Service Manual TD70.C Component description 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.C Component description Tolerance: ±1% Reset Thermostat Overheating cut-out Co ver pla te ( 65 8x 48 3m m) Thermostat and overheating cut-out The thermostat is installed next to the heating element and is used to reduce the element output by turning it off if the ambient temperature exceeds 135°C (±5°C) for condenser dryers and 110°C (±5°C) for others.
Service Manual TD70.C Component description 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 programme. The programme starts from the beginning if restarted. Purpose: To prevent the machine from running while the door is open.
Service Manual TD70.C Component description Heating element The heating element is located in the rear section and consists of two separate heating coils. Each heating coil is made from resistance wire. Purpose: To heat the drying air to the right temperature. 2 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.
