6 DISPLAY SYSTEM
The VarioString is fitted with a “Set” button and light indicators on the front of the equipment allowing
a clear identification of the operating mode.
6.1 T
HE
“SET”
BUTTON
(4)
The “Set” button can be used to start an equalization cycle
manually if this phase is authorized by the initial settings of the
equipment. The equalization phase will be authorized as from
the beep after having pressed the “Set” button (4) for 2
seconds. The “Charge” light indicator flashes 3x as long as the
equalization phase is not completed. The equalization can be
interrupted by pressing a second time for 2 seconds: a double
beep indicates that the function has been cancelled. The
indicator (2) stops flashing 3x confirming the cancellation.
Pressing the “Set” button (4)
for 5 seconds until the
second beep turns off the
VarioString. It starts again by
pressing the “Set” button for
5 seconds.

STANDBY INDICATOR
(1)
This green indicator lights up when the VarioString is connected to a battery and ready to operate
but there is no PV voltage (at night or when no PV module is connected) or it is too low (inferior to
the battery voltage). This indicator flashes when there is a PV voltage but it is insufficient to charge
the batteries (at the beginning or at the end of the day). In order to save the battery power, the
VarioString charger turns off and goes in standby mode when this indicator lights up or flashes. It will
then consume less than 1W. The charger automatically switches on again when the sun starts shining
and PV voltage goes back above the battery voltage.
6.3 “C

”
CYCLE INDICATOR
(2)
This yellow indicator lights up when the sun is shining and the photovoltaic generator produces
enough voltage for charging the batteries. Various flashing modes enable to distinguish in what
phase the regulator is. This indicator lights up continuously during the bulk phase. It flashes 1x during
the floating phase, 2x during the absorption phase and 3x during the equalization phase.
In “synchronized” mode, the cycle state – bulk, floating, absorption, equalization - are indicated.
When the VarioStrings(s) are connected to an Xtender system and the synchronization
{14036} is activated, the manual equalization can be started only during the battery cycle
of the Xtender which will then pilot the VarioString to carry out an equalization phase. In
“synchronized” mode, the cycle state - floating, absorption, equalization - are indicated. The
“charge” LED (2) and the indicator for the amount of charge are used when the equipment
is operating.
