Switching the O
2
control on and off
1. To toggle between two states of the O
2
control:
• Press the + key.
or
• Press the - key.
2. The value change appears in the display. The New message indicates that the selection has been
changed, but not saved yet.
3. To accept and save the setting:
• Press the
Enter
key.
• The system returns to the
Options
menu.
Airing the workspace
If the unit is operated with an O
2
or N
2
supply, the workspace must be vented after de-activating
O
2
-control.
Gas monitoring
The switching state of the O
2
control loop does not affect the function of the optional gas monitoring
system. The gas monitoring system remains active even when the O
2
control is switched off or the
O
2
-sensor is disabled.
Note
Display of O
2
value:
When O
2
control is de-activated, the actual value readout shows three dashes (- - -) in the O
2
display field.
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 is true for both O
2
control ranges:
• Control range I: 1 % - 21 %
• Control range II: 5 % - 90 %
In this case, the O
2
display shows the actual value.
