Ammeter, shows the total current being
produced by the charger.
2) Voltmeter, showing the average voltage being
produced by the charger.
3) Power meter, shows the % power being produced
by the unit and the remaining power available.
4) AC power, shows the AC power is connected and
the product is live. LED flashes if power is available
but the unit is switched off (see on/off later) push
buttons. Setup and up arrow for 5 secs to activate.
5) Auto temp control, shows the battery temp sensor
is connected and operational. If sensor not
connected then the unit will default to a 20 deg C / 69
F charge curve.
6) Shows that the active PFC (Power Factor
Correction is on).
7) Fan speed control, varies depending on temp, 3
speeds.

17) De-sulphation cycle operational. For safety
reasons only available when on open lead acid
battery type.
18) Float, unit on float charge or power pack mode,
main charge complete.
19) DC output service, output working correctly.
20) DC output low voltage warning, either batteries
are very low / more power is being taken than the
charger can supply / or the charger is defective.
21) High voltage trip, the unit is defective and
tripped itself, or a high back DC voltage has been
detected, like a wind generator reg gone defective.
22) High charger temp, if the unit is positioned in too
hot an environment and over heated, or the fans
have failed.
23) Check fans, if LED on, fans are defective.
24) Case screws to access the wiring of the product.
