1.2. Water characteristics

The appliance must be supplied with drinking water having the characteristics shown in the table. If these characteristics are not complied with, the appliance might suffer damage; a water treatment device should therefore be installed.

2. FUNCTIONAL DIAGRAM COMBI OVEN

11 12

The system works in two distinct ways depending on whether the motorised valve is opened or closed.

2.1. Open valve operation

The rotation of the fan creates a vacuum effect in the local area behind his disk back where it faces the suction pipe/exhaust 5. When the butterfly valve 7 is open to this effect a vacuum sucking air flow entering through the pipe 5. Simultaneously the moist air inside the cooking chamber is induced to leave through the vent tube 6, aided by a flow diverter (not shown) placed inside the chamber at the exit hole. Through the injector 12 is sprayed water into the vent pipe - especially at high temperatures - in order to cool and condense the flow of moist air coming out. The condensate is collected on the bottom of the pipe to siphon 6 and conveyed through the rubber hose 14.

2.2. Closed valve operation

With the valve closed, the steam can not escape from the vent pipe 6, or from the tube 5 at least until the pressure inside the cooking chamber is not sufficient to overcome the effect of decompression generated by the rotation of the fan (usually 1,5-2,0 mBar). But when the pressure chamber exceeds the decompression generated by the fan, the steam excess is expelled through the tube 5. The system operates as a closed system, where the overpressure valve (overpressure valve in the FM ovens) is dynamically replaced by the effect of decompression generated by the fan. Even in this mode, water is sprayed by the injector 12 in order to maintain the siphon full. Note that, unlike than the FM, the condensate tube 14 is connected upstream of the swing of the siphon, as with the motorised valve closed the vent pipe 6 and the drain tube 14 are at the same pressure of the cooking chamber.

The two modes of operation described above are used in different modes of cooking in the following way:

Convection cooking: means the user can determine the % the vent valve is open according to the diagram below.

0% - vent completely open (bar on the display all red)

from 10 to 90% - the valve opens and closes in timed mode, the value shown on the

display is the % of time that remains closed.

100% - vent completely closed (bar on the display all grey)

Combi cooking mode: the user can set the desired % of steam - the opening and closing of the vent valve is controlled automatically by the oven, based on values detected from the apposite humidity probe.

Steam cooking: valve remains closed.

2.3. Drain cooldown / steam condensing operation

The inlet water assembly 11 feeds the cooling water injector 12. The opening of the water solenoid valve is timed based on the mode of operation (convection, combi or steam), chamber temperature and the temperature detected by temperature sensor 9.

The inlet water assembly 11 is different depending on the levels:

Level 3

It consists of:

- Back flow preventer (non return valve) EN1717 (for washing)

- Pressure reducer (for washing)

- Double water solenoid valve (one is for washing)

- Pressure switch on the drain cooldown line

- Pressure switch and manometer on the washing water line

Note: the water pressure adjustment should be done during a washing cycle.

Level 2

It consists of:

- Double water solenoid valve (one is for cleaning)

- Pressure switch on the drain cooldown line

- Pressure switch on the washing water line

- Pressure reducer (only models FX201-202)

The power board (2) receives all the signals from the oven probes (PT1000 temperature sensors, door micro switch, core food probe, etc.) and controls all organs of the oven through the appropriate relays. It communicates with the CPU board (1a), with the inverter (4) and the combustion and fan control boards (3) (only for gas) via RJ45 network cables.

If there is no communication between the power board (2) and the CPU board (1a) or the board or the inverter or the combustion control board a warning alarm appears E13 (communication error alarms, see table).

The management programme of the oven consists of three parts:

Firmware (FW) – it controls the operation of the oven (inputs and outputs) – it is in the power board (2)

Software (SW) - Contains all the user interface, programs, pictures, etc.. – it is in the CPU

Operating System (OS) – it is in the CPU

Versions of OS, SW and FW are shown in the upper part of the Service menu.

should no longer appear.

3.4. Inverter

The inverter keyboard is disabled as the operating parameters are sent to the inverter via power board. This component allows us to select up to five motor speeds and the static way of cooking, with fan stops (when the heating element is inactive).

The inverter is equipped with a heat dissipater and a cooling fan situated at the bottom of the item. The inverter inner temperature is monitored by an internal temperature sensor, if the temperature exceeds 50° C, the inverter blocks (show the alarm E06: 8 see alarms table). The over temperature alarm may be due to rupture of the cooling fan, in which case you can replace the single cooling fan.

Once you remove the power supply on the oven, you have to wait 3 minutes before starting maintenance on the inverter or the motor due to electrical hazards.
