Control is carried out during one or more opening and/or closing movements of at least one leaf (1a,1b). Monitoring the activation zone (19) from the sensor unit (9), adjustments are carried out in evaluation and control (23,25, fig.3). The effective zones (19) are enlarged so sensitivity is increased in such a way that self activation is reached, and adjustments carried out, effecting a safety distance for preventing self activation. |
