Apparatus for monitoring the proper operation of components of an electrical system carrying out the same or mutually corresponding actions

摘要

The apparatus monitors several system components for proper operation. Each of the system components to be monitored is assigned at least one dedicated monitoring device that can be operated independently of the system components to be monitored. Under all circumstances it is possible to detect reliably whether, and if appropriate, which of the system components to be monitored is operating in a faulty manner.
