Interface the module has three signaling leds:

Figure 136
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)

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
Activates/deactivates the protection and its availability in the parameters
Enable Off

Dead bar option On = busbar activated; Off = dead busbar present Off
Maximum external voltage (with dead busbar and configuration: Normal
(2)
Udead T is the first synchronism condition) 0.2 Un
hreshold (1)(2) 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
Minimum voltage for starting monitoring of external voltage (with busbar
Ulive activated) or internal voltage (with dead busbar and Normal configuration) 0.5 Un
Threshold (2)(3) 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
Minimum time within which the Ulive Threshold condition must be
obtained in order to activate voltage monitoring
Stability Time 1 s

30 s, in 1 ms steps
Maximum difference between internal and external voltage (first
synchronism condition)
Delta Voltage 0.12 Un
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) 0.1 Hz
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) 50 °
The value is given in degrees and can be set within the range: 5° to 50° in
5° steps
