Safety Precautions
E3X-DA-S
To ensure safe operation, be sure to read and follow the Instruction Manual provided with the sensor.
WARNING
Precautions for Correct Use
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
CAUTION
Do not use the sensor with voltage in excess of the
rated voltage. Excess voltage may result in
malfunction or fire.
Never use the sensor with an AC power supply.
Otherwise, explosion may result.
Do not use the product in atmospheres or environments that exceed
product ratings.

Operation after Turning Power ON
The sensor is ready to detect within 200 ms after the power supply is
turned ON. If the sensor and load are connected to separate power
supplies, be sure to turn ON the sensor first.
Time may be required for the incident level to stabilize after the power
supply is turned ON.
Operation at Power OFF
A pulse may be output when the power supply is turned OFF. Turn
OFF the power supply to the load or the load line before turning OFF
the power supply to the sensor.
Precautions for Safe Use
The following precautions must be observed to ensure safe operation
of the sensor.
1. Do not use the sensor in an environment where explosive or
flammable gas is present.
2. Do not use the sensor in a location subject to splattering with
water, streams, oils, or chemicals.
3. Do not attempt to disassemble, repair, or modify the sensor.
4. Do not apply voltages or currents that exceed the rated range to
the sensor.
5. Do not use the sensor in an ambient atmosphere or environment
that exceeds the ratings.
6. Wire the power supply correctly, including the polarity.
7. Connect the load correctly.
8. Do not short-circuit the load at both ends.
9. Do not use the sensor if the case is damaged.
10.Dispose of the sensor as industrial waste.
11.Do not use the sensor in locations subject to direct sunlight.
Mutual Interference Protection Function
Mutual interference prevention is enabled if Amplifier Units are
connected together. It is also enabled in the same way if E3X-DA-S-
series Units and E3C-LDA-series Units are used together.
Mounting
Connecting and Disconnecting Connectors
Mounting Connectors
1. Insert the Master or Slave connector into the Amplifier Unit until it
clicks into place.
Insert
2. Attach the protective seals (provided as accessories) to the sides
of master and slave connectors that are not connected.
Seal
Note: Attach the seals to the sides with grooves.
Removing Connectors
1. Slide the slave Amplifier Unit away from the other unit.
2. After the Amplifier Unit has been separated, press down on the
lever on the connector and remove it. (Do not attempt to remove a
connector without first separating the Amplifier Unit from the other
Units.)
