USING THE ON-BOARD CHARGER (BI-ENERGY).

4.7.1. Characteristics.

The drive batteries must be charged using the charger provided. DO NOT OVERCHARGE.
• Charger: 24V - 50A
• Power supply: 220V single phase - 50 Hz protected by a 30 mA differential circuit breaker.
• Service voltage: 24V
• Charging time: about 12 hours for 70-80% discharged batteries
• Charging curve fully regulated by micro-controller
• Protected against battery polarity inversion by 3 output fuses, 25 A automobile type
• Mains supply: standardized socket: 2 pole + earth 16A - 230V

4.7.2. Starting to charge.

Start-up is automatic when connection to the mains is made. The charger is fitted with two indicator lights
• the green light indicates mains supply
• the yellow light indicates charging is in progress:
− it comes on when charging starts
− it flashes quickly once the charger output voltage threshold value reaches 29 V
− it flashes slowly if overcharging occurs
− it flashes during the equalising phase
− it goes off when charging is over, or if the mains supply is cut.
• If a fault occurs during charging, the green light flashes

4.7.3. Top-up charging.

If the charger remains connected to the main for over 48 hours, it starts a new charging cycle every 48 hours
after the previous charging finished, to compensate for self-discharging.

4.7.4. Charging interruption.

The charger is stopped by disconnecting the mains supply. If it is necessary to manoeuvre the machine
during a charging cycle, the charger must be unplugged. After the manoeuvre, reconnect the charger. If
charging was interrupted for over 13 minutes, a full charging cycle is started.

4.7.5. Precautions for use.

Avoid recharging the batteries if the electrolyte temperature is over 40°C. Let it cool down.
Keep the tops of the batteries clean and dry: a faulty connection or corrosion can cause a considerable loss
of power.
If new batteries are installed, recharge after 3 or 4 hours' service. Do this three to five times.
The charger was factory-set with the cable fitted to it. If a replacement cable is fitted, be sure it is of the same
cross-section and length.
The charger is protected by a time-delayed fuse 2 50V 15A 6,3 x 32 fitted directly on the electronic card. In
the event of a fault (charger not working), do not attempt to repair it. Contact PINGUELY-HAULOTTE After-
Sales Department.

BATTERY USE AND MAINTENANCE.

The batteries provide the power for your platform. Here is some advice to obtain optimal performance from
them, without risking premature deterioration.
WARNING.
Do not use the machine while charging.
