1.1 Safety Precautions Always observe
The PM-□25 / PM-□45 conforms to the international standard ISO 13849-1 (Category 1, PLc)
and can be used as a detection device to indirectly protect the human body.
This manual explains important rules that must be observed to prevent personal injury and prop-
erty damage.
■The hazards that may occur if the product is used incorrectly are described and clas-
sied by level of harm.
WARNING Risk of death or serious injury.
WARNING
●Do not use this product for an application where it directly detects the human body. Otherwise,
there is a risk of death or serious injury.
●When the human body needs to be detected for safety application, use products that conform to the
laws and standards related to human body detection for safety application in each country, such as
OSHA, ANSI, and IEC.
1.2 Handling Precautions
■In this manual, the following symbols are used to indicate safety information that must
be observed.
Indicates an action that must be taken.
Specications
●Before using this device, be sure to conrm the standards / regulations applied in the rele-
vant nation and region.
●Since parts or all of a human body may not be detected, use this product solely for indirect
protection methods only.
●Objects within the deadband region or outside of the detection area, and transparent objects
cannot be detected.
Usage environment
●Since the sensor is intended for use inside machines, no special countermeasures have
been taken against extraneous light. Please take care that extraneous light is not directly in-
cident on the beam receiving section.
Power supply
● Be sure to use a SELV (Safety Extra Low Voltage) power supply unit with this device.
Wiring
●All electrical wiring should conform to the regional electrical regulations and laws. The wiring
should be done by engineer(s) having the special electrical knowledge.
●Power supply and output wires for connecting to this device should be 0.3 mm2or greater
with a total length of less than 30 m.

WUME-PMSAFETY-1 1-7
●Cables that are 0.3 mm2or greater can be used for a length of up to 30 m, but since voltage
will drop as the cable gets longer, ensure that the power supply voltage at the end of the sen-
sor's included cable and at the terminal is within the rating.
Overall length: 100 m
Extension cable
Supply voltage:
4.5 V or more
5 to 24 V DC ±10%
Output
+V

-
0 V
●If there is a large surge generating equipment, such as, motor, solenoid, electromagnetic
valve, etc., in the vicinity of the micro-photosensor, use a surge absorber on that equipment.
Further, do not run the sensor cables along power lines and use a capacitor between +V and
0 V. Use the sensor after conrming that the surge has been eliminated.
● Do not use during the initial transient time (50 ms) after the power supply is switched on.
Operation
● In case this device does not perform properly, the operator should report this to the person in
charge and stop the machine operation immediately. The machine must not be operated until
correct performance of this device has been conrmed.
Maintenance and Inspection
● If the sensor is used in a place having excessive dust, periodically clean the emitting and re-
ceiving sections with a dry, soft cloth.
Other precautions
● This product has been developed / produced for industrial use only. This product must be dis-
posed of using environmentally-friendly methods in accordance with applicable disposal and
processing regulations of the country it is used in.

2.4 Cautions when using in a ISO13849-1 Category 3 PLd system
This product has been certied for use together with a Category 4 PLe safety controller / safety
relay unit, which means it fullls the requirements of Category 3 PLd. When using in this way,
be sure to use two sensors in a sensor redundancy conguration.
To prevent loss of safety functionality due to accumulation of faults, build a control system with
two redundant outputs which will stop the whole system when a discrepancy of output is detect-
ed.
Furthermore, before use, conrm that the calculated results of MTTFd and DCavg fulll the re-
quirements for Category 3, PLd.

WARNING
Do not use the two outputs of a single device as the two outputs for a redundant safety system.
When using this product alone, the safety system it is used in may stop functioning if there is a
sensor fault.
