Battery Backup Unit (BBU) Diagnostics
GREEN LED:
All systems are normal.
• A solid LED light indicates the batteries are fully charged.
• A flashing LED indicates the batteries are being charged.
NOTE: Batteries do not have to be fully charged to operate the
motor unit.
YELLOW LED:
The motor unit has lost power and is operating off of
the BBU.
• A solid LED with beep, sounding approximately every 2
seconds, indicates the motor unit is activating the door and is
operating off of the BBU.
• A flashing LED with beep, sounding every 30 seconds,
indicates batteries are low.
• Once the power is restored the BBU will recharge. This is
indicated by a flashing green LED.
RED LED:
An error has been detected and the BBU will automatically shut
off. The BBU will attempt to restart by reconnecting to the
batteries. If the error is still present it will shut itself off again.
This process will repeat every 5 minutes or until the error has
been resolved. This is used to prevent further draining of the
batteries.
• If a red LED remains on when the power is restored, and is
accompanied by a beep sounding every 30 seconds, please
call for service.
