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
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
magnetic switch is connected to
the input terminals . When the gate
/ door is closed (NO contacts S1
and S2 closed), the safety outputs
are enabled to close . Pushing the
START button forces the safety
outputs to close . Opening the gate
/ door forces the safety outputs to
an open status .
In Fig . 4 and 6 the connections are
the same of Fig . 3 and 5, but the
module is configured for automatic
START: as soon as the gate / door
is closed (NO contacts S1, S2
closed), the safety outputs close .
Opening one gate / door forces the
safety outputs to an open status .
