Checking/correcting operating
parameters
Modifying the controller operating parameters
The probe gas sampling system control system has factory
settings that can be modified to specific system conditions at
start-up. It is possible to edit alarm limits within a pre-
established range in order to provide for specific system
conditions.
Limited configuration serves to protect the probe retractor
against harmful or contradictory settings.
A list of operating parameters can be found in Default operating
parameter settings, see Default operation parameter settings
on page 30. It is possible to display the operating parameters on
the control cabinet HMI by scrolling though the relevant menu
pages on the HMI.

Inserting the probe and switching to
automatic mode
Requirements
The following conditions must be met:
Turn the Safety switch to "Off" position, the gas sampling probe
is retracted from the kiln (see Operating the service switch on
page 100).
Instructions
Proceed as follows:
1. Check that the water flow in the water-cooling system is
correct (see Default operation parameter settings on
page 30).
The rotor of the water pump must run according to arrow
indication on unit. If necessary, adjust the direction of
rotation by changing the power phase position.
2. Make sure the safety switch is in "OFF" position in order for
lock the probe in its position.
3. Make sure that no mechanical locking bar (see Requirements
on page 59, Pos. 1 ) is attached to the flange shutter, and it
is able to open.
4. Leave danger area around the retractor, close protective
installation and turn service switch to "ON" position.
5. Turn the system into manual on the HMI.
6. Open the flange shutter from the HMI for visual inspection
while standing outside the protective installation area.
7. Check the kiln wall tube for clogging and clean if necessary.
Note: Inserting the gas sampling probe when the duct
opening is clogged can lead to damage to the probe and is
therefore not permitted.
If cleaning is necessary, go back to step 2 in this procedure.
If cleaning is necessary, only trained people in heat protective
equipment must perform this task.
8. Insert the probe for the first time into the kiln in manual
operation mode in steps of 0,5 m every 5 minutes using the
push buttons in "Probe Position Setup" until full penetration
depth is reached (position S3). Low motor speed is achieved
by using the "In Low" button, while normal motor speed is
achieved by using the "Probe In" button.
