Maintenance and Servicing
5.3.2 Battery management system (BMS)
The battery management system (BMS) ensures the battery is monitored and
secure. The BMS is responsible for:
• Determining the battery charging state during operation
• Switching off the cleaning functions when the discharge limit has been
reached to protect the battery against total discharge
When using other batteries which have been approved by Hako, the BMS
must be reset.
5.3.3 Checking the charging state
During operation, the charging state of the batteries is displayed in the display
panel Fig. 14-51. Different numbers of fields are displayed depending on the
charging state:
• Four fields visible: Battery is fully charged
• Three fields visible: Battery is charged to approx. 2/3
• Two fields visible: Battery is charged to approx. 1/3
• One field visible: Cleaning functions are switched off after 3 minutes
• One field is flashing and a signal is output: Machine can only be further
operated at reduced speed.
Charge the batteries immediately!
Attention
The settings of the BMS should only be carried out by a workshop
authorised by Hako!
