1.0 Information 1.0 Introduction The ME-RC remote control allows you to monitor and customize the operating parameters for your Magnum inverter/charger. This remote can be used on all Magnum inverter/charger models so there is no cross-platform confusion. The ME-RC50 comes standard with a 50-foot, 4-conductor (twisted-pair) telephone cable and includes nonvolatile memory (preserves adjustable settings, even if power to the remote or inverter is removed).
2.0 Installation 2.0 Installation Review this section and the Important Product Safety Instructions on page ii before proceeding with the installation of your remote. WARNING: Installations should be performed by qualified personnel, such as a licensed or certified electrician. The installer determines which safety codes apply and ensures all applicable installation requirements are followed. Applicable installation codes vary depending on the specific location and application.
2.0 Installation 2.2 Connecting the Remote Cable The ME-RC comes with a remote cable to enable communication between the inverter and the remote. The remote cable is a 50-foot, 4-conductor, round twisted-pair, telephony standard with 6P4C (6-position/4-conductor) connectors on each end. When the 6P4C connectors are held side by side with both of the connector tabs facing the same way, the color of the conductors in each connector is the opposite from top to bottom (see Figure 2-1).
2.0 Installation 2.3 ME-RC Remote Dimensions Use the information below (Figures 2-3 and 2-4) in preparation for mounting the ME-RC remote. Directions for mounting follow in Section 2.4. ~1 ⅝" (4.1 cm) ~1" (2.5 cm) 5 ¼” (13.3 cm) 3 ¼” (8.3 cm) 3 ⅞" (9.8 cm) 2 ¾" (7.0 cm) .9" (2.3 cm) 1 ⅛" (2.9 cm) 1 ½" 5 ⅞" (14.9 cm) (3.8 cm) Figure 2-3, ME-RC Remote Dimensions 2.4 Mounting the ME-RC Remote The ME-RC can be flush mounted through an opening in the wall.

3.0 Setup Info: The voltage settings in Table 3-4 are based on the Battery Temperature Sensor (BTS) at a temperature of 77° F (25° C), or the BTS not connected. If the BTS is connected, the actual charge voltage will increase if the temperature around the BTS is below 77° F (25° C), and decrease if higher than 77° F (25° C). This ensures the batteries receive the correct charge voltage regardless of temperature.
3.0 Setup • SETUP: 05 Charge Rate – Sets the maximum charge rate allowed to charge the batteries during Bulk, Absorption, Float, and Equalize charging. The Max Charge = 0% setting helps minimize charging while continuing to allow pass-thru power. The rest of the selections are provided to limit the charge rate to the battery bank, which helps prevent battery overheating caused by charging at too high a charge rate.
3.0 Setup • SETUP: 06 VAC Dropout – Used to select the minimum AC voltage that must be present on the input before the inverter/charger switches from Inverter to Standby mode. This setting also determines the minimum AC voltage threshold where the charger disengages and the inverter (when turned on) will provide AC power from the batteries. This protects AC loads from utility outages.
3.0 Setup • SETUP: 07 Power Save – This setting allows you to turn off the Power Save feature, or to select a time (from 1 minute to 60 minutes) that determines how often the display goes into Power Save mode.

Default setting: Final = Multi Range: Multi, Float, Silent (Rebulk) Set Final Charge = Multi – The Multi setting (which is short for “MultiStage”), transitions from the Absorption stage to Float. Once in the Float stage for four hours with no DC load on the batteries, the charger will enter the Full Charge stage (i.
3.0 Setup ReBulk – When Silent mode is selected, you must also set the DC voltage set-point where the charger restarts the Bulk Charge mode. This setting should be at the lowest DC volts you want the batteries to fall before starting a new bulk charge. Typically, the lowest DC volts the batteries are allowed to fall is 12.0 to 12.2 VDC (12-volt systems), 24.0 to 24.4 VDC (24-volt systems), and 48.0 to 48.8 VDC (48-volt systems) respectively.

