●Detection Principle
●This sensor uses reflection of a microwave and ultrasonic to detect a vehicle.
(The higher the reflection, the easier the detection becomes.)
●The microwave sensor uses FMCW technology, it can detect the presence of a vehicle.
●The ultrasonic sensor detects a vehicle close to the sensor.
●The detection logic is shown below.
3-1 Detection Principle and Basic Operation of the Sensor
Ultrasonic Sensor
Detection Area
Microwave Sensor
Detection Area
If only a person enters into the detection area, the
relay signal output will not trigger even if the
ultrasonic sensor detects the person (except when
the sensitivity level is set to 5).
When a vehicle is present, the microwave sensor detects the
vehicle and the ultrasonic sensor is activated at the same
time (if the sensitivity level is configured at 5, the ultrasonic
sensor will be activated all the time).
Before Using the Product
3
When the vehicle leaves the detection area, the sensor will
change to a non-detection status.
If a vehicle is parked in the detection area, the sensor
will maintain the detection status.
The following cases may occur due to the sensor detection principles.
●If a pedestrian or an object is in the detection area after the Vehicle leaves, the sensor
will maintain the detection status even if the vehicle leaves the detection area.
The sensor may not change to (or less tend to become) non-detection status due to
a flag/banner, tall weeds, and/or snow.
●If one vehicle tailgates another vehicle very closely when entering the detection area,
they may be recognized as one vehicle.
NOTE

-5-
There are two (2) types of sensor installations. Choose one depending on the site conditions from the following.
The sensor will not work correctly unless the installation directions, height, and operation type are correct.
●Always install the sensor on the vertical pole that is mounted in or on the ground.
Installing a sensor on a tilted pole will result in a detection of the ground by the
ultrasonic sensor and correct operation is not ensured.
3-2 Sensor Installation Recommendations
NOTE
●If the pole is installed on a slope,
install the sensor higher or lower in
order to adjust the height of the set
detection range to 500mm(19.69in.)
from the ground. It may reduce the
detection capability compared to the
normal installation.

The following cases may occur due to the sensor's characteristics.
●The sensor may not work properly if it is installed in a location that does not meet the
installation conditions.
●The sensor may not work correctly if it is not installed as per the instructions in this
manual.
●Pedestrians, bicycles, or any large object entering the detection area may be
detected.
●Depending on the position and/or direction of vehicle approach, the distance to be
detected may become shorter or may not be detected.
●Performance of the sensor may be affected if :
●The sensor pole is not vertical from the ground
●The sensor surface is covered with ice, snow, or dirt.
●A sensor unit is frozen
●Heavy snowing conditions
●It is raining heavily
●Water splash is on a sensor
●An object generating ultrasonic wave such as vehicle horn, motorcycle's engine
sound, and air brake sound is approaching
●Do not install any moving object such as flags or banners in the sensor's detection
area. Remove any vegetation from the detection area, or reconfigure the detection
area to be smaller. Not following these steps may stop the sensor reverting back to
non-detection status or delay the change of status.
●Do not place an object such as a signboard close to the ultrasonic sensor's detection
area. Sometimes the sensor may not become non-detection status or it may take a
long time to become non-detection status after vehicle leaves.
●There should not be irregularity on the ground in the ultrasonic sensor's detection
area. Sometimes the sensor may not become non-detection status or it may take a
long time to become non-detection status after vehicle leaves.
●Do not use a fluorescent lamp around the detection area. It may prevent proper
operation of the sensor.
●A gate bar with a curtain may cause unstable detection of the sensor. In such a case,
detach or relocate the curtain where is does not affect the detection.
3-3 Sensor Detection Recommendations
●Shown below are vehicle conditions to be detected by the sensor.
Minimum ground clearance: 150mm(5.91in.) or more
●A vehicle is detected when it approaches the gate
with speed of 2 to 20 kph(1.24 to 12.43mph).

