(1) Power is not on
(2) Poor wiring or breaking of wire, short
(3) Transmitter is set to [Do not transmit]
(1) Connect the power source
(2) Check again
(3) Press the upper/lower changeover switch
(1) Power is not on
(2) Poor wiring or breaking of wire, short
(1) Connect the power source
(2) Check again
(1) Connect the power source
(2) Check again
(3) Remove the reflecting object, or change
the installation location or optical axis
direction
(4) Obstruct four levels simultaneously
(5) Shorten the detection response time
(1) Power is not on
(2) Poor wiring or breaking of wire, short
(3) Photoelectric beam is reflected by some object and
entering the receiver
(4) Four levels are not obstructed simultaneously
(5) Sensor beam is obstructed for less time than the
detection response time setting in the receiver
(1) Optical axis (alignment) is not aligned correctly
(2) There is an obstruction between the transmitter and
receiver
(3) Transmitter/receiver cover or reflection section is dirty
(4) Frequency channel settings on the transmitter and
receiver do not match
(1) Poor wiring connection
(2) Change of supply voltage
(3) Obstruction between transmitter and receiver (objects
such as branches that move with the wind)
(4) The wiring of the transmitter/receiver is located nearby
a power line
(5) Unstable sensor installation
(6) Transmitter/receiver cover or reflection section is dirty
(7) Improper alignment of optical axis
(8) A large bird or cat may obstruct the beams
(9) Transmission power switch is set to L, which does not
keep enough margin of sensitivity
(1) Check again
(2) Stabilize the supply voltage
(3) Remove the object
(4) Change the wiring route
(5) Fix in a stable location
(6) Clean using a soft cloth
(7) Perform optical axis adjustment again, set
the gain lock and secure the margin of
sensitivity
(8) Set the response time to be slightly longer
(however, this is not possible if there is a
possibility that an intruder could run
through at top speed)
(9) Set the transmission power switch to H,
remove the receiver cover and set the gain
lock again
(1) Perform angle adjustment again and set
the gain lock
(2) Remove the object
(3) Clean using a soft cloth
(4) Readjust the frequency channels so they
are the same

Alarm LED does not light
even if the photoelectric
beam is obstructed
• Check the device by referring to the table below. If you cannot restore the device to a
normal condition after the check, contact the place of purchase or TAKEX.
To clean the device, use a soft, wet cloth and then wipe off any water drops.
If the device is particularly dirty, dip the soft cloth in water that includes a weak neutral detergent.
Wipe the device gently with the cloth, then wipe off any detergent that remains.
Do not use substances such as thinner or benzene. (The plastic parts may deform, discolor or change their properties.)
Perform operation checks on a regular weekly basis.
