138 System Manual SCK Gas Sampling System 42/23-81 EN Rev. 4
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 (Errors on page 213).
Check general condition of the system (Checking general condi-
tion on page 140).
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).
If the gas sampling probe was installed in accordance with the recommendations in
the Installation section and in the project planning documents, adequate protection
of the probe is guaranteed in operation.
The probe (probe pipe and filter) may nevertheless get damaged, above all in the
following situations:
if material falls on the probe
of too much material adheres to the probe pipe
