The elctronics of the LRE-PCB stabilizes the actual load of
the eddy current brake with the given accuracy.
The rotations per minute are monitored with a non
-contact hall sensor, the feedback signal of the strain
gauge is analysed and the actual brake force adjusted
accordingly.
The LRE board is mounted with the component side
towards the aluminium housing of the drive unit.
The microprocessor of the LRE board also generates the
interface signals for external communication (e.g. with PC
ECG or ECG recorders).
The BKE interface board (generating the nal RS-232 and
USB signals) is always connected directly to the LRE board.
