Operating The Inverter/Charger - Magnum Energy ME-MR Owner's Manual

5.0 Operation
CHANGE Button
This button scrolls through the selections available under each menu heading.
Each menu restarts, so if you missed the desired selection, simply continue
to press the MENU button until the desired selection reappears.
HOME Button
Hold down the HOME button for two seconds to return to the Home screens.
Info: The MENU/HOME button can be used to reset the remote by
pressing and holding it down for 10 seconds. This is useful if the
display shows unrecognizable letters or symbols.
HOLD Button
Hold down this button for two seconds to stop the Home screens from
scrolling. Hold down again to restart the scrolling of the Home screens.
Info: All adjustable inverter/charger settings in the ME-MR are saved
in non-volatile memory and are preserved until changed—even if
an inverter reset is performed (see Section 6.2), or if all power to
the remote or inverter is removed.
Info: The ME-MR remote is only used to control an inverter. In
order to control or display a Magnum Energy accessory, you need
to use a ME-RC50 or ME-ARC50 remote control. Please refer to the
particular remote control owner's manual at www.SensataPower.com
for further information on displaying accessories.

Operating the Inverter/Charger

Turning the inverter on – Press the ON/OFF button to activate the inverter.
The inverter will either search for a load—using very little power from the
batteries—if in Search mode (see Figure 5-5), or actively inverting—using
battery power to power the AC loads (see Figure 5-3). The green INV LED is
on when the inverter is actively inverting, and fl ashes when searching.
Turning the inverter off – While the inverter is actively inverting or
searching, the ON/OFF button can be pressed to switch the inverter function
off, and this will turn the green INV LED off (see Figure 5-4).
Inverter Standby – The inverter is in standby when it is active (green INV
LED is on) and the remote shows a charge status due to an external AC
power source (utility/shore or generator) passing through the inverter to
power the AC loads. During normal operation, the AC loads are powered by
the external AC power source. However, if a blackout or brownout condition
occurs the inverter senses these conditions, transfers to Inverter mode, and
then powers the AC loads connected to the inverter.
CAUTION: If you have critical loads and are in Inverter Standby, do
not press the ON/OFF button to turn the inverter off. If the green INV
LED is off, inverter power will NOT be available to run your critical
loads should the external AC power be interrupted.
Equalize charging – Equalizing is a controlled overcharge performed after
your fl ooded (or AGM 1 type) batteries have been fully charged. It mixes the
battery electrolyte (to reverse stratifi cation) and removes sulfation that may
have built up on the plates. These conditions, if left unchecked, reduce the
overall capacity of the battery.
WARNING: Do not perform an equalization charge without following
all safety precautions pertaining to equalization—as noted in this
manual (see pages 17 and 27) and in the inverter owner's manual.
