Parameter Description Default
StartUp
enable
Activates/deactivates the function and availability of the associated
parameters on the display
OFF
StartUp
Threshold
Fw
(2)
Protection threshold valid during Startup time, in the conditions in
which the function is activated and with forward current direction
(2)
.
The value is given as both absolute value (amperes) and relative value
(In) and can be set within the range: 0.6 In to 10 In, in 0.1 In steps
2 In
StartUp
Threshold
Bw
(2)
Protection threshold valid during Startup time, in the conditions in
which the function is activated and with backward current direction.
The value is given as both absolute value (amperes) and relative value
(In) and can be set within the range: 0.6 In to 10 In, in 0.1 In steps
2 In
StartUp Time
(2)
This is the time for which the StartUp threshold remains activated and
is calculated from the moment the activation Threshold is exceeded
The value is given in seconds and can be set within the range: 0.1 s to
30 s, in 0.01 s steps
0.1 s
Direction Min
Angle
Ekip Touch calculates the phase displacement angle between active
and apparent power measured: when phase displacement exceeds
the set Direction Min Angle parameter, the unit considers the fault
direction to have been identified. The value is given in degrees and can
be set within a range of 15 values from 3.6° to 69.6°
3,6 °

Limitations and additional functions
the functions blocking the type of selectivity and the
Trip only Forward
and
Trip Only Backward
parameters
can also be accessed by means of the service connector (via Ekip Connect) or communication via system
bus (page 86).
Notes
• activation of D directional protection automatically activates the alarm that monitors phase
sequence (which can also be excluded and activated in the manual mode): note how, in the case
of a cyclic sequence of phases that differs from the set value, in the event of a fault the directional
protection inverts the reference direction with respect to the expected direction; details of the
phase sequence protection are available on page 67
• in the case of small overcurrents, the behavior of the directional protection is influenced by the
type of load: to prevent the direction of the fault current from being incorrectly interpreted in the
case of capacitive loads, it is advisable for the setting of that protection to be made on the basis
of real fault conditions and not overloads
