Abstract (en)

[origin: WO8805496A1] In all processes used until now to drive a computer-controlled final control element in connection with a self-test of the computer, the final control element is at first maintained in a defined reference position and is only released to receive driving signals from the computer once the self-test has been completed. This results however in very long delays in the case of complex computer systems. According to the invention, the final control element is maintained in a fixed position only during a first part of the self-test, and is then driven by a temporary driving signal until the end of a second part of the self-test or until a failure is detected, whichever occurs first.
