Cause : Power card supply comes when the supply on the power card is out of range. There are 3 power supplies generated by the switch mode power supply (SMPS) on the power card: 24 V, 5 V, and ±18 V.

  1. When powered with 24 V DC with the MCB 107 option, only the 24 V and 5 V supplies are monitored.
  2. When powered with 3-phase mains voltage, all 3 supplies are monitored.
