4.2. LED-300/401B and LED-401 switchboard
Fig. 59 LED-300/401B / LED-401 switchboard
LED-300/401B and LED-401 LED switchboard consists of:
Gas level indicator
–
four diodes in a circular arrangement showing the current gas level in the
tank. Four green diodes indicate that the tank is full.
Button (with AC logo)
–
used for fuel switching and indicate current operating conditions:
Off (PETROL mode)
– indication that the engine is fueled with petrol,
Slow blinking (once per second
– AUTO mode)
– the engine is started on petrol and
switches to autogas when the set parameters are achieved
Normal blinking (twice per second, no acoustic signals
–AUTO mode)
– the engine is
started on petrol and switches to autogas when the set parameters are achieved. The
system switches the engine to gas fueling. The state may continue for up to 10 seconds,
depending on engine working parameters at the moment and controller settings.
Fast blinking (4 times per second, with acoustic signals
–EMERGENCY mode)
– system
error prevents gas fueling, e.g. empty gas tank, LPG installation fault; the engine runs on
petrol
Continuous light in white (GAS mode)
- the engine is supplied with autogas
Continuous light in red
– operation on gas, low fuel level
If the controller is connected to the LED-401 switch, additional functions are available:
The user can adjust LED brightness (4 brightness levels)
– if automatic LED brightness is
Off,
The user can adjust the volume of buzzer installed inside the switch,
The switch can be installed in any position to allow comfortable control of gas level
indication and the reference position is the position of the buzzer,
Automatic detection of the connected switch. If LED-401 is connected, the application also
shows LED-401.
4.3. Automatic calibration of LPG level indicator
The automatic calibration of LPG level indicator should be carried out when an empty tank is being
filled with gas. The indicator type should already be set, but, if necessary, the procedure itself may
change its type, e.g. from ascending to descending.
The calibration procedure is as follows:
Press and maintain the switchboard push button,
Switch off the ignition switch (during to three seconds after pressing push button),
Depress the button when the switch initiates level indicator calibration.