5.0 Operation PWR FAULT CHG INV Overcurrent Settings/Info.. Overcurrent appears on the LCD and the FAULT (red) LED is on. The PWR (green), CHG (green) and INV (green) LEDs are off. Figure 5-27, Overcurrent Fault • Overcurrent – This fault shuts down the inverter to protect internal power components. It may be caused by an excessive AC load. If the overload condition lasts for less than 10 seconds, the unit will automatically restart and resume operation.
5.0 Operation Remedy: The AC pass-thru relay is most likely stuck. A relay usually sticks because of damage to the contacts from trying to handle currents greater than they are rated. This is usually caused by not protecting the relay from handling high continuous currents, or by switching high current inductive loads. The internal relay contacts are rated to handle 30 amps AC continuously and should be protected with a breaker sized no larger than 30 amps.
5.0 Operation 5.3.3.2 Stacking Fault Messages A fault condition may occur when two inverters are stacked in series—using the stacking interface—that is not possible on a single inverter installation. Refer to the following fault messages to help troubleshoot the inverters. PWR FAULT CHG INV StackClock Fault Settings/Info.. StackClock Fault appears on the LCD. The FAULT (red) LED is on. The PWR (green), CHG (green), and INV (green) LEDs are off.
5.0 Operation 5.3.3.3 Internal Fault Messages The inverter continually monitors several internal components and will shut down to help protect itself if one of the following “internal” faults occurs. Remedy: If an “internal” fault occurs, perform an inverter or power reset to clear it (see Sections 6.2 & 6.3). After the reset, turn the inverter on. If the internal fault remains or returns, the inverter will require repair at an authorized service facility. PWR FAULT CHG INV Internal Bridge Settings/Info..

7.0 Using an AGS Module 7.0 Using a ME-AGS-N Module The ME-RC remote’s AGS menus under the AGS and TECH buttons allow you to customize and monitor the operating parameters for your autostart/ autostop generator system. To help configure and operate the AGS with your ME-RC, refer to the mini index below to direct you to the appropriate section. 7.1 ME-AGS-N Setup page 55 7.2 ME-AGS-N Functional Tests page 59 7.3 ME-AGS-N Operation/Monitoring page 59 7.4 Enabling the ME-AGS-N page 62 7.
7.0 Using an AGS Module AGS: 03 Run Time Hour Menu This menu provides the settings that determine the length of time the generator will run once it has been autostarted by the AGS. Default setting: Run Time = 2.0 Hrs Range: 0.5 - 25.5 Hrs (0.5 hr increments) How long should I set the generator run time? This depends on whether you are using the high temperature or low battery voltage autostart feature.
7.0 Using an AGS Module sensor (or thermostat control) reading is above the AGS: 04 Start Temp F setting, the generator will continue to run for a second run time period. At the end of this second run time period, the temperature sensor reading (or thermostat control) is checked again. This cycle continues as long as the AGS: 01 AGS Control menu is set to Enable (or Enable w/QT). If the temperature autostart feature is not needed, set to the OFF position.
7.0 Using an AGS Module Info: The default settings and range are automatically determined based on the connected inverter and the measured VDC. Where should I set Start Volts? When setting the VDC start voltage, it must be high enough to not over-discharge the battery, but also low enough to keep from nuisance starting the generator. Typically, start volts is set based on what is determined to be approximately 50% of the battery capacity.
7.0 Using an AGS Module 7.2 AGS Functional Tests Once you establish all the autostart/autostop settings you need, perform the following tests to verify that the AGS system is functioning correctly and the communication from the remote/inverter to the ME-AGS-N is correct. 7.2.1 Remote to Generator Communication Test This section describes how to determine the current AGS status and how to use the ME-RC remote to start the generator. 7.2.1.

