Outputs:
- Compressor (C). It is still in operation.
- Hot gas valve (GC). It is active during the whole operation launching time.
- Pump (B) and wast 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 operation launching 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.
