l Muting enable feedback signal: switches the selected output to ON-state in the following cases:
o
when a muting signal is received over the configured input and at least one group is in muting
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 detection 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 detection
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 detection
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 detection
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 detection field (Restart signal).
o
If all the used detection fields are configured as automatic restart prevention (in Settings > Restart
parameters), the dedicated output is always in OFF-state;
o
If at least one detection field in use is configured as manual or safe manual restart prevention (in
Settings > Restart parameters), the dedicated 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 detection field.
The ON-state lasts as long as the absence of motion within one or more detection field does and until
the restart signal is activated on the dedicated 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 a Restart
Feedback signal).
WARNING! To use SBV System Series for a category 3 safety system, both the channels of a safety
output must be connected to the safety system. Configuring a safety system with only one channel
safety output may result in serious injuries due to an output circuit fault and a failure of the machine
to stop.
The dual channel safety output is automatically obtained by the Inxpect Safety application and it only matches
the single OSSD outputs as follows:
l OSSD 1 with OSSD 2
l OSSD 3 with OSSD 4
In the dual channel safety output, the output status is the following:
l activated output (24 V dc): no motion detected and normal functioning
l deactivated output (0 V dc): motion detected in the detection field or failure detected in the system
