User parameters and maintenance settings for WECS-9520
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:
•
User parameters in USER
•
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.

Function
001
FQS
(Fuel quality setting)
The FQS can be set to adjust the maximum firing pres-
sure to the nominal value.
A negative correction angle will advance the injection
start and increase maximum pressure.
A positive correction angle will retard the injection start
and decrease maximum pressure.
002
VIT
(Variable injection timing)
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.
003
Inj. cut off
(Injection cut off)
Stops the fuel injection to a cylinder if necessary. The
WECS-9520 automatically activates a slowdown signal
to prevent engine overload. The exhaust valve contin-
ues to operate on the related cylinder.
NOTE:
If the fuel injection is stopped on more than
one cylinder, misfiring can cause dangerous
engine vibration. Make sure that the engine
speed is decreased sufficiently to prevent
high torsional vibration. If possible, do not set
to OFF cylinders that have a firing order of
one after the other.
