Auto EQ on LV (Mode P4)
Mode P4 is an automatic Equalize cycle that is triggered when the battery experiences a sizeable discharge. When
the DC voltage drops below the Low Voltage alarm threshold and exceeds the Low Voltage alarm time delay,
Mode P4 is activated. However, the Equalize timer will only start and run the charger in Equalize mode for the
duration set in the Equalize menu after the charger has raised the battery voltage high enough to clear the Low
Voltage alarm. When the Equalize timer expires, the charger will immediately return to Float mode.

Adjusting Parameters
All equipment is shipped from the factory fully tested and set per model number. Do not make any adjustments
unless the equipment has been powered up and the settings have been determined to be incorrect. If the settings
have been determined to be incorrect, adjustments may be made as detailed below. Refer to Section 3.6 for
TPSD2 settings menu structure flow chart.
3.4.1 Settings Menu
In the Settings Menu, the user can access and change various parameters used by the TPSD2. To access the
Settings Menu, press the MENU button, select “Settings Menu”, and press the ENTER button.
Once in the Settings Menu, the user can navigate the menus with the up and down arrows. To enter a submenu,
use the ENTER button. The BACK button returns to the previous menu. When making a selection, the ENTER
button will store the value and step back. The BACK button will not save the change and will go a step back. At
any point, the settings menu can be exited, with or without saving the settings.
The settings menu is divided into 4 submenus: “Float/Eq Voltage”, “Alarm Settings”, “Advanced Settings”, and
“Return to Defaults”.
Return to Defaults
The 4
th
option in the Settings Menu is “Return to Defaults”. This option resets all user-adjustable settings to the
factory defaults. It is important to note that the factory defaults are not necessarily the correct settings for the
specific DC system. Before the charger is shipped, adjustments are made at the factory using the same calibration
procedure. If the charger is reset to default, these factory changes may be reset.
EXAMPLE:
The software default for a 130V charger is based on 60 lead cells, a 63L charger is factory adjusted
for a higher voltage. Returning to default will return the charger to a 60L voltage setting.
3.4.1.1 Float/Eq Voltage
The Float/Eq Voltage submenu provides access to change the Float Voltage and Equalize Voltage Settings.
Float Voltage Setting
The float voltage adjustment is set at the factory at 2.17 V/C (LA), 2.25 V/C (VRLA) or 1.4 V/C (NC). The Float
voltage increments by 0.1V. Select “Float Voltage Setting” and press then ENTER button. Press the UP and/or
DOWN buttons until the required voltage level is displayed. Press ENTER to store the setting or BACK to cancel.
The approximate adjustable range is as follows:
2.02 – 2.40 V/C (LA) (VRLA)
1.29 – 1.55 V/C (NC)
