2.2. Circuit outputs
The central battery unit outputs can be con
nected by the “Mode” connectors (see page 6) in steps of 2
circuits, either as maintained or non-maintained circuits.
2.3. Charging
After a power failure or after installing the unit, the unit charges the batteries with constant current, until
the battery voltage reaches the maintenance voltage level. The charging current can be selected from
the charger module card with a DIP switch. See section 4.1. Setting the charging current.
Network LED is lit, when the battery is charging
Charging LED is blinking, when the battery voltage has not reached the maintenance voltage
The charging LED is lit when the battery voltage has reached maintenance voltage.
2.4. Main voltage limits
When the main voltage drops below 180 V, the unit changes to battery use.
Battery use LED is lit
When the network returns or gets higher than 195 V, the unit changes again to mains use, and starts
to charge the batteries.
Main use LED is lit
Charging LED is blinking or lit
2.5. Battery voltage limits
If the battery voltage rises over 260 V in normal mode, an over-voltage alarm is given.
Main use LED is lit
Over-voltage LED is lit
Battery fault LED is lit
Internal fault LED is lit
If the battery voltage drops under 228 V in normal mode, an under-voltage alarm is given.
Main use LED is lit
Under-voltage LED is lit
Battery fault LED is lit
Internal fault LED is lit
When the unit is in battery mode, and the voltage drops below 195 V, a deep discharge alarm is given.
Deep discharge LED is blinking
Internal fault LED is lit
When the unit is in battery mode, and the battery voltage falls below 173 V, the unit goes into deep
discharge protection mode, where the battery discharge is stopped.
Battery use LED is lit
Deep discharge LED is lit
Internal fault LED is lit
Deep discharge LED stays lit until it is reset from the
reset/test
button. Resetting is possible only after
the mains supply has returned.
The unit can be switched to emergency mode also remotely, if this feature is used.
Main use LED is blinking
Battery use LED is lit
