FS Warning
If the frequency measured by the Trip unit is within the window defined by the control thresholds
for the time set, the warning signal is activated.
The control threshold submenu is available in the
Protections-Advanced-Warnings
menu, where
the following parameters can be set:
Parameter
Description
Default
Enable
Enable/disable the control and the availability of the parameters in
the menu
OFF
Signal
source
Defines whether the line-to-line voltages to be checked are those
from the internal sockets (Measuring) or from the Ekip
Synchrocheck, if present.
NOTE: by setting Ekip Synchrocheck the control refers to
a single voltage
Meas.
DOWN
Threshold
Defines the lower value of the control band, expressed both in an
absolute value (Hertz) and a relative value (Fn), which can be set in
a range: 0.9 Fn .. 1 Fn with 0.001 Fn steps
0.998 Fn
UP
Threshold
Defines the lower value of the control band, expressed both in an
absolute value (Hertz) and a relative value (Fn), which can be set in
a range: 1 Fn .. 1.1 Fn with 0.001 Fn steps
1.002 Fn
Time
The voltage control time to activate the signal. The value is
expressed in seconds, which can be set in a range:
0.1 s .. 900 s, with 0.1 s steps
30 s
F W1 Warning
If the frequency measured by the Trip unit exceeds or falls below the threshold (depending on
the direction set), the corresponding alarm is activated (TRIP not envisaged).
The control threshold submenu is available in the
Protections-Advanced-Warnings-F W Warning
menu, where the following parameters can be set:
Parameter
Description
Default
Enable
Enable/disable the control threshold and the availability of the
parameters in the menu
OFF
Direction
Defines whether the frequency control is performed as a result of
drops (Down) or increases (Up) of the measured sequence
Down
Threshold
Defines the value that triggers the alarm.
The value is expressed both in an absolute value (Hertz) and a
relative value (Fn), which can be set in a range:
0.9 Fn .. 1.1 Fn with 0.001 Fn steps
1 Fn
