1. RMBC64 24D DC HAWK 3 STAGE DC BATTERY CHARGER OPERATORSMANUAL 2009 RMBC64 24D DC ELECTRONIC BATTERY CHARGER Overview The RM BC64 24D DC has been designed for charging two HAWK batteries Designed to provide all the intelligence to safely consistently and efficiently fast charge the HAWK battery Functional Description At switch on from the mains the two top row banks of green LEDs will give two flashes to confirm that the charging circuits are operating correctly and that there is no malfunction with the charger The unit is fitted with a selectable buzzer and a flashing green LED per channel to inform the operator when the battery or batteries are fully charged and has reverted to trickle charge Two seconds after the flashes have finished the charger is ready for use Once either of the red start buttons have been pressed the charging process for that bank begins Both the second third fourth and fifth row of red LEDs will be on with the top row of green LEDs flashing This indicates that all the charging circuits are operating correctly within the bank W hen the charge cycle is complete the red LEDs within that bank will be off and the top row of green LEDs will all be constant together with the red trickle charge LED flashing and if the audio alert is switched on the buzzer will be sounding If the buzzer is switched in it will sound when the last flashing green LED is constant informing the operator that t
