12 - Ekip Synchrocheck
Ekip Synchrocheck is an accessory module that is used to control closing of an actuator when synchronism
conditions, programmable by the user, exist.
To actuate synchronism:
•
Ekip Synchrocheck and the internal sockets measure, respectively, the voltage on the external
contacts (external voltage) and on the internal contacts (internal voltage) of the actuator
•
Ekip Synchrocheck manages a closing contact
NOTES:
•
the actuator is described as a circuit-breaker in the following description and in the menus
• with a generator and the actuator being configured: Normally, the external voltage is that of
the grid and the internal voltage is that of the generator
IMPORTANT: only one Ekip Synchrocheck can be installed on each CB
Mode
The module operates in two modes, configurable by the user (manual-mode configuration) or managed
automatically by the unit (automatic-mode configuration).
Conditions Description
Busbar active
Operation with external voltage other than zero:
• synchronism search starts if the external voltage is (0.5 Un by default) or
more, for at least (1 s by default)
• synchronism is considered to have been reached if the differences between
RMS values and frequencies and the voltage phases are (0.12 Un, 0.1 Hz, and
50° by default) or less
Dead busbar and
configuration:
Normal
Operation with one of the voltages nil:
• synchronism search starts if the internal voltage is (0.5 Un by default) or
more, for at least (1 s by default)
• synchronism is considered to have been reached if the external voltage is (0.2
Un by default) or less, for at least (1 s by default)
NOTE: with dead busbar and configuration: Reversed, the roles of the internal and external
voltages are reversed
Synchronism signal:
• is activated and maintained, after synchronism has been reached, for at least 0.2 s
• is deactivated when synchronism ends or the circuit-breaker is opened (with condition:
Evaluate
CB status
= enabled) or communication with Ekip Touch is interrupted
Additional functions
Certain options can be remotely configured in the synchronism conditions described above:
• the open circuit-breaker condition can be added (disabled by default)
• removal of the frequency and phase controls can be disabled
IMPORTANT: to be able to disable the frequency and phase controls, first make sure that
the required frequency and phase correspondence between external and internal contacts
already exists
