They operate turbomolecular pumps TURBOVAC. The TURBOTRONIK NT 340 MA and NT 341 MA are prepared for operation with an additional temperature control unit. This temperature control unit is part of a temperature control which maintains the temperature of the TURBOVAC within a narrow control range. The TURBOTRONIK converts the single-phase mains voltage into a regulated DC power supply. The unit’s electronic circuitry then switches this DC power supply onto the four stator windings of the TURBOVAC’s com- mutatorless DC motor in a cyclical sequence. This electronic switching system uses Hall probes, and replaces the commutator normally found in DC motors. A digital controller keeps the speed of the motor constant. The TURBOTRONIK also powers and regulates the magnetic bearing unit. Switching the motor to the gen- erator mode keeps the magnetic bearing unit in operati- on even in case of a mains power failure. Both the TURBOTRONIK and the TURBOVAC are fitted with sensors to ensure reliable operation of the entire system. External control and monitoring equipment e.g. the LEYBOTRONIK I can be connected via floating plug- and-socket terminals located at the rear of the TUR- BOTRONIK. Both the remote control unit and the lines for the pump system’s status signals are connected here. These terminals also provide connections for controlling the forepump, the heater and valves. An RS-232 interface provides a further control and mon- itoring option. The unit also has a counter-current braking system for slowing down the pump when it is shut down. 2 GA 05.218/3.02 - 11/97 GA 05.218/3.02 - 11/97 Description 3 1.2 Standard Specifications TURBOTRONIK NT 340 M Mains voltage setting Cat.
