely possible to
continue or terminate the batch.
Throughout the dosing phase (LOAD and UNLOAD) output No. 4 remains active.
3.10 - Simple Dosage
This operating mode can be useful for filling containers, using only one type of product,
automatically if combined with the optional board I / O.
The dosage can be performed either in LOAD or in DISCHARGE.
The start of the dosage can be activated:
By KEYBOARD by setting a weight value confirming with the key
;
from EXTERNAL KEY (input 1 I / O card) if you have already made a dosage keyboard;
By SERIAL PORT by using the appropriate command.
The weight value of the dosage should not exceed the value or the value of the GROSS
WEIGHT CAPACITY - GROSS WEIGHT.
3.10.1 Load dosage
At the Start of dosage, any weight on the scale is automatically put into tare, the display
shows "d 0.0" to indicate the status of ongoing dosing and close the exits n ° 1, 2 and 4 (card
optional I / O).
When the net weight reaches the set threshold value, the display shows "u xx.x" indicating the
end of the assay with the amount of product present in the scale, the meter will remain in this
position until the balance will not be reduced to zero;
At this point the message "end" and can begin a new cycle of filling.
During the dosing step to load the logic outputs 1 and 2 change state to the achievement of
predefined values based on the measurement characteristics of the scale in use and the set
value for the assay;
Output 4 remains active for the duration of the dosage, and when the net weight reaches a
value measured at -20 divisions compared to the set value the status of outputs 1 and 2 will
change from "11" (closed / closed) "10" (closed / open); when the net weight reaches instead
a value measured at -10 divisions compared to the set value will switch to "01" (open /
closed), until it assumed the status of "00" (open / open) when they reach the 100% of the
threshold value.
At this point begins the unloading phase: closes the exit n ° 3 and the display shows a "U".
When the weight back to zero output 4 opens.
3.10.2 Unload dosage
At the Start of dosage, any weight on the scale is automatically put into tare, the display
shows "d 0.0" to indicate the status of ongoing dosing and close the exits n ° 1, 2 and 4 (card
optional I / O).
In this type of dosage the net weight dosed is subtracted from the scale for which there will be
a display of the quantity of dosed product in negative.
When the net weight reaches the set threshold value, the display shows the message "end"
and can begin a new cycle of filling.
During the dosing step to the discharge logic outputs 1, 2 and 4 change state to the
achievement of predefined values based on the measurement characteristics of the scale in
use and the set value for the assay;
