Logic 3 531 3722A Circuit Board
 |
The 3‑531‑3722A is a Cincinnati Milacron logic controller board used as the timer/counter module in industrial molding machines and other process equipment. Common failures on this board include burned or tripped ICs (especially the timer core), degraded capacitors, and intermittent LED indicator faults that can mask underlying relay or counter issues. First‑check diagnostics: verify input power to the board (24 VDC/AC as specified), inspect for visible component damage or solder bridges, and read any status LEDs or error codes displayed on the machine’s HMI; if the board is powered but no logic signals are present, test the output relays with a multimeter.[oss-gpt-20b] |
