LEDs Description
Power
Signals the on status and correct communication with Ekip Touch:
• off: module off
• on steady or flashing synchronized with the Power led of Ekip Touch: module on
and communication with Trip unit present, flashing not synchronized with the Power
led of Ekip Touch (two fast flashes per second): module on and communication with
Trip unit absent
O SC
Indicate the status of the contacts of each output:
• off: contact open
• on: contact closed
NOTE : The LED shows the output status: it indicates synchronization OK or
KO, depending on the contact rest configuration (normally open or closed)
Configurations via menu The specific configuration area will activate in the
Advanced
-
Synchrocheck
menu if the
Ekip Synchrocheck
module is detected correctly by Ekip Touch.
Parameter Description Default
Enable
Activates/deactivates the protection and its availability in the parameters
menu
Off
Dead bar option On = busbar activated; Off = dead busbar present Off
Udead
Threshold
(1)(2)
Maximum external voltage (with dead busbar and configuration: Normal
(2)
is the first synchronism condition)
The value is given as both absolute value (Volts) and relative value (Un)
and can be set within the range: 0.02 Un to 2 Un, in 0.001 Un steps
0.2 Un
Ulive
Threshold
(2)(3)
Minimum voltage for starting monitoring of external voltage (with busbar
activated) or internal voltage (with dead busbar and
Normal configuration)
The value is given as both absolute value (Volts) and relative value (Un)
and can be set within the range: 0.5 Un to 1.1 Un, in 0.001 Un steps
0.5 Un
Stability Time
Minimum time within which the Ulive Threshold condition must be
obtained in order to activate voltage monitoring
The value is given in seconds and can be set within the range: 100 ms to
30 s, in 1 ms steps
1 s
Delta Voltage
Maximum difference between internal and external voltage (first
synchronism condition)
The value is given as both absolute value (Volts) and relative value (Un)
and can be set within the range: 0.02 Un to 0.12 Un, in 0.001 Un steps
0.12 Un
Delta frequency
(4)
Maximum difference between internal and external frequency (second
synchronism condition)
The value is given in Hertz and can be set within the range: 0.1 Hz to 1
Hz in 0.1 Hz steps
0.1 Hz
Delta phase (4)
Maximum difference between internal and external phase (third
synchronism condition)
The value is given in degrees and can be set within the range: 5° to 50° in
5° steps
50 °
Dead bar
configuration
With dead busbar and generator:
• Reversed =
Ekip Synchrocheck /external contacts connected to the
generator
• Normal =
Ekip Synchrocheck /external contacts connected to the grid
Standard
Auto Live-dead
detect
Enables automatic synchronism control to be activated:
• Manual = Ekip Touch considers the
Dead bar option parameter
• Automatic = Ekip Touch automatically assesses the configuration to be
actuated between the dead busbar and active busbar
Manual
Auto Deadbar
detect
Configuration for detecting dead busbar:
•
Manual = Ekip Touch considers the Dead bar configuration parameter
• Automatic = Ekip Touch automatically assesses the configuration to be
actuated between: Reversed and Normal
Manual
Primary voltage
Rated voltage Un of installation; the value is given as absolute value
(Volts) and can be set within the range: 100 V to 1150 V in variable steps.
100 V
