Alarm Menus Description
Press the "ALARM" key under the 'Category Group' and menu 27
(Alarms)
will be displayed. Menus
27-35 are the alarm menus.
Menu 27 has four screens. This menu is a display and does not require a password. The values
displayed indicate the current alarm and the conditions at the time the alarm reported. When another
alarm reports the values in this menu will be shifted to menu 28
(Alarm Buffer #1)
. Each time another
alarm reports the alarms are shifted and the alarm buffers #1-#8
(Menu 28-35)
are filled. The oldest
alarm will be removed from memory. This allows for the current alarm and eight
(8)
previous alarms to
be recorded for troubleshooting purposes.
