2 GENERAL INFORMATION
The safety control unit F3SP-U4P-TGR has been designed to be used
with the dedicated light curtains. (Please refer to sec.11) It cannot be
connected to other light curtains.
The system conforms with the requirements for safety devices of type 4 in
compliance with the international standards stated e.g. IEC 61496-1.
However, the safety system category depends on the light curtain’s type as
follows:
Type 4 light curtain : Safety system category 4 (EN954-1)
Type 2 light curtain : Safety system category 2 (EN954-1)
This safety device is made up of a control unit protected by a plastic housing
so that it can be installed on a DIN/OMEGA rail; it has 32 removable screw
terminals to which it is possible to connect from 1 to 2 pairs of light curtains.
This control unit has the double ‘muting’ function. This function makes it
possible to obtain a “temporarily automatic suspension” of one or both safety
light curtains in order to allow, for instance, the objects passage without
stopping the machine.
The
‘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
5W) 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.
Do not install the control unit in the corrosive, flammable or explosive gas.
Do not use the cellular phone or transceivers near the control unit.
