Reporting and Alarm Functions

the HMI Reset key while viewing screen 1.3 or using the RA=0 or RA-REL=0 commands, then the relay will
attempt to return back online by issuing a software reset. The relay resets by going through a full startup and
initialization cycle. If no problems are detected, the relay returns online and enables protection.
Major, Minor, and Logic Programmable Alarms
The programmable alarms function covers all circuits monitored by the continuous self-test diagnostics
function that do not affect the relay core functions. Alarm functions used to monitor the power system and
equipment are also part of the programmable alarms. Table 6-17 provides a detailed list of all programmable
alarms. The programmable alarm points can be prioritized into Major and Minor alarms using the SA-MAJ
(setting alarms, major) and SA-MIN (setting alarms, minor) commands. Major alarm points, when triggered,
cause the HMI Major Alarm LED to light and the BESTlogic variable ALMMAJ to assert. Minor alarm points,
when triggered, cause the HMI Minor Alarm LED to light and the BESTlogic variable ALMMIN to assert.
