ProKiln GAC400 PROBE GAS SAMPLING SYSTEM | OI/GAC400-EN REV. A
Instructions: checking probe position and retractor movement
How to check probe position:
1. Operation/Service Mode -50S15 switch must be in the
Service Mode
2. Switch system to manual mode on the HMI (if this has not
already been done).
Path: Home ► Manual
3. Retract gas sampling probe out of the kiln.
Path: Menu ► Probe Position ► GO S0
WARNING! The probe moves out of the kiln. Do not stand in
the area of travel of the probe or probe buggy until the probe
has reached its end position.
4. With the probe in position S0, check the distance between
the back roller wheel and retractor frame, as indicated by the
red arrow in the illustration below, to be 200 mm.
If the distance is 200 mm, the system can be set into normal
operation. If the distance is not 200 mm, proceed below to
step 5.
5. Push the Encoder Menu button on the Probe Position setup
page and the below menu appears:
6. Push the button Override S0 and S3 for manual operation of
probe. Use the push-buttons Probe In
on the retractor control cabinet to position the probe at the
correct length of 200mm. Use a ruler to check the correct
length.
7. When the probe is positioned at 200mm, push the Encoder
Reset button on the Encoder Menu to provide a new raw
value for the S0.
8. Finalize the reset by confirming the Encoder Reset by
pushing the OK button
9. Push the Go S3 to insert the probe into the measuring
position
10. Switch system to Auto mode on the HMI
Path: Home ► Auto
11. Operation/Service Mode -50S15 must be switched to
Operation Mode
Cooling module: Vent the cooling-water circuit
Make sure that there are no air pockets in the probe water
cooling tubes, which could prevent sufficient cooling of the
probe. Since the water flow given by the pump in the water-
cooling system compared to the cross-section of the probe
cooling jacket is so high, the water will itself vent out any air
pockets outside the probe water cooling tubes, and into the
water tank, which is not pressurized. Therefore, no cooling water
circuit venting is required.
