remove mineral deposits. After this (water pump and drain electro valve de-energized) the water
inlet valve is energized filling the water tray until the water level sensor detects water reaches
the level. The ice slab slides off the evaporator and into the bin. The momentary opening and
re-closing of the shield indicates the harvest sequence has finished and goes to the freeze
sequence.
5.1. Initial Start-up
It is carried out at machine work start in following cases (being all outputs switched off):
- when machine is connected to power supply.
- when the switch is turned to the ICE position
- after a stop due to full storage
During start-up time t4 the pump (B) and the drain valve (EP) are activated.
Subsequently, B and EP are closed and the water inlet valve (EW) is opened until the level
sensor (NW) indicates that the storage reservoir is filled with water. At this point, the hot gas
valve opens for a time t20, and then the production phase starts. LE1 on
Please note:
If at this stage the curtain (MC) is open, the indicated machine status is switched
to full storage (full).
Production
Following outputs are activated:
- Compressor (C).
- Pump (B). It is activated with delay time t11.
- Water inlet valve (EW). It is kept active during time t8, if the water level (NW) is not
reached the water valve (EW) will keep open (even after the time t8) until the water level probe
(NW) detects water tray full.
This phase is maintained until the thickness detection sensor gives a signal (which is
maintained during time t2). At this stage, the operation launching phase starts.
*LE1 on
Please note:
during this time the opening of the curtain (MC) has no consequences.
