Display pages and structure
The information displayed is structured in three pages with subordinate views. You can change pages with
the Page switch.
1. The Measurement page consists of views that display measurement values such as voltages, current, oil
pressure and calculated values such as generator power and statistical data. The alarm list from the pre-
vious view is also shown there.
2. The Setpoints page consists of views with settings divided into groups, and a separate group for entering
the password.
3. The History log page shows the history log, where the last event is displayed first.
Note:
The Setpoints and History log pages are only accessible when Engineer is selected as the user (not User).
See the section Selecting language and user.

Values which are read from
the engine control unit
The instrument panel can read and generate
alarms for the following values from the engine
control unit:
• Engine speed.
• Oil pressure.
• Engine coolant temperature.
• Total operating time until next maintenance.
• Fuel level (only if the generator set has the
fuel level monitor option).
• Boost pressure.
• Intake temperature.
• Engine oil temperature.
Note:
Only alarms are written in the history log. Other
values that have been read from the engine con-
trol unit are not registered.

List of alarms from the coordinator
If the external expansion card has been installed (see position 10 in Components in the central electric unit),
the alarm can be used to control an external output, e.g. switching on a light or emitting an acoustic signal.
Alarm
Safety precaution
Description
AI1 Wrn
Alarm
Extra protection against low oil pressure. Activated at
2.4 bar.
AI1 Sd
Engine shutdown
Extra protection against low oil pressure. Activated at
2.0 bar.
AI2 Wrn
Alarm
Extra protection against high coolant temperature.
AI2 Sd
Engine shutdown
Extra protection against high coolant temperature.
AI3 Wrn
Alarm
Low fuel level warning, if the fuel level monitor op-
tion has been selected.
AI3 Sd
Engine shutdown
Low fuel level warning, if the fuel level monitor op-
tion has been selected.
Binary input
Configurable
Configurable alarm or engine shutdown for the inputs
for IL-NT, which are built-in in the instrument panel.
Binary input 1 is used for emergency stop and binary
input 2 for remote start.
IL-NT-BIO8
Configurable
Configurable alarm or engine shutdown for the inputs
for IL-NT-BIO8, if the expansion card has been se-
lected as an option.
Wrn Batt Volt
Alarm
The battery voltage is beneath the set limit values for
Batt Undervolt/Batt OverVolt.
ChargeAlt Fail
Alarm
Fault when the alternator tried to charge the battery.
Sd BatteryFlat
Engine shutdown
If the instrument panel is switched off during the start-
ing sequence of the engine due to a voltage drop, the
instrument panel will not try to start the engine again.
Instead, engine shutdown is activated.
Sd Start Fail
Engine shutdown
Starting fault. All start attempts have been carried out
but failed.
Wrn Stop Fail
Alarm
Shutdown fault. A shutdown fault occurs if the stop
button is pressed and the instrument panel is still read-
ing the values for voltage, rpm or oil pressure.
Sd Gen Lx >V (where x =
