Mastervolt MASS COMBI 24/2500-60

TROUBLE SHOOTING
40 May 2010 / Mass Combi 12/2500-100; 24/2500-60; 48/2500-35; 48/5000-70 / EN
Mode Illuminating LEDs Explanation / Possible cause What to do
4 = solid yellow
8 = solid red
Short circuit error. The battery
voltage is far too low. The charger
reduces the output current till 25%
of the maximum output current.
Check the batteries and the wiring.
5 = solid yellow
8 = solid red
Overheating error. The charger
current is reduced to zero in case of
extreme overheating until the Mass
Combi is cooled down.
Check whether the air flow of the Mass
combi is blocked or whether the ambient
temperature is too high.
2,3,4,5,6 = blinking yellow,
8,9 = solid green
Equalizing mode is activated See chapter 6.2.6
2 = blinking yellow
3,4,5,6 = solid yellow
8,9 = solid green
Charger runs a compensation cycle
for self discharge of the batteries
Nothing. See figure 28 for charging
characteristics
1 = solid yellow
7 = solid red
Overload error. The inverter is
loaded with more than 2500W
Reduce the connected load by switching
off some equipment.
3 = solid yellow
7 = solid red
DC voltage error. The battery
voltage is too high or too low.
Check the batteries and the wiring.
4 = solid yellow
7 = solid red
The inverter output voltage is less
than 180V AC.
Reduce the connected load.
5 = solid yellow
7 = solid red
Overheating error. The inverter is off
because of high temperature.
Reduce the connected load and let the
Mass Combi cool down.
7 = flashing red The inverter is permanently off until
a manual reset by means of the
main switch.
Disconnect all loads and restart the Mass
Combi by switching the unit manually off
and on with the main switch.
6 = flashing yellow
7 = solid green
The battery voltage is running too
low, but the inverter is still on.
Check the batteries. The inverter will switch
off if the battery voltage stays low
Inverter
3,4,5,6 = solid yellow
7 = solid green
2 = flashing yellow
The battery voltage is running too
high, but the inverter is still on.
Check the DC-input voltage. The inverter
will switch off if the battery voltage rises too
high
