Glossary of Terms
Absorb – Constant voltage charge stage to fill the batteries. The controller is regulating so maximum power will not be seen at
this time. The Absorb timer is also counting down to the switch to Float.
Aux – Auxiliary relays. The Classic has 2 relays: Aux 1 can be configured as a 12 volt signal or a dry relay, Aux 2 can be used
as a PWM signal output.
BLK – Bulk MPPT Mode. By using the up arrow in Tweaks under BLK you can force the Classic into Bulk mode.
Bulk MPPT - Maximum current charge stage, the Classic is trying to bring the batteries to the Absorb voltage set point. We are
basically putting all available power into the batteries.
Comm – This menu allows adjustment of things like Mod Bus port, USB Mode and MNGP address.
DvrtCnt – When enabled, allows the charge stage timers to continue to run when the diversion modes are holding the battery
voltage just below the actual set point.
Equalize - Constant voltage charge stage to equalize the batteries. The controller is regulating so maximum power will not be
seen at this time. The Equalize timer is also counting down to the switch to Float.
EQ MPPT - Maximum current charge stage. The Classic is trying to bring the batteries to the Equalize voltage set point. We
are basically putting all available power into the batteries.
Float – Constant voltage charge stage with a lower voltage than the Absorb charge point. The controller is regulating so
maximum power will not be seen at this time.
Float MPPT – Maximum current charge stage. The Classic is trying to bring the batteries to the Float voltage set point. We are
basically putting all available power into the batteries.
FLT – Float mode. By using the up arrow in Tweaks under FLT you can force the Classic into Float mode.
GF – Ground Fault, See page 22 for more info on ground fault protection.
Got Comm – Indicates a lack of communication between the display and the Classic. Consult Troubleshooting for information.
Insomnia – This, when enabled, will keep the Classic from going to Resting. This is intended for hydro mode only where you
may need time to open water valves and do not want to wait for the Classic to wake up.
LED-MODE – This selection lets you pick the function of the 6 visible LEDs on a standard Classic.
LMX – LoMax. This enables the Classic to track the input voltage all the way down to Battery voltage. When disabled the
Classic will stop tracking the input around 5 volts above the battery voltage. When the input voltage is within a couple volts of
the battery voltage the inductors can “Sing” this is usually not very loud and will do no harm.
MNGP – Midnite Graphical interface Panel. This is the graphical display included with the standard Classic controller.
Mode – This menu lets you turn the charging ability of the controller On / Off as well as lets you select the DC input source.
See page 23 for info on the Mode menu.
