1.0 Overview
1.0 Overview
The ME-ARC remote control allows you to monitor and customize the operating
parameters for your Magnum inverter/charger. It is the same remote used
on all Magnum inverter/charger models in the ME, MM, MS, MS-AE, MS-PAE
and RD Series lines so there is no cross-platform confusion.
The ME-ARC50 comes standard with a 50 foot, 4-conductor (twisted-pair)
telephone cable and includes non-volatile memory (preserves adjustable
settings, even if power to the remote or inverter is removed). The Magnum
remote control includes all of the programming and operation functions in-
cluded in an easy-to-use package.
Info: This manual is for the ME-ARC with revision 2.1 or higher; see
the TECH: 02 Revisions display on page 16 for information on how
to determine your revision level.
The ME-ARC is equipped with the following features:
• LED Indicators - The at-a-glance LEDs provide the inverter/charger
status in a straightforward way.
• LCD Display - The LCD display is a 16 x 2 line (32 characters total),
alphanumeric display used for setting up the inverter/charger operation, as
well as viewing current status or fault messages.
• ON/OFF Pushbuttons (x2) - Allows the inverter or charger to be
independently and quickly enabled or disabled.
• Menu Pushbuttons (x5) - The menu pushbuttons allow the inverter or
charger to be configured to your specific system preferences. These menus
also allow simple access to menu items that can help with monitoring and
troubleshooting your inverter/charger system.
• Rotary Knob / SELECT button - The rotary encoder knob is similar
to a dash radio knob and is used to quickly scroll through and select various
menu items and settings. Pushing this rotary knob allows you to “SELECT” a
menu item, or to “Save” a setting once it is displayed on the LCD screen.

3.2 Pushbuttons and Menu Items
The five menu pushbuttons (FAVS, CTRL, METER, SETUP or TECH) allow the
inverter/charger system to be configured to your specific preferences. These
menus also allow you to access menu items that can help with monitoring
and troubleshooting your system.
Read this section to help understand the function of each Menu button and
the configurable settings - to determine if they should be changed to optimize
the operation of the inverter/charger.
3.2.1 FAVS Button
The FAVS button is short for FAVORITES. This button is similar to the Favorites
button on your TV remote, it allows you to store the most frequently used
menu items for quick reference or changes to the system.
This menu button allows 5 menu items to be stored for quick access without
having to find them within the SETUP or other control buttons. The 5 menu
items stored under the FAVS button should be the “favorite” menus most
often used.
Before changing the default FAVS menu items it is suggested that you
thoroughly review all the menu items in the menu map on pages 34 thru 37
and make a short list of the items you think you will use most often. Once
you have determined which 5 items you would like to make your favorites,
then decide in what order you would like those menus to appear under the
FAVS button. This is important since you will assign a FAVS position 1-5 for
each menu item you select to be a FAVS.
Menu items can be changed anytime under the FAVS button. Navigate to the
menu item that you would like to set as a favorite, then push and hold the
FAVS button for 3 seconds. After 3 seconds the screen will show “Select FAV:
F1” on the bottom line. Rotate the knob to select FAVS 1 through 5. Once you
have decided which location you would like the menu item to be in, press the
SELECT knob to save the menu item at the selected location.
Info: The FAVS button can be used to store menu items that would
otherwise not be accessible after a PIN has been set for the SETUP
menu.
Info: Menu “Headings” cannot be stored in FAVS, only menu
“Items”. Menu headings are identified with a number followed by
the Menu heading. Menu items are identified by a number followed
by a letter.

