Monitoring automatic mode
After starting up the gas sampling system you can switch the gas sampling
system to automatic mode. Automatic mode allows continuous operation of
the system for sample gas sampling. Probe cleaning steps take place after
defined intervals (these can be set using the controller).
Observe all safety instructions in the section Safety regulations for operation
on page 136 when performing this work.
The following conditions must be met for automatic mode:
 Gas sampling probe correctly installed and put into operation.
 The gas sampling probe is inserted into the kiln.
How to monitor the gas sampling system in automatic mode:
Step Procedure
1
In controller: switch gas sampling probe to automatic mode (if
this has not already been done).
Path: Operation ► Automatic on / off
2
In controller: monitor operation of the gas sampling system in
the diagnostic screens.
The following parameters are relevant:
 "Cooling Water Pressure"
 "Sample Gas Pressure"
 "Cooling Water Flow Rate"
 "Cooling Water Flow Temp."
 "Cooling Water Return Temp."
 "Probe Heating Temp."
Observe the following rules in automatic mode:
 In case of error signals: read the message on the
touchscreen immediately and take appropriate action ( Er-
rors on page 215).
 Check general condition of the system ( Checking general
condition on page 141).
Failure of mains power leads to immediate retraction of the gas sampling
probe out of the kiln. After switching the power supply back on, the display
and operating unit boots and the sampling system switches to manual mode.
To resume normal measuring operation you must manually insert the gas
sampling probe into the kiln and then switch to automatic mode (see section
Start-up on page 111).
