104FX-301FiberPRECAUTIONS FOR PROPER USE.Fiber cutter (FX-CT2)• To cut the fiber cables, insert them from the direction shown below.(Fiber cable insertion direction)1 Slide part of the fiber cutter fully upward till it stops.2 Insert the fiber cables, mounted in the attachment, tillthey stop.Take care that there are separate fiber insertion cableholes for "2.2 mm "0.087 in and "1.0 mm "0.039 in or"1.3 mm "0.051 in fiber cables.3 Slide part of the fiber cutter down to cut the fibers.Notes: 1) The fiber cables should be cut in one stroke.Notes: 2) Once a fiber cable is cut off at a hole, do not use the hole again. Ifused, it degrades the cut surface quality and the detectability maydeteriorate.Notes: 3) The blade cannot be replaced. Please purchase an additional fibercutter, if required.Notes: 4) Note that the sensing range may be reduced by up to 20 %depending on the cut condition. Hence, decide the setting distanceby taking sufficient margin.How to use fiber cutter (FX-CT2)( )Seal type slit mask for FT-WA30/A30, FT-WA8/A8• Two types of slit masks are enclosed. (one type forFT-A30 and FT-WA30) Apply the enclosed slit mask whendetecting small objects or as measures not to saturate theemitted light amount for short-range sensing.However, the sensing range is reduced when the slit maskis mounted.As the slit mask is seal type, stick it by aligning theprojection of the slit mask with the upper portion of thefiber head, as shown in the figure below.Sensing range when mounting slit mask [with FX-301(P)]MountingSlit masksFT-WA30/A30: 2,500 mm 98.425 in (LONG) / 1,000 mm 39.370 in(STD) / 600 mm 23.622 in (FAST) / 200 mm 7.874 in(S-D)FT-WA8/A8: 400 mm 15.748 in (LONG) / 200 mm 7.874 in (STD) / 140 mm5.512 in (FAST) / 70 mm 2.756 in (S-D) (0.5 12 mm0.0200.472 in slit mask)FT-WA8/A8: 800 mm 31.496 in (LONG) / 400 mm 15.748 in (STD) /280 mm 11.024 in (FAST) / 140 mm 5.512 in (S-D)(112 mm 0.0390.472 in slit mask)Vacuum type fiberLeakage: 1.3310 –10 Pam3/sec. [He] or less1 Make two holes on the vac-uum tank wall (chamberwall or flange).Note: The hole diameter must be from" 5.5 to " 6.0 mm " 0.217 to"0.236 in.2 Mount the FV-BR1 photo-terminal on the vacuum tankwall.Notes: 1) The attached O-ring must be mounted.Notes: 2) The O-ring must be used at the atmospheric side.Notes: 3) The tightening torque should be 0.58 Nm or less.3 Mount the FT-J6 atmospheric side fibers on theatmospheric side of the FV-BR1 photo-terminals.Notes: 1) The fixing nuts must be tightened securely. If not, the sensingrange may decrease.Notes: 2) The tightening torque should be 0.58 Nm or less.4 Mount the vacuum type fibers on the vacuum side of theFV-BR1 photo-terminals.Notes: 1) The fixings rings of the vacuum type fibers must be tightenedsecurely. If not, the sensing range may decrease.Notes: 2) The tightening torque should be 0.58 Nm or less.5 Fix the fiber head of the vacuum type fiber.Note: The maximum tightening torque should be as given below.Tightening torque0.29 Nm0.58 NmM2.6M4M6ConfigurationMountingAA
