132 System Manual SCK Gas Sampling System 42/23-81 EN Rev. 4
Step Procedure
4
Insert the gas sampling probe into the kiln using the touchscreen.
Path: Operation ► Probe ► Probe Action ► Insert
Observe the following:

horizontal and vertical alignment of the gas sampling probe in
relation to the opening in the mounting flange
 stability of the probe retractor fastening elements
 unobstructed mobility of all cable and hose connections
 even movement of the probe carriage
5
Wait for cooling water to heat up: After inserting the probe, the gas
sampling system has a warm-up time to reach the necessary oper-
ating temperature. The
Measured Value on Hold signal is only reset
once the cooling temperature reaches a minimum temperature of
50 °C. Once this signal is active, make sure that no sample gas is
sucked in by the gas sampling probe.
6
Switch the gas sampling probe to automatic mode using the
touchscreen.
Path: Operation ► Automatic on / off
Result: The sampling system is thus in automatic mode and monitors itself.
After switching on the gas sampling system there may be differences in probe
retractor travel speed depending on the capacity of the compressed-air supply
provided by the customer. The travel time for one insertion/retraction of the gas
sampling probe must be approx. 20 seconds. You can adjust travel speed as fol-
lows:
Step Procedure
1
Turn service switch to ON position.
WARNING! The probe moves out of the kiln. Do not stand in the
area of travel of the probe or probe carriage.
2
Adjust travel speed to the desired setting using the ball valve on the
compressed-air motor.
3
Turn service switch back to OFF position and insert probe again
using the controller.
WARNING! Probe moves into the kiln. Do not stand in the area of
travel of the probe or probe carriage until the probe is com-
pletely inserted into the kiln and the warning lamps go out.
