4-2 OPERATION CHECK

Conduct a walk to check that the alarm indicator LED on the receiver turns ON or the beep sound rings
on the receiver as the walker interrupts the beam.
Be sure to conduct a walk test (to block the infrared beam) at the following three points:
In front of the transmitter
A
In front of the receiver
B
At the middle point between the transmitter and the receiver
C
The detector is installed properly when the Alarm indicator LED turns ON and the
beep sound rings in the tests at all three points.
Note>>
Conduct a walk test at least once a year.
receiver are pressed (the covers are closed).

TROUBLESHOOTING

5-1 TROUBLESHOOTING
PROBLEM
LEDs are not illuminated
(Transmitter/receiver)
"ALARM" LED is not illuminated
even if the beam is blocked
Blocking the beam, and
illuminates "ALARM" LED but
does not active the alarm.
Alignment level indicator LEDs are
not illuminated (Transmitter/
Receiver)
Alignment level indicator LEDs of
only the Transmitter are not
illuminated.
Alarm is activated even if the beam
is not blocked
Frost, snow or heavy rain causes
false alarm.
Improper output
POSSIBLE CAUSE
Inappropriate power voltage
Inappropriate wiring distance or wire diameter
Power supply selector setting is incorrect.
Beam has not been blocked.
Signal line short-circuited
Alarm contact welded
Optical alignment is not optimized.
The channel setting between the Transmitter
and the Receiver does not match.
Inappropriate optical alignment for the upper
beam unit.
Interruption time is too short
Surface of the transmitter/receiver cover soiled
Channels of the transmitter and receiver are different
Multiple photoelectric detector for long
distance or beam stacking applications.
Optical alignment was not performed properly
Optical alignment is not optimized
The wiring is incorrect

CORRECTIVE ACTION
Check the voltage and make sure that it is
between 10.5 and 30 VDC
See "2-5 WIRING DISTANCE BETWEEN POWER
SUPPLY AND DETECTOR" on page 6,check the
wiring distance.
See "6-2 SOLAR BATTERY UNIT SBU-4 (OPTION)"
on page 18, check the power supply selector
setting: Normal (left), SBU-4 (right)
See"4-1 OPTICAL ALIGNMENT" on Page 15 and
make realignment. If the problem persist,
see "BEAM POWER CONTROL SELECTOR"
on Page 13 and step down the beam power.
Block all four beams at same time
Check the wiring.
Repair is required. Contact the distributor or us.
See "4-1 OPTICAL ALIGNMENT" on Page 15 and
make realignment.
See "3-3 1 4 CHANNEL BEAM FREQUENCY
SELECTOR" on Page 11 and set to the same channel.
See"4-1 OPTICAL ALIGNMENT" on Page 15 and
make realignment.
See "BEAM INTERRUPTION ADJUSTMENT"
on page 11, set an appropriate interruption time.
Clean the cover (wipe the cover with a soft cloth
dampened with water-diluted neutral detergent)
Set the same channel to both the transmitter and receiver.
Set channels 1-3 or 2-4 or 1-4.
See"4-1 OPTICAL ALIGNMENT" on Page 15 and
make realignment.
See"4-1 OPTICAL ALIGNMENT" on Page 15 and
make realignment.
Make correct wiring.
