Maintenance Recommendations:
Regularly inspect the DS200DCFBG2BNC for loose connections, dust accumulation, or physical damage. Clean the enclosure with a dry, static-free cloth to maintain optimal heat dissipation. Monitor the LED and neon indicators—steady green for power, blinking red for faults, and illuminated neon for blown fuses. Replace faulty fuses with GE-approved replacements (3A, 250 V) and test voltage levels at the TP test points using a multimeter. Periodically update the board’s firmware via GE’s ControlST software to access bug fixes and performance optimizations. For persistent issues, contact our technical support team for remote diagnostics or board replacement.