●Calibration function
This function records (memorizes) the background of the detection area without any pedestrians or vehicle
present.
This process makes the sensor detection capability higher and provides stable detection.
If any noticeable changes occur around the detection area (such as construction of a wall or fence), you must
perform the calibration again.
●How to Perform Calibration
[1] Verify that within the detection area there is no vehicle, pedestrian, or objects. If anything is present
remove them out of the detection area.
[2] Press and hold the Calibration button on the sensor unit for 2 seconds and verify that the operation
indicator is blinking blue slowly.
The operation indicator blinks for 10 seconds and blinks more quickly for 2 seconds.
The first 10 seconds are preparation of calibration. You must keep the detection area vacant during this period.
The calibration is performed during the 2 seconds quick blinking period.
If a vehicle or pedestrian enter the detection area during calibration, perform the calibration again.
If the ultrasonic sensor detects an object during calibration, the operation indicator blinks in red and blue
alternately, resulting in calibration error.
The error may be caused by the following. Remove the cause of the error and perform the calibration
again. If the problem is unsolved, refer to P.22 "Ultrasonic Maximum Range" to reduce the range.
●The ultrasonic sensor detects any pedestrian or moving object (e.g. sign, gate, and gate bar) around the
detection area or irregularity on the ground.
●The sensor is installed too low and detects the ground.
●The sensor pole is tilted and the sensor detects the ground.
●The sensor installation angle is not proper and the sensor detects a next vehicle or wall (fence).
●It may take more than 2 seconds for the calibration if the sensor detects a moving object.
●If the calibration does not complete, check if there is any pedestrian or moving object (e.g. flag, banner,
tall weed) around the detection area. Remove it, and calibrate again.
[3] When the calibration is complete, the operation indicator turns to a solid green.
●Cancelling Calibration
To cancel calibration, press and hold the Calibration button for 2 seconds again while the operation indicator
is slowly blinking for 10 seconds. (The operation indicator turns to a solid green)
It is not possible to cancel it while the indictor is blinking quickly. Perform the calibration again.
4-3 Calibration
1. Press the Calibration button.
2. Operation indicator blinks in blue.
For normal sensor operation, the calibration must be properly performed.
The following instructions must be observed.
●Perform this after every sensor installation.
●It must be performed without vehicle, pedestrians or any other moving objects in the
detection area.
●If a vehicle or pedestrian enters the detection area during the calibration,
perform the calibration again.
●If changes are made to the sensor installation height, direction, and/or Microwave
Maximum Range after the calibration, the calibration has to be performed again.

●Detection Area Check Function
This function allows you to visually check the detection area of the microwave and ultrasonic signal using the
operation indicator. It is possible to verify the correct angle and size of the detection area.
*This detection area check must be performed after calibration.
●How to Check Detection Area
[1] Pressing the Area Check button switches to the Detection Area Check Mode and the operation indicator
blinks green. (If it keeps blinking green (no detection) for more than 30 seconds, it will automatically
change back to the Normal Operation Mode.)
If there is a pedestrian or an object in the detection area, the operation indicator turns either yellow, purple, or
blinks red (the operation indicator color depends on the detection status of the microwave and ultrasonic
sensors).
If the indicator is not blinking green, remove the object to outside of the area until the indicator blinks green.
If the operation indicator is showing a yellow blink while there is no human or object in the detection area,
perform the calibration again.
If the operation indicator is blinking purple or red, refer to P.22 "5-5 Ultrasonic Maximum Range" to reduce
the range of the ultrasonic sensor.
[2] Stand at the center of the vehicle lane (see Figure [A]) and walk in the direction of vehicle access.
When the operation indicator turns from green blinking (non-detection) to red blinking (detecting), it is the
edge of the detection area. (Under the normal operation mode, the detection area by vehicle may be
smaller)
If the detection area is not as expected, adjust the sensor angle and/or range again.
*After the adjustment, perform calibration again.
4-4 Detection Area Check
1. Press the Area Check button.
2. Operation indicator blinks green
●Only the microwave sensor is detecting: Blinking yellow
●Only the ultrasonic sensor is detecting: Blinking purple
●Both the microwave and the ultrasonic are detecting: Blinking red

