site does not have power facilities, new
power lines must be routed to the sign or a
different installation site will be required that
has power.
Solar Kit Installation:
Check the installation site for a clear view of
the sky for the solar panels. It is particularly
critical that the solar panels have a clear
view to the south at the angle of the sun in
the winter time. If your site does not have a
clear view of the sky, a different installation
site must be selected that has a clear view of
the sky.
Battery Charger Kit Installation:
Check the installation site for an existing
lighting power source that can supply AC
power to the driver feedback sign at night.
Determine the voltage that the street lighting
is operating on and verify that the correct
battery charger kit has been selected.

In mounting the sign use a minimum of 6 bands
spaced evenly on the back mounting bracket or a
minimum of 6 each, 3/8” bolts with flat washers and
other mounting hardware as required.
Site Survey
Before installing the Driver Feedback Sign, an
installation site must be selected. It is very important
to select a site with the following characteristics:
5.3
There must be a clear view of the sign from the
roadway for at least 500 feet and, the viewing area
must be clear of trees. Attenuation of the radar’s
signal, caused by trees, may reduce the radar’s
effective range.
The 14” Driver Feedback Signs are provided with
mounting provision at the back of the sign. The
mounting provision is designed to be banded and/or
anchored/bolted to the mounting structure.
Anchoring and bolting is recommended over banding
to improve performance in areas where high wind is
normally expected and for increased crash integrity
capability. Listed below is some additional
mounting hardware that may be used to mount the
sign to a pole:
Do not install the sign facing an intersection or
bridge if possible. If the sign must be installed
facing an intersection or bridge, the sign should be
located at least 400 feet away. Cross-traffic may be
registered by the radar as an oncoming vehicle.
The sign should be located at least 200 feet away
from large street signs that fall within the radar’s
detection zone and cause the radar to reflect its’
output. Reflecting the radar’s output by objects such
as signs may cause vehicles to be detected in the
opposite direction.
Preferred method:
Pelco Bands, P/N: US-8124-06
Pelco Banding Buckles, P/N: US-8124-56
Tools Needed: Pelco P/N: US-8120-01 and
US-8120-06 handle.
Another option is the EZ-Band Kit P/N US-8500
(one per band) with US-8122-06 banding, or US8504 with US-8124-62 banding. Standard tools can
be used to tension these; however they are not as
secure since standard tools can also remove them.
• Pelco can be contacted at 1 (405) 340-3434
for product and ordering information.
•
•
•
Install sign in roadway geometries that allow clear
view of the sign’s display and provide the most
efficient radar detection zone.
Proper site selection will provide the greatest traffic
calming effect and sign performance.
5.2
Mounting Bracket
Pole Selection
Pole selection for the Driver Feedback Sign is an
important element in the installation design. Poles
selected for mounting the DFB must support the
weight and wind loading of the sign, power option
and any static signs. Crash worthiness may also need
to be considered. Use a break-away pole and attach
the display using a 6 point bolt structure to improve
crash worthiness.
5.4
Sign Test Procedure
Connect the sign to the appropriate power source.
Verify that the display and display controller are
functioning correctly.
Using the DFB software place the sign in test mode.
13
14” LED Driver Feedback Sign Installation Instructions (029-04153-0000)
The sign then cycles through its test character set
until the sign is taken out of test mode using the DFB
software.
Visually verify display functionality. If the sign
fails, refer to the Troubleshooting section of this
manual for help.
Verify that RADAR mode is functioning correctly.
Using the SafetyCalm™ software, set the display
status to on. The sign enters its normal mode of
operation. Note: The factory setting powers up with
the radar on.
Place the sign in a location where vehicles are
approaching the sign within the range of the radar.
Visually verify that the sign is displaying a speed
value approximately equal to that of the approaching
vehicles.

Sign Installation
A hanging bracket(s) has been provided on the sign
chassis to assist in attaching the sign to a structure or
pole. The bracket(s) should be mounted so that the
bottom of the sign is about 7 feet off the ground as
shown in Figure 6-1. (Measure 122” from grade up
the pole(s) and mark. Center the mounting hole of
the hanging bracket(s) on the mark(s).

