BGUS-D • SG-D

CHARGER BOARD SLEEP MODE

When primary AC power is not available, the operator will continue to

operate in battery only mode if the charger board is set in its RUN mode

(see Battery Backup Charger Conﬁ guration). Accessories wired into

the operator will continue to draw power, even when the operator is not

opening or closing the gate. This can dramatically reduce the amount

of standby time available from the batteries.

To extend the available standby time, the charger board has a “sleep”

mode feature which will turn off power to all controls except for any that

are wired according to the schematics below. By removing the black

jumper cap JP1 located in the upper right hand corner of the charger

board this feature can be enabled. After ﬁ fteen minutes of inactivity, all

controls except those wired as shown below will turn off. Those wired as

shown will continue to have power at all times and will upon activation

generate ﬁ rst a “wake” signal that will power all controls back up, and

then create either an open signal or single button signal, depending on

how the wire jumper shown below is connected.
