2.4 Safety Equipment/Safety Measures
Hazards from electrical equipment
The LT2 Lambda Transmitter and the Lambda Probe is equipment for use in industrial electri-
cal power installations. Always switch off the power when working on mains connections or
mains voltage. If contact protection has been removed, reattach it before switching on the
power supply again. Damage to health or equipment may result from improper use or improp-
er handling.
NOTICE
To avoid damage, always observe the respective security notices.
Preventive measures for improving operating safety
If the LT2 is used in conjunction with control and steering technology, the operator must ensure
that any breakdown or failure of the LT2 device does not cause inadmissible damage or dan-
gerous operating states. To avoid faults which could cause direct or indirect personal or ma-
terial damage, the operator must ensure that:
• the responsible maintenance personnel can be reached at any time and as quickly as pos-
sible
• the maintenance personnel are trained to correctly respond to faults with the LT2 Lambda
Transmitter and the associated malfunctions
• in the case of doubt, the faulty equipment can be switched off immediately
• A switch-off does not lead to direct follow-up problems.
Avoiding consequential damages
To avoid consequential damages in the event of failure, which could cause direct or indirect
personal or material damage, the owner must ensure that qualified personnel can assess the
faults and initiate appropriate measures to tackle them.
2.5 Protection Against Emissions from Gas Carrying Channels
The Lambda Transmitter LT2 is attached directly to the gas-carrying duct by the probe instal-
lation fitting (PIF) and the mating flange. If the LS2Lambda Probe or the probe installation fit-
ting (PIF) is removed, the operating system, especially if pressurised, can cause corrosive
and/or hot gas to escape from the duct through the flange, causing severe injury to the oper-
ator if the operator is unprotected and if appropriate safety precautions have not first been tak-
en.
WARNING!
Discharge of hot, corrosive gases!
With pressurised gas, corrosive gases and/or temperatures higher than 200 °C in the gas-car-
rying duct, gases can escape if the Lambda Probe LS2 or the probe installation fitting (PIF) is
removed
 Before opening, switch off the installation. If this is not possible, put on protective clothing
and masks
 Place appropriate warning signs in the vicinity of the unit
 Reseal the opening immediately. Appropriate sealing flanges (blind flanges) are available
as accessories
