Top of the Monitor pane is occupied by LED switchboard. Depending on the type of controller and
selected switch, in can be presented in two versions presented on figures 24-25.

There is a button on the LED switchboard for changing the fuel type. The operating condition is
signaled in case of LED-300 switches with the diode located next to the button. LED-300/401B and
LED-401 switches use button illumination instead. Basic indications:
 Off – petrol
 On – LPG/CNG
 Pulsing – auto mode
The chapter 4.1 contain a detailed description of operating mode of the controller.
Gas level is indicated by LED-300 switches with a line of 5 diodes, while LED-300/401B and LED-401
indicate it with 4 diodes arranged around the button. The minimum level (low fuel alarm) is indicated
by a red LED diode in LED-300 switches. In LED-300/401B and LED-401 switches, the status is
indicated by illuminating the button in red.
After right-clicking on the LED witch view, its settings window is displayed (Figure 26). Alternatively,
use the "Gas level indicator configuration" button on the "Gas controller settings" tab.
Basic operations include configuring the type of indicator and setting the voltage values, according to
which LED diodes will be lit to indicate the gas level on the switch panel (chapter 4.3 describes the
procedure for automatic setting of threshold voltage values). Having applied the minimum (back-up)
and maximum (full indication) voltage, you can use the AUTO button, which automatically calculates
and populates the remaining two voltage thresholds.
Select the type of gas level sensor and sensor characteristics. The current voltage read from the gas
level sensor is also displayed. With the "LED thresholds setting" window displayed, gas level change
