ACTUATI ON BOARD
This board, placed at the back of the machine, processes the
information from the push-button card and from the payment
system (if fitted); it also controls the actuations, the input signals
and the boiler board.
The 15 VAC voltage necessary for operating the board is supplied
by the transformer, protected by a 125 mAT fuse on the primary
winding and by a 1.25 AT fuse on the secondary winding; the
voltage is rectified and stabilised directly by the board.
This board houses the Flash EPROM. The control software of the
board is installed directly (via RS232) in the microprocessor.
The program can be updated or some of its functions can be
changed through a PC or palmtop with special Software.
- The red LED (7) indicates the operating status of the boiler
heating element;
- The red LED (9) for resetting the CPU glows during the board
reset;
- The green LED (11) blinking indicates that the microprocessor
is working correctly;
- The yellow LED (12) indicates the presence of 12 V DC.

16 – AI R-BREAK AND BOI LERS
The air-break is a functional unit with the function of keeping the water level constant and of signalling a water flow
interruption from the mains; in the event of such water failure it serves the purpose of completing the current selection.
I n the I nstant and FB version the air-break is incorporated in the boiler.
For the KORI NTO I nstant version only the open-top instant boiler is used, fitted with a new design level control
system already used in the KORO model.
For the Fresh brew er model, the same open-top instant boiler used in the I nstant version is adopted.
The open-top boiler for the I nstant / FB version is a new and specific design with the feature of being molded from
thermoplastic material with specific technical characteristics. For further technical information see the functional unit
manuals.

1) Dry operation protection.
2) Anti-boiling protection.
I n the event of failure to the control system and of boiler without water, the thermostat T is triggered at approximately 125 ° C,
disconnecting the power supply. I n order to reactivate everything, the fault must be identified and the thermostat must be
reset by pressing the central red button.
I n the event of failure to the control system and of a full boiler, upon reaching boiling temperature, as the steam exits from
tube A it touches and triggers the two thermostats T2 (each thermostat disconnects one phase of the power supply).
Proceed as above to reset them; see specific chapter to identify the type of malfunction.
See relevant section in the functional unit manual for details, photos and complete description: BOI LERS
The internal temperature control is by means of an NTC type electronic probe fitted with an internal 12K ohm (+ / - 4 ohm)
resistance at a temperature of 25 ° C. The following table shows the changes in internal resistance as the temperature
changes.
We can see that the resistance decreases as the NTC temperature increases
The SW, when reading such changes, causes the activation or deactivation of the heating element with a specific cycle to avoid
temperature changes that are too high.

NOTE 1
The water flow in the mixers is approximately 10 c.c. per second and it is given as a guideline, as there are
many variables that can affect the accuracy.
The liquid dose is determined by the flow-meter pulse counting (volumetric counter).
Both versions (I nstant and Espresso) use an electromechanical vibration pump (with the espresso boiler) for
the water flow, therefore the liquid dose in both versions is measured in flow-meter pulses ( fmp).
NOTE 2
To be noted that the number of pulses does not change in a linear manner (i.e. double the amount of water
does not correspond to double the number of pulses), however the counter varies the accuracy according to
the water flow velocity, and namely:
For espresso coffee it is reduced considerably because of the coffee compress reaction that slows down the
water flow, while it is accelerated in the instant drinks selections, since there are no obstructions to the
water flow. Therefore, in the event of changing the doses set at the factory, some measurements must be
made using measuring containers.

Outline and instructions for use
Note s: Wha t is it a nd wha t is indic a te d by the Europe a n Dire c tive
Directives EEC 93/ 43 and 96/ 3 regard the hygiene of food products and are based on the HACCP
( H azard Analysis Critical Control Point).
The purpose of this directive is to safeguard the consumer health, suggesting a series of actions to be taken
by the vending company, aimed at checking, identifying and correcting any critical aspects in the foodstuff
chain, from the purchase of products and machines to the dispensing of the product.
The HACCP is therefore a system that addresses the analysis of any potential risks in the manufacturing
and distribution cycle of food product and the identification of critical points where such risks can occur; the
system also highlights the actions to be undertaken and the decisions to be made with regard to such critical
points, as well as the implementation of checking and monitoring procedures.
Therefore, each vending company must develop a Company Hygiene Self-control Manual according to the
provisions of the directive - and if necessary use the information and recommendations formulated by some
associations in the sector. The manual must contain a programming and checking schedule for the vending
machine hygiene condition
I mportant notes:
For a correct use of the machine, the directives must be fully applied. The operator is responsible for
correct operations on a vending machine
