Tamper, Event, and Alarms Indicator Behavior: Two bits are used to log the above
alarm, event, and tamper occurrence Groups.
All Indicators are "Non-Latching", meaning the R300 board continues to increment for
each and every alarm, event, or tamper occurrence each time they happen.
Event, Alarm, and Tamper Assignments for the CENTRON R300CD/CD3 and CENTRON
Polyphase R300CD/CD3 Meters:
For all Fatal Errors, the R300 stops transmitting.
For the Diagnostic Checks and Non-Fatal Errors, transmission can be controlled via
PC-PRO+ Advanced software.
