Please read this Instruction Manual carefully and thoroughly forthe correct and optimum use of this product. Kindly keep this manual in aconvenient place for quick reference.WARNING● Never use this product as a sensing device for personnel protection.● In case of using sensing devices for personnel protection, use prod‑ucts which meet laws and standards, such as OSHA, ANSI or IECetc., for personnel protection applicable in each region or country.1 Compliance with standardsThis product complies with the following standards andregulations.● For the EU: EMC Directive 2004/108/EC● For the US and Canada:ANSI/UL60947‑5‑2, CAN/CSA C22.2 No.14● For Korea: S1‑G‑1‑2009, S2‑W‑5‑2009* In case you require a UL listing mark or C-ULlisting mark, use a class 2 power supply unit.2 Part descriptionFX-501□1 2 3 4567891 Operation indicator for sensing output (orange)2 Digital display (green/red)3 UP key (+) Functions:● Teach● Fine adjustment of the threshold value● Select settings4 DOWN key (–)5 MODE key Functions:● Select modes● Cancel6 SET key Functions:● Teach● Save selected settings7 Mode indicator PRO mode (yellow), see page 68 Mode indicator CUST (custom) mode (yellow), see page 59 Mode indicator L /D (Light‑ON/Dark‑ON) mode (yellow)FX-502□ and FX-505□-C21 2 3 4 5678901, Sensing output 1 (lit if output is active)● Orange: Sensing output is operating2 Sensing output 2 (lit if output is active)● Orange: Sensing output is operating3 Digital display (green/red)4 UP key (+) Functions:● Teach● Fine adjustment of the threshold value● Select settings5 DOWN key (–)6 MODE key Functions:● Select modes● Cancel7 SET key Functions:● Teach● Save selected settings8 Mode indicator PRO mode (yellow)9 Mode indicator CUST (custom) mode (yellow)0 Mode indicator L /D (Light‑ON/Dark‑ON) mode (yellow)* To toggle the key lock function ON/OFF, press the SET and theMODE key together for 3 seconds.3 MountingInstallation to a DIN rail1. Attach the railing on the rear of the ampli‑fier to the DIN rail.2. Push the amplifier in the direction of thearrow as illustrated so that it attachessecurely. 1.2.Removal from a DIN rail1. Push the amplifier forward.2. Lift the front part of the amplifier up.1.2.Connecting the fiber cable* The attachments to the fiber cables need to be fitted BEFOREyou insert the fibers into the amplifier. For details, refer to theinstruction manual enclosed with the fibers.1. Snap the fiber lock lever 1 down asfar as it will go.2. Insert the fiber cables slowly into theinlets until they stop (see note).3. Return the fiber lock lever to theoriginal position.2.1. 3. 123* With the coaxial reflective type fiber, such as FD-G4 or FD-FM2,insert the single core fiber cable into the inlet for the emitter 2(inlet on the amplifier is labeled “P”) and the multi-core fibercable into the inlet for the receiver 3. If they are inserted thewrong way round, the sensing performance will deteriorate.
