The table below will show you the different causes of inverter stopping
The state<activated> or <deactivated> of the functions is indicated by the buzzer with a continuous push on the on/off key after a duration
given for each function as per the table below:
single <beep> short=function activated
Double <beep> short = function deactivated
Function
Acoustic alarm
Bttery lifetime optimization
(B.L.O.)
Alarm by voltage flickering
Duration of impulse(onto on/off)
5 seconds
10 seconds
15 seconds
Default setting
Activated
Deactivated
Deactivated
The state is reversed if the on/off key is released within 2 seconds following the buzzer sound.
To consult the state of functions without having any effect on them or changing their programming it is possible to main the on/off key pushed
on. Beyond 20 seconds the buzzer will sound continuously to indicate the end of the sequence and willstop by the release of the key
Safe
The inverter is electronically protected, It is portected against reverse polarity by an internal fuse,The nxet table displays the various
possible default cases and their cnosequences
Caution: the inverter is not protected against the connection of an AC source(generator or grid) at its output. such connection wil
cause a major failure and should be avoided
Battery portection by LVD-low voltage disconnection battery protection:
The battery is protected from deep discharge by stopping the inverter if the battery traches a voltage lower than
0.87Unom.(10.5 or 21V)during more than 1 minute. An accoustic signal or a voltage flickering(if authorized) is activated during
1minute before the inverters stops, the inverter must then be restarted manually, it will restart antomatically if the battery voltage is
back to a value higher than 1.04*Unom(1 2 . 5 or25V),the inverter will stop immediately(with no delay) if the battery voltage is lower
than 0.75*Unom(9 or 1 8V).
CAUSE CONSEQUENCE SOLUTION
Low battery voltage
voltage<0.87*Unom
Deep discharged
battery voltaeg<0.75*Unom
Overheating
Battery overvoltage 1.33Unom
Short circuit at the output
Overload
Battery reverse polarity
inverter temporary stopped ,the green
indicator blinks
Inverter stopped
Inverter temporary stopped the green
indicator blinks
Inverter stopped
Inverter stopped
Inverter stopped
Internal fuse broken down
Automatic restart when the battery
voltage rises at 1.04*Unom
The inverter should be manually restarted
Inverter should be manually restarted when
the battery has reached=0.87*Unom
Automatic restart when the temperature
reaches the normal range
Wait until the battery voltage reaches the correct level
Push the ON/OFF button to reactivate the
inverter 1.2*Unom
Eliminate the short circuit
Push the ON/OFFbutton to reactivate
the inverter
Use the inverter only in the range of its
nominal power. Regular use in overload
power diminishes the lifetime of the inverter
Push the ON/OFF button to reactivate the inverter
