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, beginning with the start of B.
This phase is maintained until the thickness detection sensor gives a signal (which is maintained
during time t2). At this stage, the harvest phase starts.
Please note: during this time the opening of the curtain (MC) has no consequences.
Harvest
Outputs:
- Compressor (C). It is still in operation.
- Hot gas valve (GC). It is active during the whole operation launching time.
- Pump (B) and drain water valve (EP) are active during time t6
- Water inlet valve (EW) is activated when time t6 is over (when the pump is stopped)
The harvest ends when the ice sheet falls down and the curtain micro contact (MC) is activated.
Two possibilities:
1) MC is active during a time less than t3 when the MC signal stops, the production phase will
start.
2) MC is active during a time more than t3 machine will be stopped due to full storage (all
outputs are switched off / LED LE3 continuously switched on). When the curtain (MC) is closed
again, the initial start-up phase will be re-initiated.
