Woodward LS-5 v2 Series - System a Operating Voltage; Frequency

Phase - neutral The phase-neutral voltage will be
monitored and all subsequent
parameters concerning voltage
monitoring "system A" are referred to
this value (VL-N).
All The phase-phase and phase-neutral
voltage will be monitored and all
subsequent parameters concerning
voltage monitoring "system A" are
referred to this value (VL-L & VL-N).
This setting is only e󰈠ective if "SyA.
voltage measuring" (parameter 1851)
is con󰈡gured to "3Ph 4W".
Notes
WARNING: This parameter in󰈢uences
the protective functions.
Please be aware that if "SyA. voltage
monitoring" (parameter 1771) is
con󰈡gured to "All" and the function
╚═▷ “4.3.1.10 System A Voltage
Increase” is used, that this function
only monitors "Phase - neutral".
2801 Mains settling time 2 0 to 9999 s
[20 s]
To end the emergency operation, the
monitored mains must be within the
con󰈡gured operating parameters
without interruption for the minimum
period of time set with this parameter
without interruption.
This parameter permits delaying the
switching of the load from the
generator to the mains.
The display indicates "Mains settling"
during this time.
Notes
The mains settling time input is
ignored in the application mode
A05
(L-GGBMCB). It is performed according
to the easYgen mains settling time
setting.
4.3.1.1 System A Operating Voltage / Frequency
General notes
If system A is
con󰈡gured and wired for mains, the system A operating voltage/frequency
parameters can be used to trigger mains failure conditions and activate an emergency
run.
The system A values must be within these ranges to synchronize the CBA.
• It is recommended to con󰈡gure the operating limits within the monitoring limits.
