Abstract

The circuit connecting the coupling indicating lamp on the dashboard, to the coupling to be monitored has a verification contact other than the coupling pivot. The verification circuit has the pivot locking contactor mounted in series on the circuit ending at the indicating lamp. The circuit has also a contact which controls a coupling connection element. This controlled connection element is formed by compressed air braking pipes. In series with the indicating circuit and the pivot locking contactor is a manocontractor (16) on the principal brake pipe and also one (17) on the automatic brake pipe.
