-EN Rev. E Operating instruction SCK Gas Sampling System 131
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 connec-
tions

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 neces-
sary operating temperature. The Measured Value on Hold sig-
nal is only reset once the cooling temperature reaches a mini-
mum 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 follows:
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
completely inserted into the kiln and the warning lamps go
out.
