Standard Classic programming
Commissioning the Classic (Quick Start)
The Classic will enter into the Quick Set screens upon initial power up. If the Classic does not enter into
the quick set or you want to restore to Factory Default follow these steps to initiate a Quick Set.
 With the power off to the Classic Hold the left and right arrow buttons down.
 Turn the power on to the Classic and continue to hold the arrow buttons until the setup screen is
displayed.
 Answer the questions on the next few screens to complete the Quick Set.
Battery Charge Stages and Meanings
Bulk MPPT
This stage of the Classic means that the Classic will be putting out as much current as it can to raise the
battery voltage to the absorb voltage set point. This is also known as Constant Current Mode.
Absorb
This stage means that the Classic will maintain the Absorb set point voltage until the batteries are charged.
This stage is terminated at the end of the Absorb time or the End Amps set point, whichever is reached
first. At this stage the Classic is not putting out maximum current, as that would increase the battery
voltage over the Absorb set point. This is also referred to as Constant Voltage Mode.
The absorb time is proportional to the bulk time (i.e. the time bulk takes to reach the absorb voltage).The
battery is considered ―full‖ at the end of the absorb charge cycle.
Float
A Float cycle follows after the Absorb cycle is completed; Float is displayed on the screen. Battery
voltage is held at the float voltage set point.
Equalize
The Equalization function can be manually initiated or can be set up to Auto Equalize. The intent of an
Equalization charge is to bring all battery cells to an equal
voltage by a controller deliberate overcharge.
The goal is to return each battery cell to its optimum condition through a series of voltage controlled
chemical reactions inside the batteries.
Resting
―Resting‖ will show on the display when the Classic is not charging the batteries, this is typically due to
low light. If the Classic is resting and should not be, make sure Aux2 is not set to a logic input that is
forcing it into resting.
Mode is OFF
The Classic is unique in that it has multiple charging algorithms for just about any DC input. Because we
support such a wide variety of DC inputs we have also added a software ―ON‖ and ―OFF‖ feature. This
software ―Switch‖ basically turns the relay off, effectively disconnecting the input source so the Classic
