8.1 Resetting the excess current switch
The 230 V and 120 V devices have built-in thermal excess-current switches which function as
(all-pole) fuses. When the overload protection is actuated, these switch the power switch to OFF,
but do not switch it on again automatically.
To switch on the excess current switch again, proceed as follows:
1. Switch off the centrifuge using the power switch.
2. Wait for at least 20 seconds and switch on the centrifuge again.
The excess current switch will be automatically reactivated and the centrifuge is ready for
operation.
