CONNECTIONS OF THE LOAD CELL/S
The cell/s cable must not be channeled with other cables, but must
follow its own path.
The instrument can be connected up to a maximum of 8 load cells
of 350 ohm in parallel. The supply voltage of the cells is 5 Vdc and
is protected by temporary short circuit.
The measuring range of the instrument involves the use of load cells
with a sensitivity of up to 3.5 mV / V.
The cable of the load cells must be connected to terminals 19-24.
In the case of 4-wire load cell cable, jumper the terminals 19 to 22
and 20 to 21.
Connect the cell cable shield to the terminal 2.
In the case of the usage of two or more load cells, use special junction
boxes (CEM4/C or CSG4/C). Below please find their connection.
LOGIC INPUTS
The two logic inputs are opto-isolated.
The cable connecting the logic input should not be channeled with
the power cables.
The function of the two inputs is as follows:
INPUT1 Resetting the displayed value (gross, net or peak)
INPUT 2 PRINT
The activation of the two functions is accomplished by bringing the
external power supply 24 Vdc to the corresponding terminals as
shown in the figure.

LOGIC OUTPUTS
The two opto-isolated relay outputs are the normally open contact.
The capacity of each contact is 24 Vdc, 100 mA max.
The cable connecting the outputs should not be channeled with the
power cables. The connection should be as short as possible.
SERIAL COMMUNICATION
RS232:
The RS232 serial port is always present and handles various pro-
tocols.
To achieve the serial connection, use a shielded cable, making sure
to connect the shield to one of the two ends: to pin 8 if connected
on the side of the instrument, to the ground if it is connected on the
other side.
The cable must not be channeled with power cables; the maximum
length is 15 meters (EIA RS-232-C), beyond which you should take
the optional RS485 interface.
ANALOG OUTPUT (OPTIONAL)
The transmitter provides an analog output in current and voltage.
Analog voltage output: range from -10 to 10 V or -5 to 5 V,
10 Kohm minimum load.
Analog current output: range from 0 to 20 mA or 4 to 20 mA. The
maximum load is 300 Ω.
To achieve the serial connection, use a suitable shielded cable,
making sure to connect the shield to one of the two ends: to pin
2 if connected on the side of the instrument, to the ground if it is
connected on the opposite side.
Attention: do not connect the analog output to devices that are
switched on.
RS485:
The serial port RS485 (2-wire) is present in the model DAT 500/
RS485.
To achieve the serial connection, use a suitable shielded cable,
making sure to connect the shield to one of the two ends: to pin
8 if connected on the side of the instrument, to the ground if it is
connected on the opposite side.
The cable should not be channeled with the power cables.

DAT 400
FRONT PANEL OF THE INSTRUMENT
The DAT 500 has a bright 6-digit display, 4 status LEDs and four keys.
In this operating mode the display shows the weight and the LEDs indicate the status of weight and the
setpoints.
The set-up parameters are easily accessed and modified through the use of the three front buttons used
to select, edit, confirm and save the new settings.
DISPLAY
On the 6-digit display, it’s usually shown the scale weight. According to the various programming
procedures, the display is used for programming of the parameters to be stored in the memory, or the
messages that indicate the type of operation being carried out and help therefore the Operator in the
management and programming of the instrument.
LED INDICATORS
Below the display there are 4 LED indicators:
1 State of the logic output 1 (ON = closed contact OFF = open contact)
2 State of the logic output 2 (ON = closed contact OFF = open contact)
NET The displayed value is the net weight
0 IT indicates the condition of stable weight.

USING THE KEYBOARD
The instrument is programmed and controlled through the keyboard which has 4 keys, with the following
functions: The selection of one of the key functions is established automatically by the instrument accor-
ding to the operation in progress. In general, the management of the programming menus is done by
using the
SET

INFO DISPLAY
When the instrument is switched ON, you can test the display, then in sequence you can display the
identification code of the software and its version. Communication codes in the event of a request for
assistance.
ERRORS NOTIFICATION
In the operation mode, the display can report the following error codes.
 the weight applied to the load cell exceeds by more than 9 divisions the maximum capacity
of the weighing system.
O-L Signal of the load cells absent or outside of the measurement range mV/V.

