o
when a muting command is received through Fieldbus communication (if
available) and at least one sensor is in muting
l
Detection signal 1
: (e.g. alarm signal) switches the selected output to OFF-state
when a sensor detects a motion in protective field 1, when a stop signal is received
from the related input or when there is a system failure. The selected output remains
in OFF-state for at least 100 ms.
Note
: when an OSSD is configured as detection signal 1, a second OSSD is
automatically assigned to it to provide a safe signal.
l
Detection signal 2
: switches the selected output to OFF-state when a sensor
detects a motion in protective field 2, when a stop signal is received from the related
input or when there is a system failure. The selected output remains in OFF-state for
at least 100 ms.
Note
: when an OSSD is configured as detection signal 2, a second OSSD is
automatically assigned to it to provide a safe signal.
l
Detection signal 3
: switches the selected output to OFF-state when a sensor
detects a motion in protective field 3 or when a stop signal is received from the
related input or when there is a system failure. The selected output remains in OFF-
state for at least 100 ms.
Note
: when an OSSD is configured as detection signal 3, a second OSSD is
automatically assigned to it to provide a safe signal.
l
Detection signal 4
: switches the selected output to OFF-state when a sensor
detects a motion in protective field 4 or when a stop signal is received from the
related input or when there is a system failure. The selected output remains in OFF-
state for at least 100 ms.
Note
: when an OSSD is configured as detection signal 4, a second OSSD is
automatically assigned to it to provide a safe signal.
l
Fieldbus controlled
(if available): allows the specific output to be set through the
Fieldbus communication.
l
Restart Feedback signal
: switches the selected output to ON-state when it is
possible to restart at least one protective field (Restart signal).
o
If all the used protective fields are configured as automatic restart prevention
(in
Settings
>
Restart parameters
), the selected output is always in OFF-
state;
o
If at least one protective field in use is configured as manual or safe manual
restart prevention (in
Settings
>
Restart parameters
), the selected output
remains in OFF-state as long as motion is detected; then it is activated (ON-
state) if there is no more motion within at least one protective field. The ON-
state lasts as long as the absence of motion within one or more protective
field does and until the restart signal is activated on the selected input.
Each output status can be retrieved by Fieldbus communication (if available).
The system installer can decide to configure the system as follows:
l
two dual channel safety outputs (e.g.
Detection signal 1
and
Detection signal 2
,
usually alarm and warning signals), or
l
one dual channel safety output (e.g.
Detection signal 1
) and two single channel
output (e.g.
System diagnostic signal
and
Muting enable feedback signal
), or
l
each output as a single output (e.g.
System diagnostic signal
,
Muting enable
feedback signal
and
Restart Feedback signal
).
