  • Page 15: Functional Description Block Functions

    Functional Description Functional Description Block Functions The accuSpin™ 1R is a refrigerated, microprocessor controlled low speed laboratory centrifuge with maintenance-free induction drive motor. The unit is constructed as bench top model with an extensive range of accessories. The centrifuge is build on a low vibration solid polymer bottom plate, the housing is made of sheet steel and surrounds the bottom plate completely.

  • Page 16: Main Board Functions

    Functional Description Main Board Functions The main board is mounted on a metal plate behind the front panel. The components on main board are arranged in following groups (see wiring diagram page 4-2 and 4-3) • Board fusing (2x 15 Amps. slow blown) •...
  • Page 17 Functional Description Main Board Functions (continued) • Frequency Converter The motor is provided 3-phased with chopped direct voltage blocks. These blocks are variable in frequency and pulse width modulation and are dephased to 120° between the motor windings. Beginning with low frequency and small pulse width chopped blocks, both parameters will be increased up to the operators set speed.

  • Page 18: Key And Indication Board

    Functional Description Key and Indication Board The key and indication board is mounted behind the front panel. A special micro controller is located on this board controlling the 7-segment displays, the control key LED’s and the operating keys. The communication with the central processor on the main board takes place via serial data lines in both directions (plug XI).

  • Page 19: Speed Detection Board

    Functional Description Speed Detection Board The speed detection takes place opto-electronically through a slot in the motor shaft. A light-emitting infra-red diode and a photo-transistor are mounted on the speed detection board and located on opposing sides of the motor shaft (see page 4-9). So 2 pulses per motor revolution are generated, by which the micro controller calculates the real rotor speed or rcf value.
