7.5.6 BCAP Setting Battery Capacity
BCAP setting tells the Dingo the effective Amp-
hour capacity of the battery being charged. This
is used by the State of Charge data screen. Long
push on BCAP to set this value. Set the battery
capacity actually expected as discussed in Section
6.4 (SOC).
BCAP’s range is 20Ah-20,000Ah. Short pushes
will increment BCAP by 20Ah until it reaches
1000 Ah. At this point, the increment increases
to 100Ah and the display changes to thousands
- i.e. 1000 is displayed as 1.0, and 1100 as 1.1.
When the display reaches 20,000Ah (shown as
20.0), it will cycle back to 20Ah (shown as 20).
It’s important to notice the difference. If it is
intended to set 20,000Ah, be careful not to set
20 Ah instead. The two appear one after the
other on the Dingo display during setting. The
only visible difference is the decimal point to
show 20,000 Ah.
7.5.7 ALRM Setting an alarm point
Long-push here to set the alarm voltage. If the
battery voltage falls below the alarm voltage, the
Dingo will activate its internal Alarm function.
This will cause the alarm led to light.(see A.2)
If the LSET / GSET settings have been configured
appropriately, this can be used to enable an
alarm light (or other type of alarm) connected to
the LOAD or ‘G’ terminal. There is no audible
alarm built into the Dingo. It can send a signal or
power to an external alarm of some kind. The
reverse function could be used to turn off a low
priority load when the battery voltage is getting
low.
System R1 Value
12V
1K,1/4W,5%
24V
2K2,1/2W,5%
48V
4K7,1W,5%
(Higher wattage resistors may be used)
R1 values are calculated to give adequate LED
brightness at low battery voltage, but not burn-
out at high battery voltages (eg. in case output
function changed by mistake).

7.5.8 RSET & DFLT Resetting and set-
ting factory defaults
Reset (RSET)
A long-push on RSET will reset the Dingo’s
microcontroller (it’s brain). This has the same
effect as disconnecting the power to the
controller except that it can be done without
removing a wire. It is a ‘warm reboot’.
Reset has the effect of clearing the day’s
Performance Data and setting the clock to 10:00
am.
Note that you will need to re-enter the current
time on the internal clock, but your other
settings and history will be retained.
Set Defaults (DFLT)
A long-push on DFLT will cause the settings
for Program 4 to be reset to the settings for
Program 1. This provides a way to return the
program 4 settings to the factory settings.
