4.2.3 Procedure while error 14, from software version 1.76

If Error 14 occurs, there is a problem with the speed sensor. The centrifuge lid is closed for
undefined period of time and in the "rpm/rcf" (A-1) display shows the lettering "USEr GuidE" (see
Figure 31).
Figure 31
To reopen the centrifuge lid, switch off the device and wait until the rotor has come to a standstill.
Take from Point 2.3.3 Pre-Selection of Brake Intensity and Acceleration" the maximum deceleration
time of the respective rotor. Level 0 corresponds to unbreaked rundown, which occurs at error 14. If
the centrifuge lid is opened before standstill of the rotor, a following error can occur.
Once the rotor has come to a standstill, open the centrifuge lid with the emergency release. Proceed
as described in chapter 4.2.1, p 26. After opening the centrifuge lid, switch on the device again.
Error 14 and the lettering "USEr GuidE" should be eliminated.
If this error occurs again, please contact the service.
