The top part of the display graphically shows the symbols that characterise the main function areas
offered by the system; these are called icons.
Immediately below there are two lines of alphanumerical characters (Line 1 and Line 2), which
describe the various items of the menus selected. At the sides of the LCD display, there are graphic
bars which allow the immediate viewing of the basic values (e.g. services battery level,
instantaneous current absorbed by the system, etc.).
Clearly, not all the graphic symbols shown in the previous Figure can be seen at the same time.
Icons
There are fourteen icons, which schematically represent all the control panel functions.

The parts that form an icon like the one in Figure 7 are:
The Main Body, (the tap), indicates the function, in this case the water pump;
The Secondary Body (water) shows whether the function is operating or not. In this case, inside the
icon the water can be seen coming out of the tap only if the pump is on.
The Corners indicate the icon selected at the moment through the navigation keypad.
If the Bars are lit, they indicate an alarm status or a fault related with that function group (in this
case, for example, it could be a short circuit on the pump).

GRAPHIC BARS
There are three graphic bars, Figure 12, which give an evaluation “at a glance” (as they are always
visible regardless of the operating mode we are in) of the main data concerning the camper. This
information can be examined in more detail in the associated items of the menus provided.
BAR 1 BAR 2 BAR 3
Figure 12
Bar 1 Bar No.1 Bar 1 indicates the level of the fresh water
The min. and max. levels respectively indicate: fresh water tank
Empty and fresh water tank Full. For more accurate information,
select the tank symbol and consult the menu provided
Bar 2 Bar No.2 Bar 2 indicates the battery charge level
In this case, too, more accurate information can be obtained
selecting the associated symbol and consulting all the menus it
contains.
Bar 3 Bar No.3 Bar 3 indicates the instantaneous absorption of the system by
the service battery.
Its filling takes place counter-clockwise, a higher number of
segments indicates higher absorption.
LINE 1 AND LINE 2 (ALPHANUMERICAL CHARACTERS)
The area used for showing the characters and numbers is subdivided on two lines. Their behaviour
varies depending on whether a symbol is selected or not.
If we are in navigation mode (no symbol selected), the top line will be off completely, while the
bottom one shows the time. In the opposite case, the top line shows the name of the menu item,
while the bottom one shows the alternative of it. Sometimes, if the symbol selected is associated
with a quantity (e.g. with the battery or tank), the top line shows its name, the bottom one the value
with the unit of measure at the side.

of carbon dioxide and it indicates the status of the gas solenoid valve.
GAS SENS: ON/OFF/GAS/--
The dashes (--) indicate that the sensor is not installed or is not working properly. The word ON
flashing means that the sensor is warming up, and is therefore unable to detect an alarm situation.
The word ON stops flashing when warm-up has been completed.
The word GAS appears when an alarm situation has occurred, i.e. there is a gas leak.
ALR BUZZ: ON/OFF/--
The dashes (--) indicate that the sensor is not installed or is not working properly. The ON control
enables the buzzer on the sensor to sound in the case of alarm, while the OFF one disables it.
BATTERIES
This contains the items of the menus related with the measurements of the voltage rates on the two
batteries (engine and services), of the current delivered and of the charge quantity stored.
The bars indicate that the services battery is starting to get damaged.
SERV BATT : X V
Indicates the voltage, expressed in Volts, at the terminals of the services battery.

parallel with the services battery. Initially this item of the menu is at OFF.
V MAX: X V
Indicates the maximum voltage rate, expressed in Volts, set at the services battery terminals during
charging.
PU TEMP: X °C
This gives the power unit internal temperature, expressed in degrees centigrade.
Readings below 70 °C are acceptable. Beyond this threshold, a fault situation exists. However, the
power unit begins to reduce the power delivered to prevent damage. As soon as the temperature
returns to normal, the power unit resumes normal operation with no external intervention.
FAST: ON/OFF
Allows you to set the charging cycles to be performed on the battery/ies. Initially this item of the
menu is at OFF.
N.B.: it is advisable to use fast ON only when the services battery starts having sulphatisation
problems, for partial regeneration, or in cases of extreme necessity of a quick charge, as the normal
charging cycle (fast OFF) has been designed especially for long battery life and is therefore to be
preferred.
MAINT. ON/OFF
If an external source of energy is present, it will be possible to set an alternative charging cycle
rather than the fast one. Initially this item of the menu is at OFF.
N. B.: this type of charge is to be used only in the case of prolonged vehicle stops, as it does not
carry out a true charge but compensates for self-discharging of the batteries and can be activated
only if a source of external energy is present (220V network or solar panels). It has been designed
to prevent consumption of the battery electrolyte during periods of inactivity.

