MENU : It is used for navigating the menus, selecting the relevant menu and making confirmation,
silencing the gas or tank alarms that occur on the monitoring screen.
EXIT : It is used to return to the main menu screen and leave the relevant menu.
UP : It is used to navigate the menus and increase the numerical values upwards.
DOWN : It is used to navigate in the menus, decrease the numerical values in the down direction,
switch the gas and tank menus on the monitoring screen.
POWER LED : Indicates that the device is powered.
TANK1 LED : Indicates Tank1 upper limit and lower limit level exceeding warnings. If it is red, it means the
upper limit, if it is green, it is the lower limit.
TANK2 LED : Indicates Tank2 upper limit and lower limit exceeding warnings. If it is red, it means the upper
limit, if it is green, it is the lower limit.
GAS LED : Indicates gas alarm status. It lights up red. If the detected signal value exceeds the set limit,
the led lights up and gives a warning.
