Fault: Low Battery Capacity.
Description: Low Battery Capacity detected at startup.
What to do:
1.
Allow the batteries to charge during 6 hours.
2.
Check / replace internal batteries.
Fault: Internal batteries not possible to charge fully.
Description: The 24 V-voltage does not increases after 1 hour charge or is

What to do: Replace internal batteries.
Fault: Failure on the +24 voltage.
Description: The supervision of the +24 voltage indicates an error. Alarm 510 is
generated.
What to do:
Check if +24V_PTC is available at P59 on PC 1675 Power Supply:
• If +24V_PTC is not available, replace the AC/DC Converter.
Note: As the two fans inside the battery drawer runs on +24 V, this error is easy to
identify by checking the function of these fans.
• If +24V_PTC is available, this voltage is correctly generated by the Power Supply
system. The error must be found on PC 1672 Control Panel or in the
cables/connectors.
