A trouble-shooting system for computer-controlled machinery includes a portable programmable testing unit (100). The unit (100) includes: a CPU (170); A/D (130) and D/A (132) converters connecting the CPU (170) to a voltage probe (34), for either measuring voltages on the machine or generating test voltages to be applied to the machine; a voice synthesizer (120) with headphones (24); a text line display (50), for instructing the user, a keypad (60) for the user to respond; a card slot (40) for accepting a memory card (42) which holds the test program, and may be dedicated to the machine (200) and hold a maintenance history; and a data bus connector (74). The data bus (212) from the machine's control computer (210) is disconnected for the test and coupled to the testing unit (100), which tests the computer as well as electromechanical devices of the machine (200).

Système de détection des pannes pour machines commandées par ordinateur se présentant sous la forme d'une unité programmable portative de contrôle (100). Ladite unité (100) comporte: un processeur central (170), des convertisseurs A/N (130) et N/A (132) reliant le processeur (170) à une sonde de tension (34) servant à mesurer des tensions sur la machine ou à fournir les tensions d'essai devant lui être appliquées; un synthétiseur vocal (120) muni d'écouteurs (24); un affichage de textes (50) informant l'utilisateur; un clavier (60) lui permettant de répondre; une fente d'introduction (40) d'une carte mémoire (42) contenant le programme de vérification (pouvant être propre à la machine (200) et contenir ses données de maintenance); et un connecteur (74) pour bus de données (212). Pendant la vérification, ledit bus (212) qui appartient à l'ordinateur de commande (210) de la machine est débranché et raccordé à l'unité de contrôle (100) qui vérifie l'ordinateur de la machine ainsi que ses organes électromagnétiques.
