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
Enable
Activates/deactivates monitoring of the parameters and their
availability in the menu
Off
Signal source
Defines whether the line-to-line voltages to be verified are those from
the internal sockets ( Measurement module) or from Ekip Synchrocheck ,
if present.
NOTE: if Ekip Synchrocheck is set, monitoring will refer to one
single voltage
Meas.
Threshold
DOWN
Establishes the lower value of the control band, given as both absolute
value (V) and relative value (Un), which can be set within the range: 0.5
Un to 1 Un in 0.001 Un steps
0,9 Un
Threshold UP
Establishes the upper value of the control band, given as both absolute
value (V) and relative value (Un), which can be set within the range: 1 Un
to 1.5 Un in 0.001 Un steps
1,1 Un
Time
This is the monitoring time that activates the signal; the value is given
in seconds and can be set within a range: 0.1 s to 900 s, in 0.1 s steps
30 s
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
Enable
Activates/deactivates monitoring of the parameters and their
availability in the menu
Off
Signal source
Defines whether the frequencies of the line-to-line voltages to be
verified are those from the internal sockets ( Measurement module) or
Ekip Synchrocheck , if present.
NOTE: if Ekip Synchrocheck is set, monitoring will refer to one
single voltage
Meas.
Threshold
DOWN
Establishes the lower limit value of the control band, given as both
absolute value (Hertz) and relative value (Fn), which can be set within
the range: 0.9 Fn to 1 Fn in 0.001 Fn steps
0,998 Fn
Threshold UP
Establishes the lower limit value of the control band, given as both
absolute value (Hertz) and relative value (Fn), which can be set within
the range: 1 Fn to 1.1 Fn in 0.001 Fn steps
1,002 Fn
Time
This is the monitoring time that activates the signal; the value is given
in seconds and can be set within the range: 0.1 s to 900 s, in 0.1 s steps
30 s
F W1 Warning
The F W1 Warning function activates the alarm (without commanding TRIP) if the frequency measured by
Ekip Touch exceeds or drops below the set threshold value (depending on the direction set).
The
Protections-Advanced menu includes the F W1 Warning submenu via which the following parameters
can be configured:
Parameter Description Default
Enable
Activates/deactivates the control threshold of the parameters and their
availability in the menu
Off
Direction
Defines whether frequency monitoring is performed after the
measured sequence has dropped (Down) or been exceeded (Up)
Down
Threshold
Establishes the value that activates the alarm.
The value is given as both absolute value (Hertz) and relative value (Fn)
and can be set within the range: 0.9 Fn to 1.1 Fn in 0.001 Fn steps
3 Fn
