Parameter Description Default
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
(V) and can be set within the range: 100 V to 1150 V in variable steps.
100 V
Secondary voltage
Secondary voltage of the transformer; the value is given as absolute
value (V) and can be set within the range: 100 V to 120 V in variable
steps.
100 V
Concatenated Ref
Line-to-line voltage entering the module among the 3 installation
voltages
U12
Contact Type
Defines the rest status of the contact with synchronism not present
between: open (NO) and closed (NC)
NO
(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 ≤ 220 V)
• 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
communication:
Parameter Description Default
Frequency
check
Activates (ON) or deactivates (OFF) frequency control for synchronism
assessment
ON
Phase check
Activates (ON) or deactivates (OFF) phase control for synchronism
assessment
ON
Evaluate CB
status
Activates (YES) or deactivates (NO) circuit-breaker open status control for
synchronism assessment
NOTE:
fourth synchronism condition with busbar active; second
synchronism condition with dead busbar
NO
Minimum
matching
time
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
NOTE:
this is not a synchronism condition, but a parameter allowing
a 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)
100 ms
