INSTALLATION

SITE REQUIREMENTS

The 316 is a single lane detector which tracks the targets when they enter the beginning of the radars beam. Targets must enter the beginning of the radars beam to ensure they are detected and the target must travel all the way through the detection zones (beam) to ensure the radar sees the targets leaving the detection zones and the demand is cancelled.

When selecting a site the following recommendations should be observed in order to optimise performance and ensure a smooth installation.

Correct Installation

A B

A}B

X } A

Traffic merging from the side road: in this scenario it is advisable to latch the demand from the side road 316 in the controller. This will prevent demands from being dropped when the traffic is crawling, due to the main road being blocked.

INSTALLATION

SITE REQUIREMENTS

Traffic Merging

Site Survey

In this scenario the vehicles labelled A in both diagrams are not entering the detection zone correctly and will not be tracked for a sufficient distance by the radar to generate a demand.

Vehicle B has been detected entering the detection zone, but, it is exiting the detection zone incorrectly and the demand will not be cancelled, the vehicle needs to travel past the stop-line for the demand to be cancelled.

When surveying a site it is important to be aware of the requirement for the target to enter and leave the detection zone correctly, to ensure optimum operation.

In circumstances were the side road is seldom used and you decide to deploy the radar, demands that are not cleared and held, will be cancelled by, either:

• Vehicles driving through the detection zones correctly, will cancel the demand that has not been cleared.

• Setting the Presence Time (page 23) to 1 minute; any demands held and not dropped are then cancelled after 1 minute.

INSTALLATION

Radar Mounting & Positioning

Install the 316 on a suitable bracket ensuring that it has an unobstructed view of the stop-line and the lane required for detection, at a height that is between 3 and 5 metres from the ground. A height adjustment bracket (part number BR-129) is available for greater adjustment especially where the detector may be obscured by the signal head. Tighten the mounting nut sufficiently in order to hold the unit in position but to still be able to pan and tilt the 316 as required.

Tilt and pan the 316 so that the center of the face of the unit is pointing down, 1m in front of the stop-line

It is also advisable to stand behind the mounting pole at ground level to confirm the pan angle is correct.

DETAILED LIVEWIRE™ APPLICATION SETUPTo install the 316 Livewire™ interface visit: www.agd-systems.com/downloads log in and select 316 from the downloads page, simply click and follow the on screen instructions.

If you do not currently possess a Livewire™ account, please register on the website (www.agd-systems.com) and request a “Livewire access key”.

Insert Bluetooth dongle now. Launch the software by clicking the 316 Livewire icon and follow the steps shown below. Note: any laptop with an on-board Bluetooth device may require this device to be disabled in order to use the Ezurio dongle. The dongle is available from AGD, quote part number: MS-076

1. The application will search for all Bluetooth devices within range and will display these once discovered.

2. Select the required 316 unit from the list and click continue. Note: that if this is the first time that the radar has been connected to, then the name shown will be the radars serial number. This can be changed to reflect a local layout or personal preference eg:AGD316 -“Pole 01”(maximum 11 characters) this is discussed later on page 22.

Connecting3. This screen will appear once you have selected the required radar to connect to. The connection process should only take a few seconds.

4. If longer than this then you may be required to move closer to the unit and/or away from sources of interference. Alternatively, there may be an issue with the Bluetooth settings on your PC.

Typical activity that is seen in the range boxes.

6. Wait until at least 2 golden boxes highlighted in green.

Move on to page 20 if you have the 2 golden boxes, if you do not have the golden boxes then follow steps 7 and 8.

7. If the boxes do not highlight green despite the passage of multiple vehicles, the height bars show little activity or the range boxes highlight red over a few cycles of the junction, then the angle of the radar may require adjustment.

The suggestions at the bottom of GUI (Graphical User Interface) will aid in adjusting the angle of the radar.

Adjust the angle of the radar and reset the graph, step 4, this is important. This will allow you to view the height bars in the range boxes containing the new readings that represent the new mechanical position of the radar.

8. Follow steps 5 to 6.

Coarse setup complete1. This shows multiple green highlighted boxes and indicates that the radar is pointed accurately at the stop-line and the road.

2. Note that the GUI is stating “Coarse angle setup complete further fine tuning may be required”

The image above shows the expected output in an ideal situation. Provided the radar has highlighted at “least 2 boxes”at your desired area of detection the next step can be actioned. If the radar has not detected activity or only detected a small amount, then the radar pointing angle and direction will need to be adjusted before further progress can be made, go to page 14 step 7.

3. Select the greyed out “Continue icon”, which will illuminate once the detector has determined the detection zone.

Detection zone setup1. After pressing the “Continue icon” you will be presented with a screen, similar to the one opposite.

The exact position of the turquoise boxes will be dependent upon the site.

