Status Monitoring

The inverter portion of your RV or Legend Series II inverter/charger can be turned Off or On

using the remote control. The standby charger in your inverter/charger system is

automatic always ready and available for charging whenever AC power is available.

The RC7(GS) remote features several meters that enable you to monitor operating

conditions of your power center. These meters include Average Shunt Amps, Battery

Voltage, Inverter-Charger Current, AC Input Voltage, AC Output Voltage, AC Input Amps

(GS only), Pass Through Amps (RC7 only), Battery Temperature, Transformer Temperature,

FET Temperature, and Estimated Battery Capacity, as well as Battery State of Charge,

Time Left to Run, and Time Left to Charge.

The RC7 & RC7GS remotes enable you to turn your inverter On or Off at the push of a

button on the faceplate. You can use the RC7 to configure the inverter/charger to your

specific system and preferences including battery capacity, battery type, charger rate, low

battery cutoff, AC voltage dropout, shore power amps, external shunt, fuelgauge cutout and

display contrast. In addition, the RC7GS enables you to start and/or stop your genset

automatically or manually, specify generator make and model, and set a ‘quiet time’ during

which the genset will not start automatically.

These remotes monitor operating conditions including AC supply, inverter operation,

charger operation, battery condition and generator condition (GS only).

1. Select an appropriate location to mount the RC7or RC7GS. Use the dimension drawing

provided to prepare the mounting surface, or install in a standard ‘double-gang’ outlet box.

2. Place the On/Off switch on the front panel of the inverter to the Off position and

disconnect AC power. Repeat whenever connecting the remote.

3. Insert the remote communications cable into the RJ11 port on the inverter/charger

marked 'Remote Control'. Do not substitute an ordinary telephone cable. Insert the other

end of the cable into the RC7.

4. Wait for the LCD to display the message "Waiting for AC".

5. Place the On/Off switch on the inverter to the "On" position. (the remote will not operate

the inverter with this switch in the "Off" position).

6. Connect the inverter to an AC power source. After a brief delay, the RC7 will display a

system status message similar to the illustration that follows:

To configure your RC7, enter the Setup menu as instructed previously. Search Sense is the

first selection in the menu. To change the setting, scroll through the menu choices by

pressing the Right arrow key labeled Settings. If you pass the setting you desire, just keep

pressing the Settings key until the selection reappears. The available choices are shown

below:

Search Sense will be disabled when you select Defeat. When you select any other setting,

a load of at least the selected watts will be required to activate the inverter. See your

inverter/charger owner’s manual for a detailed discussion about Search Sense loads.

When the Search Sense setting that you desire is displayed, press either the Up or Down

arrow key to move on to another menu selection.

The Automatic Low Battery Cut Off (Auto LBCO) prevents the inverter from draining your

batteries below10.51 volts. When enabled (On), the inverter will shut off when the battery

voltage drops to 10.51 volts. When disabled (Off), the inverter will draw from the battery

until voltage drops to about 8.5 volts, then shut off. When AC power is available, the

inverter/charger will automatically reset and begin charging the batteries..

To set Auto LBCO On or Off, enter the Setup menu by pressing and holding both the Up

and the Down arrow at the same time until the screen display clears. Then press the Down

arrow until the Auto LBCO item appears. Press the Settings button to change the current

selection, then scroll to the next Setup menu item. The Auto LBCO display is shown below.

Battery capacity refers to the reserve capacity in amphours of your battery or battery bank,

not the cold cranking amps. The RC7 enables you to specify the approximate reserve

capacity of your system so that it can more accurately calculate the battery state-of-charge

(SOC) and remaining time-to-run. The RC7 automatically estimates your battery capacity

and adjusts itself over several charge/discharge cycles, but setting the capacity will assure

more accurate initial SOC and time-to-run calculations. The default setting is Auto.

To optimize the battery charger’s performance, you can specify the type of batteries that

you are using: gel cell or liquid lead acid. The menu is shown below:

Charge Rate

Vac Dropout

Shore Power Amps

RC7 Setup

You can specify the battery charger’s maximum output current using the Charge Rate

menu. The default rate is 100% of the inverter/charger’s maximum charge rate. Consult

your inverter/charger Owner’s Manual for information specific to your system. The Charge

Rate menu is shown below:

Your inverter/charger monitors the voltage level of the AC power supplied to it. You can

select the AC voltage at which the inverter switches from AC power to DC power. This

assures a continuous supply of quality alternating current to your electrical loads. The

lower the settings you select, the less frequently you inverter will switch from AC to DC.

The range is from 40 to 100 volts. The selections are shown below:

The shore power amperage setting is selectable. Your inverter monitors the AC power

being drawn by both the battery charger and the AC loads connected to the inverter. If the

current draw approaches the circuit breaker’s rating, the battery charger will reduce the

amount of current going to the batteries. This control can also be used to prevent

overloading of backup generators if they are used to charge the battery as well. Adjust this

setting to match your generator’s maximum continuous output. This is usually lower than

the rating of the circuit breaker provided on the generator’s output. The Shore Power Amps

menu is shown below.

The RC7 LCD screen displays system status and error messages during normal operation.

You can choose a rolling display that includes state-of-charge, time left to run,and time left

to charge.

Alternatively, you can choose the default system status message; any one of these, or a

power saving option that shuts the LCD and LED display off after 5 minutes without a key

press or a new error message. The default is the Last Key selection, which displays the

last system status message that you select after you exit the Setup Menu. The RC7 Setup

menu is shown below:

This menu item enables you to adjust the contrast of the screen display to accommodate

changing lighting conditions. Less contrast may be preferable in brighter lighting conditions.

The default setting is Max Contrast. The menu selections are shown below:

When two inverter/chargers are utilized in a system, an external shunt will be required in

order for the fuel gauge feature of the RC7 remote control to give accurate information

about the charge state of the battery bank. See your inverter/charger Owner’s Manual for

instructions on installing an external shunt. The External Shunt menu enables you to

configure two RC7’s for use with two inverter chargers. The RC7 connected to the external

shunt becomes the ‘fuel gauge’ unit. Select the appropriate response from the following

menu items:

Use the Fuelgauge Cutout menu to set the voltage that the battery manufacturer specifies

or you define as zero per cent State of Charge ( 0% SOC) with no load. This is the voltage

at which the battery has zero reserve amphours remaining. The fuel gauge meter uses this

number to determine the 50% battery state-of-charge voltage. The factory setting is 11.4

volts. The menu selections are:

These messages will be displayed whenever the RC7GS has been setup to start the

generator at a specified condition, and that condition has arisen.

When the initiating condition (SOC or battery voltage) has occurred, the ‘ ’

message will be displayed for approximately two minutes awaiting a change in the condition

or a manual override. If neither occurs, the RC7GS will attempt to start the generator and

will display the ’ ‘ message.

When the generator starts, there will be a brief delay to allow the genset to reach operating

speed and allow to synchronize voltage with it; then the ’ ‘

message will be displayed.

In the event the genset does not start within thirty-seconds, a two-minute starter cool-down

period will occur and the ’ ‘ message will be displayed after which another

attempt to start the genset will occur. This cycle (cranking - cooldown - cranking) will repeat

three more times for a total of four attempts to start the genset over a 12-minute period.

If the genset has not started after four attempts, the RC7GS will display the ’

attempts to start the genset will occur. Correct the generator starting problem and manually

start the genset. You can reset it using the Setup menu

Whenever the RC7GS Gen Start function is configured to Auto Start your generator under a

specified condition and that condition occurs during the specified Gen Quiet period, the

LCD will display the Gen Quiet Fault message, the Error LED will be lighted, and the remote
