Before connecting the equipment to the supply voltage, read the following Safety
Guidelines, in order to protect yourself and the equipment from any serious
danger.
• Read all the instructions for the installation, before connecting the supply
voltage and alarm cable.
• Follow all the instructions and precautions concerning the equipment.
Immediately disconnect the supply voltage and alarm cable in the following cases:
• If the connecting cables or the connectors are worn out or damaged.
• If liquid is present, even in the form of moisture, inside the equipment.
• If the case of the equipment shows damage or breaks.
• If it is felt that the equipment requires maintenance or repair.
tWarning: before cleaning the mixer wagon with high pressure jets of water,
disconnect the connection cables, remove the equipment from the mixer
wagon and protect the connectors of the connection cables from water
infiltration. Also take great care to see that the load cells, junction box, alarm
device and other options are not exposed to direct jets of water. y
tWarning: before carrying out welding operations on the mixer wagon, always
disconnect the connection cables. In order to prevent the welding current
from passing through the load cells, it is necessary to short circuit the body of
the load cells with a cable having a suitable cross section, besides positioning
the pliers of mass as close as possible to the welding point. y
tWarning: if, during the operation, the display shows the blinking symbol b
or the writings [ LOWBAT ] or [ H.BAT ] or [ OV.LOAD ] or [ ERR-xx ], refer to
the Appendix A - Error Codes. y

2.6 - GENERAL NOTES ON CALIBRATION
The accuracy of a weighing system is determined not only by the errors caused by
the different "Sensitivity" existing among load cells even of the same model and
among machines of the same model, but even by the errors caused by the
imperfect installation of the load cells (the imperfect alignment of the TOP) and
by the imperfection of the mechanical structure of the mixer wagon. Such errors
can be eliminated only performing the Calibration by Sample Weight. Anyway, it
is possible to calibrate the equipment with a good accuracy using the other
Calibration Procedures.
It is absolutely necessary to perform a Calibration Procedure when using the
equipment with load cells of a model different from the one with which it had
been previously calibrated.
Before performing a Calibration Procedure, check if the Unit of measure shown on
the display is the wished one.

15Chapter 2
TECHNICAL GUIDE
2.6.1 - CALIBRATION BY PARAMETERS [ CODE 33 ]
The Calibration by Parameters Procedure allows to calibrate the equipment for all
the type of load cells, even not listed in Table F too.
By the Calibration by Parameters Procedure it is sufficient to program:
• The number of load cells connected with the equipment.
• The Rated Capacity of the single load cell, in the setted Unit.
• The Rated Sensitivity in mV/V of the single load cells.
To select the Calibration by Parameters Procedure, operate as described here
below:
1. In the Access Code Page program the Code 33 and confirm by the key OK.
The display shows alternatively the writings [ LOAD ], [ CELLS ] and [ x ],
where xrepresents the number of connected load cells 1... 8.
2. To program the number of load cells use the keys qor z.
3. To confirm press the key OK.
The display shows alternatively the writings [ CAP. ] and [ xxxxx ], where x
represents the Rated Capacity value of the single load cell
(max. 20,000kg/44,000lb).
4. To program the value of the Rated Capacity use the keys qand z(e), or
press the key 2FN and use the Alphanumeric Writing.
5. To confirm press the key OK.
The display shows alternatively the writings [ SENS. ] and [x.xxxx], where x
represents the Rated Sensitivity value of the single load cell
(0.1000 ... 6.0000 mV/V).
6. To program the Rated Sensitivity value use the keys qand z(e), or press
the key 2FN and use the Alphanumeric Writing.
7. To confirm press the key OK.
The display shows the writing [ DONE ] and the equipment returns to the
Access Code Page.

2.6.2 - CALIBRATION BY CODES [ CODE 34 ]
The Calibration by Codes Procedure allows to calibrate the equipment in a very
simple and prompt way. Selecting this Calibration Procedure it is sufficient to
program the Code corresponding to the model and to the quantity of connected
load cells, according to the indications of Table F.
rCaution: if in Table F the model or the number of connected load cells is not
indicated, it is not possible to use the Calibration by Codes, but it is necessary
to use the Calibration by Parameters Procedure. r
To select the Calibration by Codes Procedure, operate as described here below:
1. In the Access Code Page program the Code 34 and confirm by the key OK.
The display shows alternatively the writings [ CODE ] and [ xx ], where x
represents the Code of the load cells to be set.
2. To program the wished Code use the keys qor z(e).
3. To confirm press the key OK.
The equipment returns to the Access Code Page.
