Timing The following time chart indicates the functions of the individual components in terms to time HS - ON Timing Grinder motor Heating app.45sec Pump Gearmotor Status MS1 Status MS2 Heating stage Status Explanation: Two processes start when the main switch is activated: Firstly, the gearmotor is initialised.
  • Page 44 4. FUNCTION/TIMING 4. Function 4.1. Gearmotor The gearmotor is connected to the power element of the circuit board via the auxiliary heating system. In order to perform forwards and backwards movements, the gearmotor is controlled alternately with a positive and negative half wave. The voltage is limited by the electronic system to approx. 30 to 35 V. The electronic system of the motor is switched off in the event of an overload.
  • Page 45 INCANTO S-CLASS 4. FUNCTION/TIMING 4.4. Flow meter (Turbine) The machine is equipped with a flow rate monitoring system. The system checks whether the turbine (flow meter) rotation speed at a particular time complies with the pre-set value. If no pulses are generated from the turbine within 10 seconds, the current cycle is interrupted.

Grinder The grinder is fitted with grinding discs. The grinding discs are made of ceramics. ATTENTION: Adjust the grinding level only when the grinder is in operation! EXCEPTION: Grinder is empty.
  • Page 47 INCANTO S-CLASS 4.9. SBS Saeco Brewing System 4.9.1. General functioning The water flow speed through the brewing unit can be slowed or accelerated by means of an adjustable flow valve (Fig. 2) which is activated by turning the knob on the front of the coffee machine. The contact time of the water with the coffee in the brewing unit (extraction time), and consequently, the coffee concentration, is changed accordingly, while maintaining consistent froth formation.
  • Page 48 4. FUNCTION/TIMING INCANTO S-CLASS 4.9.2. Froth valve functioning The backpressure in the froth valve and, consequently, on the membrane of the froth valve, is minimal when the flow valve is open. Accordingly, the valve needle is kept by the spring pressure in almost home position and the flow is at maximum (Fig.
  • Page 49 INCANTO S-CLASS 4. FUNCTION/TIMING 4.9.3. Extraction values with SBS A comparison of the measured values (dosing quantity 9g/SBS min.; dosing quantity 9g/SBS max. and dosing quantity 6g/SBS min.) indicates that the change from SBS min. to SBS max. corresponds with a change in dosing quantity of 1.5g.

  • Page 152 4. FUNcTION/TIMING 4. Function 4.1. Gearmotor The gearmotor is connected to the power element of the circuit board via the auxiliary heating system. In order to perform forward and backward movements, the gearmotor is controlled alternately with a positive and negative half wave. The voltage is limited by the electronic system to approx. 30 to 35 V. In the event of overload the motor's electronic system switches off after 8-10 sec.
  • Page 153 INCANTO 4. FUNCTION/TIMING 4.4. Flow meter (Turbine) The machine is equipped with a flow rate monitoring system. The system checks whether the turbine (flow meter) rotation speed at a particular time complies with the pre-set value. If no pulses are generated from the turbine within 10 seconds, the current cycle is interrupted.

Grinder The grinder is a conical grinder with upper and lower grinding disc. The grinding level is set by adjusting the height of the upper grinding disc by means of the screw thread.
  • Page 155 INCANTO 4.9. SBS Saeco Brewing System 4.9.1. General functioning The water flow speed through the brewing unit can be slowed or accelerated by means of an adjustable flow valve (Fig. 2) which is activated by turning the knob on the front of the coffee machine. The contact time of the water with the coffee in the brewing unit (extraction time), and consequently, the coffee concentration, is changed accordingly, while maintaining consistent froth formation.
  • Page 156 4. FUNcTION/TIMING INCANTO 4.9.2. Froth valve functioning The backpressure in the froth valve and, consequently, on the membrane of the froth valve, is minimal when the flow valve is open. Accordingly, the valve needle is kept by the spring pressure in almost home position and the flow is at maximum (Fig.
  • Page 157 INCANTO 4. FUNCTION/TIMING 4.9.3. Extraction values with SBS A comparison of the measured values (dosing quantity 9g/SBS min.; dosing quantity 9g/SBS max. and dosing quantity 6g/SBS min.) indicates that the change from SBS min. to SBS max. corresponds with a change in dosing quantity of 1.5g.
