Why tau T-SKY automation does not start?
- HhillwilliamJul 26, 2025
If the automation system isn't starting, several things could be the cause. First, use a multimeter to confirm you have a 230 Vac supply voltage. Next, ensure the NC contacts of the card are normally closed (3 green LEDs lit) and the red LEDs for opening commands are off. Also, verify that dipswitch 6 (fototest) is set to OFF and trimmers FRC and FRA are at their maximum values. Finally, use a multimeter to check that the fuses are intact.
