CHAPTER 17
Allure EC-Smart-Vue Communicating
Sensor Troubleshooting
Symptom Status Description
When the Allure EC-
Smart-Vue sensor is
connected to a
Controller, the LCD
display on the sensor is
blank with the backlight
ON for about 30 to 45
seconds
Firmware upgrade in
progress
Wait for the upgrade to complete. Do not disconnect the Allure EC-Smart-
Vue sensor from the controller as the upgrade will only restart once it is
reconnected.
Table 35: Allure EC-Smart-Vue Sensor Normal Operation
Symptom Possible Cause Solution
Allure EC-Smart-Vue
sensor 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 controller
and that the patch cables are plugged-in to the connectors. See
Cat 5e Cable
Subnetwork Data Bus 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 correctly.
See
Cat 5e Cable Subnetwork Data Bus for more information.
Device is not
communicating with
controller
Is the address
correctly set to a
unique address? Each Allure EC-Smart-Vue sensor must be set to a unique address for each
controller. See
Commissioning a Connected VAV Controller with an Allure EC-
Smart-Vue Sensor .
Is the device too far
from controller? Verify the distance between the device and the controller. See Subnetwork
Data Bus Length .
Is there a configuration
problem? With EC- gfx Program, check the configuration of the sensor, for example, is it
enabled? Refer to the EC-
gfx
Program 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 the figures in section
EOL Terminations .
Allure EC-Smart-Vue
sensor motion detector
window indicator is
always ON
Does the connected
controller have Allure
EC-Smart-Vue sensor
firmware that supports
the motion and CO
2
sensor?
When the Allure EC-Smart-Vue sensor is connected to a controller, its
firmware is loaded from the controller. In this case, the controller has an
earlier version of Allure EC-Smart-Vue sensor firmware that does not
support the motion or CO
2
sensor. To upgrade to the latest Allure EC-Smart-
Vue sensor firmware, download the firmware from the Software Center and
refer to the firmware upgrade procedure in the EC-
gfx Program User Guide.
The Motion or CO
2
output of the
associated ComSensor
block always reads
NULL in EC-
gfx Program
The CO2 sensor
readings are too high,
too low, or inconsistent
between sensors
Immediately after
installing the Allure
EC-Smart-Vue sensor
with CO
2
sensors, are
the CO
2
sensor
readings incoherent?
If the CO
2
sensor readings seem unusual or show inconsistencies between
sensors in the same building right after installation, the following reasons
should be taken into consideration:
-Concentration levels in each space may be different
-The installer may have unintentionally blown into the sensor while installing
it.
