Battery Service Hub PSW User Manual
INSTRUCTIONS FOR POWER-SWITCH BATTERY CHARGES (PSW)
The battery charges 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 cor-
rect 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 a 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 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 ven-
tilation holes. Any overheating of the PSW will reduce the output current; if overheating continues, charging will be stopped (see SPECIAL
SIGNALS).
FIXED INSTALLATIONS: 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
(FIF. 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 a 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 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 1V/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 batter-
ies, 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 pro-
