I) WOWa-CHARGING SYSTEM
Fast charging method conforming to DIN 41772.
• Compared to the Wa method, this method allows shorter charging times, since battery is charged with a
higher current during the first stage. This system has turned out to be very useful especially when batteries
are subject to fixed working and charging times.
• The max. charging time with a 80% discharged battery is 8 hours; therefore this system is welcome by
all battery manufacturers.
• The charging process consists of two stages during which a fixed current is delivered, depending on the
construction system of the transformer. Each stage is controlled by a terminal board which controls the
charging current of the relevant stage autonomously in order to make the charger suitable for any working
condition.
• The AP735WW card is preset for the WOWa function since it is equipped with an additional relay
switching the contactors.
• All other functions of the controller are unchanged compared to a conventional charger.
J) SAFETY DEVICES
• Fuses on mains input.
• An output fuse as protection against polarity reversals and/or overloads.
• The electronic control card is equipped with a safety timer which stops the charging process after 7 hours
on WOWa chargers or 11 hours on Wa chargers, if battery charger has not switched to final charge. This
is signalled by the red "FAULT" LED lighting up. In that case both charger and battery have to be checked.
• Automatic switching off of charger on battery disconnection during the charging process.
• If a power failure takes place, the red LED blinks signalling a FAULT. Zero current (0A) and the AC symbol
(~) are displayed. Since all charging data are stored, on power-fail restart the charging process is
automatically resumed from the point reached before stopping.
PROPORTIONAL CHARGE: It is a system devised to prevent damages due to prolonged charging of batteries
already partially charged. Should battery voltage reach 2.4 V/cell within the first hour of charging, a final
charge will take place, lasting half the time of the initial charge.
When the final charge is over, the card signals "END OF CHARGING" (green LED).
The proportional charge can be enabled or disabled by means of the JP7 jumper (CP) on the
AP735USA card.
K) DISPLAY SYMBOLS
Four-digit LC display with 12 multifunctional symbols displaying the charging data recalled by pushing the ON-
OFF button as follows :
• Current delivered in real time (A)
• Instantaneous voltage at battery terminals (V)
• Voltage before the charging process, measured while performing the Autostart function (V)
• Current at the beginning of the charging process (A)
• Delivered ampere-hours (Ah)
• Overall charging time (hours : minutes)
• Battery voltage at the end of the charging process (V)
• Current at the end of the charging process (A)
