Fault Code Latch Description Action
drift.
F111/F211 Cal Line
Shortage Fault
Non-Latch This fault occurs when the
IR400/IR700 sensor Cal Line
(brown wire) is shorted to
ground.
Check the wiring and sensor
connection.
F112/F212 Zero
Calibration Failed Fault
Latch This fault occurs when last
zero calibration has failed.
Use the “Reset Sensor” entry in main
menu to reset the fault. Re-calibrating
the sensor will also clear the fault.
Replace the sensor if this fault
persists.
113/F213 Full Span
Calibration Failed Fault
Latch This fault occurs when last full
span calibration has failed
Use the "Reset" entry in UI menu to
reset the fault. Re-calibrate the sensor
will also clear the fault. Replace the
sensor if this fault persists.
F114/214 Cal Check
Timeout Fault
Non-Latch This fault occurs when the
last Cal Check has failed due
to timeout.
Check whether test gas is left on for
Calibration Check mode. Remove the
test gas if it is left on. Once it is
cleared, the unit will return to normal
operation.
F115/F215 Sensor
Configuration Reset
Fault
Latch This fault occurs when the
configuration parameters for
sensor have been reset.
Check the sensor parameters,
including calibration level, range,
warning and alarm set points. Verify
all these parameters are configured as
intended. Recalibrate the sensor to
clear the fault if needed. Running
through the calibration check is
recommended.
F116/F216 Calibration
Required Fault
Latch This fault occurs when the
sensor is in need of
calibration.
Recalibrate the sensor.
F117/F217 Bead Off
Fault
Latch Indicates that the combustible
sensors beads are OFF.
Make sure the environment is free of
dangerous combustible gas and then
use the “Reset” entry in UI menu to
acknowledge the fault or cycle power
to the sensor. Let the sensor warmup,
then recalibrate the sensor. If this
does not resolve the issue, replace the
sensor.
F118/F218 Analog
Output Mismatch Fault
Non-Latch This fault occurs when the 4-
20mA analog output loop is
malfunctioning.
Check the 4-20mA analog output loop
is closed properly with nominal
250ohm load resistor installed. The
fault will be cleared automatically
once the loop is closed and wires are
properly connected.
