User Parameters and Maintenance Settings
1. General
The operator can get access to the user parameter settings without a password.
The operator can get access to the maintenance settings only with a password or a
key.
You use the Operator Interface of the remote control to change or set the parameters
in the WECS − 9520 as follows:
D User parameters in USER
D Maintenance settings in ADJUST.
For data about how to get these areas to change the related values, see the
documentation of the remote control manufacturer.
1.1 User Parameter
Parameter Function
FQS
(Fuel quality setting)
FQS can be set to adjust the maximum firing pressure to nominal
value.
A negative correction angle will advance the injection start and
increase max. pressure.
A positive correction angle will retard the injection start and
decrease maximum pressure.
VIT on/off VIT is usually set to on (shown as ON).
VIT can be set to off (shown as OFF) for running-in.
OFF means injection starts at the nominal angle and is not
related to the engine power.
Inj. cut off
(Injection cut off)
Can be used to stop fuel injection to a cylinder if necessary (e.g.
for liner/piston ring problems or damaged injection system).
The exhaust valve stays open in usual operation.
Inj. venting
(Injection venting)
Injection units of one cylinder, or all cylinders can be bled.
The rail valves will be activated at regular intervals for a specified
time. The servo oil service pump must be set to on.
This must be done before each engine start after a stop of some
hours.
Exv. A/M Cmd
(Exhaust valve auto/manual command)
Can be used to manually open and close an exhaust valve when
the engine has stopped.
Can also be used to do tests and venting e.g. after maintenance.
Conditions: The servo oil service pump must be set to on, to get
pressure in servo oil rail. The air spring pressure must be
available.
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 to, then do a check of the other valve.
Heavy Sea Mode Can be set to on in heavy sea. This function sets the fuel rail
pressure to a constant value and is not related to the engine
power. Pressure control becomes more stable. Set to off when
weather conditions become light and before manoeuvring.
Lubrication
(Supply rate)
Adjusts the necessary supply rate in steps of 0.1 g/kWh.
