6.0 Troubleshooting
6.2 Performing an Inverter Reset
To perform an inverter reset (also known as a soft reset), press and hold the
Power ON/OFF button (see Figure 6-1) for approximately
fi
fteen (15) seconds
until the Charging/Inverting Status LED comes on and
fl
ashes rapidly. Once
the rapid
fl
ashing has begun, release the Power ON/OFF button. The Status
LED will go off after the button is released.
After the inverter reset is completed, press the Power ON/OFF button to turn
the inverter ON.
Some older inverter models do not allow an inverter reset. 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 a Magnum Authorized Service Center (ASC).
Info:
The Power ON/OFF button is a small momentary type switch
which operates by lightly pressing and releasing.
Info:
All adjustable inverter/charger settings in the ME-ARC (except
for the SETUP menu’s
01B Contrast
,
01C Backlight
, and the CTRL
menu’s
03 Gen Control
—which revert back to default) are saved in
non-volatile memory and are preserved until changed. This occurs
even if an inverter reset is performed, or if all power to the remote
or inverter is removed.
Figure 6-1, Performing an Inverter Reset
1. Press and hold the Power ON/
OFF pushbutton for 15 seconds.
2. Watch the Charging/Inverting
Status LED, after approximately
15 seconds it should come on and
flash rapidly (almost a flutter) to
indicate the inverter has reset.
The Status LED will go off after
the pushbutton is released.
6.3 Performing a Power Reset
To perform a power reset (also known as a hard reset):
1. Remove all AC power (utility or generator power) to the inverter.
2. Open all the inverter DC disconnects (or disconnect the positive bat-
tery cable to the inverter).
3. Ensure the inverter(s) and the remote are disconnected from all AC
and DC power (the remote display will be blank).
4. After the inverter(s) has been disconnected from all power for 30
seconds, reconnect the inverter DC disconnects (or reconnect the
positive battery cable) and resume operation.
Info:
If DC disconnects are not used, there may be a momentary
spark when the positive battery cable is connected to the inverter’s
terminal. This is normal and indicates that the inverter’s internal
capacitors are being charged.
