At the customer’s request, OMRON will provide applicable third party certification documents identifying
ratings and limitations of use that apply to the products. This information by itself is not sufficient for a
complete determination of the suitability of the products in combination with the end product, machine,
system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not
intended to be an exhaustive list of all possible uses of the products, nor is it intended to imply that the uses
listed may be suitable for the products:
• Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or
uses not described in this document.
• Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical
equipment, amusement machines, vehicles, safety equipment, and installations subject to separate
industry or government regulations.
• Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR

FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
Please observe the following precautions for safe use of the product:
1) Do not use the product in environments where it can be exposed to inflammable/explosive gas.
2) Do not use this product in locations where it will be sprayed by water, oil or chemical fumes, or in steamy locations.
3) Do not attempt to dismantle, repair, or modify the product.
4) The supply voltage and current must be within the rated ranges.
5) Do not wire the product incorrectly (e.g. mistake the polarity of the power supply, or mistake wiring terminals).
6) Correctly connect the load to both control and analog outputs.
7) Both ends of the load on control outputs and analog outputs should not be short-circuited.
8) Do not use the product with the case damaged.
9) Dispose of this product as industrial waste.
1) Electrical lines and power lines must be wired separately from this product. Wiring them together or placing them in the
same duct may cause induction, resulting in malfunction or damage.
2) Limit cable extensions to 10 m. Use extension cable of 0.3 mm2in diameter or thicker.
3) Sensing is possible 200 ms after the product is turned on.
When the load and product are powered by different power supplies, be sure to turn the product on before the load.
4) Be sure to use the product with its protective cover attached.
5) When a write error occurs (ERR/EEP flashes) due to power being cut off, or static electricity or other noise, initialize the
product settings by its setting keys.
6) After the product is turned on, it sometimes takes time for the displayed distance value to stabilize in some operating
environments.
7) An output pulse is sometimes generated when the product power is cut. For this reason, cut the power of the load or
load line before turning the product off.
8) Do not use paint thinner, benzene, acetone, or kerosene for cleaning.
9) Before connecting or disconnecting connectors to the Sensor Head, be sure to turn the product off.
Only the E4C Sensor Head can be used. Other Sensor Heads cannot be used. Use of a different model of Sensor
Head may damage the product.
10)The distance value displayed in the amplifier's display is different from the value measured using a tape measure or
other apparatuses. When the value must be adjusted for use, adjust the value using the scaling function.

Switching Modes
To switch the operating mode, use the SET/RUN Switch.
Switch to the desired mode before operating the Amplifier Unit.
Key Operations
Use the Control Keys to change the display and set sensing conditions.
The currently selected mode determines the key functions.
About key pressing time
Unless otherwise mentioned in text descriptions, press keys for about one second.
Example: Press the UP key.
This means that you hold down the key for about one second and then release the key.
Reading Displays
The data displayed on the main and sub-displays depends on the currently selected mode. When the power is first turned
ON after shipment, RUN mode data is displayed.
* Display details can be changed by the display switch function. Refer to "Function Transition Charts" in "5. Function
Overview."
Installing the Amplifier Unit
JInstallation procedure
Hook the Sensor Head connector end of the Amplifier Unit on the
DIN Track and press in at the bottom until the Amplifier Unit locks

Initial setting of the head type
Set the head type when the power is first turned ON after the Amplifier Unit is purchased.
JSetting procedure
When the power is first turned ON, the following is displayed.
Note: The head type does not need to be set from the second time that the power is turned ON.
Changing the head type
This feature is used to display the type of head to connect the
Amplifier Unit to.
Switch the SET/RUN switch to SET and change the head type by
following the procedure below.
JChange procedure
Select whether to turn output ON when the distance between workpiece and the Sensor Head is shorter than the threshold
value (near distance) or when it is longer than the threshold value (far distance).
• The setting method varies depending on the Amplifier Unit model.
6. Basic Settings
1. Setting the Head Type
2. Setting the Operating Mode
Selection Details
NON (near ON)
(default)
Output turns ON when the distance between the workpiece and the Sensor Head is shorter than the threshold value.
FON (far ON) Output turns ON when the distance between the workpiece and the Sensor Head is longer than the threshold value.

1) Teaching settings
(1) Teaching with and without a workpiece
Set two points one with a workpiece and another without a workpiece to be respectively sensed, and set the point between
these two points as the threshold value. This setting can be made in both of the RUN and SET modes.
When this setting is made in the RUN mode, make sure that the "MODE key setting" function is set to [2PNT]. The default
setting is [2PNT]. Refer to "Function Transition Charts" in "5. Function Overview."
(2) Teaching without a workpiece (background teaching)
Set the threshold value referenced to a state in which a workpiece is not present (background).
Set the threshold value 10% in front the sensing range width referenced to the distance in a workpiece absent state.
Example: In the case of a 50 to 300 mm type, set the threshold value about 25 mm in front.

(3) Automatic-teaching (set by a moving workpiece)
Measure the sensing distance while the key is held down, and set the value between the minimum and maximum distance
values as the threshold value.
Before making this setting, make sure that the MODE key setting is set to [AUTO]. The default setting is [2PNT]. Refer to
"Function Transition Charts" in "5. Function Overview."
(4) Position teaching
Set the sensing distance of the workpiece as the threshold value.
Before making this setting, make sure that the MODE key setting is set to [PPT]. The default setting is [2PNT]. Refer to
"Function Transition Charts" in "5. Function Overview."
• Teaching error display
An error occurs if the following is displayed on the sub-display after teaching is executed.
Execute teaching again.
OVER error
The taught distance is outside the sensing range.
Check the position of the workpiece, and then execute teaching again.
NEAR error
The difference between the maximum taught distance and the minimum
taught distance is too small.
Check the teaching position, and then execute teaching again.
(This error occurs with teaching with and without a workpiece, and
automatic-teaching.)

Before making this setting, make sure that the "MODE key setting" is set to [0RST] (zero reset).
The default setting is [2PNT] (teaching with and without a workpiece). (Refer to "Function Transition Charts" in "5. Function
Overview.")
Setting the Display to Any Value (offset)
Before making this setting, make sure that the "MODE key setting" is set to [oFST] (offset).
The default setting is [2PNT] (teaching with and without a workpiece). (Refer to "Function Transition Charts" in "5. Function
Overview.")
Inverting the Increment/decrement Direction of the Main Display (display inversion)
When display inversion is executed, how the display to the reference distance is indicated is inverted.
Before making this setting, make sure that the MODE key setting is set to [0RST] (zero reset) or [oFST] (offset).
