20 “Span Calibration
Fault”
ON/ON/OFF Indicates the sensor
did not pass the Span
calibration operation.
Acknowledge the fault
by pressing and
holding both EZ touch
buttons at the same
time for up to 5
seconds. The unit will
revert to the previous
calibration so that the
unit can continue to
detect gas while
troubleshooting fault.
Causes for this fault
include:
(1) Span gas is not
applied within the
calibration time-out
period.
(2) The incorrect span
gas is applied or
the span value is
not set correctly in
the Sensor
Settings.
(3) The sensor is at its
end of life.
Check the span gas
concentration and the
sensor span value
setting to ensure that
the correct span gas is
being used. Go
through the calibration
process again after
verifying. If fault
persists, replace the
sensor.
14 “TEDS CRC-16 Error” ON/ON/OFF Indicates the sensors
datasheet is invalid.
Reset the sensor.
Verify the sensor
settings (if different
from default), then
recalibrate the sensor.
40 “Unknown Error” ON/ON/OFF Indicates that a sensor
is returning an
unknown error
condition.
Replace the sensor or
update the main PCBA
software.
