LED 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 displays the state of the output: it can indicate
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 (V) 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 (V) 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 (V) 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 °
