- Totalisation of the dosed weight;
- Display of the accumulated totals;
- Manual dosage cycle end or automatic (by weight or by time);
- Printing of the dosage data, programmable;
- Transmission of the dosed weight through an output (impulse counter);
- Checking the minimum/maximum weight.
For the description of all these functions, refer to section DESCRIPTION OF THE COMMON FUNCTIONS
- Reading of the flow and the total weight dosed using the serial interface. Refer to the technical manual
(TECH.MAN.REF.)
for the functioning specifications.
NOTE:
By using the Sysway protocol, it’s possible to have the reading of the dosage data and the cancellation of the
general total. With the profibus and modbus protocols it is also possible to configure the dosage parameters of the
instrument.
- Analogue output proportional to the flow. For the description of this function, refer to section SPECIFIC FUNCTIONS OF
THE READER MODE.
12.2.2 "REGULATOR" MODE: FLOW REGULATOR
Premise:
this functioning mode requires the optional analogue board.
Besides the flow reader mode functions, the instrument allows to adjust the flow to a value entered through the keyboard or
set from external device externally (see section ANALOGUE OUTPUT (OPTIONAL)). The analogue output is used to pilot
the hourly flow monitoring device.
FUNCTIONS:
All the READER mode functions (but with a different management of the analogue output).
For the description of the common functions, refer to section DESCRIPTION OF THE COMMON FUNCTIONS
Specific functions of the regulator mode:
- Target flow entered from keyboard or set from external device (through optional analogue input)
- Control/Adjustment of the flow through the relay/analogue output (OPTIONAL)
- Dosage start optimization
- Correction of weight error of dosed material
For the description of all the function of the flow regulator mode, refer to section SPECIFIC FUNCTIONS OF THE
REGULATOR MODE
12.3 DESCRIPTION OF THE COMMON FUNCTIONS
12.3.1 DISPLAY OF THE HOURLY/WEIGHT FLOW
During the weighing cycle, the instrument shows the hourly flow of the system on the display; by pressing the
2ndF
+
F8
key, one switches the display of the weight on the weighing system. The flow’s unit of measure depends on the value set in
the FLOW RATE UNIT OF MEASURE step (
<<F.R.U.M>> kg/h
to default ).
12.3.2 TOTALISATION OF THE DOSED WEIGHT
The instrument is fitted with three different total levels (Partial total, General total, Article total), each of which is increased
during the weighing cycle according to the detected flow rate. The unit of measure of these totals depends on the scale’s
unit of measure:
Scale unit of measure
Total unit of measure
g

kg
kg
The totalisation begins from the start of the dosage and ends when the dosage cycle is stopped, as soon as the instrument
reaches the set weight target or once the set dosage time has passed, depending on the dosage cycle end mode.
It is anyway possible to manually pause or end the dosage under way; if the instrument is in the pause status, by reenabling
the dosage, the increase of the partial total will take place starting from the value accumulated until the pause status,
