Finally, revolutionary scanner technology that simplifies your operations and provides
significant cost savings. Once again, COEN leads the way by developing the most advanced
flame scanning solutions while maintaining the highest quality standards.
Our latest design, the
i
scan, is a new scanner product that integrates the scanner and
signal processor into one package. By eliminating a separate signal processor,
i
scan
reduces cost and simplifies installation.
i
scan also cuts setup time with powerful, but user-
friendly, Windows-based software.
i
scan is suitable for both single burner and multiple
burner applications, and for gas, oil, coal, and other fossil fuels.
The Cost-Effective Solution
By integrating the signal processor and scanner
into a single housing,
i
scan provides the following
cost saving benefits:

Eliminates expensive control cabinet hardware

Field wiring minimized

Reduces technician training time

Easy installation reduces commissioning time

Control cabinet space freed for other equipment

No special cable required
The Rugged Solution
Like all COEN products,
i
scan is built to be durable and reliable. Solid state detector High reliability/low maintenance Eliminates electrical noise problems Electronic
self-checking
, no mechanical shutter Compact configuration allows easy positioning in tight burner front area EASI (Electronically Assisted Sight Indicator) simplifies sighting (NEMA 4, 4x Model) Lightweight design avoids the need for frequent realignment NEMA 4, 4x or for Class 1, Div 1 & 2, Group B, C, & D Hazardous Area
The microprocessor-based design, Windows-based software, and real-time
displays make
i
scan user-friendly. System status, individual burner status and flame
signal data are always at your fingertips.
The System Display PC-based interface All adjustments are digital Extensive diagnostics display View any number of burners Obtain information on learned
results and current status instantly Shows Flame-on / Background
