Commissioning and operation

6. Emergency operation unit:
The emergency operation control system
– Em – is conceived as a simple engine
speed and gearbox control system which
enables safe continuation of a trip in the
event of a failure in the electrical control
lever system.
The operating unit for the emergency
operation control system is integrated pre-
ferably near the control lever in the bridge
control console. For safe ship operation,
the keys on the front must be easily ac-
cessible. When the ignition is on, emerg-
ency operation can be activated using the
corresponding function keys. A green LED
indicates standby mode.
Operation is by means of six keys on the
front, which light up when a requested
mode is reached and thus return the
corresponding operating mode or actual
mode.
