Section 9 Read and change settingsAbout this chapterThis chapter describes how to find and change settings and parameters. The chapteris divided into two sections which match the way the two categories of settings aredivided up in the HMI. The General settings group consists of those parametersthat cause an automatic restart of the IED. The Setting group N consists of sixgroups of settings with default values for all parameters. These do not require orcause a restart once they have been changed. Time, synchronization and theactivation of setting groups are also dealt with here.It takes a minimum of three minutes for the IED to save the newsettings, during this time the DC supply must not be turned off.Do not perform a setting change at the same time as a hardwarereconfiguration. Doing so might cause the IED to malfunction.9.1 System time and synchronization9.1.1 System timeMain menu/Settings/Time/System timeUnder System time, the system clock date and time are set. If there is a need tochange the time settings in the LHMI the changes will take effect immediately. Toconfirm the new settings, press E. To remove the changes, press C.9.1.2 Time synchronization9.1.2.1 OverviewThe synchronization settings are divided into categories Time synch, Time synchBIN, Time synch SNTP, Time synch DST Begin, Time synch DST End, Timesynch time zone and Time synch IRIG-B. The settable parameters are found undereach category.9.1.2.2 TimeSynchMain menu/Settings/Time/Synchronization/TIMESYNCHGEN:x/General1MRK505209-UEN E Section 9Read and change settings41Operator's manual
