General Drive Errors

These errors usually result from a miscommunication between the drive
processors or involve a mechanical malfunction. In most cases, these types of
errors report an error message and an FSC to the control panel. The only
exceptions are power supply problems and display malfunctions. The FSC can
be used to determine a recovery procedure.

Some error messages can be cleared by pressing the Enter button on the
control panel, others by cycling the power to the library. Often the module will
resume normal operation. Other errors are repeated when the operation is
attempted again. Such recurrent errors may require more extensive recovery
procedures, such as replacement of a part.

To aid you in localizing persistent errors, there are Customer Engineer
diagnostics available in the Maintenance Submenu and a user diagnostic
available on the Demo Submenu. The diagnostics are described at the end of
this chapter.
