4.1.4 CO-Overload Protection

The CO sensor is protected against overload by the system.

If the limit of 4000 ppm at the CO sensor is exceeded, the internal additional fresh air purging
pump is switched on, which supplies fresh air to the CO sensor.

When the CO overload protection is active, the CO indicator flashes in the status bar of the
measurement screen, and the <Info> status LED changes from "green" to "red".

WARNING

If the opening for the supply of fresh air to the CO sensor is closed, the
sensor can not be purged with fresh air and will be damaged or destroyed
during overload.

Do not lock fresh air opening for fresh air pump!

Fresh air opening

If the CO sensor has been purged sufficiently with fresh air (X disappears behind CO) and
the measured values are within the permissible range, the fresh air flushing pump is switched
off.

The CO indicator in the status bar of the measurement screen no longer flashes and the
status LED <Info> changes from "red" to "green".

Hint

The "CO automatic" option can be used to set how the fresh air flushing pump is
switched off after sufficient purging of the CO sensor:

- automatically

- must be triggered manually

To deactivate the CO automatic option, deactivate the

corresponding option in the menu Adjustments \ Internal \ CO-
Automatic with "No".

To switch off the fresh air flushing pump with the CO automatic

deactivated, press the <F3 <key.
