System compatibility502-03419-00 belongs to Giddings & Lewis NumeriPath 8000 /8000B CNC family. Works with matching system backplane, CPU and servo interface modules. Widely used on vintage G&L heavy horizontal boring mills.

Function502-03419-00 is operator station board manufactured by Giddings & Lewis. It serves as the core processing board of the machine operator panel. It receives keypad/jog inputs from machinist, communicates with CNC main CPU, drives the front display to show real-time axis positions, G-code status and system alarms. It integrates DC/DC power converters and EPROM firmware storage to implement HMI logic. It is a legacy operator interface spare for old heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Disconnect system power. Install board into machine control rack, secure edge connectors. Check onboard DC/DC modules and EPROM chips before power-up. Load matching firmware, run board self-test and verify keypad, jog and display functions.

InterfaceBackplane gold finger connector,keypad/display interface port,on-board POWER / RUN / ALARM LED indicators for Giddings & Lewis 502-03419-00.

DiagnosticNo display output:Check onboard DC/DC converter failure or firmware EPROM fault. ALARM LED lit:Communication timeout with main CPU or PLD logic error. Keypad no input:Front panel wiring fault or sub-board SBX contact issue.

Product Brief502-03419-00 is Giddings & Lewis legacy operator station board for NumeriPath 8000 CNC system,for machine operator panel keypad processing and display control on heavy CNC boring mills,discontinued HMI PCB spare.