Mounting the sign
Installation
This section contains installation procedures for a
Driver Feedback Sign (DFB). The DFB requires 12
VDC power to operate the sign. Depending on the
power option selected to provide the 12 VDC, the
signs can be powered by continuous AC power, a
solar kit or street lighting power.
14
14” LED Driver Feedback Sign Installation Instructions (029-04153-0000)
Assemble DFB sign ECS to mounting bracket as
shown in Figure 6-3, but do not tighten down or
install lock bar. Mount the power source device or kit
to the pole or structure.
March 28, 2013
The sign may display speeds of vehicles traveling
perpendicular to the sign’s face. Ensure that the sign
is not installed within 400 feet of an intersection,
bridge, or similar roadway feature.
Obstructions such as a static sign, building,
inclination, or similar factors may influence the
distance range of the vehicle detection and the
accuracy of the displayed speed values.
The radar needs to have a clear view of the targeted
vehicles. Avoid mounting the sign behind trees,
poles, tall parked vehicles, and so on.
The system should not be used in the range of road
turns and bends. This may result in the sign
displaying speeds that are lower than the actual speed
of the object.
Figure 6-3
Installing the ECS
6.1.3 Radar Properties
The distance range of all microwave detectors
depends to a large extent on reflection properties of
the measured objects and interference properties of
the nearby surrounding objects.
6.1.1 Aiming the Sign
The 14” DFB contains an internally mounted radar
speed detector to detect on-coming vehicle speed.
The radar requires that the face of this sign be aimed,
allowing the radar to accurately detect vehicles. For
best operation, the face of the sign should point into
traffic as close to parallel with the direction of traffic
flow as possible. For best accuracy, the angle of
incidence should be 5 degrees or less. Angles of
incidence greater than 10 degrees will display slower
than actual vehicle speed. For best range try not to
aim the sign so that the lanes of receding traffic are
in the radar detection area.
The following properties can be expected:
Vehicles that appear larger and flatter to the
microwave beam axis provide a longer radar
detection range.
A less absorbing and scattering reflective surface
results in a longer detection range.
As more objects obscure the radar measurement
beam, the detection zone will become shorter
(diffraction scattering, foliage losses, shadow losses,
and so on).
6.1.2 Sign Radar Operation
The following factors have a reducing effect on
the distance range:
The sign’s radar continually emits weak levels of
microwave energy at a specific frequency (K-band,
24.15 GHz) and scans for returns from moving
objects. When this microwave energy encounters an
object, some of the energy is reflected back to the
radar. If the object is moving, the frequency of the
reflected microwaves is changed by an amount
proportional to the relative speed of the moving
object. This characteristic frequency change is
known as “Doppler Effect.” The radar unit measures
the difference between the frequency of transmitted
energy and the frequency of the reflected energy to
determine the relative velocity of the moving object.
Ensure that the following items are taken into
consideration when choosing an installation site for
the sign:
Buildings, trees, poles, parked cars and containers,
which hamper the “free sight” of the radar detector
and may lead to shorter ranges.
Influence by weather, rain and snow lead to
absorption losses at the radar detector.
“Blinding of the Radar” by stationary traffic in the
radar beam, or extraneous moving objects like
branches of trees, birds and so on.
Depending upon vehicle type and reflective
properties, the typical passenger car will have a
detection range of 1000 feet for the 14” DFB. For
trucks, the distance range is about 50% to 100%
longer due to the larger reflective surface. For
motorcycles, distance range is reduced by 50%.
15
14” LED Driver Feedback Sign Installation Instructions (029-04153-0000)
The above mentioned detection distance limits are
not a limitation of the radar itself, but the optimal
viewing distance of the driver. We reduced the
radar's detection range so that the driver can view
his/her speed clearly while approaching the sign.
The optimum distance range has a sign mounted at a
height of 7 feet from grade to the sign’s housing
bottom.
March 28, 2013
Note: The conduit forms part of the ECS Theft
Security. ECS must be positioned properly before
the conduit is installed.
