Door Not Working on Battery Backup Power

For drained or dead batteries:

• Check the batteries' voltage first. If it's low (less than 10V DC per battery), allow them to charge for 24 hours with AC power ON.
• If the batteries do not charge after this period, they should be replaced.

For door balance issues:

• A door not functioning on battery power may result from the door being improperly balanced. Select 'BALANCE CHECK-UP' from the STARTUP MENU and adjust the door's balance as required.

For main power interference:

• The door might not operate on battery power because the main power is still active. Disconnect the unit from the main power supply by unplugging/disconnecting it. This ensures the system attempts to switch to its built-in battery backup power.

To verify battery backup functionality:

• Check the screen with a flashlight. If text is visible despite the screen being dim, then the operator is in battery backup mode.
• On the PULSE 300, battery backup mode will keep all peripherals powered and will automatically open/close via a momentary press of OPEN/CLOSE while the batteries are still sufficiently charged.
• Once the batteries get too low, to conserve power, the unit will turn off most devices and require constant pressure of OPEN/CLOSE to operate the door.
