Abstract

The invention relates to a method for effecting an electronic drive control of a drive coil of a protection system using an electronic device which comprises a microcontroller. The aim of the invention is to increase the serviceable life of a protection system. To this end, the invention uses a randomly selected and constantly changing delay time (tx) that occurs after a time (t2, t3) at which the supply voltage is established on the electronic device.
