3.4 Reversing
1) In the LDU−20, get the MAIN page.
2) Turn the rotary button to select 30% fuel injection quantity.
3) Push the button START AHD or START AST until the engine operates in the
applicable direction.
Note: On ships under way, this procedure can be some minutes, because the
flow of water has an effect on the propeller.
You can also use the ECR manual control panel to do the reversing procedure given
above.
You can use the buttons and rotary button only at the related active control stand.
3.5 Installations with Controllable Pitch Propeller
For data about installations with controllable pitch propellers, refer to the
documentation of the propeller manufacturer.
3.6 Installations with Clutch Couplings
You must not disengage clutch couplings while the engine operates.
You must make sure that the couplings are engaged before you start the engine.
4. Increase Power after Release to Sea Speed and
Decrease
You must only increase and decrease the engine load during a given time period. This
time period is usually between 40 minutes to 45 minutes between full maneuvering
and service power. The time period must not be less than that given as follows:
D For an increase in engine load, not less than 30 minutes
D For a decrease in engine load, not less than 15 minutes.
You use the related devices in the engine room to manually increase and decrease
the engine load as follows:
For fixed pitch propeller installations:
D Speed setting.
For controllable pitch propeller installations:
D Speed setting
D Propeller pitch setting lever
D Speed and propeller pitch setting lever (combinator).
The time limits given above for speed and power are not applicable if a faster
decrease of engine load is necessary when:
D There are critical alarm conditions in the engine room
D A shut-down or slow-down signal is activated.
5. Emergency Maneuver
The safety of the vessel is very important. If an emergency manoeuvre is necessary,
all the limits specified in paragraphs 2, 3 and 4 are not applicable, i.e. you can use the
the full power of the engine.
