D.7.2) Sensor symptoms using wrong Door Mode settings

Mode
Folding Door Setting
Type
Folding Door ○ Normal Operation
No activating signal at fully
Sliding Door closed position, thus no
opening door.

Measures
Check Wiring Cable and Connector
Rated Voltage for This Sensor is 12～24V AC/DC.
apply voltages other than the rated voltages. Use Class 2 power
supply.
Wipe off the stain with neutral detergent applied soft cloth. (Do
not use such chemicals as Thinner or Alcohol, etc.)
Set higher sensitivity
Make readjustments with Area Setting Switches, Area Setting
Lever, Area Fine Adjustment Mechanism
Lower Sensitivity at the Setting Switch.
Set the different Interference Prevention Modes by setting
switches.
Check to ensure Detection Area is tilted toward Door panel.
Readjust the Detecting Area to avoid objects or remove the ob-
ject(s) to outside the Detection Area.
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.
Detection is made by Door Detector. Lower the sensitivity.
(Example: SW4=OFF, SW5=ON )
Detection is made by Door Detector. Lower the sensitivity.
( Example: SW4=OFF, SW5=ON )
The sensor does not recognize the movement of Door. Readjust
the area toward Door side by Area Fine Adjustment Mechanism.
Self-Diagnosis Function Determines the unit Out of Order.
After turning power on, allow up to 3 minutes without anyone
entering the detection pattern for the sensor to stabilize.
