• Start Float – This selection restarts the Float charge cycle from any stage in the charge cycle
as long as the controller is actively charging.
Info: The Start Float selection automatically returns to the Multi-Stage setting once the
PT controller status displays as “ Float Charging ” on the router.
Info: If battery type CC/CV is chosen, the Start Float selection transfers the charger to
Silent mode (router displays “ Float Charging ”)—unless “ Hold CV Chg Volts ” is selected—
then, the charger enters Constant Current charge mode (displays “Bulk Charging”).
• Start Bulk – This selection restarts the Bulk charge cycle from any stage in the charge cycle
as long as the controller is actively charging. This setting is useful when an additional charge
cycle is required to bring the speci fi c gravity of the batteries to the proper level.
Info: The Start Bulk selection automatically returns to Multi-Stage once the PT’s status
displays “ Bulk Charging ”.
Info: If battery type CC/CV is chosen, the Start Bulk selection transfers the charger to
Constant Current mode.
Info: If you have to continually restart the bulk cycle in order to fully charge the
batteries, check the charge settings from the SETUP: 07 PT Setup menu to ensure the
batteries are fully charged at the end of a regular multi-stage charge cycle.
CAUTION: Frequently restarting the Bulk charge cycle may result in overcharging of
the batteries.
• Start EQ – This selection starts the Equalize charge cycle from any stage in the charge cycle
as long as the controller is actively charging. To enable the EQ charge cycle, press the SELECT
knob for 5 seconds at the “ Start EQ ” display to start a 5-second countdown timer. Once the
countdown has fi nished, the Equalize charge cycle starts and the lower line on the display
shows “ EQ STARTED ”. After the Equalize charge cycle has started, it will automatically stop
after 4 hours; unless “ Custom ” is selected from the SETUP: 07A Battery Type menu. In this
case, the Equalize charge continues for the duration of the Set EQ Done Time setting (default
of 4.0 hours). The Equalize charge cycle can also be manually stopped by using the CTRL: 05
PT Control menu to allow you to choose a different selection.
Note: Depending on the battery type selected in the 07A Battery Type menu, “EQ not allowed
in this battery type” may appear on the display.
Info: If the EQ charging time exceeds the Max Charge Time setting, “ PT Max Charge
Time ” scrolls across the LCD display.
WARNING: Do not perform an Equalization charge without reading and following all
safety precautions pertaining to charging/equalization per the battery manufacturer,
the inverter owner’s manual, and as noted on pages 60-61 in this manual.
CTRL: 05B PT Aux Relay
This menu allows the Aux Relay in each of the PT controllers to be programmed to automatically
engage or disengage based on battery voltage, or used to indicate a PT controller fault has
occurred. This menu also allows the PT Aux Relay to be manually engaged or disengaged. View
the PT Aux Relay’s status from the METER: 07B Aux Relay menu.
Note: If more than one PT controller is connected in your system, you will need to adjust this
setting for each controller. See Figure 12-4 for instructions on navigating this menu.
Default setting: DISENGAGED
Range: DISENGAGED, VDC, FAULT, ENGAGED, SOC
Info: When the relay is engaged, the AUX LED on the PT controller display is on
(yellow). When the relay is no longer engaged (disengaged), the LED is off.
