Input The module enables the following quantities to be measured
Input Measurement
PT100/PT1000 Temperature
Current loop
DC current
4-20 mA
accuracy values refer to 3T module without sensors. For complete accuracy, consider the
(1)
characteristics of the sensors and cabling used; accuracy increases by 0.5 °C with the ABB sensor
with ABB PT1000 sensor, the range is -25 ÷ 150 °C
(2)
(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
Accuracy valid within the 0 to 130 °C range with module at 25 °C ambient temperature. The
(5)
accuracy value is ± 2 °C over the whole range, with module at 25 °C ambient temperature

• Measurements page, accessible from the Home page, containing the measurements of all the
PT100/PT1000 and 4-20 mA 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
• 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

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 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
• on steady: input enabled, sensor connected and measurement valid
• flashing: input enabled, sensor not connected and/or measurement not valid
