Switches 5 & 6: Battery Type
Switches 5 and 6 are used to select the battery type, which determines the battery charge profi le
and ensures the batteries are receiving the proper charge voltage. Select the battery type that
matches your system’s battery bank chemistry, or refer to Table 3-1 to determine the specifi c
charge voltage to use based on the battery type selected.

Switches 3 & 4: System’s Battery Voltage
Four (4) settings are available for your system’s nominal battery voltage as shown below. Use
the auto voltage detection setting (default) to determine the system voltage automatically when
the battery is connected to the PT controller; or, if the battery is out of its nominal voltage range
(i.e., highly discharged), select the setting that matches the system’s nominal battery voltage.

System
Info: The voltages shown in Table 3-1 are based on the Battery Temperature Sensor (BTS)
being disconnected, or at a temperature of 77°F (25°C). If the BTS is connected, the charge
voltage changes based on the temperature around the BTS—to ensure the batteries receive
the correct charge voltage even if they become cold or hot (see Section 4.7).
