Safety precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the product in atmospheres or environmets that exceed
product ratings.
• Separate the Sensor wiring from power supply and high-voltage
lines. If Sensor wiring is placed together with or in the same duct
as power supply or high-voltage lines, inductance may cause
malfunction or damage to the Sensor.
• The extended cable length must be no more than 10 m. To extend
the cable length, use 0.3 mm2 cable.
• Detection will be possible 200 ms or longer after the power supply
is turned ON. If separate power supplies are used for the load and
the Sensor, turn ON the power supply to the Sensor first.
• Make sure that the cover to the Amplifier is in place before using
the Sensor.
• If a writing error occurs (ERR/EEP will flash on the display) due to
noise resulting from turning OFF the power supply, static
electricity, or other cause, initialize the settings using the SET
switch on the Amplifier.
• Depending on the application environment, some time may be
required for the displayed distance to stabilize after turning ON the
power supply.
• Output pulses may be generated when the power supply to the
Amplifier is turned OFF. Turn OFF the load or the power supply to
the load before turning OFF the Sensor.
• Do not use thinners, benzine, acetone, kerosene, or any other
petroleum solvents to clean the Sensor or Amplifier.
• Turn OFF the power supply before connecting or disconnecting the
Sensor Head.
Use only an E4C Sensor Head. The product may be damaged if
any other Sensor Head is connected.
• The distance displayed on the Amplifier may be different from
values obtained with tape measures or other devices.
To adjust the displayed distance, use the scaling function.
Mutual Interference
When installing two or more Sensor Heads side by side, ensure that
the minimum distances given in the following table are maintained.

* These distances are the separations at the maximum
measurement distances. The degree of effect depends on the
equipment and surrounding conditions. Check the degree of
effect after you install the Sensor Heads in your operating
environment.
