Alarms with an asterisk (
W
) are non-latching. A non-latching alarm clears itself automatically when the alarm
condition goes away. All other alarms are latching and must be manually reset by using the HMI Reset
button or the RA=0 command.
Any programmable alarm can also be used in programmable logic expressions without being programmed
to be reported by the programmable alarm reporting function. The ALMLGC variable is provided for this
purpose. Programmable alarm variables can be masked to drive BESTlogic variable ALMLGC by using the
SA-LGC command.
Programming Alarm Priorities
Alarm settings include Major, Minor, and Logic alarm priorities, Demand alarm points, and the Breaker alarm
points. Programming details for Demand alarm points is available in the Demand Functions subsection.
Refer to the Breaker Monitoring subsection for details about programming Breaker alarm points. Major,
Minor, and Logic programmable alarm settings are summarized in Table 6-18.

SA-MAJ/MIN/LGC Command
Purpose:
Read or set major/minor/logic alarm setting mask.
Syntax:
SA-<type>[=<alarm num 1>/<alarm num 2>.../<alarm num n>]
Comments: type = MAJ (Major), MIN (Minor), or LGC (Logic)
alarm num = alarm identifier
Privilege G or S password access is required to change settings. See Table 6-17 for
SA_MAJ/MIN/LGC settings information.
SA-MAJ/MIN/LGC Command Example
1.
Set the Major Alarm to trigger when the trip circuit voltage and continuity monitor asserts, when breaker
failure occurs, or when virtual output 15 is TRUE.
