Status
Cause
Countermeasure
The unit does not operate at all
(1) The power is not turned on (including disconnection), or
the power voltage is too low
(2) There are materials blocking the front of the sensor
(3) The sensitivity setting is too low
(1) Check the power cable, and set the appropriate power
voltage
(2) Remove the blocking materials
(3) Set the appropriate sensitivity (Refer to “8. Function
Description”)
The unit remains in check mode,
not switching to operation mode
(1) There are noise sources (bells, ultrasonic sensors,
printers, or devices that generate metallic sound) near
the unit
(1) Remove items causing malfunction, or keep them apart
from the unit (three meters or more)
The unit sometimes does not
operate
(1) The sensitivity setting is too low
(2) The distance between the unit and glass surface to be
detected is inappropriate
(1) Set the appropriate sensitivity (Refer to “8. Function
Description”)
(2) Set the detection distance within the rated value
The unit suddenly operates when
nothing has occurred
(1) The power voltage becomes unstable
(2) There are noise sources (bells, ultrasonic sensors,
printers, or devices that generate metallic sound) near
the unit
(3) There are sources that generate electric noise near the
unit
(4) The sensitivity setting is too high
(1) Set the appropriate power voltage
(2) Remove items causing malfunction, or keep them apart
from the unit (three meters or more)
(3) Change the installation place, or remove items causing
malfunction
(4) Set the appropriate sensitivity (Refer to “8. Function
Description”)
The alarm indicator lights up, but
connecting devices do not operate
(1) Connection failure occurs on alarm signal, and wiring is
disconnected or short-circuited
(2) The alarm contact output is generated
(3) The alarm output setting is inappropriate
(4) Connected devices do not operate properly
(1) Fix connection failure, disconnection/short circuit
(2) Check the output terminal section using testers
(3) Change the alarm output setting
(4) Check connected devices
Daily inspection
•
For maintenance, after wiping the unit with a moistened soft cloth, dry it off.
If the unit is very dirty, gently wipe using a soft cloth immersed in diluted neutral detergent, wiping off any detergent residue
thoroughly afterwards.
Do not use thinner or benzine. (Failure to do so may result in the deformation of discoloration or deterioration of plastic parts)
•
Periodically check operation, approximately once a week.
In addition, make sure to check operation when desks or partitions have been moved due to layout change in the room to be
protected.
