THE ALARMS FAST-ACCESS KEY 

 

Fig. 61. The ALARMS fast-access key 

 
Pressing the ALARMS fast-access key displays the main alarm menu screen to 
enable selection of the following: 
 

 alarm buffer 

  points in alarm 

 critical alarms 

 non-critical alarms. 

 

Alarm Buffer 

The last 99 alarms are stored in the alarm buffer. Typical alarm information 
includes: 

  Date and time the alarm occurred 

  Name of the data-point in alarm 

  Value/state of the data-point in alarm 

  Alarm text, e.g. MIN1 alarm. 

 
When the alarm memory capacity is exceeded, the first alarm is overwritten. 
Alarms are organized on a first in, first out basis. The contents of the alarm buffer 
can be displayed on the Excel 50 MMI.
