UP Protection
Function
If one or more active powers read by the unit falls below the P23 threshold for a time greater than
t23, the protection sends the TRIP command.
Protection is also active for negative active power (inverse), but is independent of RP protection
(inverse active power protection).
The protection automatically cuts out if the maximum line-to-line voltage value is still less than
30 V.
To verify and simulate the trip times based on all the parameters, see:
Protection summary table with the operating characteristics (page 79)
Chart with tripping curve (page 93)
Parameters
Parameter
Description
Default
Enable
Enables/disables protection and availability on menu of the
parameters
OFF
Trip Enable
Activates/deactivates the open command: if disabled, the alarm
and the lapsing of the protection time are managed only as
information
OFF
Threshold
P23
Defines the value that activates the protection.
The value is expressed both as an absolute value (kW) and as a
relative value (Sn), settable in a range:
0.1 Sn .. 1 Sn with 0.001 Sn step
1 Sn
Time t23
This is the trip time of the protection; the value is expressed in
seconds, which are settable in a range:
0.5 s .. 100 s, with 0.5 s step
1 s
StartUp
enable
Activates/deactivates the function and the availability on the menu
of the parameters
OFF
StartUp time
This is the time for which the threshold is disabled, calculated from
tripping of activation threshold
The value is expressed in seconds, which are settable in a range:
0.1 s .. 30 s, with 0.01 s step.
0.1 s
Constraints, limitations, and additional functions
From the service connector (with Ekip Connect) or with system bus communication it is also
possible to access the block functions, see page70.
