CONNECTION DIAGRAM
NAGU 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´s and channel 1 and channel 2 are
illuminated. If LED´s channel1/2 are blinking, a fault exists or a wrong
connection has been made. In ready condition the RS-NAGU 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 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 will initiate a muting cycle. Muting takes place
so long the inputs of both groups of muting sensors are in active state plus
0,25s time-delay.
RS-NAGU.1: 3 electronic safety semiconductor outputs.
RS-NAGU 2f: 3 normally open safety, 3 normally open signal outputs
(release,
and safety light barrier)
RS-NAGU (housing with detachable terminal strips) also this unit is
available
