Safety Precautions

Safety Precautions

The machine is only intended for water-wash use. Do not allow minors to use the machine.

Do not hose down the machine with water.

The machine's door lock must under no circumstances be bypassed.

If the machine develops a fault, this must be reported to the person in charge as soon as possible. This is important both for your safety and that of others.

The machine is not intended to be used by people (including minors) with reduced physical or mental capacity or lack of experience and knowledge. Such people must be instructed in the use of the machine by a person who has responsibility for their safety. Minors must be supervised to ensure that they do not play with the machine.

All external equipment which is connected to the machine must be CE/EMC-approved and connected using an approved shielded cable.

In order to prevent damage to the electronics (and other parts) that may occur as the result of condensation, the machine should be placed in room temperature for 24 hours before being used for the first time.

The machines feature an electronic programme

unit with fixed washing programmes that may be

changed using optional accessories. The pro-

 

gramme unit also has an in-built self-diagnosis

 

programme, which increases the possibilities for

 

quick troubleshooting.

6569

The motor is frequency-controlled and is controlled by an advanced motor control. This allows precise and flexible control of the motor rpm for any application.

The machines are supplied to customer specifications with e.g. electric or steam heating or no heating, and may be connected to various combinations of cold, warm and hard water.

Function

2This section presents a general overview of the functions of the machine. Most functions are then presented in detailed in separate chapters later on in this service manual.

The machine is freely suspended, which means the outer drum and motor are mounted on a supporting ”cradle” that rests on four shock absorbers for dampening the imbalance in the machine.

The washer drum (inner drum) is belt driven by a motor. This motor is located at the bottom of the machine and is mounted on the cradle with a belt tensioner. The inner drum is mounted to the outer drum at the rear plate with two bearings sealed against leakage with sealing rings.

The drain valve is a water-controlled diaphragm valve alternatively, an electrical drain valve or drain pump.

The door is of sturdy type that is interlocked with a lock module when in operation.

The control panel contains a program knob for selecting the fixed wash programs and a display.

The program unit is mounted inside the control panel. Contactor, water valves, etc., are located at the back of the machine.

Program unit

3The control panel contains a program knob and a display. The panel can also be equipped with two preset buttons.

The control panel and display are used by:

the user to select the machine’s fixed wash programs, to select up to two options for each wash program and for information on the wash process and any fault indicators.

service personnel for navigation and control of the program unit’s service program.

programming personnel for setting and program adjustment in the program unit’s software.

4If present, the preset buttons are used for direct start of two preset wash programs.

Using information on torque values from the motor, the weight of each wash is measured before each wash program in order to adapt the amount of water used for washing.

The program unit controls the water valves, drain valve and heating via an I/O board in the rear electrical module. Control signals to external units, such as detergent pumps or external water valves can also be engaged here.

Motor and motor control

The washer drum (inner drum) is belt driven by a

 

5

 

 

frequency controlled motor. The motor is located

 

 

 

 

 

 

on a motor shelf under the outer drum and has

 

 

 

been arranged with a belt tensioner.

 

 

6

Motor control is microprocessor controlled and

 

 

can control the acceleration of the drum, its rpm

 

 

 

 

 

 

and its retardation very precisely.

 

 

Motor control communicates with the program unit through a serial interface.

The motor control is voltage-fed over a cable which includes two fuses.

The machine’s motor and motor control are described in more detail in the section Motor.

Door lock

7The door lock is electromechanical with twin safety breakers. The lock is bi-stable, i.e. the lock must be given an active signal from the program unit to lock as well as unlock the door.

8A separate circuit integrated in the program unit checks and controls the locking and unlocking of the door through a lock module. The circuit has separate controls that the drum is empty and that it is stationary. Through sensors in the lock module, the circuit checks the door’s closed and locked position. Together with other controls the program unit conducts, this will guarantee the door cannot be opened by mistake.

The machine’s door and door lock are described in more detail in the section Door and door lock.

Heating

9Electric heating heats the washing water with three elements accessible from the front of the machine.

The machine’s heating system is described more thoroughly in the section Heating.

Water connections

9The machine can have one, two, three or four water inlet valves depending on the machine size and customer requirements.

In this unit there are also eight connections for an external detergent feeder.

Rear electric module

10Contains the main switch or terminal block for incoming power, heating contactor, I/O board with outputs for controlling the machine’s water and drain valves and heating. Some machines have an additional I/O board with terminal blocks for connecting e.g. external detergent feeder.

Detergent compartment

11The detergent compartment has four compartments for prewash, main wash, rinse and bleaching agent/liquid detergent.

The machine’s detergent compartment is described more thoroughly in the section Detergent compartment.

Drain valve

11The valve is a diaphragm valve that is opened and closed through water pressure. The control valve is mounted by the water valves.

The machine’s drain valve is described more thoroughly in the section Drain valve.

Frame and suspension

11The machines are freely suspended, i.e. the drum package can move and is suspended in relation to the frame. In this way, a minimum of vibration passes to the bottom plate, which in turn simplifies installation as a concrete foundation is not required.

The machine has four shock absorbers between the bottom plate and the drum package.

The machine’s frame is described more thoroughly in the section Frame.
