Precautions for Safe Use
Please observe the following precautions for safe use of the product.
1)Do not use the Amplifier Unit in environments subject to flammable or explosive gases.
2)Do not use the Amplifier Unit in environments subject to exposure to water, oil, chemicals, etc.
3)Do not attempt to disassemble, repair, or modify the Amplifier Unit in any way.
4)Do not apply voltages or currents that exceed the rated ranges.
5)Wire the Amplifier Unit correctly, e.g., do not reverse the polarity of the power supply.
6)Connect the load correctly.
7)Do not short both ends of the load.
8)Do not use the Amplifier Unit if the case is damaged.
9)When disposing of the Amplifier Unit, treat it as industrial waste.
Precautions for Correct Use
Please observe the following precautions to prevent failure to operate, malfunction, or undesiable effects on
product performance.
1)The optical fibers are made out of methacrylic resin. Do not use them in atmospheres where organic solvents
are present.
2)Wire the Amplifier Unit separately from power supply or high-voltage lines. If the Amplifier Unit wiring is wired
together with or placed in the same duct as high-power lines, inductive noise may cause operating errors or
damage the Amplifier Unit.
2
3) Do not extend the cable to more than 100 m, and use a wire size of 0.3 mm or larger for the extension cable.
4)The Amplifier Unit is ready to operate 200 ms after the power supply is turned ON. If the Amplifier Unit and load
are connected to power supplies separately, turn ON the power supply to the Amplifier Unit first.
5)Always keep the protective cover in place when using the Amplifier Unit.
6)Connector Short-circuit Protection (for Amplifier Units with Connectors)
To prevent electric shock or short-circuits, attach the protector seals provided
with E3X-CN-series Connectors to the sides of power supply connectors
that are not being used.
7)Always turn OFF the power supply before connecting, separating, or
adding Amplifier Units.
8)If the data is not written to the EEPROM correctly due to a power failure or
static-electric noise, initialize the settings using the keys on the Amplifier
Unit.
Power supply
9) Using a Mobile Console
connector
Use the E3X-MC11-SV2 Mobile Console for the E3X-DA-S series Amplifier
Units. However, there is a function which cannot be used in part. Other
Mobile Consoles, such as the E3X-MC11, cannot be used.
10) Optical communications are not possible with an E3X-DA-N Amplifier Unit.
11) Depending on the application environment, time may be required for the incident light level to stabilize after
the power supply is turned ON.
12) Do not use thinners, benzine, acetone, or kerosene for cleaning the Amplifier Unit.
13) Do not pull or apply excessive pressure or force (exceeding 9.8 N ・ m) on the Fiber Unit when it is mounted to
the Amplifier Unit.
14) Output pulses may occur when the power is interrupted and so turn OFF the power to the load or load line
before turning OFF the power to the Sensor.

2. Adjusting the Power (as Required)
Power tuning can be used to adjust the incident light level that is currently being received to the power
tuning target value (default: 2,000). Before tuning ON the power, always secure the detection object and
Head and be sure that the incident light level is stable.

If the output setting is set to 1-2 (differential operation), the value between the two
differential values when teaching is performed is used as the threshold setting.

③Teaching for Through-beam Sensor Heads
Teaching for a Through-beam Sensor Head is performed without a workpiece. A value
about 6% less than the incident light level with no workpiece is set as the threshold value.
This method is ideal to stably detect very small differences in light level.

④ Teaching for Reflective Sensor Heads
Teaching for a Reflective Sensor Head is performed without a workpiece (i.e., for the
background). A value about 6% greater than the incident light level is set as the threshold
value. This method is ideal to stably detect very small differences in light level.
