A Warning and Safety Instructions

1 General information

Service and repair work should only be carried out by suitably qualified persons in accordance with all appropriate local and national safety regulations.

Servicing, modification, testing and maintenance of electrical appliances should only be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

All regulations of the appropriate utility supply companies and standards relating to safety (not limited to electrical safety) are to be complied with.

Before any service work is commenced, the machine must be disconnected from the mains.

Even with the machine switched off, mains power may be applied to some components.

A general visual check should always be carried out.

A-2 DTD no. 521-7135

2 Risk of injury due to sharp edges

There may be a risk of injury due to sharp edges.

Protective gloves should be worn and the edge protection, Mat. no. 05057680, should be used.

Page 9

Descriptive Technical Documentation

DTD no. 521-7135 A-3

3 Electrical connection via plug connector

It is always recommended to make electrical connection via a plug and socket so that electrical safety checks, e.g. during repair or service work, can be carried out easily.

The socket must be accessible after machine installation. This also applies even if an on-site mains switch is also already provided.

For models with a total connected load greater than 9 kW, an additional on-site mains switch must also be provided.

Electrical connection must be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

A-4 DTD no. 521-7135

4 Touch current measurement

Note

On machines with an earth connection, touch current leakage measurements should be carried out on all accessible conductive parts that are not connected to the earth.

Warning!

Touch current measurement should only be carried out after the earth connection of the unit under test has been checked and found to be satisfactory!

Dangerous voltages may exist on defective machines as well as on accessible conductive parts that are not connected to earth!

Note

Touch current measurement should be carried out on the following accessible conductive parts:

• None.

2 Function

2.1 Heating control (R1, R2, R3)

Safety features:

If the fill ring temperature sensor (1R30) is defective, the heating is not activated.

The heating is switched off as soon as the heating relay is switched on for more than 5 s without the fan relay being activated.

The heating has a reswitch-on delay of 10 s and is switched off before, during and after a reversing pause.

2.2 Temperature limiter (F2)

Vented dryer:

Three 3/4 inch temperature limiters, 175°C, with manual reset via pushbutton, located in the heater channel next to the heater bank.

Condenser dryer:

Two closed 3/4 inch temperature limiters, 170°C, with manual reset via pushbutton, located on the heater bank.

2.3 NTC temperature sensor - Fill ring (1R30)

If the fill ring temperature sensor registers a drying air temperature less than 15°C or greater than 160°C, it is assumed to be defective.

2.4 NTC temperature sensor - Heater bank (2R30)

An open circuit at the heater bank temperature sensor (2R30) can only be registered with a temperature greater than 14°C. As during operation lower temperatures can exist, the sensor is only checked when the heating has operated for at least 1 min.

If a short circuit exists at the heater bank temperature sensor (2R30), this is equivalent to a temperature of 250°C and the heating is immediately switched off.

2 Function

2.1 Overriding time control

After programme start, an overriding time control of approx. 180 min applies to all residual moisture drying programmes.

After this time has expired, the dr ying programme is cancelled and the cooling stage for faults is activated. The anti-crease action phase is cancelled.

The fault is saved and can be called up in the service mode.

2.2 No-load recognition

No-load recognition and registration of very dry laundry can only take place with residual moisture drying programmes.

The programme is cancelled, a cooling phase is started and the buzzer sounds intermittently.

2.3 Insufficient air flow measurement

During warming up, the temperature increase at the heater bank temperature sensor (2R30) is monitored.

If the air path is blocked, this temperature increases rapidly and a fault is registered. The fault indication Insufficient air/Leakage is displayed.

2.3 Payment system

The tumble dryer is pre-fitted with the requirements for operation in conjunction with a payment system.

Payment system (programme operation):

The payment system provides the machine with a “start permitted” signal. After the programme has been started, it continues without further influence from the payment system.

L` 1

For further details, see Payment system (programme operation), 090 4.2.

Payment system (timed operation):

The payment system provides the machine with a constant “operation permitted” signal throughout the period of timed operation that has been purchased.

The programme continues so long as the signal is provided.

If the signal is interrupted, the programme and time left are stopped and the machine components are switched off.

For further details, see Payment system (timed operation), 090 4.3.
