Yes. The larger the battery the more times the gate can be operated when a power failure occurs. For high volume applications it may be necessary to change the battery charger to ensure that the total energy into the battery exceeds the total energy drawn out of the battery over a long period of time.

Check that the green IRB LED is on. If not, find out why

The problem may be caused by a loose connection in the controller 12V DC power supply circuit. What happens is that the controller momentarily loses its 12V DC supply (it is often a drop in voltage that occurs so quickly that it is not possible to measure it with a standard volt meter) and the P/C microprocessor on the controller resets. It is very easy to see if this is the problem because the STATUS LED flashes 5 times as the motor stops, and all the monitoring LED’s (STATUS, L1 AND L2) will be switched off.
