The battery has voltage (at least 12 V)
- The traffic signals require a healthy battery in order to start, so it is important that a healthy battery is connected before continuing with further troubleshooting.
The wiring is intact
- Check the cable between the battery and the traffic signal to make sure it is intact and not damaged.
The pins in the traffic signal connector are not pushed in.
- Check that all pins in the connector coming from the traffic signal are at the same height and that none of them are pushed in.

If the cable is longer than approximately 15 cm, remove the green lamp and check whether there is a waist on the cable. If there is a collar as shown in the picture below, contact Berlex Support: +46 303 922 10.

If there is a black connector inside the modem instead of the cable shown in the picture above, check the connector to make sure it has not been damaged internally.

In the picture below, the arrow points to the jumper that breaks if the cable has been stretched and has damaged the connector.
