UPPER/LOWER CHANGEOVER FUNCTION
This function allows you to switch the optical unit to transmit/receive the light by pressing the upper/lower changeover switch.
Note: The sensors switch as shown in the diagram below when the upper/lower changeover switch is pressed.

LIGHT SENSITIVITY SIGNAL FUNCTION
The LED lights up when the light reception level is considered to be insufficient
in order to notify the operator of that an inspection is necessary.
8-5
EXTERNAL ENVIRONMENT DIAGNOSTIC FUNCTION
Note: Only installed on the receiver
The light reception level falls below the specified level under adverse environmental conditions such as dense fog or heavy rain.
This function issues an environmental output if such conditions are maintained.
Note: The environmental output continues until the light reception level for both the upper and lower beams recovers to the
specified level (for 5 seconds at the shortest).

ALIGNMENT WIRELESS CHECKER CONNECTION FUNCTION
Note: Installed on the transmitter and the receiver
Using the alignment wireless checker that is sold separately enables easy and accurate optical axis adjustment.
Providing sufficient margin of sensitivity increases the resistance to the dense fog, snow, and heavy rain, which makes it possible
to construct a highly reliable intrusion alert system.

TROUBLESHOOTING
Status
Transmitter LED does not
light (cover is open)
Alarm LED does not light
even if the photoelectric
beam is obstructed
Alarm LED does not go out
(Alarm output does not stop)
Continually activated
To clean the device, use a soft, wet cloth and then wipe off any water drops.
Daily Inspections
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.

• 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.
Cause
(1) Power is not on
(2) Poor wiring or breaking of wire, short
(3) Transmitter is set to [Do not transmit]
(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
(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

Remedy
(1) Connect the power source
(2) Check again
(3) Press the upper/lower changeover switch
(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) Perform angle adjustment again
(2) Remove the object
(3) Clean using a soft cloth
(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,
(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)
