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