2. You can fine tune the detection zone to optimise site setup.

3. The detection zones (turquoise boxes) can be moved to optimise site setup using the zone set up icon.

USER CONFIGURATION

INSTALLING THE LIVEWIRE™ GRAPHICAL USER INTERFACE (GUI)

4. IMPORTANT

There must be activity (page 13) in the zone at X, just before the turquoise boxes.

If there is no activity in this zone there will be no detection of the targets.

This zone is a “trigger point” that tells the radar algorithm to start tracking vehicles.

The amount of activity does not matter but there must be activity.

5. Auto zone setup will allow configuration of the detection zone.The prompt “Would you like Livewire to automatically configure a valid zone?” will be displayed and the user can select either yes or no.

Note: that the software’s auto setup will configure the zone based upon the information it has received since the last time the reset graph button was clicked.

Selecting “Yes” the auto zone may configure a zone that may not directly reflect the actual site requirements in all cases and the zone may require further adjustment. The user is given the chance to make these adjustments after the auto zone set-up is complete.

6. If the auto zone set up option is used and the software has sufficient data to configure the zone, the following message will appear and the zone will be represented by the blue boxes.

Note: that the software’s auto setup will figure the zone based upon the information it has received during the coarse tune process.

LIVEWIRE™ APPLICATION SETUP - EXAMPLES

Zone example 1This shows the zone having been adjusted to boxes 2, 3 and 4. With the trigger point, box 5 having activity .

Zone example 2This shows the zone having been adjusted to boxes 2, 3, 4 and 5. With the trigger point, box 6 having activity.

Zone example 31. The image right shows a shortened zone between boxes 3 and 4 to cover vehicles and not bikes.

As per the previous instructions, as long as there is reliable activity in box 4 and the trigger point, box 5, the unit will detect queues.

2. If at this point you find that the unit isn’t detecting moving or stationary traffic or is only showing activity over a small portion of the expected area, it is recommended that you re-enter the coarse setup and re-point the radar accordingly.

3. Alternatively, it may also be possible to achieve the same results by altering the radar angle and direction in small increments, and resetting the cream activity bars after each angle change in order to determine the most accurate pointing angle. Note that in this case, the zone boxes may require adjustment also.

Note: If a vehicle is not detected in the furthest right-hand zone box (5 in the above example) then vehicles will not be detected.

USER CONFIGURATION

LIVEWIRE™ APPLICATION SETUP - VALIDATION

Final Configuration Check 1. If the detection zone is next to a pavement / parallel footpath, a WALK TEST is required.

This is illustrated in the set-up video available on You Tube: https://www.youtube.com/watch?v=AsLpFOgOBh0

This is to ensure that pedestrians do not interfere with the detection, by causing false detects and cancelling the demand.

2. By walking down the edge of the pavement from a distance of 10m from the stop line towards the detector ensure you are not being picked up by the radar.

3. If there is no queue detection, save the current settings, if queue detection occurs, then rotate the radar slightly away from the kerb and test again.

4. If you have a road layout like the one opposite, observe the right turning traffic, if the traffic is causing false detects and cancelling demands then adjust the radar slightly away from the right turn lane and test again.

5. If the there is no queue detection then follow step 3.

6. Fully tighten the mounting nut and test for a final time.

LIVEWIRE™ APPLICATION SETUP - TOOLS

ToolsThe tools menu can be accessed by clicking on the following symbol

Within the tools menu, the following options exist as shown by the image opposite.

1. The enable / disable LED option Allows the user to define the status of the detect LED on the front panel of the radar. If the LED is enabled, then the LED will activate when a valid target is detected and vice versa when disabled.

2. Bluetooth name changeIn order to change the Bluetooth device name of the radar, the user is required to click the “Change Bluetooth Name” option, at which point, the Livewire™ application will interrogate the radar and will display the following screen. Once the software has determined the Bluetooth name, the user can alter this accordingly and save by clicking “update”. Maximum number of characters is limited to 11.

Once the name change has been actioned, you should be presented with the following message of confirmation, if not, the bluetooth signal may be weak so re-adjust your position and try again.

Note: Windows remembers the Bluetooth name in order to enable a quick connection and Windows will need to be re-started to refresh with the new name. Till you refresh, the old name will still be shown.

USER CONFIGURATION

LIVEWIRE™ APPLICATION SETUP - TOOLS

3. Restore factory defaultsThis option allows the user to restore the radar to its factory default settings. Note that this option will delete any configuration setup that has previously been saved and that the radar will require configuration before it can be used.

4. Reboot 316The following image shows the process of a reboot. The Bluetooth connection will remain active and the configuration will be held during this process.

This will only take a few seconds.

5. Advanced settingsUnder the “Advanced settings” option within the tools menu, it is possible to alter the detection timeout. The default setting is 3 minutes.

