Maintenance

If a limit value is undershot/exceeded, this is indicated in the status line by a down/up arrow 
(see Chapter 

4.3 Status Line

). 

In addition, the following message appears on the display:

Limit value 1:

•

Factory setting: Exceeding of 400 ppm CO

e

, 60 s

Limit value 2:

•

Factory setting: Undershooting of 0.5% O

2

, 30 s

The exceeded/undershoot value starts blinking in the main display 001.

Use the arrow key 

 to change back from display 001 to the appropriate indication of the 

limit values. If the limit value must be quitted by hand a hand symbol is shown in the display. 
Use the ENTER key to quit the limit value.

 
Control of the entry with the following key 
sequence:

, , , .

Limit value off

Monitoring of exceeding

Monitoring of undershooting

Setting of limit value

Setting of trigger time of limit value

NO - limit value resets automatically 
YES - manual acknowledgement of limit value required (see Chapter 

4.4.2
