11 - Ekip Signalling 2K

Ekip Signalling 2K is an accessory signaling module allowing programmable inputs/outputs to be managed.
This module has:
• two contacts for output signals and relative status led
• two digital inputs and relative status led
• a Power led with the startup status of the module

Models Three different Signalling 2K modules are available: Ekip Signalling 2K-1, Ekip Signalling 2K-2 and RELT - Ekip
Signalling 2K-3.
The modules are identical in terms of characteristics and installation methods, except for: display menus,
cabling and addresses for system communication, which are specific for each module.

NOTE: if different indications are not given, the information in the next chapter is valid for all
three models

Two of the three modules can be connected at the same time to Ekip Touch so as to expand the potential of
the unit (e.g. to increase the number of control outputs and inputs).
IMPORTANT: each Ekip Touch can be fitted with only one module per type. The
configuration with two or three modules of the same model is not allowed
(example: two Ekip Signalling 2K-1 modules)
RELT - Ekip Signalling 2K-3
The RELT - Ekip Signalling 2k-3 module has a dedicated command (RELT Wizard) for auto-programming
a set of trip unit parameters; The wizard ensures the activation of the 2I protection when the input of the
RELT – Ekip Signalling 2k-3 module active. In addition, the 2I is placed in local model and the RELT module’s
outputs are activated.
Below is a complete list of the parameters configured by the command:
Parameter Configuration from RELT Wizard command Page
2I Protection (1) On; Threshold I31 = 1,5 In 59
Delay = 100 ms; Activation = depentent function;
2I Protection Function 59, 89
Function = RELT - Ekip Signalling 2K-3 Input 1 (I31)
Input I31 (RELT - Ekip Polarity = active closed; Delay = 0,1 s 221, 222
Signalling 2K-3)
Output O31 and O32 Signal source = 2I protection active; Delay = 0 s; Contact
(RELT - Ekip Signalling 2K-3) type = NO; Self-latching = OFF; min Activation Time = 0 ms 222
SwitchOnLocal Function Function = 2I protection active; Delay = 0 s 89

(1) if Dual set is present, programming performed for both Set A and Set B
The RELT setup Wizard can be found in the 2I protection menu and also the first time the trip unit is switched
ON.
In the case that the wizard is not executed (or is rejected during the initial trip unit start up), the functionality
and the characteristic of the RELT – Ekip Signalling 2k-3 module will be as described in the following pages.
NOTE: The input is able to operate with a maximum input resistance of 25 Ohm. Wiring
distance limitation have to be calculated from this value. As example: considering an
AWG20 cable with 29.5 Ohm/km and a microswitch with a resistance of few milliohm (negligible
for the calculation) the limitation is: 25 (Ohm)/29.5 (Ohm/km)/2wires=0.423 km=423mt

Connections The module must be assembled in the first vacant slot of the terminal box after Ekip Supply, either on the
circuit-breaker (fixed version) or on the fixed part (withdrawable version).
For references about the connection and terminals, please consult document 1SDM000091r0001 and
1SDM000019A1002; use AWG 22-16 cables with 1.4 mm maximum outer diameter for the external cabling.
To connect the module to Ekip Touch, please consult document 1SDH001000r0524.
