摘要：In a circuit configuration for monitoring a plurality of coils and the final stagesfor actuating these coils, the coils are connected to the supply voltage by way of a jointsupply line and a joint relay. Connected to the supply line, by way of a high-ohmicresistor, is a test voltage source and a first potential monitor, by which the potentialprevailing on the supply line is determined after the voltage supply has been interruptedby opening the relay contact. A second potential monitor serves to monitor the properpotential changes on activation of the voltage supply by actuating the relay.
