Steca Xtender
Installation and Operating Instructions 723.932 Xtender V0.511 Seite 26
7 Control 7.1 Main on/off control
This switch (1) interrupts the electronic supply and all the Xtender peripherals. The residual
consumption on the battery is therefore less than 1 mA.
The ON/OFF switch is used only for the complete stoppage of the whole system.
7.2 Display and control parts
The Xtender has a ON/OFF button and light indicators
at the front of the device, allowing clear identification of
the operating mode.
(41) The ON/OFF button allows the startup or complete
stoppage of the system such as it has been
programmed. In the systems comprising several units,
each unit is started or stopped individually. For a
simultaneous startup of all the units use the dry contact
control (see chap. 0 – p. 23) or the ON/OFF button of
the RCC-02/03 remote control.
Even when the equipment has stopped,
dangerous voltages may be present at
the Xtender input.
(42) This indicator lights up when the equipment has
been stopped manually using the ON/OFF button (41).
It also allows the cause of an unintentional stoppage of
the device to be indicated via the different flashes, the
imminence of a stoppage or the temporary limitation of
its performance.
The table below describes the type of fault according to
the number of flashes on the indicator (42)
Indicated alarm Comment
1x (Imminent) stoppage as a
result of low battery voltage. If the device has not yet stopped, it is recommended to
disconnect all non-priority consumers and/or start up the
generator. If the Xtender has stopped it will restart
automatically when the battery voltage has reached the
correct value again {1110}. It can be restarted manually
using the ON/OFF button (41) as long as the battery voltage
is higher than the critical threshold {1488}.
See also chapter 6.2.8 – p. 22.
2x Stoppage due to overload in
the equipment, due to either
a short-circuit or too high a
load for the inverter.
In this event the equipment will make several attempts
restart {1133} every few seconds and will stop if the overload
remains (see chap. 6.2.8 – p. 22). It is vital to eliminate the
cause of the overload without restarting. Restarting is carried
out manually by pressing the button (41).
3x Decrease in the rated output
of the device due to a too
high internal temperature.
This may be due to too great a load for the device, at too
high an ambient temperature or counteracted or obstructed
ventilation. The power output of the device will therefore be
limited to around 50% of the Pnom. including in charger
mode or smart boost mode. 6.2.8 – p. 22.
4x Battery voltage higher than
the maximum limit set by the
configuration {1121}.
Check the cause of this excess voltage. The equipment will
restart automatically when the voltage falls below the
threshold value {1122}.
