Page 6: Product Features
Product Features The iScan3 flame scanner is designed to detect flame from fossil fuels such as natural gas, refinery gas, waste gas, fuel oils, biomass and coals. The iScan3 consists of an integrated viewing head and signal processor. No secondary signal processor or amplifier is required. - Page 7 LED STATUS INDICATORS; “Ring of Light”: The iScan3 is equipped with a highly visible LED status indicator ring. This “Ring of Light” communicates the scanner’s operating modes including FLAME SIGNAL STRENGTH, GAIN LEVEL (the amount of signal amplification), and WARNINGS/FAULTS. This ring aids with “sighting” the flame; or in other words: proper aiming of the scanner. This must be done with care to ensure that a good flame signal is present over a range of operating conditions.

Page 13: Wiring Instructions
Wiring Instructions All wiring shall be done in accordance with all applicable local and national codes, standards, and ordinances. The scanner has a quick connect cable. This cable does not require a flexible conduit if permitted by local authority. Connections for power, Earth Ground, and Flame Relay (N.O. and Common) are required for all applications. Use of the 4-20 mA outputs, Communications, and connections are “as-required”... - Page 14 Note 5 Connect the scanner Earth GND (Green/Yellow, 8, <H>) to EARTH GROUND. A short BRAIDED CONDUCTOR (alternately a short AWG #12 wire) is recommended. Note 6 All shields are tied to Earth Ground in the Control Panel only. ALL OTHER CONNECTIONS GREEN/YELLOW (8) <H>...

Page 18: Communications Wiring
Communications Wiring RS-485 Communication with the iScan3 is RS-485 via a USB to RS-485 Converter (PN 3425-057-01). RS-485 is a differential multi-drop network. For iScan3, the network is a half-duplex, 2-wire, echo-off configuration operating at 19200 KBAUD. The maximum allowable number of nodes on a given section of the network is 32 including the USB to RS-485 converter and any repeaters. If more than 32 loads are connected (1 USB converter, 1 RS-485 repeater and 30 iScan3s) then an RS-485 repeater is required between sections to boost the signal. -
