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
Description
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
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

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

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)
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