3.2.2 CTRL (Control) Button
The CTRL menu button contains the menus for “ACIN CONTROL”, “CHG CON-
TROL” and “GEN CONTROL”. The CTRL button gives you quick control of the
main functions of the inverter/charger without having to access the SETUP
menus in order to change operation of the inverter/charger or generator.
The SETUP menus are used to program all of the user settings for opera-
tion of the inverter/charger and accessories. Once the settings have been
programmed in the SETUP menus the features can then be enabled using
the CTRL button.
Example: In the SETUP menu “02C AC In - Time” you set the time of day
(e.g. 12AM to 8AM) that you want the inverter to connect to the incoming
AC. Once this time is set in the setup menu use the CTRL button to access
the “ACIn Control” menu and select “Time Connect”. When “Time Connect”
is selected the inverter/charger will only connect to AC when the time is
between 12AM and 8AM.

02 CHG (Charge) Control
CHG Control allows you to set the Charger Mode for Multi-Stage, always stay
in Float, Restart Bulk which restarts the Multi-Stage charge profile. Most of
the time the charger should be left in the multi-stage setting but if you want
to override this setting use the CTRL button and CHG Control menu to change
the charger profile.
Multi-Stage: This charge profile starts in “Bulk” (maximum current until
the Absorption voltage is reached), then transitions to the Absorption cycle
(Absorption cycle as determined by the settings in SETUP menu 03E Absorb
Done), and finally transitions to the final charge stage as selected in SETUP
menu 03G Final charge.
Info: Any time during the charge cycle the charger may be “forced”
into Float or Rebulk, using Force Float or Restart Bulk from the CTRL
button 02 CHG Control menu.
Info: Multi-Stage must be selected in order for the Final Charge
Stage selected in menu 03G Final Charge Stage to be used.
Multi Connect: Automatically connects to incoming AC power when the in-
coming AC is qualified by the inverter/charger (voltage is above VAC Dropout
setting and between 50Hz to 70Hz for domestic models, and 40Hz to 60Hz
for export models).
VDC Connect: Connects to incoming AC when the DC battery voltage is below
the “Set Connect Volts” setting in menu “02D AC In - VDC”, and disconnects
from incoming AC when the DC battery voltage is above the “Set Disconnect
Volts”, also in menu “02D AC In - VDC”.
Time Connect: Connects to incoming AC when the time of day is between
the “Connect Time” and “Disconnect Time” in menu “02C AC In - Time”.
AC In: Disabled - Disconnects incoming AC when selected. This setting will
prevent incoming AC from connecting to the inverter/charger.
Info: The top status line of the LCD display will alternate the inverter/
charger status with a secondary AC IN status if AC is present, but not
connecting as a result of a selection made in the SETUP menu.
Example: AC is present but AC IN -Time has been selected in the 01
ACIn CTRL menu, and the current time of day 2PM. In menu 02C AC
In-Time the current setting is 12AM - 8AM. The current time of 2PM
is outside the connect time so the inverter/charger will not connect
to the incoming AC until after 12AM. The primary status will display
“Inverting” and the secondary status will display “Time Connect” to
let you know the reason that incoming AC has not connected.
Info: See SETUP menus 02C and 02D on pages 21 and 22 for
complete explanation of VDC Connect and Time Connect menu
settings.
01 ACIn Control
AC In Control has four different conditions in which the inverter/charger will
connect to incoming AC power. Only one condition may be set at any one
time. Refer to the Setup section for information on how to use each of the
following settings.

