LCD Screen Is Not Working on Battery Backup

The LCD screen of your PULSE 500 Series door operator doesn't work on battery backup because the battery backup system only powers the encoder to remember the door position. It does not supply power to the screen in the PULSE 500 Series.

Battery backup will only power the motor directly when OPEN/CLOSE is pressed via the Drive +/- connections on the control board.
