microprocessors.
Your insulin pump is controlled by two
microprocessors. The safety concept is
based on one processor (supervisor
processor) supervising the other (main
processor). Whenever a defect or fault
occurs in the main processor, it is iden-
tified by the supervisor processor. The
motor is immediately switched off and
an error E7: ELECTRONIC ERROR
occurs. Conversely, the main processor
can also determine at any time whether
the supervisor is working correctly. The
motor also constitutes an important
safety component, as the combination
of the main and supervisor processor
and brushless motor provides the best
possible reliability and accuracy in
insulin delivery.
