FREQUENCY MENU
METERING PRODUCT USE (continued)
Display the required parameter for
modification.
Apply the same procedure as described
in Setup Menu for network voltage mo-
dification. Possible settings are described
in the previous table.
The frequency menu integrates 8 parameters described in the table hereunder.
The table explains parameters’ definition,
settings possibilities, and default values.
Over and Under frequency conditions are
verified on Mains and Generator side to
allow operation following operational flow
chart.
Over and under frequency detection levels
+ hysterisis are defined as percentage of
nominal frequency.
Hysteresis levels allow under and over
frequency conditions reset (frequency
needs to pass hysteresis level to reset).
