Accumulator function
The accumulator function ensures that cold energy is stored automatically
(up to 8 hours) if enough electrical power is available, for example when
supplied by a mains adapter.
Stored cooling power is discharged
z
automatically when the switch-off voltage is reached (see the table on
page 33)
z
or manually by pressing the discharge button (
1
A2 or
2
4, page 3).
The cold accumulator can only be discharged manually if it was
fully charged beforehand.
The accumulator is automatically charged if,
z
the restart voltage is exceeded
z
or the accumulator is empty and you switch the device off and on
again using the control button (
2
6, page 3, does only function on VD-
06).
5.3
Battery monitor
The cooling unit is equipped with a battery monitor which switches the
compressor off and on again and thereby protects both the battery and
compressor against damage. The switch-off and switch-on points measured
at the connection terminals of the electronic system compressor are listed
in the following chapters.
