What is alarm 47 on the Series 2000 Circuit Monitor (CM2000)?

Issue
A CM2000 series circuit monitor is displaying alarm code 47 on the front display.

Product Line
CM2000 Series Circuit Monitor

Environment
Onboard Alarms

Cause
Alarm code 47 is defined as "Suspended Sag/Swell". The alarm is to identify an excessive number of Sag/Swell events being generated on the meter.

An "excessive number" of Sag/Swell events is defined as:
More than 48 events total from all Sag/Swell Alarms in any 500ms period, or more than 6 events from any single Sag/Swell Alarm in any 500ms period.

Alarm code 47 is active when event 47 is true which occurs when register 2038 on the meter is not equal to zero.  If the user deactivates alarm 47 without clearing Register 2038, the alarm will immediately be reactivated and asserted as true.

Resolution
To clear alarm 47, write a 0 to register 2038.
