There is no need to reset any other functions. Smartgauge™ will remember all settings (with the exception that
status alarms will have been disabled). Refer to the flow chart headed “Re power up following power failure” for
details of the expected display at the back of the manual.
Note that re powering up Smartgauge™ results in a completely different
display from when it is first powered up following first installation (or following a
reset to factory defaults). In particular it does not carry out the System Check
(“SC”) and does not ask for the battery type. Both these parameters are stored
in non-volatile memory and will be retained from the previous use. Also note
that following re-application of power Smartgauge™ will continue to operate
as previously so, given time, it will successfully re-calibrate the charge status
of the batteries.
Note that previously set Status alarm will now be switched off. If for some reason it is required to revert the unit
to “as new” status, prior to first installation (perhaps the unit is being moved to a new installation) then refer to
Section 6.0.

SECTION 4.0 – BASIC MONITOR USE
Pressing the VOLTS button will display house battery voltage. Pressing the
STATUS button will display charge status of the house battery bank. Pressing the
BATT 2 button will show the voltage on the engine starting battery and the PGM/
Batt 2 LED will light up to indicate that engine battery voltage is currently being
displayed. To return to house battery bank display, press VOLTS or STATUS.
If no buttons are activated for two minutes, the display will go into sleep mode.
This is a power saving feature. Smartgauge™ will continue to operate, calculating
the charge status and monitoring for error conditions, alarms etc. Pressing
any button will bring Smartgauge™ out of sleep mode and the display will
operate for an additional two minutes. Sleep mode may be defeated if required
(refer to “Display Modes” at the back of the manual).
If the battery voltage goes outside the measurement range (>17 volts or <9 volts
for 12-volt systems) or (>34 volts or <18 for 24-volt systems), the volts display
will show “HI” or “LO” while the voltage remains outside of range. An “E04” error
will also be displayed and will remain displayed to alert the user to a problem – until a button is pressed. If the
battery voltage remains below the low-voltage warning for the set battery type an “E02” error will be displayed.
If the battery voltage remains above the high-voltage warning for the set battery type, an “E03” error will be
displayed.
The high and low voltage warnings described above are outside the preset limits which vary for each battery
type. “HI” or “LO” voltage displays should be responded to promptly, as battery damage or other dangerous
con- ditions may be responsible for the alerts. If power is lost an “E01” error will be displayed.
“HI” and “LO” error displays are only shown if the display is currently set to “Volts”. They are not displayed
if the display is set to “Status”. They are also not shown if the display has gone into sleep mode. But the
resulting error message will remain displayed. All error codes are displayed regardless of monitor mode.
They are shown even if the display has gone into sleep mode.
