  • Page 49 (Panel Drive Voltages Vda) Voltage Distribution Analysis of a shorted Vda condition Depending on the model, a short circuit of the Vsus can cause a 3 fast blinks or a normal 8 blinks shutdown condition. A shorted Vda caused by the panel will not trigger a 3 nor an 8 blinks shutdown condition because of the 1 ohm fusible resistors used on the C boards.
  • Page 50 Voltage Distribution (Panel Drive Voltages Vda) Analysis of a shorted Vda condition A shorted Vda caused by the panel will not trigger a 3 nor an 8 blinks shutdown condition because of the 1 ohm fusible resistors used on the C boards.
