MECHANICAL SYSTEM
The mechanical system of the Flaker machines
consists basically of a gear motor assembly
which drives, through a ratched coupling, a
worn shaft or auger placed on its vertical axis
within the freezing cylinder.
The gear motor is made of a single phase elec-
tric motor with a permanent capacitor. This
motor is directly fitted in the gear case through
which it drives - in counter clockwise rotation at
a speed of 9.5 r.p.m. - the freezer auger being
linked to it by the ratched coupling.
NOTE
.
If, after tenminutes fromthe unit start
up, no ice is made and the evaporating
temperature detected by the evaporator
sensor results to be higher than -1°C (30°F)
the ice maker stops (compressor first and
gear motor 3' later) and the
5th WARNING
YELLOW LED
blinks.
The machine will remain in OFF mode for
one hour then it will restart automatically.
In case the unit trips OFF again in alarm for
3 times in 3 hours, themachine SHUTSOFF
DEFINITIVELY.
NOTE
.
In the event the gear motor (one of
the two on MF 66) will tend to rotate in the
wrong direction (counterclockwise) or not
rotating at all or rotating at lower speed the
unit will stop immediately (compressor and
gear motor) with the glowing of the
WAR-
NING YELLOW LED
on account of the inter-
vention of the
Electromagnetic Safety
Device
- based on Hall Effect principle.
The machine will remain in OFF mode for one
hour then it will restart automatically. In case
the unit trips OFF again in alarm for 3 times in
3 hours, the machine SHUTS OFF DEFINITI-
VELY. After having diagnosed and elimina-
ted the source of the gear motor wrong rota-
tion, to restart the unit it is necessary switch
OFF and ON the power line main disconn-
nect switch (Fig. 7). The RED LED will start
blinking and after 3 minutes the ice maker
will resume its total operations by running
first the gear motor and then the compressor.
