5-4: Static Switch transfer code (for LOADBP event)
The STSW transfer code, given as a decimal, is the sum of the eight components listed in this table.
Each component has its own weight if detected, and a weight of zero if not detected.
COMPONENT
WEIGHT
CONDITION DESCRIPTION
1
Inverter voltage blackout for >3 ms.
2
Inverter peak voltage <185 V (brownout).
4
Inverter peak voltage high <185 V (brownout).
8
Frequency beyond limits (45-65 Hz).
16
Inverter average voltage low.
32
Inverter average voltage high.
64
Instruction for load transfer was received from the controller.
128
Instruction for load transfer was received from the Static Switch.
Example: If LOADBP data = 67 = (64+2+1), this means that three conditions were present:
y (64) Instruction to transfer the load was issued by the controller.
y (2) Low peak voltage detected.
y (1) Voltage blackout encountered.
