keypad also provides management of the "DOSE LEVEL" LEDs on the
keypad (L7GRX - L12GRX). Once the dose underway is stopped as
described in the previous paragraph, these will remain in the same
"dose level" state as before the STOP distribution for a period of
about 10", after which they will switch OFF.
PRE-BREWING
The 3d5 MAESTRO DELUXE doser may be configured in such a way that the
distribution of coffee doses with volumetric control is preceded by pre-brewing.
When dosing starts, the group solenoid valve EVx switches off after the time t1(on)
and remains off for the time t2(off); it is then re-energised to complete the dose as
programmed. This timed on/off does not involve the PUMP actuator.
When one of the dose buttons with volumetric control is pressed, the "normal" di-
stribution cycle is precede by a short timed jet of water used to moisten the coffee
capsule before moving on to the actual distribution.
ATTENTION: the times t1(on) and t2(off) can be set in the TECHNICAL LEVEL
Programming for all coffee doses. If a zero value is assigned to one or more quantities, this function, though active, is not performed!
To enable, see TECHNICAL LEVEL Programming.
COFFEE DISTRIBUTION IN CONTINUOUS
MODE
From idle-on status, pressing one of the dose buttons K5GRx (continuous/
programming), both the distribution solenoid valve EVx and the PUMP are
activated, starting the distribution phase. The LED L5GRx for the button of the
chosen dose remains lit during the whole distribution of coffee.
the display shows:
To interrupt distribution in continuous mode, STOP the dose by pressing any dose but-
ton on the keyboard used for distributing the product. This de-energizes the solenoid
valve and pump, and consequently the warning led switches off.
Distribution in continuous mode is stopped automatically (if no stop command is
given) when the maximum product quantity is reached; this quantity may be controlled
both volumetrically when 6000 impulses are reached and by means of a distribution
time-out (see ALARMS paragraph).
IMPORTANT: THE "CONTINUOUS" CYCLE IS STARTED WHEN THE BUTTON K5GRx
IS RELEASED (WITHIN 5 SECONDS, OTHERWISE THE PROGRAMMING PHASE
BEGINS) AND NOT WHEN IT IS PRESSED. INSTEAD THE STOP DOSE OCCURS
WHEN THE BUTTON IS PRESSED.
TEA CYCLE
DISTRIBUTION
When the button for the Tea dose (K6GRx) is pressed the tea solenoid valve (EVTEA)
is activated, starting the distribution of hot water. The operation is indicated by the
lighting of the LED (L6GRx) corresponding to the button pressed.
At the time of starting the cycle a Timer is activated which stops product distribution
once the time value set during programming is reached.
The doser allows simultaneous distribution of both the tea and the coffee cycles.
the display shows:
Stop tea distribution in progress
It is possible to interrupt the distribution in progress before reaching the programmed
time by pressing the same button used to start the distribution of the dose of tea.
This operation immediately de-energizes the solenoid valve EVTEA , interrupting the
