MM-R/MM-RC Remotes Instruction Sheet

Operation

This section explains how to use the MM-R/MM-RC remotes when operating
an inverter/charger. It provides information on the ON/OFF button and the
LED indicators—that are used to show the operational status of the inverter/
charger and to assist you with troubleshooting.
MM-R/MM-RC Remotes
ON/OFF Power Switch
The remote's ON/OFF power switch is a momentary pushbutton that duplicates
the ON/OFF switch on an inverter. This switch also allows additional changes
to be made while in Invert mode or while charging.
When the inverter is fi rst connected to the batteries, the inverter and remote
go through an internal 10-second start-up test. After this test is completed,
the remote's ON/OFF switch can be pressed to turn on the inverter. Once
the inverter has been turned on, momentarily pressing the remote's ON/
OFF switch alternately turns the inverter off and on. The remote's ON/OFF
switch can be used to enable or disable Search mode. While in Invert mode,
pressing and holding this switch for three seconds causes Search mode to
alternate between disabled (inverter always on—INVERT LED always on)
and 5W (inverter looking for at least a 5-watt load to turn on and start
inverting—indicated by the INVERT LED blinking x1/sec).
MM-RC only: The MM-RC remote's ON/OFF switch can also be used to
disable the charger (Charger Standby) so that all the incoming power can be
used exclusively for the AC loads. To put the inverter into Charger Standby,
wait until the charger comes on [indicated by one of the charge indicators
(BULK, ABSORB, FLOAT)being on], then press and hold the remote's ON/OFF
switch for three seconds. When this happens, the charging indicators on the
MM-RC remote will go off. To come out of Charger Standby and activate the
charger, press and hold the remote's ON/OFF switch for three seconds again.
When the charger is again activated, one of the MM-RC remote's charging
indicators comes on to show the current charge stage.
WARNING: When any external AC power is passing through the
inverter and present on the output, pressing the remote's ON/OFF
switch will not remove this AC power on the inverter's output.
INVERT LED (green)
• On (solid)
– and the AC IN LED is off. The inverter is on. It is using energy from
the battery to supply AC power to the loads connected to the inverter.
– and the AC IN LED is on (solid). The inverter is in Standby mode. The
external AC power (utility/shorepower or generator) connected to the
inverter's input is passing through the inverter to power the AC loads.
The inverter automatically turns on to power the AC loads if the external
AC power is lost or disconnected.
• Blinks On (once every second) – inverter is in Search mode. The AC load
is below the remote's Search Watts default setting.
• Off – inverter is disabled. The inverter is not on, or will not come on if
AC power is lost or disconnected.
AC IN LED (green)
• On (solid) – external AC power (utility/shorepower or generator) is
connected to the inverter's input and passing through the inverter to
power the AC loads connected to the inverter's output.
