2.3.9. Using the front panel security feature
The AT30 charger is shipped with all the front instrument panel keys
enabled. You can disable the following front panel functions:
•
Selecting Equalize method
•
Changing settings using the EDIT/ENTER key
•
Toggling the high dc voltage shutdown feature
To disable the front instrument panel keys, open the AT30 door and locate
the small plastic jumper
J9 on the right side of the main control board.
See the figure below.
Move the jumper up to the
DISABLE position (pins 2 and 3). With this
setting, only the front panel METER MODE and CHRG MODE keys will
function. All indicators will still work normally. Return the jumper down
to the
ENABLE position (pins 1 and 2) to return all front panel key
functionality.
