Function

NX610 is Nexus integrated combustion controller manufactured by Fireye. It integrates burner sequencing, flame safety monitoring and parallel positioning fuel-air ratio control into one unit. The controller manages pre-purge, ignition, flame supervision and safety shutdown sequence. CANbus bus wiring simplifies multiple servo actuator connections for air and fuel valves. Built-in PID control maintains boiler temperature or pressure setpoint. Optional oxygen trim adjusts fuel-air ratio dynamically to improve combustion efficiency and reduce emissions. It provides complete diagnostic logs and lockout fault codes for troubleshooting. Widely deployed on industrial boilers and process furnaces for burner management spare replacement.

Installation

Follow lockout/tagout safety procedure before installation. Mount NX610 controller inside control cabinet. Wire power supply, safety interlock inputs, fuel valve relay outputs. Connect CANbus cable to servo motors, connect flame scanner wiring according to Fireye wiring schematic. Complete configuration of fuel profiles, purge timing and safety parameters. Perform burner cold test and firing commissioning, verify servo travel and flame safeguard interlock function.
