Parallel System
Phase Sequence
Error
One or more of UPSs which operate in parallel mode do not match
in phase sequence.
53
Battery Start
UPS was given the command to start from the battery.
54
Parallel Start Error
One or more of UPSs which operate in parallel mode could not be
prepared to operate.
55
Inverter Error
UPS couldn't prepare the inverter voltage when it was started.
56
Output Off
Static transfer switches all disabled. The loads cannot be
energized.
57
Normal Mode
UPS is operating in the normal mode, loads are energized through
rectifier – inverter line.
58
Battery Mode
UPS is operating in the battery mode, loads are energized through
battery – inverter line.
59
Bypass Mode
UPS is operating in the bypass mode, loads are energized through
bypass line.
60
Maintenance Bypass
Mode
UPS is operating in the maintenance bypass mode, loads are
energized through maintenance bypass line.
61
Parallel Mode
2 or more UPS are operating in power sharing mode. Load is fed
through UPSs’ inverter lines.
