PSW Battery Chargers—User Guide (page 2 of 4)

gramming 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.

SPECAIL SIGNALS

When the microprocessor detects a problem, it stops charging and signals this by flashing the two LEDs (PAN. 4).

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 battery on a 24V charger).

In order to determine the king 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. 8), 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. 5); 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. 6).

To interrupt the charge in the PSW is fitted on board, disconnect the mains supply and use the vehicle. Never disconnect the battery if the

charge 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 on

the battery condition. During charging pulses the display indicates STOP (PAN. 3).

If charging is interrupted by the pushbutton (PAN. 6), 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 (MUTLIPROGRAMMER) connected to the programming connector shown in Fig. 2.

Contact the supplier for purchase of a MUTLIPROGRAMMER-CLIENT.

Reading this information helps detect the problems and their cause.

It will be easily understood whether they are caused be a malfunction of the charger of the battery. It is also possibly 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 hand-

books.

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.
