System compatibility502-02813-00 belongs to Giddings & Lewis NumeriPath CNC family. Compatible with matching rack backplane, executive CPU and operator station boards. Widely used on vintage heavy G&L horizontal boring mills for probe and analog measurement functions.

Function502-02813-00 is digitizing input module manufactured by Giddings & Lewis. It acquires analog signals from machine probes, transducers and analog sensors, converts analog signals into digital values via onboard A/D converter, then transmits digitized data to CNC main processor over backplane bus. It enables part digitizing, workpiece probing and analog monitoring functions for heavy machine CNC control.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack +5V and ±15V power supply. Insert 502-02813-00 board into rack slot and secure gold finger connector. Wire analog input sensors with shielded cables. Perform channel calibration via CNC software, run self-test and verify probe/analog sampling function.

InterfaceBackplane gold finger connector,multi-channel analog input terminal block,on-board POWER / ACT / FAULT LED indicators for Giddings & Lewis 502-02813-00.

DiagnosticNo analog reading:Check ±15V reference supply, sensor wiring or damaged A/D channel. FAULT LED lit:Backplane communication failure, A/D conversion error or analog signal overload. Unstable sampled value:Shielding failure, ground loop interference or transducer fault.
