11 TROUBLE SHOOTING GUIDE
Possible cause A Remedy
Indication lamp of Transmitter
does not light. Improper voltage of power supply Check power supply and wiring
Power supply indication Lamp
of Receiver does not light. Improper voltage of power supply Check power supply and wiring
Alarm indication lamp does not
light even when the beams are
intercepted.
Remove the reflecting object or change the place
for installation and the optical axis direction.
Check three beams to intercept at the same time.
Adjust obscuration time setting to be shorter.
Melted bridge on the signal connection
Check the wiring.
It needs to be repaired.
Alarm LED on the Receiver
does not turn off.
Inadequate optical axis.
Shading objects between the Transmitter and
the Receiver.
Readjust the optical axis.
Remove the shading objects.
Clean optics with soft cloth.
Bad wiring connection.
Change of supply voltage.
Shading objects moving by wind between the
Transitter and the Receiver.
Unstable installation of the sensor unit.
Incomplete optical axis adjustment.
Birds and other large flying objects intercept the
beam.
Check the wiring connection.
Check the voltage (for stabilized supply voltage.)
Remove the shading objects or change the place
for installation.
Fix steadily.
Readjust the optical axis.
Readjust the obscuration time to be longer or
reposition.
Infrared beam from Transmitter is reflected on
another object and sent into the Receiver.
Shorter obscuration time than that set on the
obscuration control.
Q Symptom
Intermittent alarm.
Although alarm LED lights
intercepted, alarm does
when the beams are
not ring.
Three beams are not intercepted at the same time.
Broken wires or short on the signal wires.
(Wrong current on the signal wires)
Dirty cover or dirty reflection mirror of the
Transmitter and/or Receiver.

ADJUSTMENT OF OBSCURATION
Caution: Obscuration time settings exceeding 70msec (exceeding a setting of 1)
do not comply with the requirements in
UL639. Instrusion Detection Units.
Set the obscuration time of the receiver by adjusting the obscuration time
control to the required setting according to the sketch (8-1). The obscuration
time should be set lower to detect faster moving targets, however care should
be taken to note the environmental conditions as the obscuration time should
be set higher to ignore conditions where there are a lot of birds or wind
blown material.
Obscuration time control
fast running at full speed (6.9m/s)
walking with quick steps (1.2m/s)
normal walking (0.7m/s)
slow action (0.3 0.5m/s)

Look through the viewfinder(7-3) as shown below.
ADJUSTMENT OF OPTICAL AXIS
(7-1)
Turn on the power supply after uninstallation.
(7-8)
Adjust the angle of the lens via the Horizontal angle adjustment and
the Vertical adjustment(7-5) screw so that the sensor can be seen in
the center of the Viewfinder.This adjustment is carried out on both
the Transmitter and Receiver. Confirm after adjustment that the
green GOOD LED is on, otherwise alignment should be readjusted.
The red LEVEL LED lamp will be brighter dependent on higher signal
levels.
It is important to ensure correct optical alignment
between the transmitter and receiver for proper
operation.
(7-4) Place the viewfinder(7-3) on either right or left hand side of the lens
whichever makes easier viewing.
NOTE:After completion of optical adjustment, ensure that both filters on the
receiver are replaced t o their original position behind t he mirrors.
(7-11)
Insert the meter pins into the monitor jack(7-9). (Pay attention to the
polarity because of DC voltage)
(7-10)
The best adjustment of optical axis can be done by reading the output
voltage of the monitor jack.
NOTE: If the sensors are too close together then the signal level saturates
and the IR beam may be shut-down. This is normal and will only be
achieved during bench testing. Signal levels are restored u nder
normal operation distances.
(7-12)
a) Adjust the horizontal adjustment until the output is at a maximum.
b) Adjust the vertical adjustment screw to obtain best signal.
(Do not interrupt beam by hands during the adjustment)
(7-13)
The following minimum voltages should be obtained to ensure best
performance.2.3V for all of the SBM series. If this is not obtained
then the transmitter and receiver should be re-aligned.

SUGGESTIONS FOR
INSTALLATION
Ensure the sensors line of sight is free from any false
alarm sources such as bushes, trees,etc.
(Pay attention to these as they may change seasonally.)
Ensure the sensors are mounted on a stable and firm
fixing.
Ensure strong sunlight or car headlights do not shine
directly on to the receiver. (Within 2 from the optical
axis is not recommended.)
In case of jump phenomenon, as shown section(3-5),
change the disposition of transmitter and receiver to the
following m anner s hown s ection(3-10).
