MESSAGE PAGE
When there is a message for the operator to review a flashing M will
be displayed on the display and the Remote Lamp discrete will be
set. When the MSG key is pressed the flashing M is removed, the
Remote Lamp discrete is reset and the message page is displayed.
System, and ALE AMD messages can be reviewed on this page.
The Operation / Mode field is cursorable on this page to allow exiting
of this page. Pressing the CLR or MSG key also exits this page and
returns to the last page displayed.
The arrow on line two indicates that there are more messages to
review. Once the message is reviewed the message flag on the idle
pages is removed. System messages are cleared once they are
read. The order in which the message types are displayed is
System, ALE_RX , SoundFrom. If there are no new messages then
the received ALE messages are displayed to allow past messages to
be reviewed.
System messages are mainly faults; for example Figure 3-58 shows
an over temperature fault.
