3.6.2 Warning Symbols

In case of a battery, filter, or blower warning at the start of the SVE, the SVE will turn off itself automatically after
20 seconds or by pressing the operating button.
Every warning during operation has to be confirmed by pushing the operation button shortly. There might be
another display of error after 20 seconds!
a) Battery warning
The error message is displayed when the battery is almost completely empts or a commu-
nication problem between SVE and battery controller occurred.
If falling below the remaining operating time of 15 minutes, this error message is displayed.
- In case of battery warning:
- A permanent acoustic signal sounds.
- The battery-warning symbol blinks on the display.
The batter-warning symbol blinks permanently, also the permanent acoustic signal sounds
discontinuously, until only about 3% are left to the complete discharging of the battery.
Afterwards, the SVE turns off automatically.
Action: Immediately stop working, leave the area, and exchange/charge the SVE/battery.
b) Filter warning
A filter warning occurs when there is no filter in the respiratory mask or the filter is too dirty and
the minimum airflow cannot be reached.
Also, a filter warning occurs when a filter is too dirty during operation.
The filter warnings are displayed for the respective filter (SVE in full-face mask mode does not
gives a warning).
