15 - Ekip Signalling 3T
Ekip Signalling 3T
is a signaling accessory which enables the connection of:
• three analog inputs for PT1000 temperature sensors (2 wires): I42, I43, I44
• an analog input for 4-20mA current loop: I41
The measurements supplied by the module can be associated with different control threshold, useful for
configuring alarm signals, states and programmable commands.
Accessories
Ekip Cartridge
and
Ekip Supply
are required in order to connect
Ekip Signalling 3T
to Ekip Touch
Models
Ekip Touch can be configured with two different 3T modules:
Ekip Signalling 3T-1
and
Ekip Signalling 3T-2
.
NOTE: if different indications are not given, the information in the next chapter is
valid for both models; on the second module the inputs are called I51 (lopp 4-20mA),
I52, I53, I54 (PT1000)
The two modules can be installed at the same time on the same circuit-breaker so as to extend the
opportunities for measuring and monitoring the installation.
IMPORTANT: each circuit-breaker can only be fitted with one module per type.
Configuration with two modules of the same model is not allowed (example: two Ekip
Signalling 3T-1 modules)
Connections
For references about the connection and terminals, the circuit diagrams are
.
To connect the module to Ekip Touch, the kit sheet is
For PT1000 sensors, use insulated cables for resistance thermometers such as PENTRONIC TEC/SITW-24F
(Type TX) or similar. Maximum length 3 meters.
For the 4-20mA Current Loop sensor, use suitable cables up to 3 meters in length compatible with the
workplace in which the 4-20mA current sensor is used.
IMPORTANT:
the inputs are not insulated: regardless of plant voltage, the customer
must ensure there is insulation between each input and between the inputs and
power supply of the Ekip Supply module on the basis of the customer's own application
and network.
For applications in low voltage installations ABB suggests use of the dedicated
isolated external sensor PT1000, which can be ordered by code 1SDA085695R1,
is equippped with a nut and screw for use on busbars and is compatible with the
dielectric withstand and insulation levels established by standard IEC 60947-2 (Ui=
1000 V, Uimp= 12 kV).
Power supply
Ekip Signalling 3T
is supplied directly by the
Ekip Supply
module to which it is connected.
NOTE:
communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply
