System compatibilityPPC4000-230V belongs to Fireye Nexus PPC4000 combustion control family. Must pair with Fireye BurnerLogix flame safeguard controllers. Compatible with FX/NXC servo actuators, PXMS pressure transmitters, PSA pressure switches and flame scanners. Applied for gas, oil and dual-fuel industrial boilers and process furnaces. Widely used for combustion system upgrade and spare replacement.

FunctionPPC4000-230V is parallel positioning fuel-air ratio controller manufactured by Fireye. It controls fuel valve and air damper servomotors independently. 24-point programmable curve optimizes air-fuel ratio across full firing range to improve efficiency and reduce emissions. Built-in PID stabilizes boiler pressure or temperature. SD card supports program backup and restoration. It handles burner modulation positioning while external flame safeguard performs flame detection and burner safety sequence. Supports VFD and oxygen trim for energy saving. Widely deployed for industrial boiler combustion optimization and spare replacement.

InstallationFollow lockout/tagout safety procedure before installation. Mount PPC4000-230V inside NEMA rated control cabinet. Wire servo actuators via communication cable, connect analog/digital inputs strictly follow Fireye PPC4000 wiring manual. Program fuel curve and PID parameters, perform full stroke test and combustion tuning during commissioning.
