The systems adopted are outlined below, while the general operation of the machine is as described for the automatic models.

The counts for coffee or tea servings are also shown on the computer; in the HARTEK, WALLA and RS-232 models they can
also be printed.
The counts are shown in totals per type of serving; e.g., strong, normal and weak coffee and manual.
Decaffeinated coffees are served only in single strong, normal and weak portions; teas are served in normal, weak or manual
servings (the servings with double cup are counted as two; manual servings are counted as one). The total number of cycles
served is also available (total coffee and tea).
The RS-232 and MEMOBOX 2 systems can control the work performed by a number of persons; in other words, by means of
the WAITER’S KEYS it is possible to memorize and display the number of coffees and teas served by each waiter.
With MEMOBOX 2, if the Exclude Grinder function is switched ON (“1” on the display), the serving of coffee and the
quantity will be determined by the impulses from the grinder-metering unit.
When the grinder-metering unit sends an impulse to the electronic control unit, it enables the serving of a single coffee; when it
sends two impulses it enables the serving of two coffees. If no coffee is drawn from the grinder-metering unit and the “Manual
Serving” button is pressed, the relative led lights up. This function makes it possible to use the decaffeinated coffee and to have
the relative separate counting.
