4.4 INNOVATIVE FEATURES

Once a programme has been set, the first thing that the LVS will proceed to do is discharge the water. Following this, it will start to

fill up with water in two stages:

1. Static Filling up: the Main-board will order the electro-valve to open which will allow from 2.5 to 3 litres of water to flow

in(depending on the machine)which in turn is controlled by the Turbine Litre-count. On having achieved the prescribed lelvel, the

Main-board will proceed to check whether the " full pressostat status" has been achieved.

Under normal working conditions, should "full Pressostat"status be achieved, then it will proceed to fill up dynamically; if not, it will

proceed to fill up more water: approximately 100cc more. Another possibility would be either the "full Pressostat" has been

achieved, and if so, it will proceed to fill up dynamically, if not, it could go in alarm and indicate the reading "Pressostat not

Compliant".

2. Dynamic filling up: Once the "full Pressostat" has been ensured, then the Main-board will start the motor working and will

open the electro-valve thus permitting to fill up up to 4 litres of water.

Should the Main-board, following the second filling-up stage detect "Full Presostat" then the dishwasher will proceed to wash;

otherwise, it will continue filling up water till it has achieved "full Pressostat" or up to 5.5 litres of water-capacity (depending on

which of the circumstances take place first.). Either it will proceed to wash normally having achieved the status of "full" or it will

proceed to discharge the water in the following phase.

NB:

The manual filling up of water in the dishwasher basins has not been envisaged on Models EOS, but only "Alarm

Turbine". The Turbine Litre-count and the Pressostat, donot work together, hence the results given by either one of

them, must be confirmed by the other. If water is fill ed up manually, the Pressostat will detect the status of "full"and the

Turbine will indicate that the water has not been filled up because the latter has not detected the water flowing into the

dishwasher, thus provoking a sort of conflicting circumstance that will make the dishwasher go in alarm.

The salt-quantity is administered via a visual sensor represented by Led that emits and one that receives. It is important to note

that the sensors have not been placed at the bottom of the sweetener, but halfway. This has been done in order to prevent the

presence of impurities in the salt to give a false reading.

Any presence of salt, will interrupt the beam of light, suggesting to the Main-board that there's salt in the sweetener. When the salt

goes below the level prescribed by the sensor, the Main-board will receive the message that sthere is no salt. As the sensor is not

placed at the bottom of the sweetener, other regenerating processes can be made, and the main-board will switch the Led on

after six regenerating stages starting from the moment it received the indication that the holder was empty.

N.B:

When the LED is on, the dishwasher will not proceed to "regenerate". Should the salt-connection not be plugged in, the

Main-board will receive the message that the salt-holder is full, hence the LED will not go on. If the technician had to

plug in the connection, the LED will not go on immediately. The Main-board will detect this status, and hence will start

calculating from six long "regenerating" cycles, and only following this will the Led go on.

If the salt-Led is on, the dishwasher will not proceed to "regenerate" even though the figures indicating the quantity

exceeds the limits prescribed by Editor.