This contains the items of the menus associated with the alarms present in the motorhome.
The bars and beams indicate the presence of danger.
Functions that can be activated through appropriate optional kits.
SOLAR PANELS
This contains the items of the menus associated with the solar panels.
The presence of the sun symbol (top right) indicates that the battery charger internal regulator is on.
The absence of it means that it is off, therefore any flow of energy deriving from the solar panel is
not allowed.
SOLAR P: ON/OFF
This allows you to turn the solar panels on or off. Panel ON/OFF
POWER: X(VA)
This gives the power rate, expressed in Watts, delivered instantaneously by the solar panels. An up
arrow at the top left indicates that the power is actually being used , the down arrow means that the
power is not being used (for example battery charged that does not require further charging).
The wording NOSUN indicates the lack of energy from the solar panel (night, cloudy sky).
CURRENT: X
This gives the current rate, expressed in Amperes, delivered instantaneously by the solar panels.
If, despite the presence of the sun, the current rating shows NOSUN, this means that the solar panel
is off. If necessary, turn it on using the ON control mentioned above.

GENERAL ADVICE ABOUT CORRECT USE AND MAINTENANCE OF THE
SYSTEM:
•During prolonged inactivity (over one month) of the vehicle, it is always wise
to recharge the batteries, to avoid discharging them, which could seriously
compromise the storage capacity of the batteries themselves. If solar panels
are present, they keep the batteries charged, therefore they can be kept in
parallel using the control provided on the control unit. If a connection to the
220V network is available, the maintenance charging system can be used to
compensate self-discharging of the batteries.
In systems with power unit without the main switch in the lack of external
energy sources (220V network or solar panels) it is advisable to disconnect
the positive terminal of both the engine battery and of the services battery, so
that the batteries reduce self-discharging.
•Do not use chemical substances, cleaning solvents or strong detergents to
clean the control panel. Clean using a slightly moistened, soft cloth.
•Avoid obstructing the cooling vents of the switching power unit.
•Do not allow the power supply unit to come into contact with fluids or
anything else that might get inside the container through the ventilation holes.
•Avoid pressing the control panel buttons using screwdrivers, knives, blades,
etc.
•Repairs to the electrical system may only be carried out by skilled personnel.
•Should an emergency intervention be necessary, it is advisable to disconnect
both the positive terminals of the batteries and the connection (if any) to
the 220V network or to the solar panels.
•If one of the two batteries (services or engine) is installed with the
terminals inverted, the power supply unit will undergo damage and
correct operation of it will no longer be ensured.

Practical advice for use
Set-up
To set up the power unit, you are recommended to proceed as follows:

ArSilicii v041113
17
-Connect all the connectors with the main switch at “OFF”
-Connect the plug for the outside 220V network
-Move the switch to “ON” and wait for about 20 seconds for calibration. The power unit will
then come into action supplying power on its outputs. During calibration the warning light
will stay on, after which (8 sec), except in the case of problems, the warning light should
turn off.
Taking out of service
-Move the main switch to “OFF”;
-Disconnect the plug for the outside 220V network
-Disconnect all the connectors
Battery disconnector
With the main switch at “OFF” the battery disconnection function is implemented.
NB. Also when the main switch is at “OFF” the functions that make the parallel of the services
battery with the engine battery and the fridge supply remain operational.
Do not:
-Connect or leave the solar panel connected in the absence of the service batteries;
-Carry out any maintenance with the outside 220 V network connected.
Solar panel
-See application note.
Warning Led L1 in Figura 2 (new feature)
-At switch on this Led stays on for approx. 8 sec. It then turns off and the system will deliver
power on the output.
-If the voltage of the service battery falls below 10.5V the Led flashes rapidly to alert that we
have entered the so-called Brownout zone, i.e. the user is alerted that the battery is running
low. This condition will end if the battery voltage returns above 10.8V and consequently,
the Led turns off. If the battery voltage falls further to below 9.5V the so-called Blackout
zone is reached and the red Led flashes at a lower frequency. During this condition, though
the functions associated with D+ at 230VAC and the solar panel remain active, the power
unit cuts off the power to its output and will be able to resume powering only when the
battery voltage has returned to 12.5V.

Application notes for installing solar panels.
Introduction
These notes refer to the installation of solar panels on motor caravans fitted with power supply unit
Model AL-320X
General Section
The electric system power supply unit developed by ArSilicii (models . AL-320X) can control the
various sources of energy available on the motor caravan.
The energy flows are summarily shown in Figure 3
Figure 3 "Overall view"
In Figure 3 the following items are shown:

The power unit is therefore capable of charging the batteries, performing the charging cycle chosen
by the user, depending on the source available.
In the particular case of the solar panel, no further devices are needed between the solar
panel and the power supply unit because, as mentioned, the charge adjustment functions are already
carried out by the power supply unit itself.
The power supply unit supports panels also up to 300W, unlike the previous version that was
indicated for 120W.
Case 1 : Assembly of a single Panel
Make sure the panel is fitted with a non-return diode and if not, install one.
If a single panel is fitted, it should be connected as shown in Figure 4:
In the figure below the panel is understood to be fitted with non-return diode
J5
10 A +-
Figure 4 "Assembly of a single Panel"
It should be noted that along the cable of the positive terminal, near the power supply unit, a fuse
of adequate amperage is fitted.
How should the fuse cut-off power be chosen?
Clearly, the fuse should be chosen in accordance with the normal operating current and the diameter
of the cable connections used.
Example:
For a generic 100 W panel the maximum current (Short Circuit Current) indicated by the
manufacturer can be approximately:
Short Circuit Current = 7 A
