2 Basic safety information
2.6 Hazards caused by electrical energy
The LT1 LAMBDA TRANSMITTER and the LS1 LAMBDA PROBE are highquality electronic measuring systems. Therefore prudent behaviour is
required when carrying out any measures, decommissioning, transportation
and storage.
2.6
Hazards caused by electrical energy
DANGER!
The parts of the LT1 system are equipment for use in industrial power
systems. When working on mains connections or live parts carrying mains
voltage, mains feeders are to be disconnected from the mains. If shock
protection has been removed, it is to be restored before the voltage is
reconnected. The relevant safety regulations must always be heeded.
2.7
Special hazard areas
The LS1 LAMBDA PROBE is mounted directly onto the gas-carrying duct
using the probe fitting (SEA) and the mating flange. Depending on the
configuration, aggressive and/or hot gas can escape from the duct via the
flange when dismantling the LS1 LAMBDA PROBE and the probe fitting
(SEA), especially in the event of overpressure. This gas can cause serious
injury to the user if he/she is not wearing any protection.
WARNING!
If overpressure and aggressive gases and/or temperatures above 200 °C
occur in the gas duct, gases will emerge when the LS1 LAMBDA PROBE or
the probe fitting (SEA) is dismantled. Therefore the following instructions
are to be heeded:
2.8
•
Switch off the installation before opening. If this is not possible, put on
protective clothing and a protective mask.
•
Put up corresponding warning information near to the mounting
location.
•
Close the opening again immediately. Corresponding cover flange
plates (blank flange) are available as accessories.
Structural modifications to the devices

•
Store the devices in the open air where they are dry and protected!
•
Protect cable ends and connectors against corrosion and
contamination. Corroded connectors can cause functional defects.

5.6 Practical information
Practical information
5.6.1 Damping for jumping
display values
If values are found to be jumping, the display can be damped. Damping is
specified via:
•
Parameter 360 for O2 measurement value (release level for operation)
•
Parameter 441 for pressure measurement (release level for customer)
INFORMATION:
•
A high level of damping will slow down the measurement signal.
•
Measurement values can fluctuate as a result of condensate forming in
the MEV.
Vol. % O2
Drops of water form on the capillary tube. If a drop of water is sucked into
the probe, it will evaporate. If this happens, the display will drop to 0% by
volume O2.. If conditions remain constant (measuring gas temperature), this
event will occur at fairly constant intervals.
Measurement in damp and
heavily contaminated exhaust
gas
•
Observe heating-up time:
− for gas and fuel oil EL
− for coal and fuel oil S
− when incinerating refuse
1 hour
2 hours
3 hours
Never operate the pump when cold!
•
Keep the whole length of the measuring gas sampling tube (capillary
tube) above the relevant dew point for water/acid. Minimum
temperature: 180 °C.
The following should be noted:
− If the measuring gas temperature is lower, the MEV must be
heated up.
− If the measuring gas temperature cannot be maintained along the
whole length of the MEV protective tube, MEV protective tubes with
a core made of an effective heat-conducting material (eg
aluminium/copper) are to be used.

5.6.3 Measurement value
deviations due to
changes in pressure
8
The measurement value is controlled by pressure. The error influence is 1.3
% of the measurement value for each 10 mbar by which the pressure
changes.
Example:
Meas. value =
Error =
21% by volume
0.3% by volume with an increase in pressure
of 10 mbar
The measurement value can be corrected by means of pressure
compensation. Pressure compensation is available as an option. It is
included as standard with the automatic calibration unit.

7.3.1
Information on the faults
(1) If the measurement system works properly again after the fault has been acknowledged and the defect
continues to occur at sporadic intervals, the cause of the fault is the microswitch (contact resistance in the
contact area). If this is the case, the measuring gas pump is to be replaced.
(2) With CO peaks of > 10,000 ppm, the ZrO2 measuring element will produce a voltage (emf) which may
cause the open-circuit monitoring system to respond.
(3) Installation instructions and connection diagrams are supplied with the spares.

7.4 Troubleshooting
If the warning “Sintered metall preliminary filter dirty“ appears:
1.
Check quantity of calibrating gas (section 7.4.4)
Recommended setting:
• Flowmeter
300 to 500 Nl/h
• Restrictor
1 to 5 mbar
2.
Reduce the quantity of calibrating gas gradually
3.
Reset warning
If it appears again, reduce the quantity of calibrating gas again.
4.
If the quantity of calibrating gas goes below 100 Nl/h:
• the SEA must be removed and
• the preliminary filter must be cleaned or replaced.
Spare: Filter element for SEA, order no. 6 55 R 0212.
NOTE:
•
The absolute pressure can be read off before and during calibration.
•
The increase in pressure from the last calibration can be displayed for
comparison by means of parameter 50.
