Service Manual TD70 Component descriptions Components and function description Here we describe the function and specification of the most important components. Certain components are found only in more highly specified machines or in particular markets. See the Troubleshooting chapter for fault and information codes. CU (Control Unit) The CU (Control Unit) functions as both a control panel and a logic component.
Service Manual TD70 Component descriptions Thermostat Reset Overheating cut-out EMC filter The filter is installed next to the cable fasteners where the connection cable enters the machine. The filter consists of a number of coils, condensers and resistors. Purpose: To eliminate electromagnetic interference to and from the machine. Overflow guard The overflow guard comprises a microswitch triggered by a float.
Service Manual TD70 Component descriptions Door switch The door switch is located in a holder in the middle of the front support and is activated by a pin in the front door. The switch is normally open and closes when the door is closed. If the front door is opened during operation the CU stops the drying program. The program starts from the beginning if restarted. Purpose: To prevent the machine from running while the door is open.
Service Manual TD70 Component descriptions Heat pump (HP) Certain types of machine are fitted with heat pump systems. These systems are closed circuits that are replaced by replacing the machine’s base plate with a new module. The function settings are adjusted in the service menu. 2 1B 1A Heating Water Circuit (HWC) A certain type of machine is adapted for connection to the building’s existing heated water supply (such as district heating) to reduce energy consumption.
