2.4 Safety Equipment/Safety Measures
Hazards from electrical equipment
The LT3 and the Lambda Transmitter Combination Probe is equipment for use in industrial
electrical 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 LT3 is used in conjunction with control and steering technology, the operator must ensure
that any breakdown or failure of the LT3 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 LT3 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.
Protect against gas leakage from the gas-bearing channel
The Combination Probe KS1Dis fitted directly to the gas-bearing channel via the probe instal-
lation fitting (PIF). If the Combination Probe KS1D or the probe installation fitting (PIF) are dis-
mantled, depending on the plant but particularly in the case of excess pressure, aggressive
and / or hot gas can seep out of the channel and this could pose a serious health hazard to
an unprotected operator if suitable safety measures have not be taken previously. For preven-
tion, suitable protective measures must be taken in advance.
WARNING!
In the case of excess pressure and temperatures in excess of 200 °C in the gas channel, gas-
es could escape when dismantling the Combination ProbeKS1D or the probe installation fit-
ting (PIF).

Always switch off the plant prior to opening. If this is not possible, wear protective clothing
and a mask.

Fix respective warning information in close proximity to the mounting site.

Immediately seal the opening again.
