Filed: 1988-07-12
Abstract: The panel employed (1) incorporates indicator lamps or leds (58R,58L,R,L,54,54q,2,4,EMERG,Felkopplad (incorrectly connected), SERV), and possibly a sound producer. Between the insert plug and the panel extends an electrical multiconductor. Pressure monitors are connectable to the coupling box on the vehicle for compressed air transmission, and are connected also into the electrical system in which the indicator lamps or LEDS show whether a correct or fault coupling of the compressed air lines has been effected. Such monitors close, one at 2 bars, and the other at 4 bars, that closing at 2 bars monitoring pressure for brake applicatoin, and that closing at 4 bars monitoring the pressure for brake release. A multi-vibrator circuit produces a flashing effect of the indicator lamps when the compressed air connection is faults, and also causes at that time the sound producing unit to function.
