OPTICAL COMMUNICATION
● When the setting of data bank loading / saving, copy setting, or copy action
setting is conducted via optical communications, cascade the sub amplifiers
right side to the main amplifier as follows.
However, in case using data bank loading / saving, use
FX-502
□ or
FX-505
□
-C2
as main amplifier.
● If an amplifier is under any of the following conditions, the setting of data bank
loading / saving, or copy setting cannot be carried out.
• Copy lock setting is set to copy lock ON “
.”
• Digital display is blinking
• External input setting of main amplifier is set to
“
.
” (Only data-
bank loading / saving)
● When communication protocol of a
sub amplifier is set to communication
emission halt “
” the setting
of data bank loading / saving, or copy
setting cannot be carried out to sub
amplifiers subsequent to the mentioned
amplifier.
● Make sure to mount closely like follows
since interference prevention function is
conducted by optical communication.

ucts so that they are in order of Group A, B, D and C as shown in the right fig-
ure. This product is included in Group D.

● As for the products that are located between different groups, affix the ampli-
fier protection seal

corresponding product.
● Within each group, identical models should be connected in a lump.

INTERFERENCE PREVENTION FUNCTION
● This device incorporates an interference prevention function by setting different emitting
frequencies different from an interference prevention function by optical communication.
● For Interference prevention function setting procedure, refer to
<PRO5>
in
“
PRO MODE OPERATION MANUAL
.”
● Possible number of amplifiers for interference prevention function is different
as shown in table below.

● In case putting in more amplifiers than limit of interference prevention function,
put the amplifier protection seal to amplifier which is adjacent of end of an ampli-
fier that the interference function is valid or set OFF in communication protocol
setting of the end of amplifier that the interference prevention function is valid.
Example: Putting in 12 of this device and set STD of response time setting.
• Possible number of interference prevention is 4.
Put the amplifier protection seals 4th and 5th amplifiers and between 8th
and 9th amplifiers or change the communication protocol setting of 4th and
8th to OFF since interference prevention works from 1st to 4th, from 5th to
8th and 9th to 12th.

ERROR INDICATION
● In case of errors, attempt the following measures.
Error
indication
Description
Remedy
EEPROM is broken or reached the end of its
working life.
Please contact our office.
EEPROM writing error
Load of the sensing output 1 is short-circuited
causing an over-current to flow.
Turn OFF the power and check the load.
Load of the sensing output 2 is short-circuited
causing an over-current to flow.
Communication error when the amplifiers are
mounted in cascade.
Verify that there is no loose or clearance between
amplifiers.

munication unit and amplifiers.
Verify that there is no loose or clearance between

CAUTIONS
● This product has been developed / produced for industrial use only.
● Make sure that the power supply is OFF while adding or removing the amplifiers.
● Take care that if a voltage exceeding the rated range is applied, or if an AC
power supply is directly connected, the product may get burnt or be damaged.
● Take care that short-circuit of the load or wrong wiring may burn or damage the product.
● Do not run the wires together with high-voltage lines or power lines, or put
them in the same raceway.
This can cause malfunction due to induction.
● The specification may not be satisfied in a strong magnetic field.
● Verify that the supply voltage variation is within the rating.
● If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
● In case noise generating equipment (switching regulator, inverter motor, etc.)
is used in the vicinity of this product, connect the frame ground (F.G.) terminal
of the equipment to an actual ground.
● The ultra long distance (U-LG, HYPR) mode is more likely to be affected by
extraneous noise since the sensitivity of that is higher than the other modes.
Make sure to check the environment before use.
● Do not use during the initial transient time (H-SP, FAST, STD: 0.5 sec., LONG,
U-LG, HYPR: 1 sec.) after the power supply is switched ON.
● Use same power supply when mounting adjacently.
● Extension up to total 100m is possible. When you extend the cable, be sure the power sup-
ply voltage is 12V DC or more and use cables which have 0.3mm
2
or more of conductor
cross-section area. However, in order to reduce noise, make the wiring as short as possible.
● Make sure that stress by forcible bend or pulling is not applied to the sensor
cable joint and fiber cable.
● This product is suitable for indoor use only.
● Avoid dust, dirt, and steam.
● Take care that the product does not come in contact with oil, grease, organic
solvents such as thinner, etc., strong acid or alkaline.
● This product cannot be used in an environment containing inflammable or ex-
plosive gasses.
● Never disassemble or modify the product.
● This product adopts EEPROM. Settings cannot be done 100 thousand times
or more because of the EEPROM’s lifetime.
