Mechanical Pats (Dynamic System) :
The main motor is attached to the chassis with four special self threaded screws. In order to
drive drum a polv-y-V belt ise used between the motor pulley and drum There was used a
elastic belt. The drum is made of galvanized sheet steel. The drum group is mounted into the
front bearing house and rear bearing steel bracket, which is located rear panel. The heater is
mounted to the rear panel wtih two screws.
It is advised that the elastic Poly-V belt will be assembled max 3 times. Due to
damage on the belt on assembling, after 3 times please change the Poly-V belt
also.
Temperature Sensor ( NTC ):
Two NTC temperature sensor are used on electronic controlled dryers, one is located after the
door filter in suction canal, other is located in the heater. As the temperature of the surrounding
of NTC increases, its resistance decreases. At fixed temperature NTC will always have a
specified resistance within the tolerance. With the aid of this principle operates until the desired
temperature is reached. In this way, the selected program completes properly each time in
accordance with the program set an auxiliary function neither selected an is nor influenced by
air temperature etc.
Humidity Sensor:
Humidity level will be measured by the resistance of clothes. With this property of the humudity
sensor, its possible to check and control the humudity level precisely. It is driven by macro.
