Beschreibung
Zusammenfassung:	A method of operating a switching relay with inductive coils by a microprocessor control to prevent the transient electro-magnetic noise caused by the switching relay from resetting the microprocessor and restarting the program at the beginning. Prior to switching a relay a code is loaded in the memory of the control. After the relay switching noise causes a reset, the control detects the code and jumps back to its proper place without a disruption in its operation.
