1. IMPORTANT USER INFORMATION
•The symbol is intended to alert the user of a non-insultated voltage souce within the
product area that is sufficiently high to constitute a risk of electric shock to persons.
•The symbol is intended to alert the user of important operating and maintenance
(servicing) instructions.
•Dixell Srl reserves the right to modify this user’s manual at any time without prior notice. The
documentation can be downloaded from the website www.fulltouch.info even prior to purchase.
•This manual is an integral part of the product and must always be kept near the device for easy
and quick reference. The product cannot be used as a safety device. Please read this manual
very carfully be sure you understand the information provided before using the device.
•Verify that the power supply voltage is correct before connecting the device. Do not expose it to
water or humidity: use the controller only within the operating limits, avoiding suddentemperature
changes and high atmospheric humidity in order to prevent condensation from forming.
Recommendations: disconnect all the electrical connections before performing any maintenance
task; insert the probewhere it cannot be reached bythe End User; the device must not be opened;
consider the maximum current that can be applied to each relay; make sure that the wires of the
probes, of the loads and the electical power supply cables are sufficiently separated from each
other, without crossing or intertwining. In case of applications in industrial environments, it may
be useful to use the main filters as well as the inductive loads.
•The customer shall bear full responsibility and risk for product configuration in order to achieve
the the final installation of the equipment/system. Upon the customer's request and following a
specific agreement, Dixell Srl may be present during the start-up of the final machine/application,
as a consultant, however, under no circumstances can the company be held responsible for the
correct operation of the final equipment/system.
•Since Dixell products are part of a high-level technology, a qualification and a
configuration/programming/commissioning stage is required to best use them. Otherwise, these
products may malfunction and Dixell cannot be held responsible. The product must not be used
in any way that differs from that stipulated in the documentation.
•The device must always be installed inside an electrical panel that can only be accessed by
authorised personnel. For safety purposes, the keyboard must be the only part that can be
reached.
•The electrical wiring connections must never be modify while the device is being used.

1592040000 XR70T EN v1.1 2019.07.09 XR70T 6/40
•It is good practice to bear in mind the following indications for all Dixell products:
oPrevent the electronic circuits from getting wet as contact made with water, humidity or any
other type of liquid can damage them. Comply with the temperature and humidity limits
specified in the manual in order to store the product correctly.
oThe device must not be installed in particularly hot environments as high temperatures can
damage the electronic circuits and/or plastic components forming part of the casing. Comply
with the temperature and humidity limits specified in the manual in order to store the product
correctly.
oUnder no circumstances is the device to be opened - the user does not need any internal
component. Please contact qualified service personnel for any assistance.
oPrevent the device from being dropped, knocked or shaken as either can cause irreparable
damage.
oDo not clean the device with corrosive chemical products, solvents or aggressive detergents.
oThe device must not be used in applications that differ from that specified in the following
document.
•Separate the power supply of the device from the rest of the electrical devices connected
inside the electrical panel. The secondary of the transformer must never be connected to
the earth.
•Dixell Srl reserves the right to change the components of its products, even without notice,
ensuring the same and unchanged functionality."
