Battery-backed operation (optional)

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.
Treating a patient in battery mode is permissible.
WARNING
Danger of touching live parts
If the covers are open on the unit, there is a possibility of touching live
parts inside the unit.
➢ When using the unit on the patient, please ensure that the covers
on the rear side of the unit (service cover, USB cover) are closed.
NOTE
Observe operating state LED
Observe the operating state LED (see "Operating state LED [→ 29]").
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 in the Windows task bar displayed at the bottom of the
screen.
This beeps 20 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 20 seconds have elapsed, the operating system is shut
down.
NOTE
Information on back-up cycles
The storage battery is designed for fully cable-free use of Scan,
Design and Grinding at a power requirement of 250 W for 60 minutes.
Approx. 2.5 hours are needed for full charging.
For back-up mode, which the user, for example, uses for an operation
lasting 10 minutes, in order to move the unit from door to door
(standby consumption of 100 W ), a charging time of 10 minutes is
needed. After around 1000 buffer cycles the capacity of the battery
fades due to the nature of the battery technology used.
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.
