4 FDM - Frequency Deviation Monitoring
4.1.2 FDM Configuration
Automatic Monitoring of Powerline Frequency
It is possible to define an upper and lower limit for the powerline frequency and receive alarm messages (email,
syslog, SNMP traps) when a LANTIME device detects that the frequency measurement value is outside the
acceptable range.
With the FDM configuration menu the following parameters can be set:
Line Frequency:
configure frequency of the observed power line
Min Frequency:
an error occurs if the frequency reaches the min constraint
Max Frequency:
an error occurs if the frequency reaches the max constraint
Max Negative Time Deviation:
an error occurs if the frequency reaches the max negative constraint
Max Positive Time Deviation:
an error occurs if the frequency reaches the max positive constraint
Timezone:
used local timezone for reference time and powerline time
Activate Logging:
activate logging for FDM in XtraStats
Reset FDM
to restart the device