[3] Stand at the edge of the vehicle lane (see Figure [B]), walk along the border and verify that the operation
indicator keeps blinking green (not detecting).
If the operation indicator changes to

the adjustment, perform calibration again and start from [2].
[4] After verifying the detection area, press the Area Check button again.
It switches the mode back to Normal Operation Mode and the operation indicator turns a solid green.
*If it keeps blinking green (no detection) for more than 30 seconds, it will automatically change back to the
Normal Operation Mode.
After verifying the detection area, check the entire operation system using a vehicle.
For the operation check, verify the proper operation with a vehicle on the left side, center, and right side of the
lane.

●Unsuitable environmental notification
In rare cases presence of a large metal object (i.e. a shutter) in the front of the sensor, the microwave
performance may be affected and the sensor operation may become unstable.
In this particular instance, the operation indicator will be blinking green to inform you of an unsuitable
environment.
When the indicator blinks in green, check if there is a large metal object in front of the sensor, and place it as
far as possible from the sensor.
* Even if the indicator light blinks green, it does not systematically signify that the sensor is operating in an
unstable way.

Calibration Error
The following setting parameters are to be configured if the sensor does not operate as expected in the
system operation check or some error occurred. They are not necessary for a normal installation.
●How to Change Sensitivity Setting
[1] Press the Mode Select button and select [Sensitivity] the mode indicator (red).
Every time pressing the button, the mode indicator moves down by one.
[2] Press the Value button and select the desired sensitivity of the setting indicator (green).
Keep pressing the button until the desired setting is reached. The sensitivity setting switches from 1 to 2, 3, 4,
5, and then returns to 1, 2, and so on. (e.g.: If the sensitivity is 3, three indicators are turned on).
Sensitivity setting and vehicle detection capability have the following relationship.
In normal cases, use with the sensitivity level of 3.
Setting change may be needed if:
●Increase…… Sometimes a vehicle is not detected
Detection response is too slow
●Decrease……Reverting back to non-detection status will take more time.

●How to Change the Human Cancellation Setting
[1] Press the Mode Select button and select [Human Cancel Adjust] the mode indicator (red).
Every time pressing the button, the mode indicator moves down by one.
[2] Press the Value button and select the desired sensitivity of the setting indicator (green).
Keep pressing the button until the desired setting is reached. The sensitivity setting switches from 1 to 2, 3, 4,
5, and then returns to 1, 2, and so on. (e.g.: If the level is 3, three indicators are turned on).
The human cancellation setting and human cancellation capability have the
following relationship.In normal cases, use with the level of 3.
Setting change you may need:
●Increase the value if: A human is detected sometimes
The sensor detects a vehicle passing close to (but not in) the detection area
●Decrease the value if: A vehicle is not detected sometimes
Response of detection is too slow
1. Press the Mode Select button and select [Human Cancel Adjust].
2. Press the Value button to select the sensitivity.

5-3 Presence Detection Timer
The presence detection timer periodically performs automatic calibration. It can
prevent the sensor from detecting an object for a long period of time.
If there is any of the following problems, configure the presence detection timer.
●The sensor keeps detecting due to an object in the detection area.
●The sensor keeps detecting after installing a roadblock.

Sensor
●If the sensor detects a moving object while the timer is active, the calibration will not be
performed and the timer period will be extended.
●There is no Presence Detection Timer for the ultrasonic detection area.
NOTE
[1] A sign is placed in the detection area of the
microwave sensor and it detects the sign.
[2] When the time period of the presence detection
timer runs out, the sensor no-detection because
the sign is memorized as a background.
[3] When the sign is removed, the sensor may stay
in a non detection, or detection state. If the
sensor stays in the non detection state, it may
have less sensitivity for a while.
[4] If the sensor detects in [3], and when the time
period of the presence detection ends, It will be
memorized again as a background and be in
no-detection status.
