4. Microswitch-1 is pressed. The firebox flap is raised when it presses the first microswitch, a bunch with a blue arrow
appears on the control unit screen (pictured in the boiler, see picture a), and information I5 is in HISTORY. The boiler
conveyors stop working while the microswitch-1 is pressed.
5. Microswitch-1 and microswitch-2 are pressed. The firebox flap is raised when it presses the first and second
microswitches, a bunch with a red arrow appears on the control unit screen (pictured in the boiler, see picture b) and an
error is displayed "E119 – FUEL TOO HIGH" and ejects the "DI" and "F2" automatic electrical fuses (see image c) in the
boiler's electrical cabinet. Conveyors can only be operated if the flap stops pressing at least the micro-switch-2 and if the
enabled automatic electrical fuses "DI" and "F2" in the el. boiler cabinet.
