3.4 Control unit outputs
3.4.1 Outputs
The system has four digital OSSD short-circuit protected outputs that can be used individually (non safe) or can
be programmed as dual channel safety outputs (safe) in order to ensure the system safety level.
An output is activated when it switches from OFF to ON-state and it is deactivated when it switches from ON to
OFF-state.
3.4.2 Output functions
The function of each digital output must be programmed through the Inxpect Safety application.
The available functions are the following:
l
System diagnostic signal: switches the selected output to OFF-state when a system fault is detected.
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, receives a stop signal 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, receives a stop signal 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, receives a stop signal 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, receives a stop signal 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 manually restart
at least one detection field (Restart signal). It can be set as Standard or Pulsed.
o
If all the used detection fields are configured as Automatic restart (in Settings > Restart function), the
selected output is always in OFF-state;
o
If at least one detection field in use is configured as Manualor Safe manual restart (in Settings >
Restart function), the behavior depends on the option selected (see "Restart feedback signal option
settings" on the next page.
l
Static object detection feedback signal:switches the selected output to ON-state when at least one
sensor detects a static object in one of its detection fields. The selected output remains in ON-state for at
least 100 ms. If, at the same time, a moving target is detected in the detection field, the Static object
detection feedback signal will switch its selected output to OFF-state for the duration of the movement.
l
Detection signal group 1 or Detection signal group 2: switches the selected output to OFF-state when at
least one sensor detects a motion in a detection field belonging to the group (see "Detection signal group
settings" on the next page), receives a stop signal 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 group 1 or Detection signal group 2, a second OSSD is
automatically assigned to it to provide a safe signal.
Each output status can be retrieved by Fieldbus communication (if available).
