・
Connector Defects
Check Wiring Cable and Connector
Abnormal Power Voltage
Rated Voltage for This Sensor is 12
～
24V AC/DC. Do not
apply voltages other than the rated voltages. Use Class 2 power
supply.
No
Detection
Sensor Lens is stained with
dirt, water, etc.
Wipe off the stain with neutral detergent applied soft cloth. (Do
not use such chemicals as Thinner or Alcohol, etc.)
Low Sensitivity
Set higher sensitivity
Wrong Detection Area Set-
ting
Make readjustments with Area Setting Switches, Area Setting
Lever, Area Fine Adjustment Mechanism
Mis-detection
High Sensitivity
Lower Sensitivity at the Setting Switch.
Detection Area Overlapped
by other Detecter(s)
Set the different Interference Prevention Modes by setting
switches.
Not Detecting Door
Check to ensure Detection Area is tilted toward Door panel.
Movable Object(s) placed in
Detection Area
Readjust the Detecting Area to avoid objects or remove the ob-
ject(s) to outside the Detection Area.
Conditions in Detection Ar-
ea altered
When conditions in Detection Area change, the Sensor keeps
on detecting as long as the time set for Presence Detection.
Shorten the Presence Detection Time at the setting switch.
Operation Display Red LED
Blinks Several Times at Ful-
ly Opened Position
Detection is made by Door Detector. Lower the sensitivity.
(Example: SW4=OFF, SW5=ON )
Operation Display Amber
LED Blinks Several Times
at Fully Open Position
Detection is made by Door Detector. Lower the sensitivity.
( Example: SW4=OFF, SW5=ON )
Operation Display Green LED Blinks
The sensor does not recognize the movement of Door. Readjust
the area toward Door side by Area Fine Adjustment Mechanism.
Operation Display Red LED Blinks
Self-Diagnosis Function Determines the unit Out of Order.
Standstill Memory Time (Learn Time) is
Short
After turning power on, allow up to 3 minutes without anyone
entering the detection pattern for the sensor to stabilize.
