Method for monitoring the functioning of a controlling and regulating system

摘要

The method is applied to a system with at least one sensor, which detects at least one measurement parameter representing the system and produces corresponding measurement values, electronics which receive the values and an actuator, which is driven by the electronics and acts upon the system. Test signals are supplied to the actuator by the electronics at defined time intervals. The actuator is displaced according to the signals and the corresponding sensor measurement values detected by the electronics as test values and compared with stored reference values. If the test signals deviate from the reference values by greater than a defined amount an error signal or warning is generated by the electronics.
