Input The module enables the following quantities to be measured
Input Measurement Range Resolution Accuracy (1)
PT100/PT1000 Temperature -50 ÷ 250 °C (2) 0,01 °C ± 1 °C
4-20mA current loop DC current 0 ÷ 100 % (3) 0.1 % ± 0,5 % (4)

(1) accuracy values refer to 3T module without sensors. For complete accuracy, consider the characteristics of
the sensors and cabling used; accuracy increases by 0.5°C with the ABB sensor
(2) with ABB PT1000 sensor, the range is -25 ÷ 150°C
(3) the measurement is expressed as a percentage, where: 0% = 4 mA and 100% = 20 mA
(4) accuracy values refer to full scale: 0.5%= 0.1 mA

Interface Five signalling leds are available:

Figure 137
LEDs Description
Signals the on state and correct communication with the trip unit:
• off: module off
• on steady or flashing synchronized with the trip unit Power led: module on and
Power
communication with trip unit present
• flashing not synchronized with trip unit Power led (two fast flashes per second):
module on and communication with trip unit absent
Indicate the state of the input contacts:
• off: input disabled
I 41, I 42, I 43, I 44
• on steady: input enabled, sensor connected and measurement valid
• flashing: input enabled, sensor not connected and/or measurement not valid

Access from the display The following areas are activated on Ekip Touch if the Ekip Signalling 3T module is detected correctly:
• Measurements page, accessible from the Home page, containing the measurements of all the PT100/
PT1000 and 4-20mA Current Loop inputs of both modules 3T-1 and 3T-2
• information submenus in the About-Modules menu containing: serial number, module version and statuses
of sensors (Present/Alarm)
IMPORTANT:
• if one or more sensors are in the alarm status, the signal on the diagnosis bar will be:
Ekip Signalling 3T
• if a sensor is not enabled, the status indicated is: Present

Remote configurations The configuration of the module is available:
• via Ekip Connect, with communication accessories via service connector or with communication via
system bus
• via own communication system and Ekip Com modules installed on circuit-breaker, in the conditions
required by the trip unit (use System Interface for details)
All the measurements, states and alarms of the module are available in both conditions.

NOTE: parameters and measurements are distributed in Ekip Connect pages and communication
addresses sometimes nonsequential; references to the pages in Ekip Connect 3 are
given in the tables below
