MODES OF OPERATION
BE1-25/79TR Sync-Check Reclosing Relays have two primary modes of operation. They are the status
mode and settings mode. These modes are selected by momentarily pushing the front panel Settings Select
Up/Settings Select Down or the Reset switches.
Settings Mode
To program a setting or a parameter, select the settings mode by momentarily pushing the Settings Select
switches (either up or down). The front panel CE LED will flash to indicate the settings mode has been
entered. The CE LED continues to flash while in the settings mode. All reclose and voltage monitor
functions are disabled except for some of the active function LED's. The LED's (LL, LB, DL, and DB)
indicate existing voltage conditions.
To select a setting or parameter, momentarily push (either up or down) the front panel Settings Select
switches. Each time the switch is operated, another parameter is selected as the display scrolls through the
available settable parameters. These parameters are as follows.
