CONFIGURING THE VARIOSTRING(S)

The VarioString can be configured simply, allowing charge behaviours that meet perfectly the
requirements of most lead-acid batteries. This configuration can be carried out using the DIP switches
(9) inside of the equipment to set the various configurations according to the position of each DIP
switch.
Before opening the VarioTrack, it is absolutely mandatory to disconnect all DC sources
(battery and PV) from the equipment to avoid any danger. After disconnection, it is
necessary to wait at least 5 minutes before opening the equipment, in order to guarantee
that dangerous internal residual voltages have disappeared.
It is also possible to make configurations specific to particular requirements of the system thanks to
the remote control RCC-02/03 described in the following chapter.
If an Xtender inverter/charger is interconnected (communication) to a VarioString, the
Xtender battery cycle will be imposed to the VarioString of the system. This function may
be disabled by parameter {14036}. If no Xtender is connected to the VarioString, the latter
uses its own setting. In the case of an installation with several VarioStrings, the battery
cycle is also automatically synchronized.

ONFIGURING THE EQUIPMENT BY MEANS OF THE INTERNAL
Basic settings of the device can be entered manually with the aide of the DIP switch. This setting is
only possible if the parameter {14174} permits it. The following table provides an overview of the
functions associated with each position of the DIP switch.
Position Function
1 Activation of DIP switch (of authorized by {14174})
2 to 4 Configuration of battery cycle
5 to 6 Reserved
7 to 8 Configuration of cabling of PV modules
Priority of DIP switch
The DIP switch parameter settings are prioritized over the parameter settings of the RCC.
Therefore, if the parameter {14174} authorizes the use of the DIP switch and the position 1
of the DIP switch is activated (in ON position), the DIP switch will have priority over the
parameter settings in the RCC. In this case, the following RCC parameter values will not be
taken into account:
 Parameter related to the cabling of the PV modules {14002}
 Parameters related to the battery cycle {14005}, {14009}, {14021}, {14017}, {14024},
{14008}, {14011}, {14023}
On the contrary, if the DIP switch is not activated (position 1 of the DIP switch is off or
parameter {14174} prohibits the utilisation of the DIP switch, the parameters of the RCC
related to cabling of the PV modules and the battery cycle will be utilized.
DIP switch 1 (first from the left) allows activating the settings defined by the DIP switch bank. This
activation will not be taken into account if the parameter {14174} does not allow it. When the settings
defined by the DIP switch bank are not activated, the default parameters (see list in chap.15) are
applied. These parameters can be modified by means of the remote control RCC-02/03.
If the default parameters (factory settings) are modified, the new values must be reported
in the parameter table in chap. 15 at the end of the manual which must remain on the
installation site at the disposal of the maintenance personnel.
