Element 44 detects the presence of electrical power in the machine.

If the circuit is closed by switch 43, A switching coil 47 closes the switches 48, 49 and 50 and sets a motor 61 in motion and at the same time closes a switch 52 by means of the switching coil 51, so that now Current can flow to the contacts 53, which feed a group of solenoid valves 54 and this partial circuit conclude.

Y. ^r hen the other hand, a switch 55 is closed, flows in the case of the presence of a cup, the presence of which is determined by an element 57 flow through an element 56 to a solenoid valve 58 and the switch 52 is turned off by the switching coil 51st

The water flowing out of the opened solenoid valve 58 is dosed by the previously mentioned element 56 and the circuit closes in its entirety and the Operation is finished. When the switch 55 is closed, electric current flows through the elements 45 and 45 ' the preparation of the later falling of the money to finish of the operation, an element 63 preventing a possible new flow of current. Contact 53 acts when dispensing the amount of coffee on the element 45 ', the the entire circuit opens.

As already said, the element 57 represents the presence of a cup and in the negative case the element gets 59 current, which in turn is the group of elements 46, 45 and 44 actuated, which carry out the Ztirüokgabe of the coin.
