FUNCTION
The safety module
NLG13D724..
is designed to be employed in
safety circuits to control
ElectroSensitive Protective
Equipments (ESPE) with static
PNP outputs or relay outputs
according to 98/37/EC and
2006/42/EC Machinery Directives.
NOTE
The input terminals of the module
are intended to be:
“
operated
” when the light beams
are not interrupted, the ESPE and
the module are correctly supplied
and there are not fault conditions
of the safety system: the ESPE
outputs are ON, the module is
enabled to close the safety out-
puts and the external contactors
can be energized.
“
released
” when the light beams
are interrupted, or the ESPE
and/or the module are not correc-
tly supplied or there are fault con-
ditions of the safety system: the
ESPE outputs are OFF, the
module is not enabled to close
the safety outputs and the exter-
nal contactors cannot be energi-
zed.
INSTALLATION
W
ARNING
- The safety module must be
installed following the standards
in force in the country of use,
when the machine is not powe-
red and with no dangers for the
operator, on the machine’s elec-
trical board in a dry and clean
place (minimum protection
degree: IP54), fixed on the spe-
cial DIN rail.
- If the safety module is tampered
with, it can not ensure the safety
of the operator any more and
the warranty is void.
- To avoid interference due to
coupling, run the connecting
