Selecting the Charging Mode

The TPSD has two different settings for DC output voltage, float mode and equalize mode. Float charging mode
is used for all normal battery charging needs, in the case of the TPSD the float mode can also be used for
battery elimination (directly powering the DC load from the TPSD). Equalize mode is used when it is necessary
to equalize (or balance) the level of charge across all cells present in the battery. Consult the battery
Refer to Float/Eq voltage in Adjusting Parameters section for
manufacturer for the proper equalize procedures.
Float and Equalize voltage levels adjustments.
There are two LEDs on the front panel that indicate the current mode of the charger. If the charger is in Float
mode simply press the CHARGE MODE button to switch into Equalize mode. If the charger is in Equalize mode
it will automatically switch back to Float mode after the designated equalize time, alternatively the charger can
manually be switched to float mode by pressing the CHARGE MODE button again.

3.3.1 Equalize Timer Modes

The TPSD battery charger has five different modes of Equalize charging operation. The Equalize mode can be
viewed on the charger display by pressing the down button. The equalize mode can be changed via Settings
Menu. In all of the equalize modes, the charger will immediately return to float mode if the CHARGE MODE
button is pressed.
Mode 0 (Auto EQ OFF)
Mode 0 is a manual equalize cycle and is the default setting for the charger. When the charger is set for mode
0 the equalize cycle must be activated manually. Once activated the equalize timer will turn on and the "EQ"
LED will light. The length of the timer is eight hours by default and can be changed via Customer Calibration.
After the timer cycles to zero the charger will automatically return to the float mode. Equalize mode will not
start again until it is manually activated by the user.
Mode 1 (7 Day Auto EQ)
Mode 1 is an automatic equalize cycle that activates every seven days. The length of the equalize cycle is
determined by the timer setting. The length of the timer is eight hours by default and can be changed via
Customer Calibration. After the timer cycles to zero the charger will automatically return to the float mode.
Equalize mode will restart again after seven days.
Mode 2 (14 Day Auto EQ)
Mode 2 is an automatic equalize cycle that activates every 14 days. The length of the equalize cycle is
determined by the timer setting. The length of the timer is eight hours by default and can be changed via
Customer Calibration. After the timer cycles to zero the charger will automatically return to the float mode.
Equalize mode will restart again after 14 days.
Mode 3 (30 Day Auto EQ)
Mode 3 is an automatic equalize cycle that activates every 30 days. The length of the equalize cycle is
determined by the timer setting. The length of the timer is eight hours by default and can be changed via
Customer Calibration. After the timer cycles to zero the charger will automatically return to the float mode.
Equalize mode will restart again after 30 days.
Mode 4 (Auto EQ on LV)
Mode 4 is an automatic equalize cycle that activates when the DC voltage drops below the low voltage setting
(default set at 1.98 V/C for LA) for 30 seconds or longer. The battery voltage must rise to approximately 8%
above the low voltage set point for equalize mode to activate. After the equalize timer cycles to zero the
charger will automatically return to float mode. The time delay, low voltage value, and reset percentage are all
adjustable via the settings menu.
