CONNECTION DIAGRAM
RS-NAGU.12 could be used together with safety light barriers and safety
light curtains with safety category 2 which have a selftest. The RS-NAGU.12
is used for muting of safety light barriers and safety light curtains. So that
material - transport to or from a machine can be done. Applications can be
found in the automotive industry, packaging machines or at highly
automated production systems. The differentiation between human beings
and material flow is done with up to four muting sensors or two safety light
barriers. Inductive sensors or mechanical switches can also be used as
muting sensors. After connection as per application guide, the device will be
ready as soon as the power LED and channel are illuminated. If LED
channel 1 is blinking, a fault exists or a wrong connection has been made.
In ready condition the RS-NAGU.12 can be started by pushing the start
key. If it cannot be started, then at least one of the muting sensors is
blocked or not connected correctly. If a muting sensor is blocked by material
supply, a muting can be initiated by actuation of the key switch. If the light
barrier is interrupted after a muting cycle, RS-NAGU.12 can be activated by
pushing the start key after the failure has been fixed. As soon
as muting sensors 1 and 2, respectively 3 and 4 will be activated within 3
sec.,
the RS-NAGU.12 will initiate a muting cycle. Interruption of the light barrier
will
not cause a stop of the machine. If 3 of the 4 muting sensors are
deactivated,
the muting cycle will end after 0.25 sec.
