LEDs Description
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
Power
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
Indicate the status of the contacts of each output:
• off: contact open
O SC • 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)
module is detected correctly by Ekip Touch.
Parameter Description
Activates/deactivates the protection and its availability in the parameters
Enable
menu
Dead bar option On = busbar activated; Off = dead busbar present
Maximum external voltage (with dead busbar and configuration: Normal
Udead is the first synchronism condition)
The value is given as both absolute value (Volts) and relative value (Un)
Threshold
(1)(2)
and can be set within the range: 0.02 Un to 2 Un, in 0.001 Un steps
Minimum voltage for starting monitoring of external voltage (with busbar
Ulive activated) or internal voltage (with dead busbar and Normal configuration)
Threshold The value is given as both absolute value (Volts) and relative value (Un)
(2)(3)
and can be set within the range: 0.5 Un to 1.1 Un, in 0.001 Un steps
Minimum time within which the Ulive Threshold condition must be
obtained in order to activate voltage monitoring
Stability Time
The value is given in seconds and can be set within the range: 100 ms to
30 s, in 1 ms steps
Maximum difference between internal and external voltage (first
synchronism condition)
Delta Voltage
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
Maximum difference between internal and external frequency (second
synchronism condition)
Delta frequency
(4)
The value is given in Hertz and can be set within the range: 0.1 Hz to 1
Hz in 0.1 Hz steps
Maximum difference between internal and external phase (third
synchronism condition)
Delta phase
(4)
The value is given in degrees and can be set within the range: 5° to 50° in
5° steps
With dead busbar and generator:
Dead bar • Reversed = Ekip Synchrocheck/external contacts connected to the
configuration generator
• Normal = Ekip Synchrocheck/external contacts connected to the grid
Enables automatic synchronism control to be activated:
Auto Live-dead • Manual = Ekip Touch considers the Dead bar option parameter
• Automatic = Ekip Touch automatically assesses the configuration to be
detect
actuated between the dead busbar and active busbar
Configuration for detecting dead busbar:
Auto Deadbar • Manual = Ekip Touch considers the Dead bar configuration parameter
detect • Automatic = Ekip Touch automatically assesses the configuration to be
actuated between: Reversed and Normal
Rated voltage Un of installation; the value is given as absolute value
Primary voltage
(Volts) and can be set within the range: 100 V to 1150 V in variable steps.
