Description
The Fireye NEXUS NX6100 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, Temperature/Pressure Sensors, Servo-Motors and optional 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. For exotic fuels and applications, the Fireye Nexus NX6100 is also compatible with Fireye Phoenix and Insight integrated Flame Scanners. Seven low voltage and two line voltage user defined auxiliary inputs provide supervision of safety critical and non-safety critical inputs. A large menu of alarm messages provides enhanced diagnostics.
Control of up to four profiles using an independent Servo-Motor for each controlled element allows precise positioning, accurate to 0.1o, of the fuel and air metering devices over the burner’s firing range. Each profile can be defined to include up to 10 servomotors. Profiles can be configured to share common fuel servomotors or as independent (one profile per fuel) and are not limited by fuel. Up to 24 positions per profile including: Closed, Purge, Ignition (Preferred Start), Low Fire and an additional 20 intermediate points from low to high fire. Each individual servomotor’s position and speed are verified and lockout will occur should either of these parameters be exceeded. All servomotors are controlled via secure CANbus communications link.
Modulation control is provided via the pressure/temperature sensor’s input. The Fireye NX1025, NX1030 or NX1040 sensors provide checking circuits for fail safe operation. Two PID setpoints are available for the chosen modulation input, selectable up to two decimal points. Track modulation is available for those applications requiring less precise control.
The NX6120 Twelve-Key Display allows commissioning and current status of the system through the use of its tactile membrane keypad. Multi-function keys allow the commissioning engineer the ability to access the various Ratio Modes and Option Select menus. The two line 20 character Vacuum Fluorescent Display clearly illuminates the Control Variable, Firing Mode, Fuel Selected and Hours Run. It further allows the Boiler Operator access to the Auto/Manual selector, Motor Data (servo positions) and other operational parameters such as System Sequence Position, Valve Proving Sequence Status, Gas Pressure, Flame Signal, Modulation Rate and Setpoint, as necessary.
