WARNING
!
Equalizing produces hydrogen and oxygen gas.
Ensure the battery compartment has adequate
ventilation to dissipate this gas to avoid explosions.
View the top line of the LCD display and the
corresponding message in this section to determine
the particular Charger mode. The AC input becomes
acceptable after a minimum 10 second delay and when
the voltage is greater than the SETUP menu’s 06 VAC
Dropout setting.
•
Absorb Charging – The Absorb Charging state is the
constant voltage stage and begins when the absorb
voltage is reached while Bulk Charging. During this
stage, the DC charging current decreases in order to
maintain the absorb voltage setting.
❒ Absorb Charging appears on LCD; PWR (green) is
on solid and CHG (green) LED is typically on solid,
but may blink. FAULT (red) LED is o ff . INV (green)
LED could be on or o ff .
•
Bulk Charging – The battery charger is delivering
maximum current to the batteries. The charger will
remain in Bulk Charge until the absorb voltage is
achieved.
❒ Bulk Charging appears on LCD. PWR (green) is on
solid, and CHG (green) LED is typically on solid, but
may blink. FAULT (red) LED is o ff . INV (green) LED
could be on or o ff .
•
Charger Standby – This means the charger has been
disabled to prevent any charging, but the AC power
(from shore/utility or generator) to the AC input is still
available on the AC output. This display is shown
when the ON/OFF CHARGER button is pressed while
the AC power is passing through the inverter/charger.
❒ To enable charging again, press the ON/OFF
CHARGER button. When the charger is again
enabled, the charger will continue in the Charge
mode it last left and the CHG (green) LED will come
on solid.
❒ Charger Standby appears on LCD. PWR (green)
LED is on solid and CHG (green) LED blinks. FAULT
(red) LED is o ff , and INV (green) LED could be on
or o ff .
•
Charging – Once Charging mode has been enabled,
the unit will wait and display “Charging” to determine
the charge routine. If the DC voltage is low, the
charger will initiate Bulk Charging. If the DC voltage
is high, the charger will skip the Bulk and Absorb
charging stages and go directly to Float Charging.
❒ Charging appears on LCD. PWR (green) and CHG
(green) LEDs are on solid. FAULT (red) LED is o ff ,
and INV (green) LED could be on or o ff .
•
Equalizing – The battery charger is delivering the
equalize voltage to the batteries. Refer to Magnum's
ME-RC owner's manual for more information about
equalizing the batteries.
CAUTION
!
Ensure your batteries can be equalized—only
equalize your batteries if permitted by your battery
manufacturer or dealer. Performing an Equalize
Charge on batteries other than liquid lead acid
or certain AGM types could permanently damage
them. Refer to your battery manufacturer/dealer
for instructions on how to properly equalize your
batteries.
CAUTION
!
Ensure the DC loads will not be damaged by the
higher voltage applied to the batteries during the
Equalize Charge. If in doubt, disconnect the DC loads
to prevent damage.
Equalization charging is not available if GEL or AGM 2 is
selected under the SETUP menu’s 04 Battery Type menu.
•
Float Charging – At the end of the Absorb Charging
time, the charger reduces the charge voltage and tries
to maintain the batteries at the Float Charge voltage
setting.
❒ Float Charging appears on LCD. PWR (green) LED is
on solid, and CHG (green) LED is on solid, but may
blink. FAULT (red) LED is o ff , and INV (green) LED
could be on or o ff .
•
Full Charge – This status indicates that you have
entered the Battery Saver™ mode. This mode maintains
the batteries without overcharging, thus preventing
excessive loss of water in flooded batteries or drying
out of GEL/AGM batteries.
❒ Full Charge appears on LCD. PWR (green) LED is on
solid, and CHG (green) LED blinks. FAULT (red) LED
is o ff , and INV (green) LED could be on or o ff .
FAULT MODE MESSAGES
The Fault LED comes on and a fault status is displayed
when an abnormal condition is detected. View the LCD
display and reference Magnum's ME-RC owner's manual
in Newgle for more information.
Note: For coaches equipped with a Magnum remote
panel, Newmar uses most of the Magnum inverter remote
default settings.
Exceptions:
•
Battery Type (standard lead acid batteries are set to
"flooded" and all-electric coaches with AGM batteries
are set to "AGM2")
•
Low Battery Cutout (set to 11.2 volts)
•
Absorb Time (set to match battery capacity)
❒ 4 batteries= 1.5 hours
❒ 6 batteries= 2.0 hours
❒ 8 batteries= 2.5 hours
