Note 2� Optima or
Excel: Sensor fault or
warning code (Note 4)
If repeated, check supply voltage, check cable loop impedance, check
terminal connections
F103

XNX temperature
(Celsius)
Check location for heat sources� Fit with sunshade or other protec-
tion� Change the transmitter’s location� Check temperature in Info-
>Transmitter Status to ensure temperature is being measured properly�
F104
XNX 24 VDC Sup-
ply Bad
All
Non-latching
2 seconds
XNX supply voltage

Check the wire of the 24V power supply to the transmitter and the power
supply operation�

F108
XNX mA Output
Loop Failure
All
Latching
2 seconds
mA output error (mea-
sured mA - set mA)
Check wiring of mA output from XNX� Check that switches S1 and S2 are
set correctly� Note that if F108 is not resolved quickly, an F149 (Internal
Communication Failure - mA) will also be generated� When the cause of
F108 is resolved, both the F108 and F149 will be cleared�
