  • Page 16 A14. Selection panel In the Zensia models, the product selection buttons are touch sensitive; to select a product it is not necessary to press a button, just put one’s finger near the product required and the machine detects its presence, which activates the service of the product requested.
  • Page 17 A15. Water inlet Electro-valve This allows water from the mains to enter the cold water deposit. It works on 230 Vac. It has a security mechanism for cases where solids, such as scale or any other solids, or the EV does not close properly and does not cut the entry of water into the machine.
  • Page 18 A16. Volume meter This meter measures the quantity of water that the pump sends for the elaboration of coffee espresso. Inside there is a flow meter with two small electro-magnets that spin with the flow of water. As it spins, 5 Vdc electrical pulses are sent to the infusion board.
  • Page 19 K1. By-pass K2. Anti-return valve When the product to be elaborated is an instant product, there is no resistance for the water to go from the boiler to the beater, so that when instant products are elaborated, the pump operates at a lower pressure than when an espresso coffee is elaborated. The pump has an anti-return valve that prevents the water returning to the boiler.
  • Page 20 A19. Hot water boiler for espresso machines The boiler works under pressure. Its capacity is 320cc of water. It heats the water for both products, espresso coffee and instant products. L1. Temperature sensor (PTC) L2. Security thermostat: switches off at 120º C L3.
  • Page 21 N1. 3 way closed N2. To infusion group N3. Entry of water from the boiler When the machine finishes elaborating an espresso coffee, the 3-way EV goes to rest position, so that the water outlet from the boiler and the group are connected to the third outlet. This way, the water that didn’t pass through the coffee, and that is retained in the group, is taken through the third channel to the residue bucket.
  • Page 22 Q1. White Q2. Black Q3. Brown The control of the temperature of the water in the boiler is with a PTC100. The following table shows the values that the PT100 shows for the temperature it detects. The boiler works under pressure and has capacity of 350cc of water. The water for the elaboration of the products is heated here, for espresso coffee and for instant products.

  • Page 24 A20. Hot water boiler for instant machines The hot water boiler for machines that only have instant products works at atmospheric pressure. The hot water goes to the beaters due to gravity. It is therefore not necessary to have a pump or a deposit for the cold water, unlike the machines for espresso coffee. This machine measures the quantity of water necessary for elaborating the products by the time the EV is open, so it does not have a water meter either.
  • Page 25 A23. Electronic boards All the models in the Zensia range have 4 electronic boards. The PMC module (Payment methods Communication), provides the power supply voltage to the other boards and makes the decisions for the machine to work correctly. The other three control independently a number of other devices in the machine.
  • Page 26 S1. PMC Module S2. IDU Module S3. Infusion Module S4. Cup Module The four boards are linked by one unique 6-way cable called a CAN bus. Two if these lines are used to provide a voltage of 34 volts, another two are for the 8 volt supply and the remaining two are used for communication between the boards.
  • Page 27 A25. Scale filter The espresso models have a scale filter fitted, Purity C150 Quell ST from Brita. The head piece is fixed the cabinet, in the lower part of the machine, whereas the filter is supplied in a box; it is easy to fit, just follow the instructions on the filter.
  • Page 28 INSTALLATION AND START UP 3.1. UNPACKING Only unpack the machine at the moment of installation in the site where it will be used. Dispose of the packaging following the current legal norms for these materials. Safety Norms: Do not touch any mechanisms when you have wet hands or feet. Do not plug in the machine with bare feet.
  • Page 29 3.2.2 Electrical Connexion The machine requires a voltage of 230 Vac (50 Hz). The installation point must have:  A “Euro” approved socket with an earth connection.  A minimum power rating of 2,500 w.  The electrical installation where the machine is sited will be protected with a cut off fuse and have an earth connection.
  • Page 30 3.2.5 Filling the hot water boiler On connecting the machine, the hot water boiler fills automatically. In the espresso coffee machines the following processes take place: The cold water fills the boiler if it is empty. It checks the water meter is working and it fills the boiler with the EV closed, it detects it is full when the water meter stops spinning.
