VS Warning A warning signal is activated if all three of the line-to-line voltages measured by the Trip unit are within the
window defined by the control thresholds for the set time.
The Protections-Advanced-Warnings menu includes the control threshold submenu in which the parameters
can be entered:
Parameter Description Default
Activates/deactivates monitoring of the parameters and their availability in
Enable Off
the menu
Defines whether the line-to-line voltages to be verified are those from the
internal sockets (Measurement module) or from Ekip Synchrocheck, if
Signal source present. Meas.
NOTE: if Ekip Synchrocheck is set, monitoring will refer to one single
voltage
Establishes the lower limit value of the control band, given as both absolute
Threshold
DOWN value (Volts) and relative value (Un), which can be set within the range: 0.5 0,9 Un
Un to 1 Un in 0.001 Un steps
Establishes the upper limit value of the control band, given as both absolute
Threshold UP value (Volts) and relative value (Un), which can be set within the range: 1 Un 1,1 Un
to 1.5 Un, in 0.001 Un steps
This is the monitoring time that activates the signal; the value is given in
Time 30 s
seconds and can be set within a range: 0.1 s to 900 s, in 0.1 s steps

FS Warning A warning signal is activated if the frequency measured by the Trip unit is within the window defined by the
control thresholds for the set time.
The Protections-Advanced-Warnings menu includes the control threshold submenu in which the parameters
can be entered:
Parameter Description Default
Activates/deactivates monitoring of the parameters and their availability in
Enable Off
the menu
Defines whether the line-to-line voltages to be verified are those from the
internal sockets (Measurement module) or from Ekip Synchrocheck, if
Signal source present. Meas.
NOTE: if Ekip Synchrocheck is set, monitoring will refer to one single
voltage
Establishes the lower limit value of the control band, given as both absolute
Threshold value (Hertz) and relative value (Fn), which can be set within the range: 0.9 0,998 Fn
DOWN
Fn to 1 Fn in 0.001 Fn steps
Establishes the lower limit value of the control band, given as both absolute
Threshold UP value (Hertz) and relative value (Fn), which can be set within the range: 1 Fn 1,002 Fn
to 1.1 Fn in 0.001 Fn steps
This is the monitoring time that activates the signal; the value is given in
Time 30 s
seconds and can be set within the range: 0.1 s to 900 s, in 0.1 s steps

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 will be activated (no TRIP).
The Protections-Advanced-Warnings-F W Warnings menu includes the control threshold submenu in which
the parameters can be entered:

Parameter Description Default
Activates/deactivates the control threshold of the parameters and their
Enable Off
availability in the menu
Defines whether frequency monitoring is performed after the measured
Direction Down
sequence has dropped (Down) or been exceeded (Up)
Establishes the value that activates the alarm.
Threshold The value is given as both absolute value (Hertz) and relative value (Fn) and 3 Fn
can be set within the range: 0.9 Fn to 1.1 Fn in 0.001 Fn steps
