Main indicators of system operations
Normal : charge alimentée par l'onduleur bit 4C4 = 1
Danger : charge non alimentée par l'onduleur bit 4C6 = 1
Downgraded : anomalie de fonctionnement bit 4C5 = 1
ou défaut d'environnement
Operating modes
The following section describes the
different states of a Static Switch
cubicle and the addresses of the
bits in the system data array.
Normal operation
Normal: bit 4C4 = 1
Danger: bit 4C6 = 0
Downgraded: bit 4C5 = malfunction dependent
Q5N closed: bit 498 = 1
Q3BP open: bit 497 = 0
Q4S closed: bit 496 = 1
SS open: bit 499 = 0
K2S open (if available): bit 494 = 0
Inverters connected to load: bit 4AE = 1
Load on Mains 2
Normal: bit 4C4 = 0
Danger: bit 4C6 = 1
Downgraded: bit 4C5 = X (N/A)
Q5N closed: bit 498 = 1