The display may have been provided with a
TraffiCalm power supply option that derives power
from either solar or AC line. These kits are provided
with a DC power connection cable assembly that
terminates to a DC Barrel connector (2.5mm x
5mm). If the power supply was not provided by
TraffiCalm, then the termination is unknown and
most likely a pair of 18 to 14 AWG insulated wires.
The minimum recommended wire size is 18 AWG
for up to 6 feet. For greater lengths increase the wire
gauge as needed for a 3 Ampere load to keep the
conductor voltage loss at less than ¼ volt (250mV)
total for both conductors. (Example: for a 15 foot run
between the power supply box and the sign 14 AWG
wire is required.).
Additional Notes:
1. Installations will need to include proper
grounding per state and local code.
2. Wiring conduit can be run either inside or
outside the pole depending on the pole type.
6.1.4 Measurement Angle
The angle between detector beam axis and the
movement axis of the detected vehicle (see Figure 64) has direct impact on the measured speed. This is
expressed by following formula:
vmeasure = vabsolute x cos ϕ
with ϕ: measuring angle
The ideal measurement angle is 0°, this means
vmeasure = vabsolute and movement axis and radar
beam axis are identical in this case.
IMPORTANT
The error in the speed values will become greater as
the measurement angle increases.
Connecting the Sign to power (See Figure 6-5):
1. Make sure the power supply is disconnected
from the display power wires or cable. In
the case of a battery powered system make
sure that the batteries are all disconnected. If
the system has a solar panel make sure that it
was disconnected also.
2. Install liquid tight conduit from the power
supply to the field wiring plate from the back
of the sign using one of the provided
knockouts.
3. Route the power supply 12VDC Positive,
common, and Earth \ chassis ground wires
from the power supply to the sign through
the conduit.
4. Connect the Earth ground to the stud
provided on the field wiring plate from the
back of the sign using a ring lug (user
provided).
5. If the DC wiring terminates to a barrel
connector, cut the cable at the barrel
connector, and separate 2” of the cable into
its two conductors. The positive conductor
is marked with a white stripe.
6. Strip the ends of the conductors ½”.

7. Put the positive conductor into the terminal
strip position marked “+12VDC”.
8. Put the DC common conductor into the
terminal strip position marked “DC COM”.
9. Fasten the field wiring plate back onto the
back of the sign.
10. Connect battery powered systems back to the
batteries, or line powered system to line. For
solar powered systems be sure to reconnect
the solar panel.
11. Fasten the ECS into place.
a. Align the ECS to the chassis using
the features provided and tighten
down the 12 fasteners to secure the
ECS to the sign face.
b. Install the lock bar and fasten into
place using the provided hardware.
Refer again to Figure 6-3. Install a
padlock or other hardware to
discourage tampering.
12. Test the sign to ensure the installation was
successful. See section 1.16 for information
on sign testing.

The external Beacon connector has the following pin
assignments.
Figure 6-6. External Beacon Connections
Pin 1 Fused (1A) 12VDC output from the
Display DC input
• Pin 2 Opto-Isolator Positive common
• Pin 3 Beacon DC control #1 (provides DC
Return when active)
• Pin 4 Beacon DC control #2 (provides DC
Return when active)
• Pin 5 Beacon Output DC COMMON (Fused
at 1A)
• Pin 6 Display Common
Typically you would either provide field (beacon)
power to position 2 (+) and common to 5 (-), or
jumper 1-2 and 5-6 if no isolation is needed to draw
power off of the display batteries. In either case, the
beacons are wired to the positive source and the
display outputs provide the DC Common path. The
outputs are rated for up to 60V standoff and ½ Amp
of current.
•
Default behavior (Control Mode):
• Output #1 (pin 3) is goes active when a
vehicle speed crosses above the over limit
setting.
• Output #2 (pin 4) is active whenever the
display is in RADAR mode.
