LED-401 switchboard view
LED-401 switchboard features the following elements:
LED circle
– four LEDs in the form of a circle, which indicate the current LPG level in the tank.
Four green LEDs indicate a full tank.
AC logo button
– enables fuel switchover and indicates the current mode of operation:
•
darkened – the vehicle is running on petrol;
•
flashes slowly (once per second) – the engine is running on petrol, once the set
parameters have been achieved, the system will automatically switchover to LPG;
•
flashes normally (twice per second) with no sound signals – the system is switching over
to LPG; this can last up to 10 seconds depending on the current parameters of the engine;
•
flashes rapidly (4 times per second) and emits sound signals – controller’s error (e.g.
shutdown due to an empty LPG tank);
•
backlit in white – the vehicle is running on LPG;
•
backlit in red – the vehicle is running on LPG, but the LPG tank is almost empty.
The following functionalities are accessible, when LED-401 switchboard is connected to STAG 400
controller:
•
Sound level adjustment for the buzzer installed inside the switch (4 selectable sound
levels);
•
Brightness adjustment for the LEDs (4 selectable brightness levels) – the function is
inactive when „Auto brightness adjust.” is ON;
•
LED switchboard orientation adjustment in order to ensure correct visualisation of the
LPG level indication, the buzzer installation location being the reference point;
•
Selectable activation of automatic adjustment of switch LEDs brightness depending on
the ambient light;
•
Automatic identification of the type of connected LED switchboard; a connected LED-401
switchboard is recognised by the application as LED-401.
