5.1 Alarms
The MX-2100 generates two types of alarms, designated as state and event.
•
A message indicating a
state
alarm is displayed only when the alarm condition
is present, and is automatically removed when the condition is cleared (if the
alarm is being displayed, it will disappear only when the display is refreshed by
scrolling).
•
A message indicating an
event
alarm persists even after the event that caused
the alarm condition is cleared.
The alarm messages can be displayed on the front-panel LCD, and are also sent to
the supervision terminal or management station.
Alarms intended for display on the LCD are stored in the alarm buffer for the LCD
display, which can store one alarm event of each type. The MX-2100 operator can
view the contents of the alarm buffer, and can clear event alarms. This procedure
is explained in the
Front Panel Controls and Indicators
section of the
Operation
chapter. Using the
DEF ALM DEBOUNCE
command, the MX-2100 operator can
define the debounce time (in seconds) for each alarm code or mask the alarm.
Refer to the
Alarms
appendix for more information, and for a list of the alarm
messages displayed by the MX-2100.
If the problem cannot be corrected by carrying out the listed actions, have the
MX-2100 checked by the technical support personnel.
