Description
2227 Voltage restraint
monitoring 4 Yes The control provides voltage
restrained inverse time
overcurrent monitoring.
For general information about
voltage restrained monitoring
refer to
╚═▷ “4.5.1.4.3 Generator
Voltage Restrained Overcurrent
Monitoring - ANSI #51V”
.
[No] Voltage restrained monitoring is
disabled.
4031 Alarm class 2 Class A, Class B, Class C, Class D,
Class E, Class F , Control
[Class F]
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”
4032 Self acknowledge 2 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.
The alarm must be acknowledged
and reset by manually pressing
the appropriate buttons or by
activating the LogicsManager
output "External
acknowledgment" (via a discrete
input or via an interface).
4033 Enabled 2 [Always] Monitoring for this fault condition
is continuously enabled.
87.70 LM:Eng.mon Monitoring for fault conditions is
not performed until engine
monitoring is enabled. This is
determined through the
LogicsManager equation "Release
engine monitoring".
For xx = 1 to 32:
96.{xx}
LM: Flag{xx}
The monitoring is executed, if the
LogicsManager "Flag {xx}" is
TRUE.
Example:
96.01 LM: Flag 1, 96.02 LM: Flag
2, ..., 96.32 LM: Flag 32

General Notes
This function is an add-on to the over current monitoring and decreases the activation
limit dependent on the amount of voltage dip. Especially in near to generator located
