Terminate the Self Test
To terminate the self test, push the button. The self-test can be
repeated to confirm the result.
Select Battery Type
The ProStar controllers contain a battery type rotary switch that
allows the selection of one of three charging algothrithms. Set the
Battery Type switch to
position 2
(Sealed: AGM). The switch
positions are defined as the following battery types shown in
Table 24.
Switch Position Battery Type
1 Gel : Some gel and other battery types recommend lower
regulation voltages and no equalization. This setting
regulates to 14.0V (for a 12V battery).
2 Sealed : AGM, "maintenance free" and some types of gel
batteries. Regulates to 14.15V (12V battery) with 14.35V
boost charging.
3 Flooded : Vented cells that require water to be added.
Regulates to 14.4V with 14.9V and 15.1V equalizations
(12V battery).
