Ekip Signalling 4K The menu activates in the presence of module Ekip Signalling 2K and auxiliary power supply.
The Autotest command is available in the menu; it activates the automatic output test sequence (contacts
and leds) and provides for the following operations:
• Opening of the output contacts and switching off of output leds
• Closing in sequence of the four output contacts and switching on of the relative leds
• Reset initial conditions
IMPORTANT: the Autotest command closes the contacts regardless of the configuration
set by the user: the user is responsible for making the devices connected to the
modules secure, checking that the contacts have closed properly and that the leds
have come on

Ekip Signalling 2K The menu activates in the presence of module Ekip Signalling 2K, auxiliary power supply and local bus
enabled.
NOTE: a menu is available for each Ekip Signalling 2K module present, up to a maximum of
three
The Autotest command is available in each submenu; it activates the automatic output test (Contacts and
leds), input test (leds) and provides for the following operations:
1. Resetting of output contacts (= open) and leds (= off).
2. Lighting up of all leds in sequence (output and input)
3. Closing and switch-off in sequence of the two output contacts while the relative leds come on.
4. Reset initial conditions
IMPORTANT: the Autotest command closes the contacts regardless of the configuration
set by the user: the user is responsible for making the devices connected to the
Ekip Signalling 2K modules secure, checking that the contacts have closed properly
and that the leds have come on

ZoneSelectivity The menu has one or two sections, visibility of which depends on the protections available and enabled:
Submenus Reference selectivity Outputs/Inputs managed
S Selectivity S, S2, D (Forward) SZi (DFi), SZo (DFo)
G Selectivity G, Gext, MDGF, D (Backward) GZi (DBi), GZo (DBo)

Each submenu has three fields for checking selectivity inputs and outputs:

Field Description
Input Provides the status of the selectivity input (On/Off)
Force output Selectivity output activated
Force Output Selectivity output deactivated

Consult the description of the putting into service procedure when checking the selectivity contacts in the
manuals 1SDH000999r1002 and 1SDH001000r1002.

RC test The command is available in the presence of Rating plug Rc and Rc toroid.
Selection of the command accesses a window containing the protection settings and test instructions:
1. Press the iTEST button to send a test signal to the toroid.
2. The toroid sends Ekip Touch a signal as though it had measured an alarm current.
3. Ekip Touch sends a TRIP command.
IMPORTANT: the command sends a signal to the Rc toroid and concludes with a TRIP
command: the user is responsible for checking that the initial connections are
correct (of the toroid and power supplies of the unit) and that TRIP is accomplished
