Configurations
on menu
If the Ekip Synchrocheck module is detected correctly by Ekip Touch the specific configuration
area is activated in the Advanced-Synchrocheck menu.
Parameter
Description
Default
Activate
Enables/disables protection and availability on menu of the parameters
Off
Dead bar
option
On= busbar active; Off= dead busbar present
Off
Udead
Threshold
(1) (2)
Maximum external voltage (with dead busbar and configuration :
Normal
(2)
is the first synchronism condition )
The value is expressed both as an absolute value (Volt) and as a relative
value (Un), settable in a range: 0.02 Un .. 2 Un with 0.001 Un step
0.2 Un
Threshold Ulive
(2) (3)
Minimum voltage for starting monitoring of external voltage (with busbar
active) or internal voltage (with dead busbar and Normal configuration)
The value is expressed both as an absolute value (Volt) and as a relative
value (Un), settable in a range: 0.5 Un .. 1.1 Un with 0.001 Un step
0.5 Un
Stability time
Minimum time within which the Ulive Threshold condition must be fulfilled
to start up voltage monitoring.
The value is expressed in seconds, settable in a range: 100 ms - 30 s
with 1 ms step
1 s
Delta Voltage
Maximum difference between internal and external voltage (first
synchronism condition)
The value is expressed both as an absolute value (Volt) and as a relative
value (Un), settable in a range: 0.02 Un .. 0.12 Un with 0.001 Un step
0.12 Un
Delta
Frequency
(4)
Maximum difference between internal and external frequency (second
synchronism condition)
The value is expressed in Hertz, which is settable in a range:
0.1 Hz .. 1 Hz with 0.1 Hz step
0.1 Hz
Delta Phase
(4)
Maximum difference between internal and external phase (third
synchronism condition)
The value is expressed in degrees, which are settable in a range:
5 ° .. 50 ° with 5 ° step
50 °
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
network
Normal
Auto Live-dead
detect
Enables automatic synchronism control to be activated:
 Manual = Ekip Touch considers the parameter Dead bar option
 Automatic = Ekip Touch automatically evaluates the configuration to
be actuated between the dead busbar and the active busbar
Manual
Auto Deadbar
detect
Configuration for detecting dead busbar:
 Manual = Trip unit considers the Dead Bar Configuration parameter
 Automatic = Ekip Touch automatically evaluates the configuration to
be actuated between: Reversed and Normal
Manual
Primary voltage
Rated voltage Un of plant; the value is expressed as an absolute value
(Volt), settable in a range: 100 V .. 1150 V with variable step
100 V
Secondary
voltage
Secondary voltage of the transformer; the value is expressed as an
absolute value (Volt), settable in a range:
100 V .. 120 V with variable step
100 V
Concatenated
Ref
Network voltage entering module between the 3 plant voltages
U12
Contact Type
Defines the rest status of the contact with non-present synchronism
between: open (NO) and closed (NC)
NO
NOTES:
(1) parameter not available with busbar active and Auto Live-dead detect = Manual
(2) with dead busbar and configuration= Reversed, reverses the roles of internal and
external voltages
(3) to the minimum voltage condition, 10% hysteresis is applied: once it is reached,
the condition is lost if voltage falls below 90% of the set limit
(4) parameter not available with dead busbar and Auto Live-dead detect = Manual
