INSTRUCTIONS FOR
POWER-SWITCH BATTERY CHARGERS (PSW)
The battery chargers of the PSW series use high frequency technology,
which enables them to be compact, light and efficient and to have a constant
and repetitive behaviour. An inner microprocessor enables automatic
recharging of batteries and stores the behaviour of the battery charger during
its use.
This device has been developed for a professional use.
For best results and safety, the user is required to read, follow and keep
these instructions carefully.
The manufacturer is not responsible for any damage due to improper use.
BATTERY
The battery voltage has to correspond to the PSW rated voltage (see rating
data, for example 24V).
A label on the PSW indicates the correct rechargeable battery type. Check
that it matches the features of your battery. If necessary, it is possible to
change the programming in order to adapt the PSW to your battery.
Make contact with the supplier in order to carry out this change.
INSTALLATION
To ensure maximum safety, installation has to be carried out as indicated
by the manufacturer.
Any work on the charger must be carried out by qualified and authorized
technical personnel.
Never open the metal box: it is not necessary to get inside for installation.
WARNING: There is risk of electric shock inside the box.
After unpacking be sure that the device is in perfect condition; in case of
doubt, do not use it and contact the supplier.
It is better to install the PSW indoors, in a room free of humidity, acids or
dust, with room temperature between 0 - 40° C. During use do not obstruct
the ventilation holes. Any overheating of the PSW will reduce the output
current; if overheating continues, charging will be stopped (see SPECIAL
SIGNALS).
FIXED INSTALLATION: considering the small weight, in order to avoid
damage due to being dropped, we recommend fixing the PSW firmly to the
wall. For fixing see Fig. 3.
ON BOARD INSTALLATION: fix the PSW horizontally in a well protected
area of the vehicle, which allows dissipation of the heat produced (FIG. 4).
It is better to use vibration mounts. Connect the PSW cables directly to the
battery poles; never use existing cables of the vehicle equipment.
Any non-compliance with this rule can cause malfunctioning or damage
which cannot be attributed to the manufacturer.
More information is available in the ADDITIONAL FUNCTIONS section.
ELECTRICAL SUPPLY
Be sure the rating data of the battery charger is compatible with the mains
power supply (single-phase, voltage, frequency, power). Plug into a socket
equipped with protections that comply with local standard regulations. If you
have to use an extension cable, contact the manufacturer for correct technical
information. The replacement of the supply cable has to be carried out only
by qualified personnel.
BATTERY CONNECTION
Respect the polarity: red wire to + and black wire to -.
Incorrect connection does not cause any damage, but prevents the charging
cycle from starting.
Do not use extension cables without the manufacturer's approval.
USE
Connect the battery and the power supply cable. LEDs light up for 2 seconds
(PAN. 1), then only the CHARGE LED stays on (PAN. 2). If this does not
happen, check the connection on the battery and supply.
The PSW is unable to activate the charging if the voltage of the battery is
lower than 1 V/Cell (i.e., 12V for a 24V battery).
If everything is functioning properly the charger performs the whole charge
and stops with the STOP LED illuminating (PAN. 3).
The time of charge depends on the discharge level, the battery type and
the programmed charge cycle.
For lead acid, gel or AGM batteries, 80% discharged, the whole recharge
lasts 10-14 hours.
For lead acid batteries it is possible to reduce the time to 7-8 hours by
programming the fast cycle.
Shorter times are possible if the battery is less than 80% discharged.
Longer times are possible if the battery is more than 80% discharged.
EQUALIZATION
Completed the Phase 2, the microprocessor can activate the equalization
charge, depending on the programming. Ask your installer how the charger
was set. This phase is composed of series of charge pulses alternating with
periods of waiting. During the charging pulses, the CHARGE LED will flashing
(Pan.4), during the waiting periods, the "Stop" LED will light (Pan.3). The
equalization charge is useful for maintaining balanced all the battery elements.
