Ex. No.
11 Operation: Manual reintegration
Operation in the following table shows the procedure:
■ Simulation of a wire-break at the load
■ Passivating an F-DO channel
■ Manual reintegration after removing the wire-break
Please observe the following:
■ A wire-break at F-DO is only recognized when the channel
is switched on.
■ Reintegration of an F-DO may take several minutes.
A more detailed description of the scenario, with overview image
on the hardware setup, is available at page 329.

State (*1)
30 Due to passivation of the channels the
TEST indicator light remains switched
on.
2 Restoring the connection 30 The state remains until the F-system recognizes
that the wire-break has been removed.
31 The F-system requests acknowledgement
for reintegration.
3 Press ACK_PASS_ACTUATOR 10 After acknowledgement by the user,
the F-DO channel is reintegrated.
