1.0 BATV Menu
The BATV screen, shown at power-up, displays
the real-time battery voltage.
A long push on the BATV screen will display the
state of the charge regulation cycle.
The Battery Charge Cycle
The Dingo’s sophisticated regulation system
is designed to keep the battery fully charged
without overcharging it.
To achieve this, it uses a charge control process
with three main states. These states are Boost,
Absorption and Float. It also uses a fourth state
from time to time, called the Equalisation state
(See fig 1B.)
1.1 BOST (Boost)
In the boost state, all the charge current available
is used to charge the battery. As the battery
charges, its voltage rises. When the voltage
reaches the boost maximum voltage (BMAX) and
remains there for 3 minutes, the controller will
automatically advance to the absorption state and
then, later, to the float state.
Returning to Boost state
To get this charge cycle to repeat, the Dingo
must return to the boost state. There are three
ways that it can do this.
a. Low Battery Voltage
If the battery voltage falls below the boost return
voltage BRTN for more than 10 minutes, then
the Dingo will switch back into the boost state.
The delay is necessary to prevent large short
term loads causing unnecessary returns to Boost.
b. Programmed boost cycles (optional)
The Dingo will automatically do a boost cycle
after a set number of days (BFRQ), regardless of
battery voltage.
c. Manual boost
The user can manually set the Dingo into the
boost state (or any of the regulation states).
To manually advance to the next state, do a
long push on BATV. This will show the current
regulator state. (BOST=Boost, EQUL=Equalise,
ABSB=Absorption, or FLOT=Float). A long-
push on that state will manually advance into
the next state. Or, to return to the BATV screen
without changing the state, do a short push.
