An \u003cstrong\u003eSCR\u003c\/strong\u003e only conducts when it receives a \u003cstrong\u003egate pulse\u003c\/strong\u003e, so the \u003cstrong\u003etrigger board\u003c\/strong\u003e is the part that decides \u003cstrong\u003ewhen\u003c\/strong\u003e the \u003cstrong\u003epower devices\u003c\/strong\u003e switch. If the \u003cstrong\u003efiring signals\u003c\/strong\u003e are late, missing or uneven, \u003cstrong\u003epower conversion\u003c\/strong\u003e becomes \u003cstrong\u003eunstable\u003c\/strong\u003e, and equipment that depends on it can \u003cstrong\u003efail to start\u003c\/strong\u003e, \u003cstrong\u003efault out\u003c\/strong\u003e or \u003cstrong\u003etrip repeatedly\u003c\/strong\u003e. The \u003cstrong\u003e031-02060-002\u003c\/strong\u003e sits in York's \u003cstrong\u003eSCR trigger board\u003c\/strong\u003e numbering alongside the \u003cstrong\u003e031-02060-001\u003c\/strong\u003e and \u003cstrong\u003e031-02060-003\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eIdentify it by the \u003cstrong\u003ecomplete part number\u003c\/strong\u003e. York also uses a different trigger board, the \u003cstrong\u003e031-01472-000\u003c\/strong\u003e, in its \u003cstrong\u003evariable speed drive\u003c\/strong\u003e equipment, so \u003cstrong\u003eSCR trigger boards are not interchangeable by description\u003c\/strong\u003e. The \u003cstrong\u003e031-02060\u003c\/strong\u003e series is its own \u003cstrong\u003eboard family\u003c\/strong\u003e, so \u003cstrong\u003ematch the number printed on the board\u003c\/strong\u003e you are replacing and do not substitute by name.
