3.7.1 Lid lock device
The centrifuge can only be started when the lid is properly closed. The
electrical lock 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 chapter 7.1.1
- "Emergency lid release").

3.7.2 Standstill monitoring system
Opening of the centrifuge lid is only possible if the rotor is at a standstill.
This standstill is checked by the microprocessor.

3.7.3 System check
An internal system check monitors the data transfer and sensor signals with
regard to plausibility. The system continuously performs a self-check and
identifies malfunctions. Error messages are displayed as "Error" followed
by a code number (see chapter 7.2 - "Table of error codes").

3.7.4 Earth conductor check
For the earth conductor check, there is an equipotential bonding screw on
the rear panel of the centrifuge (see chapter 2.1.1 - "Functional and
operating elements"). An earth conductor check can be carried out by
authorized and specialized personnel using a suitable measuring
instrument. Please contact the service department (see chapter 7.3 -
"Service contact").

3.7.5 Imbalance monitoring system
The indication "Imbalance" in the rotor field and, in some cases, also a
sound signal indicate that the centrifuge is in the impermissible imbalance
range.The drive will be switched off in the acceleration phase or during the
run.

3.7.6 Temperature monitoring system
If the temperature inside the rotor chamber rises above 50°C, the drive
system will be switched off automatically. The centrifuge cannot be
restarted until it has cooled.

3.7.7 Rotor monitoring system
When a rotor number and, if applicable, a bucket number are selected, the
computer will automatically check whether the entered speed or the
entered gravitational field are permissible for the selected rotor.
