Summary Page The summary page is activated in the presence of the module Ekip Synchrocheck; access is
possible as for the other summary pages (page 24).
In this page, the measures are:
Information In the About-Modules menu, the specific menu of the module is available, which contains the
serial number and the version of the module
Remote From the service connector (via Ekip Connect) or with a system bus communication, additional
information information is available on the version and the status of the module: HW and Boot version, CRC
status (correctness of SW in the module).

Description

Busbar active = with automatic detection of the operating mode and operation
with busbar active, or with synchronism function not enabled

Dead busbar = with automatic detection of the operating mode and operation with
dead busbar

--- = Measurement not available (e.g.: because of manual detection of operating
mode)

VintVext = Internal voltage less than or the same as the external voltage

Vin>Vext = Internal voltage greater than the external voltage

--- = Measurement not available (e.g.: because of disabled synchronism or direct
voltage or less than 1 V)

fintfext = Internal frequency less than or the same as the external frequency

fin>fext = internal frequency greater than the external frequency

--- = Measurement not available (e.g.: because of disabled synchronism, or
operation with dead busbar, or frequencies outside measurement range)
NOTES:
(1) the measurement accuracy of the voltage difference is ± 10 %, unless the
parameter value is 0.02 Un, in which case accuracy is ± 20 %
(2) the characteristics of voltage and frequency measurements coincide with those
declared on internal inputs (page 96)

V int: voltage read by Ekip Touch

f int: frequency read by Ekip Touch

Δᶲ: phase difference

SYNC: synchronization status
