Install the BTS on the side of the battery below the
electrolyte level. It is best to place the
sensor between batteries and place the batteries in an
insulated box to reduce the influence of the ambient
temperature outside the battery enclosure. Ventilate the
battery box at the highest point to prevent hydrogen
accumulation.
A multi-color LED indicator is provided to indicate the
operating status of the C40. A color-coded label is included
on the cover of the C40 to explain the status LED’s
operation. When the C40 is in Charge Control or Load
Diversion mode, the LED will be green. When in Load
Control mode, the LED will be red. An orange LED indicates an error condition. When
battery equalization is in process, the LED will alternate between red and green.
- The battery has entered the FLOAT stage of the charging process. The
status LED will remain solid unless the batteries drop below the Float voltage setting for an
accumulative period of one hour. This allows the user to confirm that the system reached
FLOAT during the charging process when checked at the end of the day. Reaching the
FLOAT stage frequently is a good indication of proper system operation and will maximize
battery life and performance.
- indicates that the controller is in the Charge Control or Diversion Control
mode and the battery is not fully charged. As the battery voltage approaches the Bulk
setting, the status LED will blink green several times (up to 5) and then pause. This
indicates that the battery voltage is approaching the Bulk setting and provides an indication
of the battery condition.