Figure 6-5. 14” DFB Wiring
6.1.6 External Beacon Connection
TraffiCalm LED Driver Feedback Signs have
provisions to connect external beacons that can be
controlled by sign functions. The connections are
made with a six pin connector located on the bottom
of the ECS under the access panel. See Figure 6-6.
17
14” LED Driver Feedback Sign Installation Instructions (029-04153-0000)
typically ON whenever the display has sufficient
power to operate, and is switched OFF when the
batteries are low to help protect batteries against over
discharge. In the case where the display is set to
operate from a AC power source, the modem output
stays on continuously or whenever the display has
power. The switched power rating is 12VDC at 2A
and is protected by a self-resetting fuse.
The beacon outputs can be programmed with the
DFB software for two other modes of operation.
•
Beacon mode 1 causes the beacon control
outputs (pins 3 and 4) to activate alternately
at a 1 Hz rate when the sign is active in radar
mode.
•
Beacon mode 2 causes the beacon control
outputs (pins 3 and 4) to activate alternately
at a 1 Hz rate when a selected sign speed
threshold is exceeded.
March 28, 2013
WiFi modems, GSM modems, and terminal servers
that are used to interface a serial device to a network,
must each be able to operate in a “transparent” mode.
See drawings in Appendix B for recommended
beacon wiring.
In a transparent mode the modem receives and
transmits data using the network protocols while
stripping away the network layers before forwarding
data to the display, or adding the network layers to
data from the display before transmitting them over
the network. Essentially, the modem or terminal
server behaves as a direct connection to the PC
running the software as far as the display is
concerned.
WARNING
The beacon outputs of this display should not be
used as the only means to notify drivers of speed
limit changes in school or work zones.
- Use an approved safety device or signage to
notify drivers of traffic zone changes that may
affect the safety of pedestrians, workers, or
drivers.
With these styles of communications interfaces the
network provider services are the responsibility of
the owner / operator of the display.
CDMA modems are more interactive with the
display, requiring the display to initiate connections
to the network and listen for server requests for data
connections. This style of modem would typically
be preconfigured at TraffiCalm’s factory or by the
service provider.
6.1.7 Communications
In addition to the built in Bluetooth communications
device the display has an RS-232 port that is
accessed via a connector on the display control
assembly. The cable used to connect to the display
varies with the kind of communications device to be
used. Cable A is used to provide direct serial
connections to other RS-232 equipped devices such
as a PC. Cable type B allows serial connection to a
G200 GSM modem device and provides a power
connection for the modem. Cable type C provides a
connection to a WiFi modem device along with a
standard 2.5mm x 5.5mm power connector. Cable
type D is intended for connection to a Verizon or
Sprint compatible CDMA modem operating on the
2G or 3G network.
The modems and cables can be obtained from
TraffiCalm Systems.
6.1.8 External Modem Operation
When the display is connected to a modem through a
cable assembly as described in section 6.1.7 the
power to the modem provided through the integral
connector is switched by the display controller. It is

Troubleshooting
This section provides troubleshooting information
intended for use by technicians who are familiar with
this type of variable message sign. The right
knowledge combined with a systematic approach to
the problem will result in an efficient and timely
repair. Once the problem is identified, analyze why
the failure occurred. If a maintenance issue led to the
failure, include it in the next preventive maintenance
trip to all of the signs. If a fuse blew, find out why
instead of just replacing fuse after fuse. One small
problem may be an indication of a larger problem
about to happen. Fix problems before they happen
whenever you can.
To use this guide, start at the beginning of the
troubleshooting table (see Section 7.1). Each
observation listed in the table describes a basic
problem that a user might encounter and suggests a
course of action. In some cases, the course of action
is to look at another section of the table. The
situations start out general and get more detailed as
progress is made. Once a description of the problem
is found that most closely matches what you observe,
follow it to its logical conclusion in the
“Cause/Action” table.
The first step in troubleshooting is to clearly define
the problem. Here are just a few examples:
Is the problem intermittent or continuous?
Is the problem present only in the operation mode or,
does it also occur in the test mode?
If needed, technical assistance is available by
contacting your local partner or TraffiCalm
Technical Service department at 1-855-738-2722.
