Item Parameter Function
004 Inj. venting (Injection bleed) This function lets you bleed the injector pipes and
ICUs. You can select one cylinder, or more than one
cylinder. If the fuel rail pressure is more than 250 bar,
the function will not operate. The process will continue
to operate for 30 seconds. After 30 seconds, the fields
automatically go back to the OFF condition until selec-
ted again.
005 Exv. A/M Cmds (Exhaust
valve auto/manual com-
mands)
This function lets you manually open and close an ex-
haust valve when the engine has stopped. The func-
tion can also be used to do tests of the exhaust valve.
The service pump must be set to ON to get pressure in
the servo oil rail. Air spring pressure must also be
available.
•
AUTO - usual condition. The exhaust valve is
closed when the engine is stopped.
•
MAN.OP - the exhaust valve opens. This func-
tion cannot keep the exhaust valve open be-
cause oil leaks through the orifice in the valve
actuator and the VCU. To keep the exhaust
valve open, you must use a special tool.
•
MAN.CL - the exhaust valve closes.
•
TURN.GEAR - the exhaust valve opens while
the crankshaft turns through the crank angle
sector for the selected exhaust valve.
006 Start Valves Checking
(Common start valves 1/2,
enable/disable)
To do checks of the control valves on the shut-off valve
for starting air.
Set a valve to OFF, then do a check of the other valve.
007 Heavy Sea Mode When set to ON, the Heavy Sea Mode changes some
functions in the WECS-9520. These changes make
sure of stable and safe engine operation during very
bad weather conditions. This function sets the fuel rail
pressure to a constant value of 700 bar and is not rela-
ted to the engine power. Pressure control becomes
more stable. Set to OFF when weather conditions be-
come light and before maneuvering.
All injectors are used for fuel injection for the full load
range. During usual operation at very low engine
loads, one injector is cut out to prevent black smoke.
Heavy sea mode prevents the failure of a cylinder if
one injector becomes unserviceable.
VIT is disabled. The VIT angle is set to 0° but the VIT
display shows ON.
008 Lubrication (Supply rate) Adjusts the applicable supply rate in steps of
0.05 g⁄kWh.
