The load cell colour code in the above tabel is that used on
standard ADOS cells. Check carefully that the conductors function
correctly in the case where special ADOS cells or other brands of
cells are used. ATTENTION
-the incorrect connection of the wires or the inversion of poles
on the power supply may damage the apparatus
-the connection wires must not be connected to dangerous
power supplies
3.SETTING OF WEIGHING SCALE
The numeric value of the weight on the display consists of the
multiplication of two parameters: DIVIS AND SENSI, with the
possibility to set the number of DECIMALS required.
The number of divisions represents the number of steps that the
weighing rate is divided into; the more divisions set the easier it will
be possible to recognise small variations in weight.
The accuracy value represents the value associated with each
step of the weighing rate, and it should be chosen in order to reach
the required weighing rate.
The decimal values are needed to set the position of the point on
the weight display, in order to read the weight value in the correct
measure unit.
EXAMPLE: in order to obtain a weigh rate from 0 to 20000 units, it
is necessary to set a value of 10000 divisions with an accuracy of
2 units per division (10000 x 2 = 20000). In this way the weight will
be visualised in increments of 2. Another solution, though less
efficient, is that of setting a value of 2000 divisions with an
accuracy of 10 units per division: this however means that the
recognisable minimal variation in weight would be inferior.
In the case where the full scale weight is 20000 kg, if the decimals
are set at 0.0, the value displayed would go from 0.0 to 2000.0 with
increments of 0.2 kg.
DIVISIS SENSI’ DECIM
1000 1 0
2000 2 0.0
3000 5 0.00
4000 10 0.000
5000 20 0.0000
10000 50
The values available are:
N.B.: if it is not possible to obtain the desired weighing rate with the
combination of values available relating to divisions and accuracy,
the value should be rounded up: for example, in the case of a
weighing rate from 0 to 7000 the nearest obtainable would be 8000
4. CONFIGURATION OF PARAMETERS
to access configuration press ENT
press ENT again to access the configuration parameters
or press ESC to cancel
the name of the first parameter available will appear on
the display (for example the number of divisions)
use the INC and DEC keys to proceed to the next or
previous parameter
once the required parameter has been identified,
modifications can be made by pressing ENT
the parameter value will appear on the display and the
name of the parameter will flash intermittently.
use the INC and DEC keys to change the parameter
values (press the key for more than 3 seconds to
activate the automatic repetition option)
press ENT to confirm the set value or press ESC to
cancel
The configuration parameters available are as follows::
DIVIS number of divisions
(1000 - 2000 - 3000 – 4000 – 5000 - 10000)
SENSI accuracy values
(1 - 2 - 5 - 10 - 20 - 50)
DECIM number of decimals on the display
(0 - 0.0 - 0.00 - 0.000 - 0.0000)
MEDIE Number of data used for the dynamic average
(OFF - 2 - 4 - 8 - 16 – 32 - 64)
FUNR1 Relay number 1 functions
(ON - FAIL – POS G – NEG G – POS N – NEG N )
SETR1 Setpoint value of relay number 1
(from 0 to the full scale value)
FUNR2 Relay number 2 functions
(ON - FAIL – POS G – NEG G – POS N – NEG N )
SETR2 Setpoint value of relay number 2
(from 0 to the full scale value)
SERIA Setting of the serial port
(OFF - CONT - BIDIR)
LINE Selection of serial line type
(RS232 – RS485)
BAUD baudrate of the serial port
(1200 - 2400 - 4800 - 9600 - 19200)
ID485 Address for RS-485
(da 0 a 32)
The meaning of the DIVIS, SENSI, and DECIM
parameters is explained in paragraph 3.
MEDIE
This parameter is used for the digital filtering of the weight signal,
in order to reduce to a minimum the undesired effects due to for
example mechanical vibrations which affect the weighing system.
The higher the parameter value, the higher the capacity to filter the
undesired fluctuation, even if this causes an increase in the delay
of visualising the variations in the weight signal.
Pressing the OFF key excludes the filter option.
FUNR1 – FUNR2
ON: the relay is continuously excited; this option may be used to
check that the instrument is being powered
(excitation of the relay only stops due to the lack of power)
FAIL: excitation of the relay is interrupted when there is an
electrical fault in the +/- signal wires of the load cells.
NEG G: the relay is deenergized only if the weight value is lower or
equal to the preset value (see SETR1 and SETR2 parameters)
The set reacts independently from the zeroed value (by tare input).
POS G: the relay is deenergized only if the weight value is higher
or equal to the preset value (see SETR1 and SETR2 parameters).
The set reacts independently from the zeroed value (by tare input).
NEG N: the relay is deenergized only if the weight value is lower
or equal to the preset value (see SETR1 and SETR2 parameters)
POS N: the relay is deenergized only if the weight value is higher
or equal to the preset value (see SETR1 and SETR2 parameters).
SETR1– SETR2
This value represents the threshold used for the POS and NEG
options of the relay. The preset value ranges from zero to the full
scale.
