2 GENERAL INFORMATION AND MAIN APPLICATIONS.
The single beam safety control unit F3SP-U3P-TGR has been designed and
produced to meet the need to protect persons in areas where it is necessary
to guarantee the safety of the operator using machinery, robots or in general
automation systems which are considered dangerous or subject to casual or
undesired access to unsafe parts.
The system conforms with the requirements for safety devices of type 2 in
compliance with international standards, e.g. IEC 61496 1-2.
This safety device is made up of a control unit protected by a plastic
container so that it can be installed on a DIN/OMEGA guide; it has 16
removable screw terminals to which it is possible to connect from 1 to 2 pairs
of photocells.
This version of the single beam safety control unit has the
‘muting’ function
integrated, by means of this function it is possible to connect or disconnect
one or more pairs of photocells in order to allow - for instance - the material
passage without stopping the machine.
The additional
‘override’ function enables system, to keep the output relays
closed even with intruded rays to enable material transport after a system
shutdown.
Both
muting and override functions represent a system that require additional
precautions to limit the reduction of the safety level. This precautions have to
be considered carefully.
The
muting and override function is available by simply connecting the F39-
A11 muting lamp (or similar yellow bulb type lamp for 24VDC / 3W to 7 W)
supplied separately.
The presence of a limb or an object interrupting a beam causes the opening
of the safety outputs and the consequent stopping of the connected machine.
It is necessary for the safety sensors to be connected in the right position in
such a way that there isn’t any possibility to climb over or defeat the system.
