    MDB communication protocol. The models in the ZEN M range use a coin validator. It is always “exact amount”; no change given. On the left of the door there is a space for the coin changer which is held with three screws.
  • Page 15 A12. Coffee grinder The grinder incorporated in Zen machines is Eldom brand, manufactured in Switzerland. Their teeth are conical and operates at low speed, allowing the time-dosed amount of ground coffee, without using a volumetric. Also favor a ground more "soft and gentle" with the coffee, the flat teeth It is supported to a metal support, tied to the frame of the cabinet with 3 screws.
  • Page 16 A13. Button panel and display Zen models, have 8 direct product selections and 4 pre-selections. Activation of these pre- selections and selections are made using capacitive sensors, To order a product you do not need to press any button, just bring your finger to the desired product and the machine providing the service.
  • Page 17 A14. Water inlet EV It allows the entry of water from the mains to the cold water deposit. It works at 230 Vac. This EV is only fitted to machines that are connected to the mains water supply. It has a security block system for cases where, for lime scale or any solids from the main water supply, the EV does not close properly.

    A22. Circuit boards All the models in the Zen range, have 3 circuit boards. The main module is the one that provides the power supply to the other boards and takes the decisions for the correct working of the machine. The other two boards, control independently a determined number of elements in the machine.
  • Page 24 The three boards are joined by one loom of 6 strands called a CAN bus. Two of these wires are used for the transmission of 34 volts, another two for 8 volts and the remaining two are used for the communication between boards. The colour and the function of each of the wires are the following: PIN 1.
