* If the internal fuse is broken, this shows a major error in your wiring: most probably either a short
circuit on the generator side, either a reverse connection of the battery on the solar input! In such
case, check carefully the operation of the equipment after the error has been corrected. The fuse
may consist of 4 car fuses 30A/80V or be one single blade fuse 100A/80V given the version of the PCB
you have. These fuses should be should be replaced by fuses of the same type (Littlefuse or Pudenz
FKS 166.7000.530 or equivalent for the 4 car fuses; Pudenz 156.5611.6101 or equivalent for the blade
fuse. This operation must be carried out by qualified personnel. In case of doubt, the equipment must
be returned to the supplier for a check (this fault is not covered by the warranty).

HARGING CURRENT
These indicators flash or light up continuously to indicate
the current charging range as per the table to the right. For
the VT-40 the values should be divided by 2.
The RCC-02/03 remote control allows a complete and
detailed display of the VarioTrack behaviour (see. chap.
9.1).

7 BATTERY CHARGING PROCESS

7.1 G
ENERAL POINTS
The VarioTrack has many parameters that can be modified by the user or the installer in order to
adapt the equipment to the energy system the best possible way. The factory values of these
parameters are reported in the table at the end of this manual.
These parameters can be modified by means of the remote control RCC-02/03 (optional) (see chap.
9.1– p. 41) and for some of them, a basic configuration can be done using the DIP switches (9) inside
the equipment (see chap. 8.1).
7.2 B
ATTERY CYCLE
The VarioTrack is a fully automatic solar charge regulator designed to guarantee an optimum charge
for most lead/liquid acid, lead/gel or AGM batteries.
The battery charger enters automatically into
operation as soon as the irradiation is sufficient and
the photovoltaic panel voltage is higher than the
battery voltage. The "Charge" indicator (2) lights up
or flashes depending on the on-going charging
phase.
The batteries can be fully charged by the successive
phases 1 to 4 described hereunder.

Comment
The PV voltage exceeds the max limit of 145V (75V when
battery is 12V). The equipment will stop or won't start.
has been The PV generator is probably disconnected. Check the
protection devices (fuse or circuit breaker) and/or
check the wiring. As a last resort, after making sure that
the PV generator is disconnected, check the internal
fuse (5)*
Missing battery, polarity reversal or voltage lower than
7V.
The different parts of the system's equipment must have
the same software version to function properly. Proceed
with the update following the procedure in manual
