Woodward easYgen-3000XT Series, Manual, Page: 508 / 1205

The average is set to "Mains rated voltage" (parameter ╚═▷ 1768 ) if:
• Frequency is not in the operating range OR •
• Monitoring (parameter
╚═▷ 8806 ) is "Off" OR •
• Monitoring is "Delayed by engine speed" (parameter
╚═▷ 8833 ) OR •
• Monitoring is tripped AND the measured voltage is again in the operating range
•
Back synchronization is only possible if:
• The 10 minute average value is smaller than the defined limit AND •
• The actual measured value is inside the operating range AND
•
• The mains settling time is over
•

Description
8806 Monitoring 2 On Voltage increase monitoring is
carried out according to the
following parameters.
[Off] No monitoring is carried out.
8807 Limit 1 100 to 150%
[110%]
The percentage voltage value that
is to be monitored is defined here.
If the average voltage over 10
minutes is higher, the action
specified by the alarm class is
initiated.
Notes
This value refers to the "Mains
rated voltage" (parameter
╚═▷
1768 ).
8849 AND characteristics 2 On If the 10 minute voltage averages
of all phases exceed the limit, the
monitoring is tripping.
[Off] If the 10 minute voltage average
of at least one phase exceeds
the limit, the monitoring is
tripping.
8831 Alarm class 2 Class A, Class B, Class C, Class D,
Class E, Class F , Control
[Class B]
Each limit may be assigned an
independent alarm class that
specifies what action should be
taken when the limit is surpassed.
Notes
For additional information refer to
╚═▷ “9.5.4 Alarm Classes”
8832 Self acknowledge 4 [Yes] The control unit automatically
clears the alarm if the fault
condition is no longer detected.
No The control unit does not
automatically reset the alarm
when the fault condition is no
longer detected.
