CTIVATION DEACTIVATION OF FUNCTIONS
The following functions of the AJ range can be freely enabled or disabled by the user:
1. Acoustic warning of imminent stop of the inverter according to p. 6.
2. Battery lifetime optimizer function as described p. 9.
3. Imminent stop alarm by voltage flickering as described p. 6.
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
1. Acoustic alarm
Battery Lifetime
2.
(B.L.O.)
3. Alarm by voltage flickering
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 maintain the on/off key pushed on. Beyond 20 seconds the buzzer will sound
continuously to indicate the end of the sequence and will stop by the release of the key.
S
AFETY
The inverter is electronically protected. It is protected against reverse polarity by an internal fuse,
except for AJ 2100-12 inverter, which must be protected by an external fuse. The next table displays
the various possible default cases and their consequences.
Caution: the inverter is not protected against the connection of an AC source (generator or grid) at
its output. Such connection will cause a major failure and should be avoided.
Battery protection by LVD - Low voltage disconnection battery protection:
The battery is protected from deep discharge by stopping the inverter if the battery reaches a
voltage lower than 0.87*Unom (10.5, 21 or 42 V) during more than 1 minute. An acoustic signal or a
voltage flickering (if authorized) is activated during 1 minute before the inverters stops. The inverter
must then be restarted manually. It will restart automatically if the battery voltage is back to a value
higher than 1.04*Unom (12.5, 25 or 50 V).The inverter will stop immediately (with no delay) if the
battery voltage is lower than 0.75*Unom (9, 18 or 36 V).
