incident light intensity are set. (Note 1, 2)
Notes 1) The shift amount of 10% is an initial value. The shift amount can be set in PRO mode. Furthermore, the shift
value can be set in incident light amount. For setting method, refer to <PRO6> in “

ƔBe sure that detection may become unstable depending on the use environment
in teaching if less margin is applied.
ƔWhen teaching in Window comparator mode or Hysteresis mode, a setting has
to be made in PRO mode beforehand.
In case 1-point teaching, make sure to set the shift amount. (initial value is 10%
or 100)
For the setting, refer to <PRO6> in “
18
PRO MODE OPERATION DESCRIPTION.”
ƔTeaching can be set in RUN mode.
This is basic teaching method.
Stable sensing is possible
1.

ƔTake 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.
ƔTake care that short-circuit of the load or wrong wiring may burn or damage the
product.
ƔDo 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.
Ɣ 7KHVSHFL¿FDWLRQPD\QRWEHVDWLV¿HGLQDVWURQJPDJQHWLF¿HOG
ƔVerify that the supply voltage variation is within the rating.
ƔIf 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.
ƔIn 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.

traneous noise since the sensitivity of that is higher than the other modes. Make
sure to check the environment before use.
ƔDo 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.
ƔExtension up to total 100m is possible. However, in order to reduce noise, make
the wiring as short as possible. When you extend the cable, be sure to use cables
which have 0.3mm2or more of conductor cross-section area. Set the power sup-
ply voltage while taking into account the voltage drop in the power cable due to its
resistance.
ƔMake sure that stress by forcible bend or pulling is not applied to the sensor cable
joint.
ƔThis product is suitable for indoor use only.
ƔAvoid dust, dirt, and steam.
ƔTake care that the product does not come in contact with oil, grease, organic sol-
vents such as thinner, etc., strong acid or alkaline.
