Safety Summary
Quick Release Connector and Hazardous Area
SF910i (quick release connector versions), when installed in hazardous area, cannot
be dis-connected under power. The plug is equipped with a locking allen screw that
must be unscrewed before releasing the connector.
Ex certified products (Refer to datasheet 4JZZ438101A0001 SF910i Flame Scanner
Uvisor for detailed product coding) must be handled as in SF910i Safety Instruction
Manual (EC-DOC-G041MAN033).
Ex Certified Fiber Optic Versions
IECEx/ATEX certified SF910i for fiber optic versions (Refer to
EC-DOC-G018PCL402) must be mandatorily used together with the ABB
IECEx/ATEX certified fiber optic. Otherwise, the certification is invalidated.
Ex certified products (Refer to datasheet for detailed product coding) must be handled
as in SF910i Safety Instruction Manual (EC-DOC-G041MAN033).
Do not disassemble or remove the electronics from the enclosure.
It is absolutely forbidden to un-tight/remove the two screws that hold the electronic
boards during operation.
There are no configurable/serviceable parts inside.
Flame Failure Response Verification
For safety reasons, the user is requested to prove the Flame Failure Response
Time (FFRT) of the SF910i under any burner load/fuel conditions and under any
selected file of parameters. For EN298 application, the user need to set the DELAY
DROPOUT parameter to <= 0.9s to fulfill the requirement of EN 298 that the FFRT
shall not exceed one second. If there are further adjustments of the flame detector
(DELAY DROPOUT), do not cause the time to rise above one second.
Installations shall comply with the requirements of the local codes and jurisdictional
authorities.
For instance, in U.S.A., the installations shall comply with the requirements of the
relevant edition of the National Electrical Code (NFPA 85).
Do not open when an explosive atmosphere is present.
"Ex" certified products (Refer to datasheet for detailed product coding) in which "Ex"
classified area must not be opened when an explosive atmosphere is present.
