Introduction
The acquisition unit PC has a battery-backed power supply. It is thus
possible to operate the acquisition unit for a short time with no line
voltage connected.
CAUTION
No treatment without connected line voltage
Treating a patient (generating intraoral acquisitions) is not permitted if
the unit is not connected to the power supply of the practice.
The following parameters are constantly checked by the installed
monitoring software in order to monitor the battery back-up function:
● Line voltage present:
● Charge set of storage battery pack
● Fan function
● Temperature of power supply
When the unit is running in the battery-powered mode, this is indicated
by a message displayed at the bottom of the screen. It is accompanied
by a rhythmic beep.
This beep changes to a continuous signal 30 seconds before the
system shuts down due to insufficient battery power. A corresponding
display then appears in the center of the screen. The user thus has time
to finish his last actions on the PC.
As soon as 30 seconds have elapsed, the operating system is shut
down.
NOTE
The operating time of the storage batteries is not constant. It depends
on the charge state, the load and the age of the storage batteries.
NOTE
In battery mode, the CEREC AC Connect acquisition unit must
remain connected to the mains supply for at least two hours after
using the battery buffering to charge the storage batteries.
At least every three months the CEREC AC Connect acquisition unit
must be connected to the mains supply to charge the storage
batteries.
