DESCRIPTION OF COMPONENTS

A. TEMPERATURE SENSOR OF THE EVAPORATOR
The sensor of temperature of the evaporator, located inside a bulb pipe, it is
welded in the outlet of the freezer tube, register the temperature of the
refrigerant aspirated transmitting a signal (low tension electricity) to the
microprocessor.
Depending on the signal received, the microprocessor give green light to the
ice equipment to continue working (evaporation temperature below -1°C after
10 minutes working or in case there is a lack partially or totally of refrigerant in
the system, stops the equipment flashing the 5a YELLOW LIGHT
(evaporation temperature above -1°C after 10 minutes of operation).
B. SENSOR OF WATER LEVEL FLOAT TANK
The sensor of water level of the flowt tank it is composed of two stainless
steel sensors vertically anchored to the lid and connected electrically to the
low tension circuitry of the electronic board.
Its lower extreme is sumerged in the water tank and throught a current of flow
that it is transmitted through the mineral salt of the water, mark its presence to
the electronic board.
NOTE. The lack of water or the presence of water whitout mineral salt
(electrical conductivity below 30 mS)means the interruption or reduction of
the electric current transmitted to the electronic board, with the consequent
stop of the unit, show with the switch on of the YELLOW LIGHT.
C. SENSOR OF TEMPERATURE OF THE CONDENSER
The sensor of temperature of the condenser (located between the wings of
the air condenser or in contact with its coil in the case of water condenser)
registers the temperature of condensation and transmitt the variations
sending a signal to the electronic board.
In case the temperature of sensor of the condenser have a value below +3°C
(room temperature too low), the electronic board don't start up the unit the
temperature of the probe gets to +10°C.
In the models cooled by air, the probe of the condenser control also the
operation of the fan motor through a MICROPROCESSOR of the electronic
board. Using the TRIAC, tjos start up the motor of the fan removing the heat
of the condenser and consequently lowing the temperature.
If the temperature of the condenser is above 62°C to 70°C depending on the
position of the microswitch number 8, the signal that arrives to the
MICROPROCESSOR make to stop the unit.
NOTE. So as the unit start up again, push the button REARM (after solving
the cause that has produce the stop) or unplug and plug again the unit.
D. SPEED SENSOR AND DIRECTION OF MOTOR IN THE REDUCTION
GEAR (Two in models MF 61)
The sensor of speed and the direction of rotation of the motor in the reduction
gear (one for each motor in model MF 61). Register through a magnetic
signal (effect hall) the speed and direction of rotation of the motor. When it is
below 1300 revolutions by minute, the signal transmitted to the
MICROPROCESSOR of the electronic board stop inmediately the unit and it
switch on a YELLOW LIGHT.
The same happens when the motor run in the incorrect direction avoinding
that the ice inside the evaportor make a unic body with the axis.
NOTE. To start up the unit in both cases ( slow don and attempt opposing
rotation) push button rearm (after solving the cause that has produced the
stop) or the switch and the electrical connexion.
