E. OPTICAL SYSTEM OF ICE LEVEL CONTROL (Two in the models MF
61)
The optical system to control the level of ice (one for each discharge pipe in
model MF 61), installed inside the ice discharge pipe, stop the unit when the
level of ice interrumpt the beam of light(by infrared) transmitted between the
two electronic eyes.
When the beam of light stop, the RED LIGHT in the centre of the electronic
board switch off; the continuos stop of the beam of light during more than 10
seconds stop completly the unit switching on the second YELLOW LIGHT.
The 10 seconds of delay for the stop of the unit prevent that the unit stops by
a chance and undesired interrumption of the beam of light (pieces of ice that
fall for the discharge pipe)
En cuanto se quita el hielo para que el haz de luz pueda volver a pasar entre
los ojos electrónicos, la LUZ ROJA vuelve a encenderse inmediatamente
arrancando, después de 10
F. ELECTRONIC BOARD
The electronic board, located in a plastic box fix in the front part of the unit,
consists of two separate printed circuit, one of high voltage and the other one
of low voltage, protected by three fuses, integrated it by a button RE-SET
(REARM). There are also 5 lights indicating the operation of the unit, one
extra RED LIGHT , 8 DIP SWITCH of switching inlet and some connection
terminals with the inlet peripherals (sensors) and outlet peripherals (electric
components). The electronic board is the brain of the system and process
through the microprocessor, the signals received by the sensors to control
the functioning ot all the electric components of the unit (compresor,
reduction gear, etc).
The five LIGHTS in the front of the electronic board show the following
situations:
12
GREEN LIGHT:
Low tension unit / operation
YELLOW LIGHT:
Unit stop storage full
YELLOW LIGHT:
Unit stop low level of water in the tank
RED LIGHT FLASHING:
3 minutes of delay
RED LIGHT FIX:
Unit stop for high temperature of condensation
Unit stop for room temperature below 3ºC
YELLOW LIGHT FIX:
Unit stop rotation in the opposite direction of
The motor in the reduction gear
Unit stop for speed of rotation of the motor,
Reduction gear too low
YELLOW LIGHT FLASHING
Unit stop for high temperature of evaporation above – 1º C
after 10 minutes of working
