4.3 Ekip Signalling 2K -module
The Ekip Signalling 2K-3 is a signalling ac-
cessory module, which can be installed af-
terwards. On both switches there are al-
ready installed and used in the system
Ekip Signalling 2K-1 and 2K-2 -modules.
The Ekip Signalling 2K -module has:
• Two digital inputs, and two contacts for
output signals.
• A power status LED, and four signalling
LEDs (one LED for every input/output).
Notice
On ATS and Bypass, a maximum of three Ekip
Signalling 2K modules can be installed: one
2K-1, one 2K-2 (these both are factory in-
stalled and already used in the system) and
one 2K-3 (can be installed afterwards). These
modules differ by their name and label, and
have distinct wiring, but they are identical in
terms of their characteristics and manner of
installation.

4.3.2 Access from the display /
Ekip Signalling 2K -module
With modules energized, and Local Bus
enabled, the presence of the modules on
the module slot activates additional
menus on the display:
• In order to configure the inputs and out-
put contacts.
• To display information on the modules
and the state of inputs and outputs.
The following table illustrates the path for
accessing the configuration parameters
of the module from the display. Only Ekip
Signalling 2K-3 can be installed after-
wards; inputs
I 31/32 and outputs
O 31/32 are available for use .
