ON/OFF Switch
The ON/OFF Switch is a momentary push-button switch that duplicates
the ON/OFF switch on the inverter. This switch also allows additional
changes to be made while in the Invert or Charge Mode.
When the inverter is fi rst connected to the batteries, the inverter and
remote go through an internal 10 seconds start-up test. After this test
is completed, the ON/OFF switch can be pressed to turn on the inverter.
Once the inverter has been turned on, momentarily pressing the ON/OFF
switch alternately turns the inverter On/Standby and Off.
On models with the Search Mode function, the ON/OFF switch can be used
to enable or disable the Search Mode. While in the Invert Mode, pressing
and holding this switch for three seconds causes the Search Mode to
alternate between Disabled (inverter always on – indicated by the INVERT
LED indicator always on) and 5W (inverter is looking for at least a 5 watt
load to turn on and start inverting – indicated by the INVERT LED indicator
blinking once a second).
On models with the battery charger feature, this switch can also be
used to put the charger in standby (disables the charger) so that all the
incoming power can be used exclusively for the AC loads. To put the
charger in standby, press and hold the ON/OFF switch for three seconds
(you must be in the Charge Mode). When this happens, the charging
indicators (BULK, ABSORB and FLOAT) will go off. To activate the charger,
press and hold the ON/OFF switch for three seconds again. When the
charger is again activated, one of the charging indicators will come 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 ON/OFF switch will not remove this AC power on the
inverter’s output.
Monitoring the LED Indicators
MM-R and MM-RC Remotes
The three LED indicators on the left side of both the MM-R and MM-RC
remotes ( s ee Figure 13) will show you the operating status of the MM
Series inverter. Monitor the indicators to determine the mode of operation:
INVERT (green) -
• On (solid)
- and the AC IN LED indicator 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 indicator is On (solid). The inverter is in Standby.
The external AC power (utility/shore power or generator) connected
to the inverter’s input is passing through the inverter to power the AC
loads. The inverter will automatically turn on to power the AC loads if
the external AC power is lost or disconnected.
• Blinks On (once every second) - The inverter is in Search Mode. The AC
load is below 5 watts (Search Watts default setting).
