of the person in charge of such
evaluations.
Operator safety can be
compromised by the lack of
regular inspections or
maintenance, or if they are carried
out incorrectly, or by non
specialized personnel, or at lower
intervals than prescribed.
Regular inspections consist of
carrying out an inspection of the
wiring, of the installation, of the
tightening and of the integrity of
the SMS../CLS.. pair, and in
repeating - for each sensor /
magnetic unit pair - all the
operations concerning the
machine start-up procedure.
Maintenance consists of a regular
cleaning of the sensor and the
magnetic unit and of all the
connected devices: dust and other
substances must be removed
from the devices and it must be
dried of liquids or any
condensation. All cleaning
operations must be carried out
whilst the machine is rigorously
not powered.

TECHNICAL DATA
All the distances involved are
referred to a sample CLS.. device,
with SMS../CLS.. pairs mounted
far away from other magnetic
parts or devices, and with SMS..
frontally operated (see Fig. 4).
The Operating Distance (D-ON)
is the one in which all safety
10
contacts have switched their
status.
The Release Distance (D-OFF) is
the one in which, when the
magnetic unit moves away from
the sensor, one contact releases
returning to the rest position, while
the other (if any) is still switched.
The Reset distance (D-RESET)
is the one in which, when the
magnetic unit moves away from
the sensor, all safety contacts
have released and return to the
rest position.
The letters V, I, P, refer to the
Voltage, Current, Power that
characterizes the output contacts
of the sensors.
In Table 2 is summarized for each
SMS.. model the corresponding
CLS.. actuating magnet and the
maximum safety category of the
whole safety-related part of the
machine in which the sensor /
magnet pair can be employed.
NOTE.
The technical data of this manual
are applicable also to the SMS..
models with different cable length.
