Model Z 306 is a micro processor controlled cooled laboratory centrifuge. The actuation is a three phase asynchronous motor which is controlled by frequency converter. Model Z 306 has an independent error detection program, displaying possible errors and therefore supporting the trouble shooting process. -
Page 9: Control Board
The control board consists of one plate. The board can only be exchanged completely. If there is a defect you have to exchange the complete board. All signal lines lead to the control board. The PCB controls the entire centrifuge. Figure 2: Control board © Hermle Labortechnik GmbH Service Manual Z 306... -
