The following table illustrates the configuration parameters of the synchronism function:
Parameter Values Default Description
Enable Off, On Off
• Off = Function disabled.
• On = Function enabled
Delta U Threshold
0.02...0,12 Un
in steps of 0.001 Un
0.12 Un
With Bar live, 1
a
synchronism condition: maximum difference
between internal and external voltage.
U Dead Threshold
0.05...0.20 Un
in steps of 0.001 Un
0.2 Un
With Bar dead, and "Standard" configuration, 1
a

condition: maximum external voltage

U Live Threshold
0.5...1.1 Un
in steps of 0.001 Un
0.5 Un
Minimum voltage in order to start up monitoring of the voltages

Delta Frequency
0.1...1.0 Hz
in steps of 0.1 Hz

With Bar live, 2
a
synchronism condition: maximum difference

100 ms
With the Bar live, the minimum time within which the “Delta Phase”
condition must be satisfied: this is not a synchronism condition,
but a parameter that allows you to discriminate between correct
combinations, rather than the “Delta Frequency” and “Delta Phase”
conditions.
Dead Bus Option Off, On Off
• Off = Bar live.
• On = Bar dead.
Frequency Check
(3) (4)
ON, OFF ON
With Bar live, “Delta Frequency” condition:
• OFF = Disabled.
• ON = Enabled.
Phase Check
(3) (4)
ON, OFF ON
With Bar live, “Delta Phase” condition:
• OFF = Disabled.
• ON = Enabled.
evaluate CB status
(3)
NO, YES NO
Circuit-breaker open condition (With Bar live 4
a
synchronism
condition, With Bar dead 2
a
synchronism condition):
• NO = Disabled.
• YES = Enabled.
Dead Bus Config Reversed, Standard Standard
With Bar dead, and generator:
• Reversed = Ekip Synchrocheck/external contacts connected to
the generator
(1)
.
• Standard = Ekip Synchrocheck/external contacts connected to
the network.
(1)
With Bar dead, and "Reversed" configuration, the roles of the internal and external voltages are inverted.
(2)
On the condition of minimum voltage, a hysteresis of 10% is applied: once reached, the condition is lost if the voltage drops below 90% of the set
limit.
(3)
Parameter available only with the Ekip Connect application.
(4)
If the Frequency Check is disabled ("OFF"), the Phase Check is also Off, but not vice versa.
