51 - Ekip Signalling 3T
Ekip Signalling 3T is a signalling accessory that enables:
three analogue inputs for temperature sensors PT1000 (2-wire) to be enabled
one analogue input for 4-20mA current loops to be enabled
The measurements supplied by the module can be combined with different control thresholds,
which are useful for configuring alarm and status signals and programmable commands.
To connect Ekip Signalling 3T to Ekip Touch, the Ekip Cartridge (page 129) and Ekip Supply
(page 130) accessories are required.
Ekip Touch 2 can be configured with two different 3T modules: Ekip Signalling 3T-1 and Ekip
Signalling 3T-2.
The modules are identical in terms of characteristics and installation methods, except for: display
menus, cabling and addresses for system communication that are specific to each model.
NOTE: unless specified, the information shown in the following chapter is valid for both
the models
The two modules can be fitted simultaneously on the same circuit-breaker to increase the
possibility of measuring and controlling the plant.
IMPORTANT: Each circuit-breaker can fit just one module by type; configuration
with two modules of the same model is not permitted (e.g.: two Ekip Signalling
3T-1 modules)
Consult
the electrical diagrams for 1SDM000068R0001 for terminal references.
the instruction sheets 1SDH002009A1503 to connect the module to Ekip Supply and
Ekip Touch.
For the PT1000 sensors, use insulated cables for temperature sensors like PENTRONIC
TEC/SITW-24F (TX type) or the like, with maximum length of three metres.
For 4-20mA current loops sensor, use cables that are suitable and compatible with the work
environment in which the 4-20mA current sensor is used, with a maximum length of three metres.
IMPORTANT: The inputs are not insulated: regardless of the plant voltage, the
customer must ensure the insulation between each input and between inputs
and supply of the Ekip Supply module on the basis of the application and
network.
For applications in low voltage plants, ABB suggests using a dedicated external
insulated PT1000 sensor. This can be ordered using the 1SDA085695R1 code
and is provided with a nut and screw for use on a bar and is compatible with the
dielectric strength and insulation levels specified in standard IEC 60947-2 (Ui=
1000 V, Uimp= 12 kV).
Ekip Signalling 3T is supplied directly by the Ekip Supply module to which it is connected.
NOTE: in case of absence of an auxiliary supply the communication between the trip
unit and the module is interrupted
