Adjustment Methods
1. Setting the Operation Mode
The operation mode is set in SET mode. Refer to page A-373 5. Set-
ting Functions in SET Mode.
Set the Channel Selector to the desired channel before making any
adjustments or settings. This is true for all adjustments and settings.
2. Adjusting the Power (RUN Mode)
The current incident light level can be adjusted to near the power
tuning target value (default: 2,000).
Confirm that the MODE key setting is PTUN (power tuning). The
default setting is PTUN. Refer to page A-373 5. Setting Functions in
SET Mode
* Setting Errors
An error has occurred if one of the following displays appears after
the progress bar is displayed.
Note: Press the DOWN key right after pressing the MODE key.
3.Setting Thresholds Manually
(RUN Mode)
A threshold can be set manually. A threshold value can also be fine-
tuned using manual setting after teaching.
* Even if the display method for display switching is changed, the
threshold will appear on the sub-display when the key is pressed.
4. Teaching the Threshold Value (SET Mode)
* There are four methods that can be used for teaching, as described
below. Use the method most suitable for the application.
* An error has occurred if OVER, LO, or NEAR is displayed on the
sub-display. Repeat the operation from the beginning.
4-1. Setting the Threshold at Maximum Sensitivity
The threshold can be set at the maximum sensitivity. This method is
ideal when using a Through-beam Fiber Unit to detect workpieces so
that detection is not influenced to any great degree by dust and other
environmental factors.
