#D040II0I 760 Series Battery Backup System (BBUS) Issued 02/04/2009 #D040II0I 760 Series Battery Backup System (BBUS) Issued 02/04/2009 General Unit Behaviour The BBUS has two main mo des of operation. 1. Energised (Vehicle Supply Present) • Electrical power is drawn from the vehicle supply. • Power for rhe load is derived from the same vehicle supply and automatically routee to the Output, via an internal power relay. • If required charging of the internal batteries will commence. • The BBUS continually monitors the incoming vehicle supply. If the voltage falls to less than the minimum operating...

760 Series Battery Backup System (BBUS) Battery Management and Protection Features As soon as the battery is fully charged, the zero-voltage slope that occcrs at the battery terminals is detectee. Boost charging halts and the unit enters top-up charge mode. During discharge the battery terminal voltage is monitored. When this voltage drops below a critical value d i scharging is hatted . Charging only occurs when the battery pack is within the correct temperature range. The battery will only be charged when the terminal voltage lies within a valid specified range. If this condition is not satisfied...
