Power Supplies; Power Supply - Omron ZX-E Datasheet

Precautions
■ Design Precautions
Conform to the specified ratings and performance. Refer to Specifi-
cations on page 2 for details.
Objects of certain materials or shapes may not be detectable, or the
detection accuracy may not be sufficiently high.
Environment
Do not operate the product in locations subject to flammable or explo-
sive gases.
In order to ensure safe operation and maintenance, do not install the
product in the vicinity of high-voltage devices or power equipment.
■ Wiring
Do not use the product at voltages exceeding the rated values. Doing
so may result in damage.
Do not connect the product to an AC power supply or connect the
power supply in reverse.
Do not short-circuit the load for open-collector output.
■ Correct Use
Design Precautions

Power Supplies

Allow a warm-up period of approximately 30 minutes after turning ON
the power supply.
Mutual Interference
Up to 5 Sensor Heads can be used together by connecting the ZX-
CAL2 Calculating Unit between Amplifier Units.
When installing Sensor Heads facing each other or in parallel, sepa-
rate them by the minimum distances given in the table below.

ence prevention function is used.
Compatibility
Sensors and Amplifier Units are mutually compatible. Sensors can be
added or replaced individually.
Influence of High-frequency
Electromagnetic Fields
Using the product in the vicinity of devices that generate high-fre-
quency electromagnetic fields, such as ultrasonic cleaning equip-
ment, high-frequency generators, transceivers, mobile phones, and
inverters, may result in malfunction.

ZX-E Series
Do not lay the power cable for the product together with or in the same
duct as high-voltage lines or power lines. Doing so may result in in-
correct operation or damage due to induction.
Do not connect or disconnect connectors while the power is ON. Do-
ing so may result in damage.
■ Adjustment
Setting
When setting threshold values, ensure that the Amplifier Unit's judge-
ment output hold input line is ON so that there is no judgement output
to external devices.
■ Other Precautions
Do not attempt to disassemble, repair, or modify the product.
Dispose of the product using standard procedures for industrial
waste.
These Sensors are not compatible with the ZX-L@@ Smart Sensors
(laser type). Do not connect combinations of ZX-E@@ Smart Sensors
and ZX-T@@ Smart Sensors.
Influence of Metallic Objects
When installing the product, separate it from metallic objects by the
distances shown below.

Wiring
Wiring Check
After wiring is completed, before turning ON the power, confirm that
the power supply is connected correctly, that there are no faulty con-
nections, such as load short-circuits, and that the load current is cor-
rect. Incorrect wiring may result in failure.
Cable Extension
Do not extend the cable for the Sensor and the Amplifier Unit to a
length exceeding 10 m. Use a ZX-XC@A Extension Cable (sold sep-
arately) to extend the Sensor's cable. Extend the Amplifier Unit's ca-
ble using a shielded cable of the same type.

Power Supply

When using a commercially available switching regulator, ground the
FG (frame ground) terminal.
If the power supply line is subject to surges, connect a surge absorber
that meets the conditions of the operating environment.
