Replacing the measuring probe
1
Disconnect the probe cable in the connection unit.
2
Loosen the counterflange bolts and remove the probe.
3
Install the new probe with a new seal. Determine the flow direction of the flue gas and
align the V shield (
see “Aligning the V-shield”, page 29
).
4
Fasten the counterflange bolts and connect the probe cable in the connection unit.
5
Switch on the supply voltage and wait until the probe has reached the setpoint
temperature.
6
Perform a 2-point adjustment under process conditions.
WARNING: Risk of burns
The temperature of the probe filter head and all parts in the process gas is 150 °C to
800 °C (302 °F to 1472 °F) during operation. Directly touching the parts for
disassembly or maintenance causes serious burns!
▸
Use heat protection gloves when removing the probe.
▸
Switch the electronics supply voltage off before removing the probe.
▸
Place the probe in a safe, protected area after removal and wait until the probe
temperature has cooled down to the ambient temperature.
