Mode of Operation
The safety modules NES02D
and NES13D monitor E-Stop
pushbutton and limit swich
devices, according to
98/37/CE Machinery Direc-
tive.
If the unit is correctly sup-
plied and the input terminals
are closed (i.e. E-Stop not
pushed), the module is
enabled to close the safety
outputs and the external
contactors can be ener-
gized.
When the input terminals are
open (i.e. E-Stop pushed)
the module is not enabled to
close the safety outputs and
the external contactors can
not be energized.
Automatic START
Provided that the terminals
X1 and X2 (NES02...A) or
S33 and S34 (NES13...A) are
connected, the safety out-
puts close and the auxiliary
output opens (NES13...A) as
soon as both S1 and S2
switches are closed.
The relevant CH1 and CH2
LED turn on.
Releasing even one input
contact (S1 and/or S2)
forces immediately the safe-
ty outputs to open and the
auxiliary output (NES13...A)
to close.
A new operating cycle is
possible only after releasing
both input contacts and then
operating them again.
Manual START
Provided that both S1 and
S2 switches are closed, the
safety outputs close and the
auxiliary
output opens
(NES13...A) as soon as the
NO START pushbutton is
pushed [connecting X1 and
X2 (NES02...A) or S33 and
S34 (NES13...A)]
A new operating cycle is
possible only after releasing
both input contacts, closing
them again and pushing the
START button.
Monitored manual START
The monitored manual
START versions (NES...C)
work as described in the
previous paragraph (Manual
START) except for a mini-
mum delay of 500 ms from
the closed status of the
input contacts to the push-
ing of the START button.
If the input terminals get
closed with the START
switch already closed, the
safety outputs don't close
and the auxiliary doesn't
open (NES13...C): it is nec-
essary to release the START
button and the input con-
tacts before starting a new
cycle, then operate the input
contacts and finally, after at
least 500 ms, operate the
START button.
So if the NO START button
gets welded, the outputs
don't close anymore.