3.0 Setup
03 GEN Control
GEN Control is used for controlling a standby generator connected to the
system using the optional ME-AGS-N. Once the ME-AGS-N is installed in the
system, the generator can be manually started and stopped or set to the auto
start and stop mode from the GEN Control menu.
Info: The ME-AGS-N, Multi Gen Start Network, version must be
installed in order for the 03 GEN Control menu to control a standby
generator. Refer to the ME-AGS-N manual for more information on
controlling standby generators.
OFF: The OFF selection turns the generator OFF if it is running from either a
manual start or auto start command. When the OFF position is selected the
generator will not start automatically.
Info: If DC power is lost to the remote, this menu resets to the
default OFF position for safety.
Restart Bulk: This selection restarts the Bulk cycle from any stage in the
charge cycle. Restarting the Bulk stage is useful when a full Multi-stage
charge cycle does not bring the specific gravity of the batteries to the
proper level.
Info: Restart Bulk will default back to the Multi-Stage once the
inverter/charger status displays “Bulk Charging”.
Info: If you have to continually restart the Bulk cycle in order to
bring the batteries to full charge, check the settings in SETUP menu
“03 Charger Setup” to make sure the batteries are fully charged at
the end of a regular multi-stage charge cycle. Check with your bat-
tery manufacture for proper battery charger settings.
CAUTION: Frequently restarting Bulk may result in overcharging
of the batteries.
Force Float: This charge profile “forces” the charger to stay in the Float mode
as long as AC is present and the charger is active. Force Float is most often
used when another source of charging such as PV, wind or hydro is available
to keep the batteries at or above the Float voltage. If AC is disconnected and
then reconnected the charger will go directly to the Float mode and will not
do a Bulk or Absorption charge cycle.
CAUTION: Using the Force Float mode may not fully charge the
batteries. Most batteries require a Bulk and Absorption charge cycle
in order to fully recombine the electrolyte in the batteries and bring
the specific gravity to the proper level. Be sure to check with your
battery manufacture before using this setting.
Info: If Silent is selected in menu 03G Final Charge Stage you can
override this selection with Force Float to temporarily Float the
batteries.

AUTO: This selection uses the settings in “04 AGS Setup” to automatically
start and stop the generator. Refer to menu 04 AGS Setup on page 29 to set
the start and stop parameters for the generator.
ON: The ON selection will start the generator by sending a “start” command
from the ME-AGS-N control module. Once the generator is started it may
be stopped by selecting OFF from the GEN Control menu, this sends a stop
command from the ME-AGS-N control module.
Info: You can manually start the generator by selecting ON from the
GEN Control menu, and then change the selection to AUTO to auto-
matically stop the generator. When the AUTO setting is selected after
the generator has been manually started it will use the STOP setting
in menu 04A “Set Stop Gen Volts” or menu 04F “Max Gen Run Time”,
whichever occurs first. This setting is useful if you want to make sure
the generator starts before you leave, but also want to make sure
the generator doesn’t run too long, thereby wasting fuel.
The start selection uses warm-up time. The stop selection stops im-
mediately it does not use the cool-down time.

3.2.3 METER Button
Pressing the METER button gives you access to different meters, which helps
determine the status of the inverter/charger and battery system.
Info: Some meter functions may not be accessible with older
inverter software. If some meters do not function check for current
inverter software.
Info: All displays will automatically returns the “Home” screen 5
minutes after the last button push; unless you are on a display in
the METER menu where the screen will stay without returning to
the “Home” screen. This feature is useful for displaying commonly
used meter readings like SOC, where it is useful to see the battery
status “at a glance”.
01 DC Meters - DC Meters display battery voltage, DC amps from the
inverter/charger and the time in charge mode. Use these meters to monitor
your battery bank.
01A DC Volts: This menu provides the DC battery voltage. The DC:
V (Volts) display provides the voltage from the batteries connected to the
inverter. The DC: V accuracy is ±1.5% with a 0.1 VDC resolution.
01B DC Amps: While inverting, the DC: A (Amps) displays a negative
number to show the battery current used by the inverter. If in charge
mode, the DCA (amps) displays a positive number to show the amount
of current delivered to the batteries. The accuracy of this display below
1 amp AC (~10 amps DC @ 12VDC) is not detected. When the current
in or out of the batteries is greater than 1 amp AC, the display accuracy
is ±20%.
01C Charge Time: This meter reads whenever the charger is in the
Bulk or Absorb mode. The meter does not accumulate time when in
Float, Charger Standby, Full or Silent mode.
Info: Once the charger leaves the absorption mode and enters the
“Final Charge Stage”, this timer is reset and will not accumulate until
the charger reenters the Bulk or Absorption charge mode.

