INSTALLATION
INITIAL SETUP, MOUNTING HEIGHT, ANGLES, CLEARANCE
Install the 316 on a suitable bracket ensuring that it has an unobstructed view of the stopline and the lane required for detection preferably between 3 and 5 metres from the ground. A height adjustment bracket is available for greater adjustment especially where the detector may be obscurred 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 centre of the face of the unit is pointing at the stopline. If the mounting is such that the installer can’t view the exact direction that the radar is pointing, then the following approximations may be useful.From the mounting pole, if the distance to the stopline is;
a) <1m – fully decline the radar b) 1m – 45 degrees declination c) >1m – 30 degrees declination
It is also advisable to stand behind the mounting pole at ground level to confirm the pan angle is correct.

USER CONFIGURATION
INSTALLING THE LIVEWIRE™ GRAPHICAL USER INTERFACE (GUI)
To 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 posses a Livewire™ account, please register on the website and request a “Livewire access key”.
LIVEWIRE™ APPLICATION SETUP
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 application will search for all bluetooth devices within range and will display these once discovered. 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-“Junction01” (maximum 11 charaters) this is discussed later on page 18.
ConnectingThis screen will appear once you have selected the required radar to connect to. The connection process should only take a few seconds, 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 - refer to the Troubleshooting section on for further information.

USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP
Traffic flowThe next view options allow the software to form a more accurate representation of the road layout - Simply select the side of the road down which the traffic is travelling. This is the operators preference and has no effect on the 316 performance.
DistanceThis is the distance from the base of the pole to the FIRST stop line within the field of view - if there is an advanced stop line, then that should be used as the point of reference.
ASLIf the road has an Advanced Stop Line, select yes, otherwise select no.
11
USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP
Coarse angle setupThe basic software configuration is now complete and you will be presented with the following window. Note the information shown in the help bubble (“?” top left) provides a reference for the following steps. 1. Adjust the angle of the radar - as per the installation instructions on page 6, the face of the radar should be pointed at the stopline. If this is not the case, adjust this now.
2. Click “reset graph” This will allow you to view the status of the radar from a known point.
3. Wait for multiple moving vehicles - The radar will show these vehicles as indications in the activity bars within the range boxes as an average of the amount of activity.
4. Wait until at least 2 golden boxes highlight green - This will indicate when the radar has detected sufficient activity in order to be configured further. If the boxes do not highlight green despite the passage of multiple vehicles or highlight red over a few cycles of the junction, then the angle of the radar may require adjustment.
If so, adjust the radar pointing angle accordingly and click the on the top left of the window to run through the coarse setup again. Repeat steps 1 to 4 as necessary in order to continue.
Note that if the 316 is detecting at a point that differs from the information entered during the “Road setup” then a view similar to the image right will be shown and the suggestion “Tilt radar” will appear.
The screen right shows the expected display during the coarse setup procedure - Note that the software is stating “Wait for more vehicles”, there is one green box and activity shown by the beige bars in several boxes.
12
USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP
Coarse setup completeThis shows multiple highlighted boxes and indicates that the radar is pointed accurately at the stopline and the road - Note that the GUI is stating “Coarse angle setup complete - further fine tuning may be required”
It is worth noting that the image on the right 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 may need to be adjusted before further progress can be made.
The greyed out Continue button will illuminate once the detector has determined its detection zone.
Detection zone setupIn zone set-up you will initially be prompted to use Auto set-up, a choice of auto or manual is available and is dependent on individual junction configurations, if auto is chosen the set-up finishes at the manual stage so settings can be changed if required
The user is now required to check the validity of the detection zone and adjust if necessary. It is important to note that the boxes on the display that relate to the stopline and the preceding area on the road surface MUST have a high occupancy rating (showing activity when vehicles pass through and/or stop within those boxes). This can be checked by resetting the vertical bar indicators by clicking
Note: If a vehicle is not detected in the furthest right-hand zone box then a detect (queue) state WILL NOT be generated. For examples, refer to the pages 15-16.
The image above shows the default zone settings. In order to configure the zone as per the site requirements left click on the icon.
The zone can be adjusted by left clicking and holding the mouse on either end of the zone and then by dragging the cursor in the required direction.
Once the zone has been configured as required, the user must save the adjustments by clicking the save icon
13
USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP
Auto zone setupThis 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.
This 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.
Auto completeIf the option to use the Auto Zone setup 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 configure the zone based upon the information it has received during the coarse tune process. This may not directly reflect the actual site requirements in all cases and the zone may require further adjustment.

USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP - EXAMPLES
Zone example 1This shows the zone having been adjusted to boxes 2,3 and 4.
Zone example 2This shows the zone having been adjusted to boxes 2,3,4 and 5.
Zone example 3The 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, the unit will detect queues.
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.
Alternatively, it may also be possible to achieve the same results by altering the radar angle and direction in small increments, and resetting the graph 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 then a detect (queue) state WILL NOT be generated.

USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP - EXAMPLES
Zone example 4The image right shows an example of a road with a right filter lane where detection is being setup for the lane indication straight on.
Zone example 5The image right shows an example of detection of a filter left lane when setting up for multiple lane applications.
Zone example 6The image right shows an application where the detector is positioned forward of a 10m stop-line.

USER CONFIGURATION
LIVEWIRE™ APPLICATION SETUP - VALIDATION
Free flowing trafficThis shows a vehicle moving through the detection zone and is the expected visual representation of activity within the radars detection range.
Road emptyThis status should only be shown when there is an absence of traffic either moving or stationary. If this state occurs during setup when traffic is in the detection zone, then the radar may need to be re-angled.
DetectThis shows the radar in the Detect state. Note the activity before and in the zone as shown by the activity bars and the “Traffic Stationary” road state.
If the detection zone is next to a pavement / parallel footpath, a WALK TEST is required. This involves walking briskly down the edge of the pavement and stopping adjacent to the stop-line to determine if the 316 will detect pedestrians. 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. Once the user is satisfied that the radar is configured correctly and that all checks have been made, the radar settings should be saved by clicking the Save icon

HELP
TROUBLESHOOTING
Please refer to the safety warning at the end of this manual.
LED stays on permanently on power upThe 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.
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.
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.
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 17.

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.
