You can operate the engine from the local control panel (see 4002−2, Local Control
Panel/ Local Display Unit (LDU-20).
The speed controller is part of the ECS. If the MCM-11 becomes defective, the fuel
command mode is selected automatically.
Note: The operator must not leave the local maneuvering stand. The operator
must regularly monitor the engine speed so that the fuel supply can be
immediately adjusted when necessary.
