F6
Try to
Calibrate
Again
The unit did not calibrate correctly, due
to:
• the absence of gas,
• no radio connection to controller,
• a sensor error, or
• an analog sensor board error.
1. Recalibrate the sensor element and
verify that gas is present during
calibration.
2. Ensure the AirLink 6940XP has a
radio connection to a controller.
3. Replace the sensor element.
4. Replace the sensor housing.

Check
Radio
The AirLink 6940XP has lost communi
-
cation with the Primary Monitor due to:
• Incorrectly configured Network ID.
• AirLink 6940XP is obstructed/too far
from the Primary Monitor.
• Radio module is not working in the
sensor assembly
1. Check that the Network ID on the
AirLink 6940XP matches the Primary
Monitor Network ID
2. Move the AirLink 6940XP away

AirLink 6940XP Warning Symbols (for LEL Type Only)
Problem
Cause(s)
Solution(s)
The sensor is undergoing a rapid
temperature change, resulting in the
potential loss of accuracy.
1. Once the sensor element temperature
has stabilized, the warning will clear.
The sensor element is in the warm
up period.
1. The gas level reading will gain
accuracy and the warning will clear
upon completion of the warm up
period. Calibrate the sensor element
when the warm up period is complete.
The sensor element is experiencing
high electromagnetic interference
(EMI).
1. Remove any source of
electromagnetic interference (EMI).
2. Reposition or relocate the AirLink
6940XP.
