TCD210055AC Safety Considerations

• Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazards.
• ᜸ symbol indicates caution due to special circumstances in which hazards may occur.

᜸ Warning Failure to follow instructions may result in serious injury or death.

01. Fail-safe device must be installed when using the unit with machinery that

Universal AC/DC
may cause serious injury or substantial economic loss. (e.g., nuclear power
control, medical equipment, ships, vehicles, railways, aircraft, combustion
apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or fire.

Photoelectric Sensors
02. Do not use the unit in the place where flammable/explosive/corrosive gas,
high humidity, direct sunlight, radiant heat, vibration, impact or salinity
may be present.
Failure to follow this instruction may result in explosion or fire.
03. Do not disassemble or modify the unit.
Failure to follow this instruction may result in electric shock or fire.
04. Do not connect, repair, or inspect the unit while connected to a power
source.
Failure to follow this instruction may result in electric shock or fire.
05. Check ‘Connections’ before wiring.
Failure to follow this instruction may result in fire.

᜸ Caution Failure to follow instructions may result in injury or product damage.

01. Use the unit within the rated specifications.

Failure to follow this instruction may result in fire or product damage.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in electric shock or fire.
03. Do not use a load over the range of rated relay specification.
Failure to follow this instruction may result in insulation failure, contact melt,
contact failure, relay broken, or fire

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected
accidents.
• When connecting an inductive load such as DC relay or solenoid valve to the output,
remove surge by using diodes or varistors.
• Use the product after 0.5 sec of the power input.
When using a separate power supply for the sensor and load, supply power to the
sensor first.
• The power supply should be insulated and limited voltage/current or Class 2, SELV
power supply device.
• Wire as short as possible and keep it away from high voltage lines or power lines to

BEN Series
prevent surge and inductive noise.
• When using switching mode power supply (SMPS), ground F.G. terminal and connect
a condenser between 0V and F.G. terminal to remove noise.

PRODUCT MANUAL
• When using a sensor with a noise-generating equipment (e.g., switching regulator,
inverter, and servo motor), ground F.G. terminal of the equipment.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specifications’)
- Altitude max. 2,000 m
For your safety, read and follow the considerations written in the instruction - Pollution degree 2
- Installation category II
