Precautions For Safe Use - Omron ZX-E Operation Manual

Precautions for Safe Use

Always observe the following precautions to ensure safety.
Environment
• Do not use the Smart Sensor in locations subject to explosive or flammable gases.
• To ensure safety in operation and maintenance, do not install the Smart Sensor near
high-voltage equipment or power devices.
Power Supply and Wiring
• Do not impose voltages exceeding the rated voltage (12 to 24 VDC ± 10%).
• When supplying power to the Sensor, make sure that the polarity of the power is cor-
rect, and do not connect to an AC power supply.
• Do not short-circuit the load for the open collector output.
• Do not lay the power supply cable for the Smart Sensor together with high-voltage
lines or power lines. Doing so, or placing them into the same duct, can cause induc-
tion and lead to malfunction or damage.
• Always turn OFF the power supply before wiring and before connecting or disconnect-
ing connectors.
Settings
• When setting the threshold value with the Smart Sensor connected to an external
device, turn ON the Amplifier Unit's judgement output hold input to prevent the
judgement from being output to the external device.
Others
• The ZX-L-series Smart Sensors (Laser Type), ZX-W-series Smart Sensors (Micro-
wave Type), and ZX-T-series Smart Sensors (High-precision Contact Type) are not
compatible. Do not use ZX-L-series, ZX-W-series, or ZX-T-series Smart Sensors
together with ZX-E-series Smart Sensors.
• Do not attempt to disassemble, repair, or modify the Smart Sensor.
• When disposing of the Smart Sensor, treat it as industrial waste.
