ADJUSTMENT OF THE COMBI XTENDER

GENERAL
The Xtender inverter/charger has been designed to
ensure that all basic functions of an energy management
system work completely independently. In its original
version, no adjustment is usually required.
Nevertheless, in certain installation conditions, it may be necessary to adjust some operating
configurations. This is why the RCC remote control gives access to the adjustment of many
configurations and within a range largely exceeding the usual values. Use these adjustment options
with care and only with due specialist knowledge. Changing configurations is not the responsibility
of Studer Innotec. Please refer to the chapter on limitation of responsibility for more information on
this topic.
CONFIGURATION ON A SYSTEM WITH SEVERAL XTENDERS
When there is a system to which several Xtenders are connected, the changing of a configuration
is global. It will be applied to all the Xtenders connected together. To carry out adjustments on a
single Xtender, it is necessary to remove the connection cables and only keep the connection
between the remote control and the Xtender on which the different adjustment is being carried
out. It is thereby possible to configure each Xtender of a system independently. Once the
configuration has been carried out, the original connection can be re-established.
Note: If you have carried out an individual configuration, once a configuration has
been changed, the system reconnected by the data connection cable modifies
this configuration for all the Xtenders connected.
UTILISATION AND ACCESS LEVELS
The functions described below refer to the EXPERT level. Depending on the user level selected,
access to all the functions may not be possible. Refer to the chapter on adjusting the user level of
the remote control for more information on this subject.
PRE-DEFINED FUNCTIONS OF THE AUXILIARY RELAYS
The two auxiliary relays (dry contacts) of the inverter-charger Xtender are already programmed
with factory settings and can be activated with various functions. They react to different signals.
The factory settings depend on the Xtender models.
For more information on the auxiliary contacts pre-set functions, please see the inverter-charger
Xtender manual.
Caution, if your installer or supplier has done pre-settings, these pre-set functions
may have been changed.
To check the different programmings, use the function backup of the Xtender
parameters on the SD card, described there above in this manual.
MENU
The Xtender configurations are divided into several categories:
• Basic configurations
• Battery and its charge cycle configurations
• Inverter configurations
• Combi configurations (inverter/charger)
• First auxiliary contact configurations
• Second auxiliary contact configurations
• Auxiliary contact extended function configurations
• Three-phase or parallel operation configurations
