SMS../CLS.. pair and the
ferromagnetic parts of the
machine closest to them.
To avoid mutual interactions
between different magnetic
sensors, when using more than
one pair of SMS../CLS.. on the
same application, every pair of
sensor-magnet must be placed at
least 50 mm far from the adjacent
sensor-magnet pair in any
direction.
At the end of the installation, the
machine installation procedure
must be carried out to check for
correct wiring and in particular to
check that the machine stop time
is less than the operator access to
the machine time, once the guard
is open.
NOTE.
The SMS../LD models make
available a signaling LED in series
to the N.C. contact: this contact is
8
not voltage free, but is polarized;
it needs and forces a voltage drop
when not operated. If the wires
are connected with the wrong
polarity, the LED is permanently
OFF (however the sensor still
works properly).
NOTE.
The EN 1088 standard states
that the magnetic type of
protection devices associated
to the guard cannot be easily
eluded through the use of
easily available instruments or
objects such as screws, nails,
pieces of metal, keys and
generally through objects or
tools related to the normal
machine working operations.
Based on the indication of the
standard, a multiple flow coded
magnet, such as the SMS..+
CLS.. systems, is a device that
is difficult to elude.
Nevertheless, due to the
impossibility of guaranteeing
non elusion through any
substituted magnetic actuator
for the coded magnetic unit, the
machine manufacturer must
carry out an installation that
includes mechanical obstacles
which do not allow the insertion
of a substitution actuator in
front of the sensor (with the
guard open).
