O
2
value display:
If the O
2
control has been switched off, the
O
2
display does not show an actual value (-
- -).
This procedure provides protection for the
O
2
sensor.
If the set value is set to 21%, the O
2
control
loop is not monitored. This applies to both
O
2
control ranges:
• Control range I: 1% to 21%
• Control range II: 5% to 90%
In this case, the O
2
display shows the
actual value.
Airing the work space:
If the device was operated with O
2
or N
2
,
the work space must be aired after the O
2
control has been switched off.
