Fresco displays “Power supply voltage too low” error message during start-up.

This error message is displayed when the supply voltage is not sufficient to ensure proper functionality. This error is most likely caused by using an inadequate power supply, or connecting more FCS devices than the power supply can power. To troubleshoot this problem:

  1. If using a PS10 power supply, verify that no more than 3 RBs and a Fresco are connected to each power supply. If this fixes the issue, consider adding another power supply.
  2. Make sure a FCS PS10 (24V 10W) or greater power supply is used.
  3. Verify of power supply wiring.
