Via terminal 2 on micro G2, current reaches the pump. Circuit 4 on micro G2 which provides
current to the hot gas valve (Q) and water inlet valve (P) will be interrupted. Since the
thermostat
is between 1 and 3 the timer will receive no current. The compressor continues
switched on.
-
Air-cooled machines have a fan (R) which is controlled by the pressostat (F).
-
In water-cooled models without pressostatic valve, pressostat (J) opens and closes the
condenser electrovalve (K).
-
Evaporator temperature decreases until the cycle thermostat (T2) set point is reached, at this
temperature circuit 1-2 will be closed and timer motor (G) will switch on.
-
Once the cycle is over, the pins on the timer wheels will force the micros to change circuits,
stopping the pump and opening the hot gas valve and water valve. The combined effect of hot
gas and water sprayed on the top of the evaporator will release the ice cubes and change the
position of the cycle thermostat (T2).
-
The ice production and defrosting cycle will continue until the ice storage bin is full, at which
point cycle thermostat (T1) will disconnect the machine, but never during a cycle, but at the
beginning of the defrosting stage, since during the production cycle, current will reach the pump
via terminals 1-2 of micro G1.
-
The machine will remain disconnected until the level of ice in the bin drops below the
thermostat because of ice consumption. At this point the bin thermostat T1 changes and the
machine will start a new production cycle automatically.
