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-122 is a microwave sensor for intersection management. The output consists of 2 relays which
can be triggered on movement and/or when vehicles stop at the stop line. The product can count the vehicles
which are passing the stop line.
1. Unpack the unit and check the following items are in the box:
A. Radar with rear side socket
B. Cable with connector
C. Mounting bracket
D. User’s guide and tune up procedure
2. Set the encoders according to your choice for the different parameters (see “Tune up procedure”). For specific
TMA configurations, the setup is made through RS-232. The encoders are then inoperable.
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 CABLING, 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.
