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 "SET"
HE BUTTON
The "Set" button can be used to start manually an equalization cycle
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.
When the VarioStrings(s) are connected to an Xtender system and the synchronization
{10037} 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.
6.2 "N "
IGHT STANDBY INDICATOR
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 "
HARGE CYCLE INDICATOR
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.
