Abstract (en)

[origin: EP1134715A1] The lamp circuit (2) has a control and evaluation unit for a monitoring device with two differently operated microcomputers (6,7), via which state signals are fed to the lamp circuit and that continuously check the signals for coincidence with true state signals. One of the microcomputers activates a test mode in the monitoring device unknown to the other microcomputer and checks the functions of the monitoring device in this mode.
