Tilt switch and electronical repetition system
Tilt switch
The tilt switch is mounted on the solid part of the machine. There is a window
around the probe of the tilt switch that is mounted on the movable part of the
machine.
When the machine goes out of balance by overloading or uneven distribution of
the linen, the tilt switch will interrupt this action to prevent damage to the machine.

window
Important
To guarantee good functioning, the probe should be centered horizontally
and vertically at 1/3 from the bottom of the tilt window (when machine drum
is empty).
Electronical
repetition system
The spin is controlled by the electronical repetition system. This system is
responsible for the drive of the different motors during high and low spin.
Operation:
The printboard will be activated during the drain, and the following actions occur:
a) The micromotor of the programmer stops.
b) The distribution speed is activated and the drain valve opened.
c) After the water is drained completely, the machine starts low spin at 500 rpm.
d) After 240" low spin, high spin starts at 1000 rpm.
The duration of the high spin (1000rpm) is determined by the programmer.
In case the machine is out of balance during spinning, the spin motor will stop while
the linen is redistributed via the wash action. After 30 sec. the machine will try again
to spin.
Every time the machine is out of balance the spin time
shortens by 30 sec
. (Not with
PLC-9).
When the drain valve is obstructed, the same things happen as when the machine
is out of balance.
After a power failure during spinning, the machine starts at point a) (see operation).
After an interruption by the thermo-magnetic motor protection during spinning,
the machine starts at point a) of the described operation.
Machines with electronical microprocessor PLC-9 have the repetition system
printboard integrated on the main printboard.
In this case the repetition process
will be executed no more than 15 times without shortening the spin time.
