Front Panel User Interface Description
The front panel User Interface provides visual indication of DC output voltage and current, as well as the
charging mode (FLOAT or EQUALIZE), equalize time elapsed, and status of all alarms. The front panel
User Interface is shown below in
FIG 4
.
NOTE:
With no AC mains supply present and with a battery connected to the output of the charger, and with the
DC output breaker closed, the display will operate. Battery voltage and alarm status will be displayed.
With the system in this condition, the charger draws between 200 and 240mA from the battery.
