1SDH002031A1002 ECN000092998 Rev. B SACE Tmax XT2 – XT4 | 16950 - Ekip SynchrocheckEkip Synchrocheck is an accessory module that is used to control closing of an actuator if thereare synchronism conditions that are programmable by the user.In order to actuate the synchronism: Ekip Synchrocheck and internal jacks measure respectively the voltage on the externalcontacts (external voltage) and on the inner contacts (internal voltage) of the actuator Ekip Synchrocheck manages a closed contactNOTES: in the following description and in the menus the actuator is specified as a switchor CB with a generator and the actuator being configured: Normally, the external voltageis the network voltage and the internal voltage is the generator voltageIMPORTANT: Only one Ekip Synchrocheck can be installed on each CBTo connect Ekip Synchrocheck to Ekip Touch, the Ekip Cartridge (page 129) and Ekip Supply(page 130) accessories are required.Modes The module operates in two modes, configurable by user (in manual configuration) or managedautomatically by unit (in automatic configuration)Conditions DescriptionBusbar activeOperation with external voltage other than zero: the synchronism search is started up if the external voltage is lessthan or the same as a maximum (0.5 Un default), for a minimum time(1 s default). the synchronism is considered to be reached if the differencesbetween the RMS values, the frequencies and the voltage phases areless than or the same as a maximum (0.12 Un, 0.1 Hz, and 50 °default)Dead busbarandconfiguration:NormalOperation with one of the voltages nil: the synchronism search is started up if the internal voltage is less thanor the same as a minimum (0.5 Un default), for a minimum time (1 sdefault). the synchronism is considered to be reached if the external voltage isless than or the same as a maximum (0.2 Un default), for a minimumtime (1 s default).NOTE: with dead busbar and configuration: reverses the roles of internal and externalvoltages, which are reversedSynchronism signal: is activated and maintained after synchronism is reached and is kept active for at least 2 s is deactivated when the synchronism falls or the switch is open (with condition: EvaluateCB status= enabled) or the interrupted communication with Ekip TouchAdditionalfunctionsIn the above remote synchronism conditions, certain options can be configured: adding open switch condition (disabled by default) removing the frequency and phase controls can be disabledIMPORTANT: in order to be able to disable the frequency and phase controls,make sure that there is already the desired frequency and phase correspondencebetween external and internal contacts
