Prepare for Engine Start after a Short Shut-down Period
(One or More Days)
1. Start Position
For the start position, the engine must be in the condition that follows:
D All components that had an overhaul are correctly assembled and installed. All
components that had an overhaul have had tests or checks to make sure that
they operate correctly.
D All devices, tools and materials are removed from the engine.
CAUTION
Damage Hazard: The ball valves 30-8605_E0_6 and 30-8605_E0_7
in the start air line must be open when the starting air shut-off
valve 30-4325_E0_1 is in the position CLOSED (see the Control
Diagram 4003−2).
2. Prepare for Operation
4) Do a check of the fluid levels of all the tanks in the engine systems (and the
leakage drain tanks).
5) Make sure that all the shut-off valves for the coolant water system and lubrication
oil system are in the correct position.
6) Open the air supply from the shipboard system to the control air supply A.
7) Open the 3/2-way valve 35-36HB at connection A1 and put the 3/2-way valve
35-36HA to the operation position (see Control Air Supply 4605−1).
8) Heat the lubrication oil to approximately 35_C (through the lube oil separator or
heaters in oil drain tank if installed).
9) Heat the cylinder coolant water to a minimum of 65_C.
10) Set to on the engine control system (ECS).
11) In the power supply box E85, set all circuit breakers to on.
12) Prepare the servo oil system (see 0130−1).
13) Start the pumps for the cylinder coolant water and bearing oil. Set the pressures
to their usual values (see the Operating Data Sheet 0250−1).
14) Prepare the cylinder lubrication system (see 0140−1).
15) Prepare the fuel system (see 0120−1).
16) Make sure that you correctly release all air from all systems.
17) In the LDU−20 (on the local control panel), get the MAIN page.
18) Get the EXHAUST VALVES page (see 4002−2, paragraph 3.1 and
paragraph 3.8).
19) Make sure that there is an air spring supply and make sure that all exhaust
valves are closed.
20) Manually open and close all exhaust valves until all air is released in the
hydraulic actuators as follows:
D In the column Exh. Valve pos., enter 1 in all the fields to manually open all
the exhaust valves.
D In the column Exh. Valve pos., enter 2 in all the fields to manually close all
the exhaust valves.
Note: You cannot start the engine if the exhaust valves are not fully closed.
