CENTRON® Meter Technical Reference Guide 61
For meters with batteries, all logged events are retained through a power outage. For meters
without batteries, the Event Log is periodically written to non-volatile memory. Events that
occur just prior to a power outage may be lost depending on whether they were backed-up
or not.
The contents of the event log can be viewed using the meter programming software.
The following events may be configured for recording in the C12.19 C1SD/T/L register
Event Log:
 Billing Schedule Expired—billing schedule has expired and needs to be updated in
PC-PRO+ Advanced
 Clear Billing Data—billing data has been cleared upon initialization of the meter, or as
a secondary activity by authorized personnel
 Configuration Error—meter configuration was not successful
 Demand Reset—a demand reset occurred
 DST Time Change—DST adjustment forward or backward has occurred
 Event Log Cleared—Event Log was cleared by programming software
 Full Scale Overflow—Non-Fatal Error Codes for description
 Load Profile Error—Non-Fatal Error Codes for description
 Logon Successful—a user or option board logged on successfully to the meter
 Low Battery—Non-Fatal Error Codes for description
 Meter Reprogrammed—meter was initialized or reconfigured
 Power Outage—power was lost
 Power Restored—power was restored
 Rate Change—TOU rate change occurred
 Register Self Read—self read occurred
 Reverse Power Flow—Non-Fatal Error Codes for description
 Reverse Power Flow Restored—delivered power flow resumed after reverse flow
exceeded a configured threshold
 Season Change—TOU season change occurred
 Security Fail—logon with security code failed
 Security Pass—logon with security code succeeded
 Test Mode Entered—Test Mode or Alternate Test Mode was entered
 Test Mode Exited—Test Mode or Alternate Test Mode was exited
 Time Changed—a time adjustment forward or backward occurred
 TOU Schedule Error—Non-Fatal Error Codes for description
Security Codes
Register security can be provided with primary, secondary, and tertiary security codes that
prevent unauthorized communication with CENTRON products. A Primary security code
allows complete access to the meter. A Secondary security code allows full read access with
limited write access to perform an automatic demand reset and to access the Alternate and
Test modes. A tertiary security code allows read-only access. For more information about
security codes, refer to the PC-PRO+ documentation.
