ELECTRICAL
SLOW FLASH
Blinks on for 4 seconds, then off for 4 seconds: Indicates
the batteries are fl oat charging and the inverter is in
Standby mode (any external AC power connected to
the inverter’s input is passing through the inverter and
powering the inverter’s AC loads).
MEDIUM FLASH
Blinks on once every two seconds: Indicates the inverter
is Inverting, using energy from the battery and providing
full power to the connected loads.
FAST FLASH
Blinks on once every second: When AC power is not
connected to the inverter’s input: Indicates the inverter
is Searching— conserving power and waiting for a load
to be turned on that meets or exceeds the Search Watts
parameter (5 watts = default setting). When AC power
is connected to the inverter’s input: Indicates absorb
charging, and the inverter is in Standby mode (the
external AC power that is connected to the inverter’s input
is passing through the inverter and is powering the AC
loads connected to the inverter’s output).
Protection Circuitry Operation
LOW BATTERY
The inverter shuts off whenever the battery voltage falls
to the LBCO (Low Battery Cut Out) level to protect the
batteries from being over-discharged. After the inverter
has reached the LBCO level and turns off, the inverter
automatically restarts after one of the following conditions
are met:
1. AC Power is applied and the inverter begins
operating as a battery charger.
2. Battery voltage rises to the LBCI (Low Battery Cut In)
level.
HIGH BATTERY
In the event the battery voltage approaches the HBCO
(High Battery Cut Out) level, the inverter automatically
shuts down to prevent it from supplying unregulated
AC output voltage. The inverter’s status LED turns off
when a high battery fault condition occurs. The inverter
automatically restarts when the battery falls to the HBCI
(High Battery Cut In) level.
This should only be performed by a qualified technician.
IMPORTANT
!
CAUTION
!
If removing all battery power (positive and negative)
to the inverter, do not remove the DC negative
connections to the inverter or any accessory until
after all positive battery connections have been
disconnected. This will prevent damage to the
inverter or to any network connected accessory.
VERY FAST FLASH
Blinks on/off very quickly/flutters: Indicates the inverter
is in EQ charge mode (requires remote to enable), or the
inverter is continuously in reset. If a remote was not used
to enable the equalize charge, then the inverter is likely in
reset. Refer to the Troubleshooting section of Magnum’s
owner’s manual to help diagnose/clear the fault condition.
ON
Solid: Indicates bulk charging, and the inverter is in
Standby mode (the external AC power that is connected
to the inverter’s input is passing through the inverter and
is powering the AC loads connected to the inverter’s
output).
OVERLOAD
During inverter and standby operation, the inverter
monitors the DC and AC current levels. In the event of a
short-circuit or an overload condition for more than a few
seconds, the inverter will shut down. To start operating
after this fault, the inverter must be restarted (turned back
on) once the inverter’s AC loads are reduced/removed.
OVER-TEMPERATURE
If internal power components begin to exceed their safe
operating temperature level, the inverter shuts down to
protect itself from damage. The inverter’s status LED turns
off to indicate the over-temperature fault condition. The
inverter automatically restarts after the unit cools down.
INTERNAL FAULT
The inverter continually monitors several internal
components and the processor communications. If a
condition occurs that does not allow proper internal
operation, the inverter shuts down to protect itself and the
connected loads. The inverter needs to be reset to start
operating.
Resetting The Inverter
PERFORMING AN INVERTER RESET
To perform an inverter reset (also known as a “soft reset”):
1. Press and hold the Power ON/OFF push button for
approximately fifteen (15) seconds until the Charging/
Inverting Status LED comes on and fl ashes rapidly.
2. Once the rapid fl ashing has begun, release the
Power ON/OFF push button. The Status LED will go
off after the push button is released.
3. After the inverter reset is completed, press the ON/
OFF push button to turn the inverter on. If the inverter
reset fails, you will need to perform a power reset
using the procedure below. In either case, if an
internal fault does not clear, the inverter will require
repair at an Authorized Service Center.
PERFORMING A POWER RESET
To perform a power reset (also known as a “hard reset”):
1. Open the inverter’s positive DC disconnect (or
disconnect the positive battery cable to the inverter).
