Fault Code Bit Pattern Table
This is an 8-bit pattern indicating the current error num-
ber in the system. The bit pattern is accompanied by the
Error Present bit.
If the PLC displays error messages, the PLC program-
mer should translate the bit pattern to the corresponding
descriptive string. See the following table to translate the
fault code bit pattern to a descriptive string. The Error
Number column is used for reference to aid the PLC
programmer in translating from fault code bit pattern to
error string. When error number 255 with bit pattern
“11111111” occurs the user should check the ADM for
error details.
NOTE: This manual is available at Graco.com. To pre-
vent having to manually re-type these error codes and
strings into your PLC program, go to Graco.com and
retrieve the electronic version of this manual then copy
the following table from the PDF.
