Using a PT Controller: Setup

◊ Set Battery Type (Custom) – This selection allows you to individually adjust the fl oat,

absorb, and equalization charge voltage settings and to set an equalization time for your

batteries. This allows the multi-stage charging method (see Figure 10-3) to be customized

specifi cally for your batteries. Use the following Custom battery settings to determine the bat-

tery’s absorption, fl oat, and equalization voltages, and the maximum amount of time spent

equalizing.

Set Absorb Volts – Sets the level at which the charging voltage is held constant during

the Absorption charge.
Default: 14.4V (12v), 28.8V (24v), 57.6V (48v)
Range: 12.0-16.6V (12v), 24.0-33.2V (24v), 48.0-66.4V (48v)

Set Float Volts – Sets the level at which the charging voltage is held constant during

the Float charge.
Default: 13.2V (12v), 26.4V (24v), 52.8V (48v)
Range: 12.0-16.6V (12v), 24.0-33.2V (24v), 48.0-66.4V (48v)

Set EQ Volts – Sets the level at which the charging voltage is held constant during the

Equalization charge.
Note: The EQ Volts setting cannot be set lower than the Absorb Volts setting, or more than

2 volts (12v systems), 4 volts (24v systems), or 8 volts (48v systems) above the Absorb

Volts setting.
Default: 15.6V (12v), 31.2V (24v), 62.4V (48v)
Range: 12.0-16.6V (12v), 24.0-33.2V, 48.0-66.4V (48v)

Set EQ Done Time – Sets the time (duration) the battery charges at the EQ Volts setting.
Default: 4.0 Hrs
Range: 0.1-25.5 Hrs

Info: The internal timer for the EQ Done Time setting counts when the battery voltage

is equal to the EQ Volts setting, and clears when the controller status goes to Float

Charging. It clears automatically when the EQ charging fi nishes, or can be manually

cleared by selecting Float Start (under the CTRL: 04A PT CHG Ctrl menu).

Figure 10-2, Hold CV Charge Volts (PT Controller)

* Hold CV Chg VDC – This setting holds the battery voltage at the CV Charge Volts set-

ting. This is for a system that requires a constant charge voltage to be present at all times

(see Figure 10-2).
