8.3 Coffee delivery
The corresponding delivery solenoid val-
ves are energised for the time necessary
to distribute the quantity of product pro-
grammed previously (volumetric control)
by pressing the corresponding key: T1-
T2-T3 or T4.
The LED corresponding to the dose key of
the unit selected remains ON all the time
the coffee is delivered while the other Leds
will be OFF.
Interrupting the delivery in progress before
the quantity of product programmed it
reached is possible by pressing any one
of the dose keys on the keyboard of the
unit being used to deliver the product.
Coffee can be distributed simultaneously
from all the units installed on the machi-
ne.
8.4 Continuous coffee dose
Press key T5 on the keyboard correspon-
ding to the unit to be used to obtain con-
tinuous delivery of the coffee dose.
The LED corresponding to key T5 remains
ON all the time the coffee is delivered
while the other Leds will be off.
IMPORTANT!
Avoid pressing the button
for more than 5 seconds, because the
machine will switch to programming mode
in this case
The coffee will continue to be delivered
until the dose is stopped by pressing
key T5, or until the maximum quantity of
product obtainable using the volumetric
control is reached (6,000 impulses) or until
the delivery time-out is reached.

The START mode referred
to the “Continuous” cycle is obtained
when key T5 is released (within 5 se-
conds) and not when this key is pressed.
Whereas, the STOP mode, if applicable,
is obtained by pressing the same key a
second time.
