3 - Ekip Signalling 4K

Ekip Signalling 4K is an accessory signaling module allowing programmable inputs/outputs to be managed.
This module has:
• four outputs and relative state led: O 01, O 02, O 03, O 04
• four digital inputs and relative state led: I 01, I 02, I 03, I 04
• a Power led with the startup status of the module

The module can be installed on Emax 2 E2.2-E4.2-E6.2 circuit-breakers equipped with Ekip Touch trip unit.

NOTE: Ekip Signalling 4K can be installed on circuit-breakers in which AUX 6Q contacts are
not present

Connections The module connects directly to the Mainboard, in the dedicated slot on the left-hand side of the display;
the outputs and inputs of the module can be accessed from the upper terminal box of the circuit-breaker.
To connect the module to Ekip Touch, please consult document 1SDH001000r0516.
For references about the connection and terminals, please consult document 1SDM000091r0001.

Power supply Ekip Signalling 4K functions with Ekip Touch energized by auxiliary supply, with Ekip Supply or direct power
supply, or via the Measurement enabler with voltage sockets module.
The Power led comes on when the module is activated and functioning.
NOTE: when the module is off, the output contacts are always in the open position and the
state of the inputs is not valid

Output Each output consists of two contacts (O 01: K3-K7; O 02: K4-K8; O 03: K5-K9; O 04: K6-K10), isolated
from the trip unit and other outputs, which have two physical states (contacts open or closed) and provide
the following electrical characteristics:

Characteristics Maximum limit (1)
Maximum switchable voltage 150 VDC / 250 VAC.
2 A @ 30 VDC, 0,8 A @ 50 VDC, 0,2 A @ 150 VDC,
Breaking capacity
4A @ 250 VAC
Dielectric strength between open contacts 1000 V AC (1 minute @ 50 Hz).
Dielectric strength between each contact and coil 1000 V AC (1 minute @ 50 Hz).

(1) data relating to a resistive load

All the outputs are independent and can be programmed so as to activate when one or more events occur
(see Menu on page 187).

Input Each input consists of two contacts (I 01: H1-HC; I 02: H2-HC; I 03: H3-HC; I 04: H4-HC) and has two
physical states: open circuit (> 100 kΩ) and short circuit (< 50 Ω)
All the inputs are independent and can be programmed so that an action or signaling are executed at the time
of a specific change of state (see Menu on page 188).
Ekip Touch interprets the state of each input differently, on the basis of the electrical condition detected and
the configuration of the contact programmed via the (polarity) menu:
Electrical condition Contact configuration (polarity) State detected
Active open ON
Circuit open
Active closed OFF
Active open OFF
Short-circuit
Active closed ON
