6.3 Motorized tray
2/6
The movement of the motorized tray is mechanical by means of a stepper motor (1) in 24V DC, controlled by two capacitive pushbuttons (2) located at the front of the tray. The two microswitches (3) are for the limit switch, and operation can be checked in test mode (see section 5.1).

Operating logic with “AQUA PRIMA” filter.
When use of the “aqua prima” filter is selected on the user menu or via the control panel, the system water count logic is as follows:
If the “aqua prima” function is enabled the electronics perform a pulse count of the turbine, recording one pulse every 2 revolutions.
If the “aqua prima” function is disabled, the electronics perform a pulse count of the turbine, recording one pulse every revolution.
The graph in the figure below illustrates this function:

6.5 SBS Valve
4/6
TALEA Section 06
REV00 - August 06
Beverage dispensing
The SBS brewing system valve (see Fig. 2) controllable via the knob, enables variation (increas­ing or decreasing according to the position of the knob) of the water flow rate for brewing. This adjusts the coffee brewing time (extraction time) and consequently the intensity of taste, keeping the cream quality constant.
Function
With the SBS valve in the open position, coffee is accumulated in the membrane valve due to a low back-pressure of the SBS valve. Consequently the membrane valve needle remains in the maximum open position, due to resistance of the spring. Coffee exits quickly (see fig. 3). With the SBS valve in the closed position, coffee is accumulated on the membrane of the valve with a consequent increase in pressure in the valve. The spring yields to the back-pressure and the needle then reduces the coffee passage (see Fig. 4).

SBS valve operation check
To ensure correct operation of the valve SBS a long coffee should be made, and during preparation of the latter, check the difference in dispensing speed between the maximum and minimum positions.
The difference in dispensing speed is approx. 2.5 times greater (and therefore VERY obvious!!).

Brew group valve

Solenoid pilot function:
1. Brew group drain:
before the group is lowered, the solenoid pilot opens briefly creating a depression that in turn opens the valve in the opposite direction from dispensing, allowing any water left in the group to be drained and keeping the pad dry.
2. Coffee ready after steam:
when a coffee or water are selected, the solenoid pilot opens the drain valve to lower pressure in the heater.
3. Prime heater:
after a period in standby or when the appliance has not been used for an extended period (1st coffee), the pump loads briefly during grinding to get rid of any water between the heater pin and heater, and to pre-heat the elements.
4. Fill circuit: the solenoid pi
lot discharges and recharges automatically. The discharge occurs via the drain
pipe and not via the valve.
5. Relief valve: the solenoid pilot also serves as a relief valve (not present on pump), opening in the event
of pressure in excess of 16-19 bars.
6. Lower pressure: pressure is lowered by the circuit being discharged for 10 seconds after water or steam
have been dispensed (see variables A and B).
A) Confi
guration with dual-sensor valve card (water/steam position sensor + Milk Island posi-
tion sensor):
After w
ater has been dispensed - > the solenoid pilot opens to the discharge side as soon as the sensor is disengaged. I
mmediately after steam has been dispensed - > the solenoid pilot opens to the discharge side as soon as the sensor is disengaged. W
ater dispensed after steam has been dispensed -> the solenoid pilot opens to the discharge side as soon
as the sensor is disengaged.
- After each bev
erage has been dispensed -> the solenoid pilot opens to the discharge side.
-
Each time the appliance is switched on and the temperature is reached -> the solenoid pilot opens to the discharge side.
- When the temperature is reached -> the solenoid pilot opens to the discharge side.
B) Confi
guration with three-sensor valve card (water/steam sensor + closed position sensor +
milk island position sensor):
I
n addition to the functions described in configuration A, the following also occur: Each time the closed position centr
al sensor is disengaged -> always open the solenoid pilot towards the
discharge side.