02 AC Meters
02A Output Volts: This provides the AC voltage measurement at
the inverter’s output terminals. If inverting, this would measure the
inverter’s output voltage. If in charging mode, this would measure the
AC voltage that is passing through the inverter from the source (e.g.
grid or generator).
02B Output Hertz: While inverting, this menu displays the output fre-
quency of the inverter in Hertz. This menu provides the AC Output Hertz
on the output of the inverter at the inverter AC output terminals. When
the AC input is connected to an incoming AC source, this display shows
the frequency (Hertz) of the incoming AC source (i.e. grid or generator)
that is passing through the inverter to the inverter output terminals.
02C Load Amps: This menu displays the load the inverter is running in
the Inverting mode in AC amps measured at the inverter output terminals.
This number is always displayed as a positive number.
02D Input Amps: This menu displays the total AC amps being used by
the inverter for charging and any connected load at the output of the
inverter.
Example: If the charger is using 20A from the AC source and the load con-
nect to the inverter output is using 10A, the combined load on the incoming
AC source is 30A. So, 30A would be displayed as the Input Amps.
Info: The 02D Input Amps is determined by adding the 02C Load
Amps and the O2E Inv/Chg Amps.
02E Inv/Chg Amps: This menu displays the amps the charger is using
from the AC source.
Info: The 02E Inv/Chg Amps is determined by subtracting the 02C
Load Amps from the 02D AC Input Amps.

03 AGS Meters
03A AGS Status: There are 26 different status messages that can display
to determine what state the ME-AGS-N is currently in, but only one will be
displayed at any one time.
Info: This menu is most important to determine if the ME-AGS-
N is working correctly, or for troubleshooting an installation of an
ME-AGS-N.
Info: For any “Fault” mode listed in the status menu, please refer to
the ME-AGS-N Owner’s Manual (part number: 64-0005) for trouble-
shooting information.
AC In: The charger is connected to another source, such as grid or an-
other generator and not controlled by the ME-AGS-N.
Info: When AC In is displayed, the AGS is locked out from auto
starting.
Gen Cooldown: The stop setting has been satisfied in one of the genera-
tor start/stop menus and the generator has been disconnected from the
inverter/charger, but is still running until the cooldown time is satisfied
in menu “04J Gen Cooldown Time”.
Gen Warm-up: The generator has successfully started on one of the start
settings, but has not connected to the inverter/charger because it is wait-
ing to satisfy the warm-up time set in menu “04I Gen Warm-up Time”.

3.0 Setup
03B DC Volts-AGS: This menu displays the DC voltage measured at
pins 3 and 4 of the ME-AGS-N module. This menu is useful in setting
up the voltage start for the AGS and for troubleshooting the operation
of the AGS.
Info: The DC voltage reading in this menu may vary from the DC
voltage reading in menu “01A DC Volts” and “04C DC Volts-BMK”.
Each DC voltage reading is taken at a different place in the system
and therefore there may be wire losses or connections that make
the readings differ. It is important when troubleshooting the system
to read the appropriate related meter for each device i.e. when
troubleshooting the AGS use “03B DC Volts-AGS” for verification
and testing purposes.
03C Gen Run Time: This menu displays the time the generator has been
running since the AGS auto started the generator. This menu does not
display run time when the generator has been manually started.
Info: This hour meter resets each time the generator is stopped.
This meter is useful when trying to determine how long the generator
has been running in the auto mode if you were not present when it
started. This meter does not replace the hour meter for total hours
the generator has run.
03D AGS Temp: The menu displays the temperature of the AGS Temp
sensor (included with ME-AGS-N, but use is optional) and is helpful in
determining proper placement and operation of the AGS temp sensor.
03E Days Since GenRun: This menu displays the number of days since
the generator has last run. This menu is useful in determining if the AGS
start and stop settings are set up correctly.
Info: This meter resets whenever the generator is either auto
started, exercised or manually started. The meter reads the B+ signal
provided by the generator to the AGS module for this meter.
