Quanta Max Multiple Burner Flame Input Module

The Quanta-Max Communication System is an economical way to monitor the flame inputs from up to 16 burners, outputting to one single burner flame safeguard system.

Application

The Quanta-Max Communication System is ideal for ovens, kilns, cabin heaters, and other furnaces that have multiple burners but just one fuel header safety shutoff valve. This system is not appropriate for boilers because NFPA 85 requires individual burner safety shutoff valves for multiple burner boilers.

Features

  • Multiple Burner System Monitors Up to 16 Burners
  • Model 5003-01T Accepts UV Scanners
  • Model 5003-03T Accepts Flame Rod Sensors
  • Accepts Honeywell, Fireye, Eclipse, PCI, or Preferred Flame Scanners
  • RS-485 Communication Interface
  • Display Each Sensor Flame Level (with LCD display)
  • Burner Sequence and Alarm Display
  • Isolated 5 Amp Relay Alarm Contact
  • Displays Each Sensor Flame Level
  • Optional History Logging of Previous Shutdowns
  • Built-in 120 VAC 50/60 Hz Supply
  • Small Panel Space Requirements
  • Ideal for PLC-based Flame Safeguard Systems

Specification

Multiple Burner Flame Input Module: System shall be capable of monitoring up to 16 flame scanner inputs and providing a single output signal to a separate flame safeguard controller. Input module shall accept flame scanner inputs from a variety of manufacturers and interface with varying flame safeguard controllers. Individual flame signal strength shall be indicated, and first-out annunciation shall be provided to determine which flame signal first fell below adjustable threshold levels.

Operation: System shall accept UV or flame rods signals from all major scanner manufacturers. The number of flame signals connected, and their trip thresholds shall be DIP switch programmable. The control shall interface with a separate 2 x 16 character LCD display, and provide a single “flame proven” signal to a separate flame safeguard controller. Flame proven logic shall be customizable per the application–programmed at the factory. Historical trending of the last 16 alarm conditions shall be provided.

Manufacturer: Flame input module shall be Preferred Utilties Mfg. Corp. of Danbury, CT, Quanta-Max system model number 5003-01T (UV sensors) or 5003-03T (flame rods). LCD display shall be Preferred Instruments QD485. Flame safeguard controller, if required, shall be 5004-890, 5004-795, or 5004-M series.