If you have problems with the radar holding the demand then a reduction in this value from its default of 3 mins is recommended.

6. Firmware updateThe 316 Livewire will come with a default version of firmware (the latest at the time of release) if the user wishes to upload a version that is not the default please contact AGD for further instruction.

7. CLIThe Command Line Interface or CLI icon opens a password protected terminal window through which debugging and fault finding can be performed. This option is normally restricted to users, but access may be granted by permission of AGD Systems.

TROUBLESHOOTING

Please refer to the safety warning at the end of this manual.

LED stays on permanently on power up1. The unit has failed to boot up and will try again, if it still fails to power up correctly try unplugging the

unit for a few moments and reconnect. Continued failure to boot up will require returning the unit to AGD.

Power on LEDs do not flash during start-up1. Make sure the unit is wired correctly to the power source. An incorrect connection may cause

unexpected or dangerous behaviour.2. Operating voltages are labelled at the top or rear of the unit. Ensure the power source is able to output

a suitable voltage.3. Where applicable, ensure the power source is current limited to a reasonable value. The unit may

draw twice the typical operating current during start-up.4. Successfully powering a known serviceable unit may confirm a fault with another. Please contact AGD

for further advice.

Unit does not detect vehicles1. Ensure the unit is powered on. Check the front power-on LED flashes after 15 seconds, 5 times during

start-up.2. The rear detect LED will always illuminate during detect. This should be used as a reference for when

the unit is in detect. The front detect LED is configurable and may not be enabled.3. When monitoring an opto / relay output, ensure they are connected correctly to external equipment.

The common line must always be used whether normally open or normally closed is required. Check that the outputs toggle when the rear detect LED changes.

4. Ensure that the radar is mounted and angled correctly and that the GUI has been configured for the location.

5. Ensure the radar has been configured correctly using the 316 Livewire™ application.

6. If there are still issues with detecting vehicles: Reset detector using default mode. Follow the installation instructions on pages 7 - 10. Followed by setup on pages 11 to 17.

Radar is not clearing detect state when vehicles have left the zone1. Check angle of declination of radar as it may need to be angled a little further down so that it can see

targets leaving the area.

2. Please see page 8 - 10

Unit enters detect without any targets / intermittently1. Check the immediate mounting area for potential sources of interference. Unwanted noise may be

caused by high-power radio / telecommunication transmissions or very high current / voltage sources.

2. Carry out a walk test, page 21, final configuration test.

26

TROUBLESHOOTING

Unit cancels demand without any targets / intermittently 1. Ensure the field of view is free from obstruction. In particular, swaying cables or branches may cause

intermittent detection.2. Extreme weather may affect radar performance. Hail, snow and heavy rain make it more difficult for

the detection algorithms to make accurate decisions. 3. Fast-moving pedestrians, joggers and runners may appear as valid targets to the radar.

A walk test may be required in order to confirm the radar pointing angle is correct - see page 21.Cyclists

1. Cyclists can be detected but they tend to move while waiting for the signals to change and therefore the performance may not be as expected with demands being falsely cancelled.

IMPORTANT

IMPORTANT INFORMATION

Low Power Non-Ionising Radio Transmission and SafetyConcern has been expressed in some quarters that low power Radio Frequency transmission may constitute a health hazard. The transmission characteristics of low power radio devices is a highly regulated environment for the assurance of safe use.

There are strict limits on continuous emission power levels and these are reflected in the testing specifications that the products are approved to. These Type Approval limits are reflected in the product specifications required for a typical geographic area such as those for the EU (ETS300:440), for the USA (FCC part 15c) and for Australia/New Zealand (AS/NZS 4268). The limits adopted in these specifications are typically replicated in many other localized specifications.

The level of safe human exposure to radio transmission is given by the generally accepted guidelines issued by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). This body has issued guidance for limiting exposure to time-varying electric, magnetic and electromagnetic fields (up to 300 GHz) which are quoted below.

Note 1 Values are calculated conversions for comparison purposes.

Note 2 Other equivalent limits include; Medical Research Council Limit of 10mW/cm2, IACP limit of 5mW/cm2 (at 5cm) and UK CAST limit of 5mW/cm2

Note 3 Calculation is made on the assumption antenna is a point source therefore the actual value is likely to be significantly less than that quoted. Note that a theoretical max level at a 5cm distance (which gives 0.318mW/cm2) is at a point in the field where the radar beam is not properly formed.

Note 4 Comparison for product model 316 operating in the band typically 24.050GHz to 24.250GHz

From the table it can be seen that it is extremely unlikely that a potentially hazardous situation could occur owing to the use of such low power devices.

It is considered to be good practice not to subject humans to radiation levels higher than is necessary. In a works environment where multiple equipment on soak test are to be encountered then it is considered good practice to contain the equipment in an appropriate enclosure lined with radar absorbing material.
