Parameter Description Default
With dead busbar and generator:
Dead bar • Reversed = Ekip Synchrocheck/external contacts connected to the Standard
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
detect • Automatic = Ekip Touch automatically assesses the configuration to be Manual
actuated between the dead busbar and active busbar
Configuration for detecting dead busbar:
Auto Deadbar • Manual = Ekip Touch considers the Dead bar configuration parameter Manual
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 100 V
(Volts) and can be set within the range: 100 V to 1150 V in variable steps.
Secondary voltage of the transformer; the value is given as absolute value
Secondary voltage 100 V
(Volts) and can be set within the range: 100 V to 120 V in variable steps.
Concatenated Ref Line-to-line voltage entering the module among the 3 installation voltages U12
Defines the rest status of the contact with synchronism not present
Contact Type NO
between: open (NO) and closed (NC)
(1) parameter not available with busbar active and Auto deadbar detect= Manual
(2) with dead busbar and configuration: Reversed, the roles of the internal and external voltages are reversed
(3) 10% hysteresis is applied to the minimum voltage condition: once reached, the condition is lost if the
voltage drops below 90% of the set limit
(4) parameter not available with dead busbar and Auto deadbar detect= Manual

NOTE: all the thresholds have ±10% tolerance with the exception of:
• Voltage Delta; the tolerance is the higher value between: ±10% of the set threshold and 0.5%
Un (with Un > 220 V) or 1% Un (with Un ≤ 220V)
• Frequency Delta; the tolerance is the higher value between ±10% of the set threshold and 0.02
Hz

Remote configurations Additional parameters can be accessed via the service connector (via Ekip Connect) or via a system bus

status NOTE: fourth synchronism condition with busbar active; second NO
synchronism condition with dead busbar
With active busbar, minimum time within which the Delta Phase condition must
be obtained
The value is given in seconds and can be set within the range: 100 ms to 3 s,
in 10 ms steps
Minimum NOTE: this is not a synchronism condition, but a parameter allowing a 100 ms
matching time
discrimination to be made between correct and incorrect combinations of
the Delta Frequency and Delta Phase conditions. Owing to worst case
latencies, the time that effectively elapses before synchronism is
recognized may be longer than the set time (approx. 20 ms)
