Ekip CI The menu activates in the presence of module Ekip CI, auxiliary power supply and local bus enabled.
The Autotest command is available in the menu; its selection activates the test of the leds and output contact
O61 in sequence:
1. Led reset and closing of contact O61 (if open)
2. Lighting up of all leds in sequence and successive switch-off
3. Opening of the O61 contact, switching on and off of the O61 led
4. Re-closing of O61 contact
IMPORTANT:
• the autotest sequence also includes transmission of the open command of the output
contact: the user is responsible for checking that it has opened correctly
• the test sequence always ends with the closing of the O61 contact, regardless of the
starting condition: verify that the change of status following the test does not create
problems in your installation.
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
Submenus

Consult the description of the putting into service procedure when checking the selectivity contacts (page
17).
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
