1. OPERATING PRINCIPLE 1.1 General operation The machine works according to a pump system developed by Bravilor Bonamat. This system has the following advantages: D The components that are responsible for the correct dosing of the water are housed in a cold water unit. As a result, the largest cause of faults with machines, the formation of scale on the dosing valves, is limited to a minimum. D The float that regulates the water level is also located in the cold−water circuit.
1.2 Water dosing system After a selection key is pressed, the pump motor is driven with a controlled time and speed. The pump rotor displaces a certain amount of cold water from the cold water reservoir to the bottom of the boiler. As a result, the hot water in the boiler is pushed upwards towards the mixing system. Depending on the selected beverage, an ingredient is dosed which, together with the dosed water, is or is not mixed and poured into a cup. ÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁ ÁÁÁÁ ÁÁÁÁ 2.

1.3 Start−up 1.3.1 Initialisation 1.3.3 The machine is switched on with the main switch. On the LCD (Liquid Crystal Display) the following appear in succession: D all symbols that the display can show. D the version number of the software (microprocessor) loaded from the factory. D the version of the software table (Eeprom), also loaded from the factory. This process takes approx. 3 seconds and ends with the steaming cup in the LCD display to show that this phase has successfully finished. 1.3.
1.3.4 Dosing Dosing is allowed when: D The float is in the top position. D After a selection key is pressed, the pump motor (fig.3 ) is driven for a certain time, depending on the programmed amount, with a certain speed (number of revolutions). The volume of the displaced liquid (yield) is mainly determined by the time and speed of the pump motor. The time that the motor is on is regulated from the software and is very accurate.
1.4 Powder dosing system The powder dosing system consists of an ingredient holder (canister) that is driven by a motor (canister motor). After the start key is pressed, the canister motor will rotate after a certain delay. This motor drives a worm, which transports the ingredient to the canister outlet. The control of the canister motor makes it possible to regulate timing and dosing speed independently. As a result, the ingredient can be poured into the mixer at the same time that the water flows out.
1.5 Mixing system 1.6 The mixing unit (fig.7 ) mixes the hot water and the ingredient. After a selection key is pressed, the water will be dosed in the mixing chamber after a certain delay. The product falls into the mixing chamber from above. Depending on the selected beverage, the mixer will start to rotate with a certain number of revolutions. An exhaust opening is mounted on top of the mixing chamber (fig.6 ).
1.7 Operating system The operating system consists of a: D Keyboard D Main board 1.7.1 Keyboard 1.7.2 The keyboard is located on the front of the machine and contains various keys and the display. This board contains inputs and outputs of the machine and the microprocessor with memory. Saved settings such as the dosing quantities, counters, etc. are stored here. When this circuit board is replaced, the customer−specific settings will be lost.
1.8 Hardware protections The machine is equipped with a number of hardware protections. These protections ensure that no dangerous situations can arise, such as overheating and/or water in the machine. 1.8.1 Back−flow protection The water from the magnetic valve is sprayed against the cover through a pipe in the cold water tank. Then it flows into the cold water tank.
1.9 Software protection The machine has been equipped with a number of software protections; the software monitors all inputs and outputs of the machine throughout the process. If non−allowed situations arise, the software will intervene. This intervention results in the machine being switched off and an error message being shown on the display. Fig.
1.10 Programming The programming is built up by means of a simple programming carrousel. Have the user instructions open next to this text. After the programming is activated by means of the programming key, settings can be simply activated or changed. By pressing the programming key again, the settings are saved the machine returns to the standby mode. 1. Open the door with the key. 3.
