Note 6. Maximum peak voltage of GDU input voltage from power supply should be lower than 25V.
Note 7. If the period for over voltage < 1.0ms (period t1), no fault signal is sent.
`
If the period for over voltage ≥ 1.0ms, fault signal starts after period t2 from 22V of power supply voltage. System should be shut down (Control signal
should be off) within period t3 from fault signal start.
Note 8. GDU Voltage bus (G-K Voltage for GCT) is clamped to be 21V if power supply voltage is higher than 21V after system shut down (control signal off).
