OPTIONAL BATTERY BACKUP TECHNICAL INFORMATION
The Battery Backup System comes as a factory installed or field installed option. This will provides
approximately 8 hours of auxiliary power automatically to the roller apparatus should a primary
mains power failure occur. This integrated system consists of two sealed lead acid batteries and an
automatic charging system.
Operation with Battery Backup
The battery backup system utilizes two sealed lead acid batteries which must be maintained in a
fully
charged state to insure proper auxiliary operation. The charging circuitry charges the batteries
whenever the roller apparatus is plugged in and operating.
If primary mains power is lost while a roller apparatus is in normal operation, the battery back-up
system will automatically and seamlessly switch the roller apparatus to operate and function
normally on its internal batteries. Once primary power is restored, the charger will automatically
switch the apparatus back to normal operation.
