2. Engine Control Functions
The engine control lets you do the functions that follow:
D Engine start, running, reversing, maneuvering and stop
D Engine speed adjustment and control
D Partial safeguarding and monitoring the engine.
You do the function checks before you put the engine into operation (see paragraph 4
Engine control system checks).
Interlocks give protection against incorrect maneuvering.
The control media pressures are given in the Table 1:
Table 1: Alert Limits of System Oil Parameters
Control media
Pressures
Control air from board system 7 bar to 9 bar (see 1)
Control air from starting air system Maximum 25 to 30 bar (see 2)
Starting air from starting air bottle Maximum 25 to 30 bar
Main & crosshead bearing and piston
cooling oil
4.0 to 5.0 bar
Servo oil 100 to 200 bar
Notes to Table 1:
1) The pressure reducing valve 23HA is used to decrease the source pressure
(7 bar to 9 bar) to 6.5 bar.
2) The pressure reducing valve 19HA is used to decrease the source pressure
(25 to 30 bar) to 6 bar.
3. Engine Local Control
The engine can be operated at the local control panel (see also 4618−1).
This mode of operation can be chosen e.g. if there are failures in the electronic speed
control system or the remote control.
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.
3.1 Preparation
1) At the WECS−9520 manual control panel (see 4618−1), push the button LOCAL
MANUAL CONTROL (Local Control) to change control to the local manual
control.
3.2 Engine Start
