PRebReWING
The 3d5 MaEStRo DElUXE dosage function can be configured so that the dispensing relating to the coffee
doses with volumetric control is preceded by prebrewing.
When the dosage function is started, after the time t1(on) the unit solenoid valve EVx is turned off and re-
mains turned off for the amount of time t2(off), except for re-energising to complete the dosage function as
programmed. This timed on/off does not affect the PUMP actuator.
PUMP
When one of the dosage keys with volumetric control, the "normal" dispensing cycle is preceded by a brief
timed water jet used to moisten the coffee pod before moving on to the actual dispensing.
Times t1(on) and t2(off) can be set in TECHNICAL LEVEL programming for all coffee doses. If one
or more details are set to zero, this function is not executed despite being active!
To activate it see TeChNICAL LeVeL Programming.
DISPeNSING COFFee IN CONTINUOUS MODe
In the idle-on status, release one of the doses keys K5GRx (continuous/programming). both the dispensing
solenoid valve EVx and the PUMP are energised, starting up the dispensing phase. The LeD l5GRx relating
to the chosen dose key continues to flash for the entire duration of coffee dispensing.
The display shows
To interrupt dispensing in continuous mode, stop the dosage by pressing the same key K5GRx . This de-
energises the solenoid valve and the pump, and the signal LeD is consequently turned off.
Dispensing in continuous mode stops automatically (if it is not stopped) when the maximum product quantity
is achieved; this quantity can be controlled both in volumetric mode on achievement of 6000 pulses, as well
as by means of a dispensing Time-out (see paragraph entitled ALARMS).
