included in the basic Settings Menu. The Advanced Settings Menu is divided into 7 submenus:

•

•
Set to Default
Shutoff Enable
The Shutoff Enable Settings submenu provides access to enable or disable the charger shutoff when Low DC
Current alarm occurs. If enabled, during Low DC Current alarm, the charger will terminate the battery charge. If
disabled, the charger will not terminate the battery charge during Low DC Current alarm. The charger will continue
charging the battery until the elapsed time is reached.
AC Volts Scale
The “AC Volts Scale” option is included for chargers that have multiple taps. This setting adjusts the scaling
used to measure the charger’s AC voltage. If the charger has a single input voltage, do not adjust this setting as
it affects the AC Low & AC High alarms.
Security
The “Security” menu allows the user to set a password to enter calibration. By default, the password is disabled.
To enable the menu password, enter the Settings Menu by pressing the Menu button on the front panel.
Navigate to Advanced
→
Security
→
Password Enable. Select YES and enter “0000”. Navigate to “Set
Password”. Set password to desired four-digit pin. Make sure to save this new number as it will be necessary to
access the menu after enabling the security feature. If the security feature is decided to be disabled at a later
time, reset password to “0000” following the same steps previously mentioned.
NOTE:
If a password is set, no changes can be made within this menu without knowing the password. In case
the password is forgotten or lost, consult factory for password reset.
Firmware Menu
The Firmware Menu allows the user to view the firmware version, as well as update the firmware if desired. The
submenus are as follows:
