TD 73
Overheating cutout
The machine incorporates a manually-resettable overheating cutout, operating
at a temperature of 150°C.
Thermostat
The thermostat has an automatic reset and the breaking temperature is of
115°C. It is used for indication of fluff in the filter or in the condenser. See fault
signals F4. Not all markets.
Capacitor
The drive motor capacitor is of 8µF.
Buzzer
A built-in buzzer is fitted so that the end of the program can be indicated audibly
if required.
Lighting
An interior drum light is fitted and is operated by the door switch.
Temperature sensing
Machine temperature is controlled by a thermistor for exact control. If the ther-
mistor is loose or gets a short circuit, the program is stopped. See fault signal
F3.
Moisture sensing
A moisture sensor, measuring the humidity of the circulating air, controls the
drying process. The output from the sensor should be between 1-16 mV DC
when the machine is running. Other values from the sensor will stop the pro-
gram. See fault signal F5.
Interference suppression
The machine incorporates two RFI suppressors.
Starting relay
A relay mounted on the electrical components platform interrupts the power a) if
the machine overheats, b) if the door is opened or c) at the end of a program.
Mains cable
The mains cable is an RKK 3x1,5 or 5x1,5 mm
2
, with variants for different
markets.
Maximum operating time
In order to prevent the dryer from operating indefinitely (for whatever reason),
the maximum running time is 180 minutes, after which the program is
interrupted.See fault signal F2.
