BATTERY BACKUP (BBU) DIAGNOSTICS
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.
