5 - Frequency protections
List
The Frequency protections, available by default for Ekip Hi-Touch, Ekip G Touch, Ekip G-Hi Touch models
and configurable in the remaining models as additional SW package, are:
Name Type of protection Page
UF Minimum frequency 72
OF Maximum frequency 73
UF2
(1)
Minimum frequency 73
OF2
(1)
Maximum frequency 74
(1)
protections UF2 and OF2 are not available by default with Ekip G Touch. However, they can be
integrated by requesting the relative SW package
UF Protection
Function
The protection sends a TRIP command if the grid frequency read by the unit drops below threshold f12
for longer than t12.
The protection excludes itself if the maximum value of the line-to-line voltage is less than 30 V.
To check and simulate the trip times in relation to all the parameters, please consult:
• summary table of the protections with the operating characteristics (page 96)
• the graph with trip curve (page 108)
Parameters
Parameter Description Default
Enable
Activates/deactivates the protection and its availability in the
parameters menu
OFF
Trip Enable
Activates/deactivates transmission of the open command: if
disabled, the alarm and exceedance of protection time are only
managed as information
OFF
Threshold f12
Establishes the value that activates the protection.
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 Fn in 0.001
Fn steps
0,9 Fn
Time t12
This is the trip time of the protection; the value is given in
seconds and can be set within a range: 0.06 s to 300 s, in 0.01 s
steps
3 s
Limitations and additional functions
The block functions can also be accessed by means of the service connector (via Ekip Connect) or by
connection to the system bus (page 86).
