Si cette tension est interrompue, le VFD cessera de communiquer avec le PCM. Le PCM continuera \u00e0 fonctionner pendant une courte p\u00e9riode au cas o\u00f9 cette interruption serait intermittente, mais si la tension n'est pas r\u00e9tablie, le syst\u00e8me s'arr\u00eatera et d\u00e9clarera le code 24-58. Le d\u00e9faut dispara\u00eetra une fois que l'alimentation de 5V CC sera r\u00e9tablie au VFD. L'alimentation de 5V CC provenant du PCM est \u00e9galement partag\u00e9e avec les capteurs de pression aliment\u00e9s en 5V CC.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mod\u00e8les 26VNA\/27VNA<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lorsque le code 24-58 est actif, d\u00e9brancher le faisceau de communication du PCM au variateur de fr\u00e9quence (VFD) et mesurer la tension entre la broche 3 (GND) et la broche 4 (+5 V CC) \u00e0 l'extr\u00e9mit\u00e9 de raccordement du VFD. Si une tension est pr\u00e9sente, rebrancher le faisceau, couper puis r\u00e9tablir l'alimentation, et v\u00e9rifier si le d\u00e9faut est toujours pr\u00e9sent. Si c'est le cas, le VFD devra \u00eatre remplac\u00e9. Si aucune tension n'est pr\u00e9sente \u00e0 l'extr\u00e9mit\u00e9 VFD du faisceau, v\u00e9rifier la pr\u00e9sence d'une tension au connecteur (header) du PCM. Si aucune tension n'y est pr\u00e9sente, d\u00e9brancher tous les autres capteurs du PCM jusqu'\u00e0 ce que le d\u00e9faut disparaisse. Le capteur dont le d\u00e9branchement fait dispara\u00eetre le d\u00e9faut doit \u00eatre inspect\u00e9 pour d\u00e9celer d'\u00e9ventuels dommages ; un court-circuit est probablement pr\u00e9sent dans le faisceau. Une fois que tous les capteurs sont d\u00e9branch\u00e9s et que le d\u00e9faut est toujours pr\u00e9sent, confirmer que le +5 V CC n'est pas pr\u00e9sent sur la carte PCM ; si c'est le cas, remplacer le PCM.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mod\u00e8les 27VPA<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lorsque le code 24-58 est actif, d\u00e9branchez tous les autres capteurs du PCM jusqu'\u00e0 ce que le d\u00e9faut disparaisse.