7.0 Using an AGS Module 7.7 ME-AGS-N Remote Status Messages A status message may be an operational or a fault message. Access the AGS status menu (AGS button’s 02 AGS Status menu) to view the AGS’s current operating status. This menu is important when determining if the AGS is working correctly, or for troubleshooting an AGS installation. 7.7.1 AGS Remote Operational Statuses Refer to Table 7-3 for a brief description of the possible AGS operational statuses that may display.
7.0 Using an AGS Module 7.7.2 AGS Remote Start Statuses The following “Start” statuses identify the condition that autostarted the generator. If you determine that the autostart condition occurred sooner than expected (or didn’t want this autostart condition), refer to the Setup section for that condition to change (or defeat) the autostart setting. Table 7-4, AGS Remote Start Statuses STATUS DESCRIPTION Start Temp The generator has started based on the AGS: 04 Start Temp F setting.
7.0 Using an AGS Module starts or until all its start attempts are reached, which causes the AGS to go into a fault condition (indicated by a blinking FAULT indication on the remote and a solid red STATUS indicator on the AGS Module). If using the temperature autostart feature in an RV coach, set the air conditioner thermostat slightly less than the setting (04 Start Temp F menu). If using two air conditioners, set the second air conditioner thermostat 2° to 5° higher than the first air conditioner.
7.0 Using an AGS Module 7.8.2 Resolving Operational Statuses The following operational statuses can display on your remote control, and some may indicate an abnormal condition. Use the info below to resolve. • No Comm – This is a normal status if there is no AGS installed. If an AGS is installed, use the information below to determine the remedy. Remedy: If an AGS is installed, then follow these steps: 1.
7.0 Using an AGS Module Fault Gen Run – The generator successfully started and ran for more than two minutes, but the generator unexpectedly stopped by itself before the active AGS autostop condition was finished. Info: The AGS module determines the generator is running by monitoring the gen run sense voltage/signal. When this gen run sense voltage/signal is no longer available, the AGS thinks the gen is off or has stopped. Info: Gen run fault detection is not active if the generator is manually started.
8.0 Using a BMK 8.0 Using a ME-BMK This section discusses how to set up and operate the BMK using the ME-RC50 remote. It also shows what BMK menu options are available using this remote. 8.1 Understanding Charge Efficiency The first section provides information about charge efficiency and how to manually access/adjust this setting. Normally, the ME-BMK battery monitor automatically calculates the battery’s efficiency.
8.0 Using a BMK 8.1.2 Adjusting the Charge Efficiency Setting The Charge Efficiency setting determines how the battery monitor calculates the battery’s charge efficiency. The charge efficiency can be calculated automatically using the Auto setting, or can be manually programmed by the user (see Figure 8-2). The battery monitor is shipped with the charge efficiency set to Auto.

8.0 Using a BMK 8.4 Operating the BMK using the ME-RC This section explains how the ME-BMK battery monitor works, and how to use the ME-RC50 remote control to obtain battery bank information. It also covers the various LCD displays that are related to the battery monitor and the status of the Sense Module’s LED indicator. 8.4.1 How the Battery Monitor (ME-BMK) Operates The ME-BMK battery monitor uses a precision resistor known as a shunt to measure current flow into and out of the battery.
8.0 Using a BMK point. While this reference point is being calculated, the display will show “Think’n”, to indicate that the SOC reference point is being calculated. After the batteries are fully charged, the display will change from Think’n to 100% and begin to provide accurate SOC percentage values. Info: Think’n can take up to several days depending on the charge source and its ability to completely recharge the batteries (e.g.
8.0 Using a BMK • tAH Out (Total AHrs Removed) – This meter displays the total AHrs removed from the battery since the Sense Module was first connected. This display can be used as a battery service life indicator. The value is displayed in 0.1k [or 100 AHrs (“k” equals 1000)] resolution up to a maximum of 6,553.5k AHrs (6,553,500 AHrs). The displayed number resets to 0.0k when the Sense Module is disconnected from power.
