the operations listed in the TEST &
ACTIVATION section .
In particular it is necessary to per-
form regular tests on board in
order to verify that the input devi-
ces are not faulted .
In the event of a switch-off of
the module or of the machine
it is necessary to repeat all the
operations listed in the TEST &
ACTIVATION section in order to
verify the integrity of the
external device system .
The safety module doesn’t require
internal maintenance: it must be
periodically cleaned - with plant
and module powered off - together
with all the connected devices,
removing dust, liquids and con-
densation .
APPLICATIONS
In the application samples when
S1 and S2 are operated, the safe-
ty module is enabled to close the
safety outputs (manual START) or
closes the safety outputs (automa-
tic START) .
In Fig . 3 and 5 a dual-channel
E-STOP is connected to the input
terminals . When the E-STOP is
not pushed, the safety outputs
are enabled to close . The safety
outputs are forced to open when
the E-STOP is pushed .
In Fig .4 and 6 a dual-channel
E-STOP is connected between the
supply terminals and the supply
source with the input terminals
short-circuited . When the E-STOP
is not pushed, the safety outputs
are enabled to close . The safety
outputs are forced to open when
the E-STOP is pushed .
