14.13.5 Automatic restart {1129}
In the event of an anomaly on the installation, the combi Xtender stops automatically. Depending
on the seriousness of the fault, when this disappears, the Xtender may restart automatically without
any user intervention (fault confirmation). The following functions allow the events for automatic
restart to be defined.
After battery undervoltage {1130}
Number of battery undervoltages allowed before final stop {1304}
Leadtime to counting the battery undervoltages allowed before final stop {1404}
Number of critical battery undervoltages before final stop {1305}
Leadtime to counting the critical battery undervoltages allowed before final stop {1405}
After battery overvoltage {1131}
After inverter or Smart-Boost overload {1132}
Delay to restart after an overload {1533}
After overtemperature {1134}
Whatever the restart method, the event is recorded in the event history so that it can
be called at any time.
14.13.5.1 Number of battery undervoltages allowed before final stop {1304} and
Leadtime to counting the battery undervoltages allowed before final
stop {1404}
If battery undervoltage faults occur to your system, the inverter and Smart-Boost functions are
deactivated in order to protect the battery against deep discharges.
These functions can be reactivated automatically if the fault disappears. With the parameter {1304},
you can adjust the number of the faults before these functions are definitely deactivated. In this
case, an intervention is necessary to reactivate these functions (fault acknowledgement).
The duration parameter allows setting the time during which these faults can be repeated.
Once this duration has come to an end, if the number of faults is not reached, the counter goes back
to 0 and the faults can occur again.
To cancel the automatic reactivation, set 1 for the number of battery undervoltages
allowed before final stop.
For a permanent automatical reactivation, set 0.
14.13.5.2 Number of critical battery undervoltages before final stop {1305} and
Leadtime to counting the critical battery undervoltages allowed
before final stop {1405}
The critical battery undervoltages can also be automatically acknowledged in case of undervoltage
disappearance. Like for the undervoltages (see previous paragraph) you can adjust the number of
restarts of the inverter and Smart-Boost functions once the fault disappears.
14.13.5.3 Delay to restart after an overload {1533}
If the function inverter is stopped after an overload (power of the users too high) the inverter will do
one or several attempts to restart. You can use this parameter to determine the time between the
restart attempts (in seconds).
This gives you more time to disconnect the users which caused the overload.
