Flame Scanners


Spectrum VIR VI – Scanner Module

The Spectrum VIR VI scanner module utilizes a microprocessor to continuously monitor signals from the viewing heads. Using real-time spectral recognition algorithms and user defined rules, the scanner module detects the flame condition and provides analog and digital flame status signals for the boiler control system. Each module has two independent channels and can monitor two separate viewing heads.

Each module has five available flame output relays (Form A) and two isolated analog outputs. For dual fuel applications, each module has four discrete inputs. These inputs are typically used to switch between preset configurations when a different fuel is selected.

The scanner module is powered by redundant 24VDC supplies to ensure uninterrupted operation.

The scanner module is backed up by a number of hardware safeties:
- An independent on-board watchdog timer is used to ensure the continuous integrity of the flame scanner system.
- A hardwired minimum brightness requirement ensures constant "black furnace" protection.
- Any internal fault will result in a no-flame condition.
