BE1-25/79TR Functional Description

3-8

Live Line (LL)

Condition adjustable from 10 to 135 Vac.

Enabled when line voltage is greater than setting.

Indicated by front panel LED when LED is ON.

Dead Line (DL)

Condition adjustable from 10 to 135 Vac.

Enabled when line voltage is less than setting.

Indicated by front panel LED when LED is ON.

Live Bus (LB)

Condition adjustable from 10 to 135 Vac.

Enabled when bus voltage is greater than setting.

Indicated by front panel LED when LED is ON.

Dead Bus (DB)

Condition adjustable from 10 to 135 Vac.

Enabled when bus voltage is less than setting.

Indicated by front panel LED when LED is ON.

NOTE: For 3 phase line and 3 phase bus type relays, all three phase A, B & C must be in the same band

for a live or dead condition to exist.
