If the watchdog fails, it is automatically taken out
of service and the objects controlled by the watchdog
will remain unchanged. The operator VDU can b directly
connected to one of the PUs. This enables continued
operator control. However, the watchdog monitoring
and control via the configuration bus, is not possible.
Monitoring is provided by means of LEDs on the crates.
Control is provided via manual switches in the crates,
which perform the same facilities as those provided
via the configuration bus.
Also, during installation the manual switches can be
used.
