DEVICE PLACEMENT
●
This is the configuration when two or more sets of emitter and receiver facing
each other are placed. It is used for the case that there is a problem in wiring or
for system evaluation in case of addition of equipment.
It is used for system evaluation in case of addition of equipment.
WARNING
●
Refer to the examples of device placement given below and understand them
thoroughly before installing the devices. Improper sensor placement could cause
device malfunction, which can result in death or serious injury.
●
If this device is used in multiple sets, arrange them to avoid mutual interference.
If mutual interference occurs, it can result in death or serious injury.
<Example of device placement>
1) Install emitter and the receiver back
to back
2) Arrange the emitter and the receiver
vertically on opposite sides.

WARNING
Position the emitter and receiver so that their cables are aligned. Failure to do so
will cause the system to malfunction.

MOUNTING
CAUTION
The minimum bending radius of the cable is R5mm. Mount the device considering
the cable bending radius.
<Reference>
Mount the emitter and the receiver at the same level and parallel to each other. The ef-
fective aperture angle of this device is ±5° or less for a sensing distance of 3m or more.
<In case of using standard mounting bracket (MS-SFC-1) (accessory)>
1.
Remove the M3 countersunk head screw [with anti-loosening agent (length 4mm)]
which is attached to the back of the device.
2.
Decide the direction of the standard mounting bracket.
3.
Tighten with the M3 countersunk head screw [with anti-loosening agent (length
4mm)]. The tightening torque should be 0.3 N•m or less.

WIRING
WARNING
●
Earth the machine or the support where the device is mounted on to frame
ground (F.G.). Failure to do so could cause the malfunction of the device by
noise, resulting in death or serious injury. Furthermore, the wiring should be done
in a metal box connected to the frame ground (F.G.).
●
Take countermeasure against the system to be applied for this device so as not
to carry out the dangerous performance caused by the earth failure. Failure to do
so could cause invalid for the system stop, resulting in death or serious injury.
●
In order that the output is not turned ON due to earth fault of control output
(OSSD), be sure to ground to 0V side (PNP output) / +V side (NPN output).
CAUTION
Make sure to insulate the ends of the unused lead wires.
<Reference>
Use a safety relay unit or an equivalent control circuit in safety for FSD.
●
Power Supply Unit
CAUTION
Wire correctly using a power supply unit which conforms to the laws and standards
of the region where this device is to be used. If the power supply unit is non-con-
forming or the wiring is improper, it can cause damage or malfunction of this device.
<Reference>
A specialist who has the required electrical knowledge should perform the wiring.
The power supply unit must satisfy the conditions given below.
1) Power supply unit authorized in the region where this device is to be used.
2) Power supply unit SELV (safety extra low voltage) / PELV (protected extra low
voltage) conforming to EMC Directive and Low-voltage Directive.
(only for requiring CE marking conformation)
3) Power supply unit conforming to the Low-voltage Directive and with an output of
100VA or less.
4) The frame ground (F.G.) terminal must be connected to ground when using a
commercially available switching regulator.
5) Power supply unit with an output holding time of 20ms or more.
6) In case a surge is generated, take countermeasures such as connecting a surge
absorber to the origin of the surge.
7) Power supply unit corresponding to CLASS 2 (only for requiring
C
TÜV
US
Mark
conformation).
