The system consists of\n the Controller, Display, Temperature / Pressure Sensors, Servomotors, and optional ComFire2 Software.\n\n The Flame Safeguard portion of the control package provides burner sequencing including safe start check, proof\n of main valve closure, selectable main gas safety proving sequence, supervised pre-purge, low fire-starting\n position, pilot and main trials for ignition, main flame supervision, and post purge. Safety event timings are\n provided to meet North American and CE Standards. Time proven Fireye Flame Scanners and amplification\n circuits using UV, UV-Self Check, and Infrared sensors, provide fast reliable scanning of most commonly burned\n fuels in addition Fireye Self Checking CANbus sensor may be used for simplified wiring. For exotic fuels and\n applications, the NX6100 is also compatible with Fireye Phoenix and Insight Integrated Flame Scanners. Seven\n low voltage and two-line voltage user defined auxiliary inputs provide supervision of safety critical and non-safety\n critical inputs. A large menu of alarm messages provides enhanced diagnostics.\n\n Control of up to four profiles using an independent Servomotor for each controlled element allows precise\n positioning, accurate to 0.1o, of the fuel and air metering devices over the burner’s firing range. Each profile can\n be defined to include up to 10 servomotors. Profiles can be configured to share common fuel servomotors or as\n independent (one profile per fuel) and are not limited by fuel. Up to 24 positions per profile including: Closed,\n Purge, Ignition (Preferred Start), Low Fire and an additional 20 intermediate points from low to high fire. Each\n individual servomotor’s position and speed are verified, and lockout will occur should either of these parameters\n be exceeded. All servomotors are controlled via secure CANbus communications link.\n\n Modulation control is provided via the pressure/temperature sensor’s input. The Fireye NX1025, NX1030 or\n NX1040 sensors provide checking circuits for fail safe operation. Two PID setpoints are available for the chosen\n modulation input, selectable up to two decimal points. Track modulation is available for those applications\n requiring less precise control.\n\n The NX6220 and NX6330 Twelve-Key Display allows commissioning and current status of the system through\n the use of its tactile membrane keypad. Multi-function keys allow the commissioning to engineer the ability to\n access the various Ratio Modes and Option Select menus. The four-line OLED Display clearly illuminates the\n Control Variable, Firing Mode, Fuel Selected and Hours Run. It further allows the Boiler Operator access to the\n Auto/Manual selector, Motor Data (servo positions) and other operational parameters such as System Sequence\n Position, Valve Proving Sequence Status, Gas Pressure, Flame Signal, Modulation Rate and Setpoint, as\n necessary.\n\n Multiple Boiler Sequencing is accomplished through an RS485 Communications bus using ComFire2 software.\n Lead/Lag and Standby set points for up to four (4) boilers can be configured.\n\n When replacing control with firmware version 1.307 with firmware version 1.4XX it is required that obsolete\n displays NX610/NX6110 be removed and replaced with a NX6220/NX6330 this is not necessary if a NXTSDXXX\n touchscreen is present.\n\n\n\n\n1 NX6100 Fireye - Introduction V1pt4D Commissioning Manual version 1.4\n© 2025 Fireye\n\f Introduction\n\n Part No Description\n INTERGRATED PARALLEL POSTIONING CONTROL\n NX6100 Standalone parallel positioning controller, with up to ten (10) selectable\n function CANbus servos for custom applications.\n NXDBVSD VFD daughterboard with two VFD channels, one analog output, two encoder\n inputs, two programmable relays, isolated RS485 – Modbus RTU.\n NXMBDB MODbus RTU interface cards for NX6100/PPC6000.
