1. Clean the filters with water and steam inlets by chapter 5.10.
2. Remove the rear machine cover and check the condition and tightness of the V-belts (chapter 5.9.).
WARNING!
BEFORE REMOVING TOP OR BACK PANEL OF THE MACHINE, SWITCH POWER OFF AND WAIT
FOR AT LEAST 10 MINUTES. BEFORE STARTING INSPECTION OF FREQUENCY INVERTER,
CHECK FOR RESIDUAL VOLTAGE ACROSS MAIN CIRCUIT TERMINALS + AND -. THIS VOLTAGE
MUST BE BELOW 30VDC BEFORE YOU CAN ACCESS THE INVERTER FOR INSPECTION.
3. Clean and remove dirt and dust from:
– the cooling fin of the inverter
– the motor cooling fins
– the internal ventilator of the inverter (if present)
– the external ventilator (if present)
– the external air relieves of the machine
– check if ventilator in coolfins of inverter (if present) is functional
– check if external ventilator (if present) is functional
5.6. SAFETY VIBRATION SWITCH
FUNCTION DESCRIPTION
The vibration switch is an important safety element which must - if correctly adjusted - stop the machine
if excessive vibrations and shaking occur due to an unbalance caused by improper distribution of linen
in the washing drum. Because this component is very important, it is recommended that at the first installation
and then once in a year the vibration switch was verified by a qualified worker.
MACHINES 33-40-55 kg / 80-100-125 lb, FIGURE 5.6.A
The unit contains the vibration switch (figure 5.6.A., pos.5) with a flexible controlling element which is attached
to a holder (7) by nuts (6) and this entire assembly is bolted to the bottom of the switchboard (4). The switch
controlling element is inserted into the rubber bushing (3) located into the limiter (2) which is bolted to the drum
front face (1). The switch attached to the switchboard is a part of the machine skeleton which is attached
to the frame and the limiter with the bushing is a part of the assembly that vibrates. The vibration switch
sensibility is given by a mutual adjusting of these two components which controls the unbalance level of linen
in the drum.
MACHINES 80-100-120 kg / 180-230-275 lb, FIGURE 5.6.B
The unit contains the vibration switch (figure 5.6.B., pos.4) with a flexible controlling element, which is attached
to a holder (6) by nuts (5) and this entire assembly is bolted to the rigid machine frame (3). The switch controlling
element is inserted into the limiters (2) which is bolted to the front part of moving frame(1). The limiters
are a part of the assembly that vibrates. The vibration switch sensibility is given by a mutual adjusting of these
two components which controls the unbalance level of linen in the drum.
SENSIBILITY ADJUSTMENT, MACHINES 33-40-55 kg / 80-100-125 lb, FIGURE 5.6.A
1. By moving the limiter (2) up or down (direction A), you will adjust the centre of rubber bushing to the control
element axis of vibration switch.
2. By moving the vibration switch on the holder (7) to the left, you will increase the sensibility and to the right
you decrease it (direction B). To reach the maximal permitted unbalance value it is necessary to keep the
distance of 100 mm / 3.93“ between the limiter (2) and the vibration switch (5) - see the side view.
3. Moving the holder (7) with the switch left or right (direction C) you will centre the switch control element
in the rubber bushing of the limiter.
