An output is activated when it switches from OFF to ON-state and it is deactivated when it switches from ON to
OFF-state.
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* and at least one group is in
muting
l
Detection signal 1
: (e.g. alarm signal) switches the selected output to OFF-state when a sensor detects
motion in detection field 1, or when a stop signal is received from the related input. 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
: (e.g. warning signal) switches the selected output to OFF-state when a sensor detects a
motion in detection field 2, or when a stop signal is received from the related input. 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
Fieldbus controlled
: allows setting the specific output through the Fieldbus communication*.
l
Restart Feedback signal
: switches the selected output to ON-state when it is possible to restart the system
safely using the dedicated input (Restart signal). In case of:
o
automatic restart prevention, the dedicated output is always in OFF-state;
o
manual restart prevention, the dedicated output remains in OFF-state as long as a movement is detected
in the monitored area; then it is activated (ON-state) and the ON-state lasts as long as the entire
monitored area is free of movements and until the Restart Signal is activated on the dedicated input;
o
safe manual restart prevention, the dedicated output remains in OFF-state as long as a movement is
detected in the monitored area; then it is activated (ON-state) if the entire monitored area is free of
movements (each detection field for its consecutive Restart timeout). The ON-state lasts as long as the
area remains free of movements and until the Restart Signal is activated on the dedicated input.
Each output status can be retrieved by Fieldbus communication*.
Note*
: only if the controller supports the safety communication on the Fieldbus interface. For details, see "Safety Fieldbus
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 and muting enable feedback), or
l
each output as a single output (e.g. system diagnostic, muting enable feedback and two Fieldbus controlled
outputs).
The dual channel safety output is automatically obtained by the Inxpect Safety application and it matches the
single OSSD outputs only 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
Idle signal is 24 V dc, periodically shortly pulsed to 0 V (pulses are not synchronous) for the receiver to detect
shortcut to either 0 V or 24 V.
