Programming: Doses; Enabling/Disabling The Buzzer; Excessive Grinder Consumption Alarm; Advice For Users - La San Marco SM 92 INSTANT Original Instructions Manual

5.5 Programming: doses

a. Switch the position of the grinder-dispenser switch 3 from OFF to ON .
b. Within 5 seconds of the LED lighting up on the touch keypad, pressing the key of the dose to program for 5
seconds, single or double dose, the relative key will flash slowly together with the numbers on the display.
c. Release the key and use the adjustment keys (+/-) located next to the display to increase or decrease the
grinding time until reaching the desired value.
d. Once the time is entered, press the key with the flashing led again to store the programmed time.
e. Storing the dose for one coffee makes it possible to program the other dose, independently of the other,
or copy it doubled to the double dose key or, halved, to the single dose key.
f. To store the single dose and at the same time copy it doubled to the double key, simply confirm the pro-
gramming for the single key by instead pressing the double key. To store the double dose and at the same
time copy it halved to the single key, simply confirm the programming for the double key by instead press-
ing the single key.
g. The three digits make it possible to program the time with the precision of a tenth of a second; therefore
two digits for seconds and one for the decimals.
h. If one of the three keys (single, double or continuous dose) is pressed after the operation described in
point a, the "counter mode" is accessed.
i. The display will show the number of coffees distributed from that particular key, in scrolling mode. A dash
on the display separates two subsequent indications when scrolling the numbers.
To reset the counter for a key, simply press the key for which you want to reset the counter for 10 seconds.
To exit the counter mode, simply press the (-) key to the upper left, providing that the mode has not been
exited due to a time out (30 seconds).

5.6 Enabling/disabling the buzzer

As described below, it is possible to program a buzzer that is heard when the keys on the touch keypad are
touched, each time dispensing is complete and when the grinder-dispenser is turned on.
Once accessing programming with the (+) key, press the single dose key for 3 seconds.
A long beep will signal the buzzer off selection, 2 brief beeps signal the activation of the buzzer on mode.

5.7 Excessive grinder consumption alarm

(option can only be enabled using a Pda, a device that is not provided with the grinder-dispenser)
Using a PDA, an operating time can be programmed in hours for the motor. Once the number of operating
hours is reached for the motor, GRN will appear on the display for ten seconds each time dispensing is com-
plete. Storing the number 000, using a PDA, will disenable the alarm.

6. advice for users

• Keep the coffee beans in sealed containers in a dry environment at room temperature.
• Check from time to time the fineness of the ground coffee and the quantities dispensed, bearing in mind
that weather conditions (ambient humidity) have a considerable effect on the preparation of espresso
coffee. Increase the coarseness of the ground coffee when ambient humidity increases and decrease it
when the humidity decreases.
• Have the state of wear of the grinders checked from time to time by authorised technical service person-
nel, bearing in mind that the flat grinding wheels cannot grind more than 300÷600 kg of coffee beans
before becoming useless, while the limit for conical ones is 600÷1200 kg.; remember that both grinders
must be replaced, i.e. both the fixed and the moving grinder, since replacement of one would inevitably
cause malfunctioning of the grinder-dispenser. Replacement must be carried out by authorised technical
service personnel.
• Clean the hopper periodically.
• If the machine is not used for a prolonged period of time (vacation, seasonal work, etc.) completely open
the hopper and clean it carefully.
