SECTION 6 OPERATING LOGIC REV.
6.1 Reset coffee grounds drawer. The “empty coffee grounds drawer” message is signalled by a “coffee” beverages counter controlled by the appliance electronics. The counter is cleared “empty coffee grounds drawer” reset message: 1. After 13 coffees, if the grounds drawer is removed for more than 5 seconds. 2. Each time the grounds drawer is removed for more than 5 seconds when an “empty coffee grounds drawer” alarm has been generated (it is assumed that the grounds drawer has been emptied). N.
6.3 Motorized tank The movement of the motorized tank is mechanical by means of a stepper motor (1) in 24V DC, controlled by two capacitive pushbuttons (2) located at the front of the tank. The two microswitches (3) are for the limit switch, and operation can be checked in test mode (see section 5.1).
6.4 Aqua Prima 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.
6.5 SBS Valve 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.
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!!).
6.6 Solenoid pilot Needle Drain Brew group valve (3 - 5 bars) Brew group drain 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.
6.7 Milk Island Electrical connection to appliance. Button to attach/release Milk Island from appliance. Water pipe connected to appliance for steam inlet. Steam outfeed Anchor pin between Milk Island and appliance. Carafe present LED Unscrew bolts indicated to dissassemble. 1 5 2 1 Cappucinatore cover. 3 2 Cappucinatore valve cover. 4 3 Vernay valve. 4 6 7 Cappucinatore valve cover insert. 5 Cappucinatore body. 6 Carafe handle. 8 7 Carafe milk suction pipe. 8 Carafe steamout pipe.
