Compatibility description: 502-03813-01 belongs to Fives Group CNC rack service module family. Compatible with Fives Group CPU boards, I/O boards and motion control boards. Widely installed on heavy Fives horizontal boring mills.

Function

Function description: 502-03813-01 is rack central service module manufactured by Fives Group. It converts AC input to stable regulated DC power to feed auxiliary logic and diagnostic circuits inside CNC rack. It continuously monitors power health and reports fault status back to CNC controller. Built-in multi-protection circuits prevent damage from power surge, overload and overheating. It is legacy central service spare part for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off main 240VAC input power. Insert 502-03813-01 module into rack slot and secure gold finger connector. Wire 240VAC power to terminal block. Restore AC power, verify POWER and OK LED indicators, test power output and diagnostic reporting function.

Interface

Interface list: Backplane gold finger connector, 240VAC input screw terminal block,on-board POWER / OK / DIAG / FAULT LED indicators for Fives Group 502-03813-01.

Diagnostic

Troubleshooting: No power output: Check AC incoming supply, blown fuse or loose power terminals. FAULT LED lit: Overcurrent trip, overtemperature shutdown or internal power component failure. Intermittent alarm: AC voltage fluctuation, aging capacitor or poor rack grounding.
