6.4.2 Battery Condition Monitoring
The Battery Charger in the OmniCare EVC System system not
only charges the batteries, but also monitors the condition of
them to detect battery degradation.
• If the charger runs continuously for more than 24 hours (i.e.
batteries have not reached 27.6 V DC within 24 hours), then
the “Charger Fault” LED will be illuminated.
• If the battery voltage falls to 24.0V DC within 6 minutes of
the charger finishing (i.e. battery voltage drops from 27.6V
DC to 24.0V DC) then the “Charger Fault” LED will be
illuminated.
• The Battery High LED illuminates at 28VDC.
• The Battery Low LED illuminates at 20VDC.
• If the Battery HIGH and Battery LOW LEDs are both
illuminated then the Batteries are disconnected.
Battery disconnect occurs at 20VDC, (if running on batteries).
NOTE: Serviceable batteries should reach 27.6V DC within 24 hours.
NOTE: Serviceable batteries should hold charge for longer than 6
minutes.
NOTE: If Batteries are reconnected while Mains is still connected and
their voltage is less than 20V DC the charger will not restart.
