Symptom Possible Cause Solution
Allure EC-Smart-Vue sen-
sor screen is blank & back
light is off
Is the Allure EC-Smart-Vue
sensor connected to the
controller?
Verify that the Allure EC-Smart-Vue sensor is connected to the control-
ler and that the patch cables are plugged-in to the connectors. See Cat
5e Cable Subnetwork Data Bus on page 79 for more information.
Is power being supplied to
the controller?
There may be no power being supplied from the controller. Check if the
controller has power or if the controller's internal fuses have blown or
tripped.
Is the cable connected to
the controller and Allure
EC-Smart-Vue sensor?
Verify wiring.
Was the patch cable made
onsite?
Verify that the RJ-45 crimp connectors were installed on the cable cor-
rectly. See Cat 5e Cable Subnetwork Data Bus Cable Requirements
on page 79.
Expansion module is not
communicating with control-
ler
Is the address correctly set
to a unique address?
Each expansion module must be set to a unique address for each con-
troller. See Commissioning a Controller with an Allure EC-Smart-Vue
Sensor on page 98.
Is the device too far from
controller?
Verify the distance between the device and the controller. See Subnet-
work Data Bus Length on 75.
Is there a configuration
problem?
With EC-gfxProgram, check the configuration of the sensor, for exam-
ple, is it enabled? Refer to the EC-
gfxProgram User Guide for more
information.
Have the subnetwork EOL
settings been correctly set?
Only the last module on the subnetwork data bus must have its EOL
termination set to ON. See Figure 51, Figure 53, and Figure 54. When
one or more ECx-400 Series IO Extension modules are connected to
the controller, only the last ECx-400 must have its EOL termination set
to ON. See Figure 61.
