FOREWORD
1. This manual is integral part of the shipment and it is supplied with the Product even if not listed in
the invoice.
This manual can also be sent during purchase negotiation on Buyer’s request provided that the
Buyer states end application of the Product.
Except as expressly request by the Buyer, only one copy of this manual may be attached to
shipments consisting of more than one unit of the Product.
Additional or updated copies of this document may be found on our web site at the following
address: www.s2tech.it
2. The Products, which are the subjects of this manual, are designed and manufactured for general use;
therefore, being not possible to specify limits of use for all applications, the Buyer shall introduce
safety measures in order to avoid personal injuries, damages to property or damages due to plants
stoppage, etc.
In case of use that can cause risk of damages, the Buyer shall immediately advise the Supplier in
order that it can suggest safety solutions or can decide to reject the order and not to deliver the
Product.
3. AN401 series of instruments are not certified instruments; it is Buyer’s responsibility to check
instrument suitability to the requirements of the specific application.
4. AN401 series of instruments, even when connected to transducers or other equipment, are only parts
of more complex systems and plants; they are sold in thousands per year, for the most different
applications which shall meet as many different norms that are not always known to the Supplier.
For these reasons, S2Tech is obliged to disclaim all responsibility concerning the use of the
instrument; however, a list of the most elementary and basic precautions for the correct use of the
instrument is given in this manual.
Besides, the need of a complete and specific insurance policy is highlighted, especially when
systems and machinery are to be installed in Countries like United States or Canada.
5. AN401 series of instruments are designed and manufactured by S2Tech conforming to the highest
quality standards; the instruments are rugged and designed to the highest possible safety and
reliability: limitations and precautions listed in this manual are aimed to draw Buyer’s attention to
the importance of avoiding damages.
6. During manufacturing process, AN401 series of instruments are submitted to several intermediate
tests and to a final test including performance test of all functions.
Electrical, temperature and mechanical sampling tests are periodically carried out to check
conformity of manufactured items to Product specifications.
For the overmentioned it is thereby certified that the delivered Product is
completely operating.

For longer connections, between transducer and instrument, verify that at
the transducer’s end You can measure a power supply voltage of 18 Vdc minimum.
To calibrate an AN401plus, connected with a PCX_ss magnetostrictive transducer, follow the
general procedures described in the “AN401plus quick start manual” or in chapter 5 of this manual.

On over mentioned figures (Fig.1a and Fig.1b) are shown connections to be used for
pushbuttons but it is possible to connect: relay, TTL lines, transistors, etc.
In order to light-on the LED emitters, internal to the opto-couplers, a voltage ranging from +12
to +28 Vdc must be supplied to each input.
Opto-coupler’s electrical characteristics:
Insulation: 200 V peak
Settling time: from 18 µS to 10 mSec
Release time: from 18 µS to 10 mSec
2.12 Earth connection (CE norms)
In order to obtain the maximum immunity to electrical disturbs, following are some
recommendations:
Power supply common must be connected to earth.
If AN401 plus is powered by a power supply separated from the rest of the machine,
connect the “EARTH” screw terminal to the nearest earth connection (avoid earth loops
or earth connections disturbed by high power devices).
When connecting signal lines from AN401 plus (analogue outputs, RS232 serial lines,
etc) please remember that they are referred to earth, in order to avoid the creation of
earth loops
Best condition is obtained when all commons (signal and power supply) are connected
to earth at the same point (star connection).
Avoid wiring any input/output cable, directed to AN 401, with high power cables.
If the application is free from electrical disturbs, Earth connection may be avoided.
