SNS input

The controller also has an SNS input (high logic level (1) = 24 V) to check the correct functioning of the chip
that detects the status of the inputs.
NOTICE
If at least one input is connected, the SNS input "V+ (SNS)" and the GND input "V- (SNS)"
must also be connected.
4.2.9

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.
The function of each digital output must be programmed through the LBK Designer application.
The available functions are the following:
System diagnostic signal: switches the selected output to OFF-state when a system fault is detected
l
and switches all the OSSD related to detection signals, if any, to OFF-state.
Muting enable feedback signal: switches the selected output to ON-state in the following cases:
l
o when a muting signal is received over the configured input and at least one group is in muting
when a muting command is received through Fieldbus communication (if available) and at least
o
one sensor is in muting
Detection signal 1: (e.g. alarm signal) switches the selected output to OFF-state when a sensor detects
l
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.
Detection signal 2: switches the selected output to OFF-state when a sensor detects a motion in
l
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.
Detection signal 3: switches the selected output to OFF-state when a sensor detects a motion in
l
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.
Detection signal 4: switches the selected output to OFF-state when a sensor detects a motion in
l
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.
Fieldbus controlled (if available): allows the specific output to be set through the Fieldbus
l
communication.
Restart feedback signal: switches the selected output to ON-state when it is possible to restart at least
l
one detection field (Restart signal).