Page 12
VIEWING, ZEROING THE WEIGHT AND SELF-CALIBRATION
After being calibrated, at the subsequent switches on, the display shows the current weight.
VIEWING THE NET WEIGHT/GROSS WEIGHT
Press the
0
key to toggle between the net weight and the gross weight and vice versa. The value
displayed is signaled by the LED NET (lit: net weight). If you have not entered the tare, the net weight
is equal to the gross weight.
In case of negative weight, it is displayed the minus sign before the most significant digit.
ZEROING, WEIGHT AND SELF-CALIBRATION
These two functions are performed by pressing
0
.
When the instrument is in the operation mode “Net” (“NET” LED on), the
0
key performs the self-
calibration.
When the instrument is in operation mode “Gross” (“NET” LED off), the
0
key clears the gross weight.
SELF-CALIBRATION
The execution of self-calibration is possible under the following conditions:
• Instrument under conditions of “Net” (NET” LED on).
• Positive gross weight.
• Gross weight not greater than the maximum capacity.
• Stable weight.
• Unstable weight. In this condition, we must distinguish two cases:
1. The weight stability control is enabled (the parameter “MOTION” (*) must be other than zero): the
command executed while the weight is unstable only has an effect if the weight stabilizes within 3
seconds from the moment the command was given.
2. The weight stability control is disabled (the parameter “MOTION” (*) is equal to zero): the executed
command takes effect immediately, even with unstable weight.
(*) The operating modes of the parameter “MOTION” are described at page 23
The self-calibration is retained in memory even after the power is turned off.
ZEROING
The reset command of the gross weight is used to correct for small zero shifts of the weighing system
during normal operation.
Normally these zero shifts are due to thermal drifts or to residues of material that accumulate on the
weighing system over the time.
To run the command, it is necessary that the instrument is under conditions of “Gross” (“NET” LED off)
and that the deviation of the weight with respect to the zero of the scale (the one performed with the
calibration of zero) does not exceed (in positive or negative) the number of divisions set in parameter
“0 BAND” (inside the PARAM menu; see page 24).

Page 13
The reset command of the gross weight does not run if there is even one of the following conditions:
• Unstable weight (with control of the stability of the weight enabled). In this case, the reset command
takes effect only if the weight stabilizes within 3 seconds or if the control of the weight stability is
disabled (parameter “MOTION “ equal to zero).
• Gross Weight greater (in positive or negative) than the number of divisions set in parameter “0
BAND” , when the setpoint of auto-calibration is not programmed.
The zero obtained with the resetting of the gross weight is retained in memory even after the power is
turned off.
The reset operation of the gross weight can be repeated several times, but the number of reset divisions
zero is added from time to time, so when the total exceeds the limit value set in parameter “0 BAND”,
the zero cannot be executed. In this case, it is necessary to calibrate the Zero.
Any auto-zero parameter setting when switching on (AUTO 0) reduces (or cancels, in the case of “AUTO
0”> “0 BAND”) the range of action of the reset command.
PEAK FUNCTION
The instrument continuously memorizes the peak value of the gross weight. The peak value is detected
at the same frequency of acquisition of the weight (see table on filters). In addition to visualization, the
peak value can be used in the following functions:
FUNCTION DESCRIPTION
LOGIC OUTPUT The setpoints can be set to have the peak value as a reference. (See the
procedure for setting the logic outputs operations).
SERIAL PORT Acquisition of the peak value (peak hold) through the CONTIN, AUTO, DE-
MAND, and MODBUS SLAVE protocols.
ANALOG OUTPUT The analog output value can assume the value of the peak (peak old). (See
the procedure for setting the analog output).
Press the
FUN
key and hold it for 3 seconds until the left of the display shows the letter “P”.

PROGRAMMING THE WEIGHT SETPOINTS
The set setpoint values are compared with the weight to drive its logic output. The comparison criterion
is established in the process of set-up of the logic I / O (see relevant paragraph).
To access the Setpoint setting, press the
SET
key and follow the instructions on the table below.
During the step of setting the setpoints, both outputs are disabled. If the setpoint value in memory is 0,
the corresponding output is never enabled, regardless of the set-up of the selected setpoints. When the
weight is not detectable or out of range, all outputs are disabled (contact open or closed depending
on the MODE; see the relevant chapter).
