Adjustable parameters

NOTE: 

VODIA is used to adjust parameters in CIU

and EMS2. Some parameters require special authori-
zation.

Functions

Primary control mode

Selects which regulator is to be used when there is no
primary control switch.

Alternative position ............................. “Isochronal” or

                                            “droop” characteristic

Preset position ..................................... “Isochronous”

Control gradient 

(Droop)

Determines the engine speed droop to be used (gradi-
ent)

Min. value ........................................................... 0 %
Preset value ........................................................ 4 %
Max. value .......................................................... 8 %

Lamp test

This parameter determines if a lamp test is to be per-
formed when the system is started.

Alternative position ...............................  “Off” or “On”
Preset position ..................................................  “On”

Idle.

Sets the idle speed.

Min. value

 600 rpm

Preset value

 900 rpm

Max. value

1200 rpm

Pre-heating before ignition

Selects if pre-heating is activated directly when the ig-
nition is turned on. If the parameter “Off” has been se-
lected, pre-heating must be activated manually via the
ignition lock or pre-heater button.

Alternative position ...............................  “Off” or “On”
Preset position ................................................... “Off”

Connected to system voltage during
running/stop, EMS

Stops input data to the CIU unit connected to system
voltage at “run” or “stop”.

Preset position ................................................. “Stop”

Connected to system voltage during
running/stop, CIU

Stops input data to the CIU unit connected to system
voltage at “run” or “stop”.

Preset position ................................................. “Stop”

Idle voltage, CIU

Voltage of the throttle signal corresponding to idle at
the CIU unit.

Min. value ......................................................... 0.3 V
Preset value .................................................... 1.17 V
Max. value ........................................................ 1.9 V

Voltage max. rpm CIU

Voltage of the throttle signal corresponding to full
throttle at the CIU unit.

Min. value ......................................................... 1.9 V
Preset value ...................................................... 4.5 V
Max. value ........................................................ 4.7 V

Alarm limits

Alarm limit, high coolant temperature

a warning lamp is lit at this temperature.

Min. value ......................................................... 95 °C
Preset value .................................................... 104 °C
Max. value ...................................................... 103 °C
