Advanced Photoelectric Sensors
Basic Operating Information
Setting the Mode
The mode is set using the SET/RUN switch. Set this switch according to the operation to be performed.
Key Operations
The operation keys are used to switch the displays and set detection conditions. The functions of the keys depend on the current
mode.
Time to Press Keys
If a specific time for pressing a key is not given in a procedure, press the key for approximately 1 second.
For example, if the procedure says “press the UP key,” then press the UP key for approximately 1 second
and then release it.
Reading Displays
The information displayed on the main display and sub-display depends on the current mode.
For the default settings, the RUN mode displays will appear when the power supply is turned ON for the first time
Note:
The information that appears on the displays can be set using the display switch function. Refer to Detailed Settings.
Basic Settings
Setting the Operation Mode
Select either light-ON or dark-ON operation.
The setting method depends on the type of Amplifier Unit.

Mode
Description
SET
Select to set detection conditions, to teach the threshold value, etc.
RUN
Select for actual detection operation or to set the following: Manual adjust-
ment of thresholds, power adjustment, zero reset, or key lock.
Key
Function
RUN mode
SET mode
UP key
Increases the threshold.
Depends on the setting.
−
Executes teaching.
−
Changes the setting forward.
DOWN
key
Decreases the threshold.
Depends on the setting.
−
Executes teaching.
−
Changes the setting in reverse.
MODE key
Depends on the MODE key setting.
−
Executes power tuning (default set-
ting).

Executes a zero reset.
Switches the function to be set on the
display.
Mode
Main display (red)
Sub-display (green)
Set
Displays the incident light level,* function name, or
other information depending on the key operation.
*The incident light level will be displayed even if
DIFF (differential operation) is set for the detection
method.
Displays threshold value* or the setting of the func-
tion displayed on the main display depending on the
key operation.
*The threshold value for the change in the incident
light level will be displayed if DIFF (differential oper-
ation) is set for the detection method.
RUN
(See
note.)
For the default setting, the current incident light level
will be displayed.
The change in the incident light level will be dis-
played when DIFF (differential operation) is set for
the detection mode.
For the default setting, the current threshold value
will be displayed.
The threshold value for the change in the incident
light level will be displayed if DIFF (differential oper-
ation) is set for the detection method.
Selection
Description
LON (light-ON)
(default)
The output will turn ON when the incident light level is above the threshold.
If DIFF (differential operation) is set for the detection method, the output will turn ON when an edge is detected.
DON (dark-ON)
The output will turn ON when the incident light level is below the threshold.
If DIFF (differential operation) is set for the detection method, the output will turn OFF when an edge is detected.
Type
Setting method
Twin-output model
Set as the operation mode in SET mode.
Refer to 5. Detailed Settings.
External-input
model
Set using the operation mode selector.
