Setting Groups

Four setting groups allow adaptive relaying to be implemented to optimize

BE1-11d settings for various operating conditions. Automatic and external

logic can be employed to select the active setting group.

Clock

The clock is used by the logging functions to timestamp events. BE1-11d

timekeeping can be self managed by the internal clock or coordinated with

an external source through a network or IRIG device.

A backup capacitor and additional battery backup are provided for the clock.

During a loss of operating power, the backup capacitor maintains timekeeping

for up to 24 hours depending on conditions. As the capacitor nears depletion,

the backup battery takes over and maintains timekeeping. The backup battery

has a life expectancy of greater than five years depending on conditions.

IRIG

A standard unmodulated IRIG-B input receives time synchronization signals

from a master clock. Automatic daylight saving time compensation can be

enabled and set for floating or fixed dates.
