1.2 Foreword
✔The aim of this manual is to provide the operator, through the use of
text and illustrations, with essential information regarding the
installation, safe operation and maintenance of the weighing system.
✔This manual must be kept in a safe place where it is readily available
for consultation. Always observe the instructions contained in the
manual!
✔The safe operation of the system is the responsibility of the operator,
who must have a thorough knowledge of the system.
✔The user is responsible for ensuring that the installation conforms to
the applicable regulations.
✔The equipment must be installed by specialised personnel who have
read and understood this manual.
✔"Specialised personnel" means any personnel who, by virtue of the
training they have received and their professional experience, have
been explicitly authorised by the "System safety supervisor" to install,
operate and maintain the system.
✔In the event of any problems, contact your nearest Service Centre.
✔Any attempt on the part of unauthorised personnel to dismantle or
modify the terminal is prohibited; any such attempt shall invalidate the
warranty and release the manufacturer from all liability for any injury
or damage.
✔Alteration or removal of the data plates and seals is strictly prohibited;
check that all plates and seals are present and legible, if not contact
After-Sales Service.
✔The manufacturer shall not be liable for any damages caused by
incorrect handling of the terminal.
✔The information and illustrations contained in this manual were up to
date at the time of publication.
✔The Manufacturer is committed to a policy of continuous product
improvement and system components may therefore be subject to
modification.
✔All the technical information contained in this manual remains the

form, including publication in computerised form or on the World Wide
Web, without the explicit written permission of the manufacturer.
✔This manual may not be used for purposes other than those directly
related to the installation, operation and maintenance of the terminal.
✔In order to more clearly illustrate certain maintenance or adjustment
operations, some of the illustrations in this manual show the weighing
system with the safety guards removed. Under no circumstances may
the system be operated in these conditions. Do not operate the
system in these conditions under any circumstances whatsoever, but
remove the safety guards for the time strictly required to carry out the
required repairs or maintenance then fit them back in place.

1.4 Description of the terminal
Digital weight indicator mod. D70 allows highly accurate and reliable
weighing operations to be carried out.
This terminal is available in two versions called D70A and D70B. The
D70A version is particularly suitable for use in the industrial and
commercial weighing sectors since its configuration allows it to be easily
installed on weighing platforms. The D70B version is a terminal for use
in plants with the least possible amount of equipment for installation in
electric panels (concrete mixing, batching plants, etc.).
The terminal can also be used in the piece counter mode.
Certain of the characteristics that distinguish the two versions of the
terminal are listed below:
Version D70A Version D70B
✔✔ connection to a scale with
analogue cells (up to twelve
350 Ohm cells);
connection to a scale with
analogue cells (up to four 350
Ohm cells); ✔✔ 2 serial outputs with RS232
and RS232/422/485 output
standards;
2 serial outputs with RS232
and RS232/422/485 output
standards;
✔ ✔a12V power supply by means
of an external adapter (85-265
VAC);
1 analogue output with (0 - 10)
V voltage and (0 (4) - 20) mA
current;
✔
✔mains power supply (85-265
VAC);
rechargeable internal batteries
can be used for operation in the
absence of mains power. ✔the terminal can be powered by
12 V external batteries or an
external adapter.
