Un polo potrebbe gestire un ingresso di controllo, mentre l'altro potrebbe supportare una condizione distinta di interblocco o segnalazione.

La dichiarazione deve identificare il dispositivo o l'ingresso controllato, lo stato dei contatti richiesto a riposo, lo stato dopo l'azionamento e se entrambe le azioni devono avvenire esattamente durante la stessa operazione meccanica.

If a press is intended to return when released, that condition should be stated. If the control behaviour relies on retention, reset logic, or another system element, record the requirement without assuming that a family image or a generic term determines the mechanism.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Mounting information also has a defined reference. Keep the panel cutout, thickness, and terminal envelope on the same released drawing as the two-circuit description, so the electrical notes and mechanical interface are reviewed together.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"part-5-review-panel-layout-and-the-fields-that-belong-in-the-quote\">Parte 5.
