14 - 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

Accessories Ekip Cartridge and Ekip Supply are required in order to connect Ekip Synchrocheck to Ekip
Touch (page 130, 131).

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
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)
Busbar active
• 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
Operation with one of the voltages nil:
Dead busbar and • synchronism search starts if the internal voltage is (0.5 Un by default) or
configuration: more, for at least (1 s by default)
Normal • 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

Connections For references about the connection and terminals, please consult document 1SdM000005A1001; use
AWG 22-16 cables with 1.4 mm maximum outer diameter for the external cabling.
To connect the module to Ekip Supply and Ekip Cartridge, please consult document 1SdH002009A1503.
