5.1.6 Safety Devices
Apart from the mentioned passive safety devices due to the solid design, the
following active precautions are in place for your safety:
5.1.6.1 Lid Lock and Lid Closing Device
The centrifuge can only be started when the lid is properly closed. The electrical
locks must be locked. The lid can only be opened when the rotor has stopped. If
the lid is opened by way of the emergency release system during operation, the
centrifuge will immediately switch off and decelerate brakeless. If the lid is open,
the drive is completely separated from the mains power supply, i.e. the centrifuge
cannot be started (see 6.2.5 "Emergency Lid Release", page 40).
5.1.6.2 Standstill Monitoring
Opening of the centrifuge lid is only possible if the rotor is at a standstill. This
standstill is checked by the microprocessor.
5.1.6.3 System Check
An internal system check monitors the data transfer and sensor signals with
regard to plausibility. Errors are detected with extreme sensitivity and displayed
as error messages with a number on the speed display (see 6.2.6 "Error Codes",
page 41).
5.1.6.4 Ground Wire Check
For the ground wire check, there is an equipotential bonding screw on the rear
panel of the centrifuge. A ground wire check can be carried out by authorized and
specialized personnel using a suitable measuring instrument (see 4.2.2
"Connection“, page 22). Please contact the head of our service team (see 6.2.7
"Service Contact", page 42).
