￭ I/O parameters
For indication lamps, set the logic state of the corresponding digital output to Active high.
For digital inputs and outputs, set the diagnostic pulse setting to On.
Safety relay 1 settings are used to control the main contactor/breaker.

Sets the digital output connected to safety
relay 1.
DO X113:9 & X114:9Safety relay 1 outputSAFEIO.21
For the option +Q978, ABB has connected
the auxiliary safety relay(s) which controls
the main contactor/breaker to this digital
output at the factory. Make sure that this
value corresponds to the actual wiring. See
the circuit diagrams of the delivery.
To connect the safety relay to a certain
output signal of the FSO module, you must
set the same digital outputs in the output
parameter for that signal (see parameter
SBC.21).
Note: This digital output must always be
redundant. Otherwise the feedback signal
of the safety relay cannot be used (see
parameter SAFEIO.22). In the safety func-
tions described in this manual, there is only
one physical connection from the FSO I/O
to the auxiliary safety relay (DO X114:9),
but in this parameter setting, the output
must be redundant. Do not use digital out-
put DO X113:9 for any other purpose.

For the option +Q978, ABB has configured
the auxiliary safety relay(s) and the main
contactor/breaker to this digital input at the
factory. Make sure that this value corres-
ponds to the actual wiring. See the circuit
diagrams of the delivery.

Mechanically linked NC contacts: Feedback
of the safety relay is NC (normally closed,
that is, inverted state compared with the
relay). Make sure that the value is Mechan-
ically linked NC contacts.

For the option +Q978, ABB has configured
the emergency stop button to this digital
