ABSTRACT:
The control circuit is provided with a signal transmitter for feeding a temporary disturbance signal to the controller 16, a selector which is selectively connected to the signal transmitter and a function transmitter and a disturbance indicator which switches the selector to the function transmitter in response to a signal from the signal transmitter falling outside a certain preset range of threshold values. The control of the circuit may be constructed in various manners.
