Diagnostic display analysis example

A diagnostic code of AL09 is analyzed as follows:
First character = A = The HPMM is in the Alive state.
Second character = L = The card file is a left 7-Slot file.
Third and Fourth characters = 09 = The pinned UCN node number
Refer to subsection "Redundant Analog Output IOP Failure Diagnosis" in "Fault Isolation" for additional
Diagnostic display codes and more detailed information.

Detailed Diagnostic display switch

A pushbutton switch (Display) under the front cover of the High-Performance Comm/Control card
controls additional detailed diagnostic information displays. The additional diagnostic codes are
presented in a fixed sequence.
This detailed diagnostic information becomes extremely useful when troubleshooting.
The switch effects only the behavior of the display and will not effect the operational capability of the
High-Performance Comm/Control card.
Refer to the "Fault Isolation" section for troubleshooting information, failure code charts including
suggested corrective actions, and additional information on detailed diagnostic displays and the
sequences of presentation.

Debug connector

The High-Performance Comm/Control card has a debug connector (Debug) under the front cover. The
connector is used by Honeywell engineering with specialized equipment and design level knowledge.
The factory also uses the connector.
