Possible remedy
C100 hex will be added to the FALS number (001 to 1FF hex)
and the result will be stored in A400 as the error code (C100 to
C2FF hex).
Check the conditions for executing FALS instructions and
remove any causes for the user-defined error.
Possible remedy
Cycle the power supply. The Unit may be faulty. Consult your
OMRON representative.
