Page 12: Monitoring Your System
Dingo 2020N User Guide Monitoring your system This controllers’s advanced monitoring functions provide you with unparalleled information about your system. Here are some questions that your controller can answer: How much energy have I collected today? The top-level IN screen shows how many Amp hours have been collected today.
Page 13 Dingo 2020N User Guide The CHRG screen displays the sum of the internal and exernal currents. By doing a long push on the CHRG screen you can see how much each device contributes to the total charge. The first screen is called CINT and displays the internal charge.
Page 14 Dingo 2020N User Guide What time did the battery finish charging today? The FTIM screen in the DATA sub-menu shows the time the controller finished charging and entered the “float” state (see page 17). If the controller did not change from absorption to float, then this will show as a dash (“-”).
Page 15: The Data Menu
Dingo 2020N User Guide The Data Menu This is a quick summary of the screens in the data submenu which are reached by a long push on the DATA screen and the values stored each day by the history function.
Page 16: Retrieving Historical Data
Dingo 2020N User Guide Retrieving historical data In addition to storing today’s performance data, the controller can display information about the last 99 days of operation. Historical performance information can be accessed from the DATA sub menu (see figure 6). After a long-push on DATA, short-push until you see HIST.
Page 17 Dingo 2020N User Guide The Battery Charging Process When charging your battery, the controller moves automatically through the following charging sequence: Boost phase - In this phase, all available charge is used to charge the battery as quickly as possible. The “Boost” indicator appears on the controller’s screen.
Page 18 A long push on BATV will show the regulator state. (BOST=Boost, EQUL=Equalise, ABSV=Absorption, or FLOT=Float). A long-push on that state will manually advance the Dingo 2020N into the next state. Or, to return to the BATV screen without changing the state, do a short push. Low Battery Disconnect (LBD)
Page 19 Dingo 2020N User Guide Short-term battery voltage fluctuations caused by motors starting etc. will not activate LBD. Once the battery has recharged to a safe level, the load will automatically switch on again. This may take some time. You do not have to use this feature, and the controller will still operate effectively without it.