SPECIAL SIGNALS
When the microprocessor detects a problem, it stops charging and signals
this by flashing the two LEDs (PAN. 5). The different possible problems are:
- overheating: the thermal conditions interrupt the current in order to avoid
damage
- defective battery: the voltage trend shows a possible failure of the battery
- incorrect battery: the battery has a higher voltage than the charger (36V
GB
battery on a 24V charger).
In order to determine the kind of problem it is necessary to read the internal
PSW data memory (see DATA MEMORY section).
If the two LEDs remain lit (connecting the battery) (PAN. 9), means an
internal problem has occurred. Only the manufacturer can solve this problem.
CHARGE INTERRUPTION
Power failures interrupt charging and all LEDs go out (PAN. 6); when the
power supply is resumed charging starts again at the point it was interrupted.
If charging has to be interrupted for any reason, switch off the PSW using
the button provided and disconnect the battery.
To activate STOP, hold the button down until the STOP LED begins to flash
(PAN. 7).
To interrupt the charge if the PSW is fitted on board, disconnect the mains
supply and use the vehicle.
Never disconnect the battery if the charger is supplying current, as the
resulting spark could ignite the gases produced by the battery and cause
an explosion.
For best charging, disconnect the battery only when the microprocessor
indicates STOP (PAN. 3).
HOLDING
If you leave the PSW on line and connected even during long periods of
inactivity, it is possible to maintain a 100% charge level.
At the end of a charge cycle (device indicating STOP – PAN. 3) the holding
starts: when the battery voltage falls under a minimum level, the PSW goes
into operation and supplies a small current in order to let the battery voltage
reach a maximum level and then it stops. These charging pulses can be
repeated indefinitely when necessary. The length of each pulse and the
time between pulses depends only on the battery condition. During charging
pulses the display indicates STOP (PAN. 3).
If charging is interrupted by the pushbutton (PAN. 7), holding does not start.
We advise not to leave the PSW connected to the battery without mains
supply for more than one week. Without mains supply, the PSW absorbs
energy from the battery and may cause its total discharge.
DATA MEMORY
The internal microprocessor can store a remarkable quantity of information
throughout the life of the PSW. This information can be read only through
the suitable terminal (MULTIPROGRAMMER) connected to the programming
connector shown in Fig. 2.
Contact the supplier for the purchase of a MULTIPROGRAMMER-CLIENT.
Reading this information helps detect the problems and their cause.
It will be easily understood whether they are caused by a malfunction of the
charger or the battery.
It is also possible to understand whether the problems are caused by the
non-compliance of the user with the rules. Be particularly careful when
reading the user's handbooks.
ADDITIONAL FUNCTIONS
This section contains directions for the PSW when fitted on board.
When the PSW is assembled on board, the LEDs are often not visible.
It is possible to add an optional external display (VISLED) in order to place
the control LEDs in a visible area. Ask your supplier for this and connect it
to the auxiliary connector indicated in Fig. 1.
The PSW has two auxiliary contacts , which must be correctly connected
to the vehicle equipment, with following functions:
- mains presence: the contact is normally closed; it opens when the PSW
is supplied for charging. It has to stop the vehicle during the charging phases
(contacts 1 and 7 of the auxiliary connector to be seen in Fig. 1);
- discharged battery: the contact is normally closed; it opens when the battery
voltage is lower than the programmed value. It has to stop the vehicle when
the battery has exhausted 80% of its energy (contacts 3 and 5 of the auxiliary
connector to be seen in Fig. 1).
When the PSW operates on a discharged battery, it illuminates the BLOCK
LED (only visible on the outer display VISLED) and it stops the vehicle.
In order to remove this block it is necessary to carry out a complete recharge.
The PSW will signal to the user when technical maintenance is due. When
this happens, the two LEDs flash alternately (PAN. 8). Make contact with
the supplier.
GENERAL RECOMMENDATIONS
Do not let the battery run down completely (maximum 80%): it will last longer.
Keep the battery contacts free of oxidation. Keep the charging area well
ventilated.
MAINTENANCE
Keep the fan and the ventilation holes clean. To clean the outside, use a
damp cloth. Use only original spare parts.
