Input
The module enables the following parameters to be measured
Input
Measurement
Range
Resolution
Accuracy
(1)
PT1000
Temperature
-50 .. 250 °C
0.01 °C
± 0.25 °C
(2)
4-20mA current loop
DC current
0 .. 100 %
(3)
0.1 %

(4)
NOTES:
(1) accuracy refers to the 3T module without sensors; for complete accuracy, consider the
characteristics of the sensors and cabling used
(2) accurate within the range -25 .. 250 °C; in the complete range it is: ± 0.5°C
(3) the measurement is expressed as a percentage, in which: 0 % = 4 mA and 100 % = 20 mA
(4) accuracy refers to the full scale: 0.5 %= 0.1 mA
Interface
Five signalling LEDs are available:

Description
Power
Reports ON status and correct communication with trip unit:
 off: module off
 fixed or flashing light synchronized with power LED of Ekip Touch: module ON and
communication with Trip unit present
 flashing not synchronized with power LED of Ekip Touch (two rapid flashes per
second): module ON and communication with Trip unit absent
I 41, I 42,
I 43, I 44
Indicate status of the input contacts:
 off: input disabled
 fixed on: input enabled, sensor connected and measurement valid
 flashing: input enabled, sensor not connected and/or measurement not valid
Access from
display
If the Ekip Signalling 3T module is detected correctly, the following areas became available on
the trip unit:
 Measurements page, accessible from Home (see page xx), containing the
measurements of all the PT1000 inputs and 4-20mA current loops of both 3T-1 and 3T-
2 modules
 information submenu in the Modules-Information menu containing: serial number,
module version and sensors status (Present/Alarm)
IMPORTANT:
 if one or more sensors are in alarm status, this signal is activated on
the diagnosis bar: Ekip Signalling 3T
 if a sensor is not enables, the reported state is: Present
Remote
configurations
The module configuration is available:
 via Ekip Connect, with communication accessories from service connector or with
communication from system bus
 with its own communication system and Ekip Com modules fitted to the circuit-breaker
in the conditions prescribed for the trip unit (use the System Interface for the details)
In both the conditions, also all the measurements, statuses and alarms of the module are
available.
NOTE: parameters and measurements are distributed on Ekip Connect pages and
communication addresses that are sometimes not consequential; the following tables
show the page references to Ekip Connect 2
