THEORY OF OPERATION
The TMA is a microwave sensor for traffic management (traffic data collection, intersection management, warnings,
public lighting management), available in different configurations according to the applications.
The TMA-60 is a microwave sensor for managing warnings and intersections. The output
consists of 1 relay which can be triggered on different speed and range thresholds.
1. Unpack the unit and check the following items are in the box:
A. Radar with rear side socket
B. Sticker for front face
C. Cable with connector
D. Mounting bracket
E. User’s guide and tune up procedure
2. Set the encoders according to your choice for the different parameters (see “Tune up procedure”).
3. Place the sticker on the front face.
4. Assemble the unit with the bracket (see “Tune up procedure”).
5. Place the radar on the field according to configuration and to the specific tune-up procedure.
6. Connect the cable according to the wiring described at p. 6.
7. Power the radar.
8. The LEDs will come on when a vehicle is detected and matches the conditions of the chosen parameters.

SAFETY PRECAUTIONS
Only skilled and instructed persons should carry out work with the radar product. Experience and knowledge about
safety procedures in the following areas may be relevant:
•Working with mains power
•Working with modern electronic and electric equipment
•Working at height
•Working at the roadside or highways
Please follow these safety precautions:
-Make sure the electricity supply is within the range shown on the label and the manual of the product.
-All connections must be made whilst the power supply is switched off.
-Ensure the wiring is correct as shown in the manual before switching on the power supply.
-Never use a damaged radar or cable.
-Opening the outer casing is deemed dangerous and will void all warranties.
-Ensure the radar is mounted correctly. The screws and bolts of both radar and bracket must be firmly
tightened. The radar needs to point to the region of interest for proper detection.
-Ensure the radar is configured properly.
WARNING: For the HV version of the radar, a Residual Current Device (RCD), also known as the Residual Current
Circuit Breaker (RCCB), with a tripping current not exceeding 30 mA must be installed in the supply circuit.

PARAMETERS DESCRIPTION
Depending on the chosen TMA configuration, the settings are made using two encoding wheels with 16 positions
each and/or using an RS-232 link.
The parameters described here are for the TMA-60 configuration. Other parameters may apply to other TMA
configurations.
1 SENSITIVITY
The factory setting fulfills the requirements of the majority of the installations. If the position or the size of the
detection area is not satisfactory, change first the position of the radar (tilt angle and/or height of installation). On
some products, the sensitivity threshold can be lowered to reduce detections beyond the FSK ambiguity distance
(~250 m) and interfering movements at the edge of the detection area.
2 SELF-MONITORING
The self-monitoring applies to the following parts of the hardware:
- Micro-processor oscillator
- Code running
When a failure is detected, the relays are permanently actuated and the flashing LEDs show an error code (see
Tune up procedure for further information).
3 RF CHANNEL
This parameter allows to shift the radar’s frequency. If two units face each other, they must be put on different
channels as to not interfere with each other.
4 SPEED THRESHOLD
This parameter defines (a) minimum speed threshold(s) above which the relay is triggered.
5 DETECTION DISTANCE
This parameter defines the maximum detection range.
6 DETECTION DIRECTION
This parameter defines the direction of the movements which will trigger the relay: approaching, receding or
bidirectional.

CONFIGURATION & TUNE-UP TMA-60
The TMA-60 is equipped with two encoding wheels allowing 16 positions for manual setting.

cover radars without sticker!

LED INDICATOR
1 AT START-UP
At start-up, the LEDs indicate the version number and the type of configuration:
-Green and red LEDs flash alternately: relay check
-Flashing green or red LED: version number
2 IN NORMAL OPERATION
The green LED lights up when a movement meeting the specified criteria is detected.
3 WHEN THE SELF-MONITORING DETECTS AN ERROR
The two LEDs blink quickly (2 or 4 quick flashes followed by a 1 sec break, depending on the detected error):
1. Type 1 failure: code execution and internal micro-controller state consistency. If a problem is detected, the
system is reset.
2. Type 2 failure: micro-controller oscillator monitoring. If a problem is detected, the system enters in “fault
mode”. The LEDs show a code by blinking twice followed by a 1 second pause.
The reset takes 1 500 milliseconds.
INSTALLATION GUIDE
1 GENERAL
•Installation height: typically 3 m. The greater the height, the longer the d dead zone (“no-detection” zone
starting at the foot of the radar pole).
•Tilt or inclination angle: the smaller the angle (radar nearly horizontal), the longer the dead zone (“no-
detection” zone starting at the foot of the radar pole). See title 0, p. 11, for specific use cases.
Figure 7: tilt or installation angle
1.1 ASSEMBLY AND MOUNTING
1. Fix the radar on the bracket:
α= vertical radar opening angle (α= 45°)
β= horizontal radar opening angle (β= 38°)
tilt = Inclination angle compared to the horizon

2. Set the appropriate parameter values
3. Place the radar on the pole pointing towards the approaching or receding vehicles
4. Firmly tighten the screws
