Fireye® NX3100 1052328

The Fireye® NEXUS™ integrated controller is a microprocessor-based, flame safeguard and parallel positioning combustion controller built-into one compact, user configurable package. The system consists of the controller, display, wiring sub-panel, temperature/pressure sensors, servo motors and comfire software. The flame safeguard portion of the control package provides burner sequencing including safe start check, proof of main valve closure, selectable main gas safety proving sequence, supervised pre-purge, low fire starting position, pilot and main trials for ignition, main flame supervision and post purge. Safety event timings are provided to meet North American and CE standards. Time proven Fireye® flame scanners and amplification circuits using UV, UV-self-check and infrared sensors, provide fast reliable scanning of most commonly burned fuels. Ten user defined auxiliary inputs provide supervision of safety critical and non-safety critical inputs. Control of up to four channels using an independent servo motors for each controlled element allows precise positioning, accurate to 0.1 s, of the fuel and air metering devices over the burner's firing range. One of two fuel profiles can be selected for each fuel channel with 24 positions per profile including closed, purge, ignition (Preferred Start™), low fire and an additional 20 intermediate points from low to high fire. The individual servo-motor's position and speed are verified and lockout will occur should either of these parameters be exceeded.
