50 - Ekip Synchrocheck
Ekip Synchrocheck
is an accessory module that is used to control closing of an actuator if there
are 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 external
contacts (external voltage) and on the inner contacts (internal voltage) of the actuator
Ekip Synchrocheck
manages a closed contact
NOTES:
in the following description and in the menus the actuator is specified as a switch
or CB
with a generator and the actuator being configured:
Normally,
the external voltage
is the network voltage and the internal voltage is the generator voltage
IMPORTANT: Only one Ekip Synchrocheck can be installed on each CB
To 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 managed
automatically by unit (in automatic configuration)
Conditions
Description
Busbar active
Operation with external voltage other than zero:
the synchronism search is started up if the external voltage is less
than 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 differences
between the RMS values, the frequencies and the voltage phases are
less than or the same as a maximum (0.12 Un, 0.1 Hz, and 50 °
default)
Dead busbar
and
configuration:
Normal
Operation with one of the voltages nil:
the synchronism search is started up if the internal voltage is less than
or the same as a minimum (0.5 Un default), for a minimum time (1 s
default).
the synchronism is considered to be reached if the external voltage is
less than or the same as a maximum (0.2 Un default), for a minimum
time (1 s default).
NOTE:
with dead busbar and configuration:
reverses
the roles of internal and external
voltages, which are reversed
Synchronism 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:
Evaluate
CB status
= enabled) or the interrupted communication with Ekip Touch
Additional
functions
In 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 disabled
IMPORTANT: in order to be able to disable the frequency and phase controls,
make sure that there is already the desired frequency and phase correspondence
between external and internal contacts
