Check accessories
The inspections to perform on the external accessories, if present, before putting into service are indicated
below:
Accessories Checks
External
modules
1. For all modules with terminal box: check connection to Ekip Supply in mechanical
seat of terminal box
For Ekip Signalling 10K and Ekip Multimeter, in the absence of Ekip Supply: check the
connection of the bus of the module (W3-W4) to Ekip supply
2. Power up Ekip Touch (and the external modules if there is a separate supply) and
make sure they are on
3. Check that the Local bus is enabled (Settings-Modules-Local Bus)
4. Check that the Power Led of each module is on like the Power Led of Ekip Touch
(steady or synchronous flash)
5. Check in the About-Modules menu to make sure that all installed modules are present
and that there are no alarms
External neutral
S.G.R. Toroid
Rc Toroid
1. Check the connection of the sensor to the terminal box and that the direction in
relation to the CB is correct
2. Power up the Trip unit and make sure it is on
3. For External neutral: check in the Settings-Circuit-breaker menu that Configuration=
3P + N; otherwise change the parameter
For S.G.R. Toroid and Rc Toroid: set presence and size in the Settings-Circuit-breaker-
Ground protection menu; protection parameters in the Protections or Advanced menus
4. Make sure there are no alarms
Zone selectivity
1. Check selectivity connections (between Ekip Touch and the other units) as shown in
circuit diagrams 1SDM000002A1001
2. Provide Ekip Touch with auxiliary power and make sure that CB status is: Open
3. Check that the protection of the selectivity concerned has been enabled (example: S
protection)
4. Select the Zone Selectivity menu and the submenu of the protection concerned;
follow the instructions in points 5, 6, 7 and 8 for each protection activated
NOTE: for selectivity D, consider submenu S for the Forward connections and G
for the Backward connections
Check Output:
5. Select the Force Output command and check, on the Trip unit connected to the Ekip
Touch output, that the status of its Input = ON
6. Select the Release Output command and check, on the Trip unit connected to the
Ekip Touch output, that the status of its Input = OFF
Check Input:
7. Select the Force Output command on the Trip unit connected to the Ekip Touch input
and check on Ekip Touch that the status of its Input = ON
8. Select the Release Output command on the Trip unit connected to the Ekip Touch
input and check on Ekip Touch that the status of its Input = OFF
Opening
and closing
actuators YO
and YC (remote
controlled) if
present
1. Make sure that actuators YO and YC are correctly cabled, as shown in circuit
diagrams 1SDM000002A1001
2. Set the circuit-breaker to the closed position
3. Provide Ekip Touch with auxiliary power and supply the actuators with rated voltage
4. Perform an opening test from the (Test-Test CB menu, Open CB) command and
check that the CB has switched
5. Repeat the test by imparting a close command (Close CB)
