7.2 CHARGE MODES
The following battery charge modes are available (depending on the equipment):
Floating charge
Floating charge compensates for the self-discharge of the battery and, in normal operation, maintains the battery
in a fully charged condition.
High rate charge (or equalizing charge)
High rate charge restores the battery to full capacity.
Depending on the equipment, it can be activated:
- manually from the keyboard,
- automatically by the system which monitors the state of charge of the battery (mains off or rectifier in current-
limiting mode or on Ah drop),
- periodically by the system at fixed intervals (1 month, 6 months, 1 year: depending on factory setting).
The high rate charge time is factory-set to a value in the range from 0 to 99 hours.
During high rate charge, the remaining charge time can be displayed.
Commissioning charge (or boost charge)
(option)
This mode can be used for initial battery charging and is manually activated from the front display.
Note : High rate and commissioning charges shall be activated depending on the batery manufacturer
recommendations. Refer to battery supplier’s operation manual.
