Pre-filling system
– if the option is activated, turning the key switch will open the solenoid
shortly to prefill the system with gas.
Ignition switch signal connected
4
–
This option can be unchecked to omit the ignition
switch signal connection. It is only allowed for vehicles, in which petrol injector fueling is
coupled with the ignition switch signal (fuelling of new petrol injectors is displayed upon
turning on the ignition switch and disappears when the ignition switch is turned off).
Otherwise, connect the ignition switch signal and keep the option active.
The
Car info
window lists the following groups of parameters:
Gas installation fitter
– contact details of the installation of a gas fitter.
Car info
– car data, which was mounted the gas installation.
Gas installation
–
general information about the components of the gas installation.
2.5. Signals, ingectors. LED switchboard
On the right side of the window there are the “Monitor” windows. The “Monitor” window shows the
following signals measured by the controller:
1.
Gas pressure
[bar]
–
LPG/CNG pressure value (the difference in the pressure regulator
pressure and the suction collector pressure)
2.
MAP pressure [bar]
– pressure inside the suction collector (absolute pressure value)
3.
Injection time [ms]
– petrol injection time
- P1
÷ P8 – Petrol injection time for Injector 1 ÷ 8
4.
Gas injection dose [ms]
– Gas injection time
- G1
÷ G8 – Gas injection time for Injector 1 ÷ 8
5.
Gas temperature[°C]
–
LPG temperature at the pressure regulator output
6.
Reducer temperature [°C]
–
liquid temperature at the reducer
7.
Internal temperature [°C]
–
internal temperature in controller
8.
Emulated engine temperature [°C]
– estimated engine temperature
9. Lambda 1 voltage [V]
–
voltage at the lambda probe 1
10.
Current type oxygen sensor 1 [mA]
–
current in the wide-band probe
11. Lambda 2 voltage [V]
–
voltage at the lambda probe 2
12.
Battery [V]
–
vo
ltage at the controller’s power supply
13. AUX voltage [V]
– the voltage of the AUX universal control output
14. RPM [rpm]
–
engine revolutions
15. Engine load [%]
–
current engine load value expressed in per cent.
All the above described signals are also visible on the oscilloscope. To turn off a given signal on the
oscilloscope, click on it. By clicking on the name of a given signal you can change its colour on the
oscilloscope.
Respective icons are displayed next to gas injectors. You can click any of the icons to disable/enable
gas injector represented by the icon (together with corresponding petrol injector). That way you can
easily diagnose mechanical failures of the injectors. The setting is temporary and deactivated
automatically after disconnection of the diagnostic application and cutting off the voltage with the key.
