Dead Bus Config Reversed, Standard
(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.

Minimum voltage in order to start up monitoring of the voltages
• With Bar live, external under-voltage.
0.5 Un
• With Bar dead, and "Standard" configuration, internal under-

With Bar live, 3
50 °
between internal and external phase.
With the Bar live, the minimum time within which the "Delta Phase"
condition must be satisfied: this is not a synchronism condition,
100 ms but a parameter that allows you to discriminate between correct
combinations, rather than the "Delta Frequency" and "Delta Phase"
conditions.
• Off = Bar live.
Off
• On = Bar dead.
With Bar live, "Delta Frequency" condition:
ON • OFF = Disabled.
• ON = Enabled.
With Bar live, "Delta Phase" condition:
ON • OFF = Disabled.
• ON = Enabled.
Circuit-breaker open condition (With Bar live 4

NO
• NO = Disabled.
• YES = Enabled.
With Bar dead, and generator:
• Reversed = Ekip Synchrocheck/external contacts connected to

• Standard = Ekip Synchrocheck/external contacts connected to
the network.
