PROCEDURE
1
Refer to
11.2 List of usual values and safeguard settings - general
for the usual values for
operation.
2
In the control system, do a check of the data that follow:
•
Make sure that the values are in the permitted range
•
Make sure that there are no alarm signals.
3
If there are unusual values or alarm signals, find the cause and repair the fault.
4
Listen to the engine for unusual noise. If you hear unusual noise, find the cause and repair
the fault.
5
If you cannot find the cause of the unusual noise, stop the engine as soon as possible.
Find the cause and repair the fault.
6
Do daily the checks and the servicing that follow:
6.1
Do a check of the condensation collectors through the sight glasses of the SAC
and the water separator for free flow. If there is a blockage, clean the condensation
collector.
6.2
Release the unwanted air from the cooling water system.
7
Do a check of the exhaust gas for dark smoke. If there is dark smoke, find the cause and
repair the fault.
8
Do regular checks of the items that follow:
•
Fuel, oil and water levels
•
Temperatures of bearings, oil, water and exhaust gas
•
Oil pressure and control air pressure
•
Pressure difference of the oil filter
•
For a DF engine, also gas pressure.
9
If there are unusual operating values, find the cause and repair the fault.
10
Do regular checks of pipes for leaks. If there are leaks, find the cause and repair them.
11
Do a careful check of the dirty oil drain pipes for differences in temperature.
NOTE:
Different temperatures show a blockage in the pipes.
12
If there is an unusual temperature difference, remove the blockage of the pipe as soon as
possible.
13
Do weekly the checks and the servicing that follow:
13.1
Do a check of the quality of the cooling water, refer to the instructions of the inhibitor
manufacturer.
13.2
Do a careful check of the temperature of the pipe upstream of the starting air
valves. If a pipe is too hot, repair the related starting air valve.
13.3
Do a check of the fuel pump cover for oil leaks. If necessary, replace the O-ring.
13.4
Drain the bottle of the filter in the control air supply.
14
For a DF engine, do also the checks that follow:
14.1
Do regular checks (leak checks) of the gas piping system, refer to the related data
or documentation.
14.2
Do daily a check of the cylinder compression pressures on the LDU-20 CYLINDER
BALANCING DIESEL page or on the LDU-20 CYLINDER BALANCING GAS page.
14.3
If there is a drift that is too high or if there is a related alarm message, clean or
replace the related pressure transmitter, refer to the Maintenance Manual.
14.4
Do daily a check of the cylinder liner wall temperatures on the LDU-20
TEMPERATURES page.
