Battery Backup; Error Codes - LiftMaster myQ SL400EVK Manuel D'installation

8. BATTERY BACKUP

Battery Back-Up Mode (BBU)
Optional 12V, 2.2Ah lead batteries SKU 490EV (optional, not included) can be mounted inside operator housing.
Follow the manual of SKU Nr 490EV for exact installation procedure.
A Flashing lamp (if mounted) will flash 2 seconds every 10 minutes indicating BBU mode and power loss.Control board will switch into stand-by mode with active radio
receiver accepting radio control device commands only. All other accessories and peripheral devices will not be functioning. When in Battery Back-up mode, myQ Smart-
phone Control and wireless myQ devices will be disabled. Full charged battery capacity shall support up to ~20 cycles at a rate of 2 per hour. After 24 hours of BBU mode
the battery shall provide power for 1 complete opening and closing cycle.
Please note that only the specified battery can be use. Use of any other battery leads to loss of warranty and loss of liability of LiftMaster for any related damages resul-
ting from use of unspecified batteries.

Solution
Check if AP is set to 00. If yes, change to correct application setting.
1) Check if IR1 is not connected, or wire is cut.
2) Check IR1 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing hanging on gate that
may cause IR blocking.
1) Check if IR2 is not connected, or wire is cut.
2) Check IR2 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing blocking the IR.
1) Check if IR3 is not connected, or wire is cut.
2) Check IR3 connection, change wires if needed.
3) Align IR transmitter and receiver to make sure both LED is on,
instead of blinking. Make sure there is nothing hanging on gate that
may cause IR blocking in short time.
1) Check if the 8.2 kOhm safety edge is properly connected or if the
8.2 kOhm resistor is installed.
2) Check safety edge wires and replace wire if needed.
3) Check if safety edge is pressed.
1) Check if STOP switch is open or damaged.
2) Check if STOP switch is disconnected. If yes, then reconnect
STOP switch or change the respective Input setting to other value.
1) Check if mag switch is connected correctly. If not, fix the connec-
tion.
2) Check if Mag block drops from switch or fuse is broken.
Switch off power for 20 seconds and reset to check if control board
recovers. If not, change control board.
