2.3. SETTING PARAMETERS IN THE AT10.1
2.3.1. Understanding Parameter Settings
You can change the settings of the AT10.1 while the charger is operating,
using the front panel controls. The changes you make take effect
immediately, and are saved internally. If the charger is taken out of
service, and then later returned to service, it restarts using the last values
you set. You can adjust the following parameters:
Float voltage
Equalize voltage
Equalize timer (in hours)
High dc voltage alarm setting
Low dc voltage alarm setting
Current limit value (in Amperes)
High dc voltage shutdown feature (on or off)
Your choice of equalize method is also saved internally.
When you want to change any parameter, press the EDIT/ENTER key to put
the AT10.1 into EDIT mode. The meter display flashes about once per
second, and the status indicators prompt you to adjust the respective
parameter. You adjust each parameter by pressing the UP or DOWN key
until the reading you want shows on the meter display. You can make the
display scroll up or down continuously by pressing and holding the UP or
DOWN key.
You cannot exceed certain upper and lower limits for the operating
parameters. To see what the limits are for your charger, refer to the
AT10.1 Specifications in Appendix A on page 70.
When you first press the EDIT/ENTER key, the AT10.1 prompts you to
adjust the first parameter in the list above (float voltage). When you obtain
the value you want on the display, press the EDIT/ENTER key again. The
AT10.1 saves the new setting internally, and then prompts you to adjust
the second parameter. You continue this way to adjust the first six
parameters in the list above. If you want to skip adjusting any parameter,
just press the EDIT/ENTER key again. The AT10.1 moves to the next
parameter.
When you are finished adjusting the sixth parameter (current limit), press
the EDIT/ENTER key again. The AT10.1 saves all adjustments you made
internally, and reverts to normal operation. The new settings take effect
immediately.
Edit mode ends automatically if you don't press any front panel key within
25 seconds, and any change you made to the last setting is not saved.
