3.4 Troubleshooting
Errors are annunciated by:
•
The module’s status LEDs (see Table 3-1)
•
The 4-mation configuration software - Error codes and messages; refer to Diagnostic Error Codes
and Software Messages (document number CG39-19) or 4-mation ’s help file.
The 4-mation configuration software runs on an IBM-compatible PC or the APACS+ Rack-mounted
Industrial Server (RIS).
Module status LEDs are located on the EAM’s bezel. Note LED indications, then refer to Table 3-1 for
EAM status and
4-mation to determine the course of action.
Interconnect I/O Cable pin assignments are listed in Table 2-3. These are provided for troubleshooting a
suspect cable.
As necessary, check field wiring and field-located devices.
The EAM, Termination Strip, and Marshalled Termination Assembly are not field serviceable, except for
the EAM power fuse replacement. A failed assembly should be returned to the factory for repair.
