The multidisc clutch, integrated into the gear in-
put shaft, permits the engaging and disengaging
of the epicyclic gear, and thus the generator, from
the main engine during operation.
An electronic control system with a RENK control-
ler ensures that the control signals to the main
electrical switchboard are identical to those for
the normal auxiliary generator sets. This applies to
ships with automatic synchronising and load shar-
ing, as well as to ships with manual switchboard
operation.

Internal control circuits and interlocking functions
between the epicyclic gear and the electronic
control box provide automatic control of the func-
tions necessary for the reliable operation and
protection of the BW III/RCF unit. If any monitored
value exceeds the normal operation limits, a warn-
ing or an alarm is given depending upon the ori-
gin, severity and the extent of deviation from the
permissible values. The cause of a warning or an
alarm is shown on a digital display.
