8.2.2 Charging the battery
NOTE!
The expected duration for charging the battery depends on the ambient
temperature and the state of charge of the power supply battery.
■
If the battery is fully discharged and the ambient temperature is 20 °C,
the expected charging period is approx. 8 to 9 hours until the full capaci-
ty has been reached.
■
If the battery is fully discharged and the ambient temperature is 20 °C,
the expected charging period is approx. 1 hour until the minimum capaci-
ty has been reached.
1. Switch off the lifting magnet.
2. Connect the power supply cable to the supply socket on the front cover of the battery-powered lifting magnet,
then connect to the 230 V AC power supply.
3. After switching on, the indicator light for recharging on the display panel starts flashing and the LED bar display
lights up.
NOTE!
If battery charging does not start, see section 9 “Troubleshooting”.
4. Battery charging is indicated by the flashing LEDs of the bar display in the display panel of the lifting magnet.
The current state of charge can be displayed by briefly pressing one of the control buttons on the panel of the
lifting magnet.
5. The end of the charging process (maximum state of charge) is indicated by all LEDs in the bar display lighting
up. The installed charger goes to stand-by mode.
