Page 10: Safety Equipment/Safety Measures
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. - Page 11 NOTICE Do not switch off the Lambda Transmitter LT3 as long as the KS1D Combination Probe is mounted. Not even if the associated plant has been brought to a standstill. Residual gases will cause corrosion and could damage the probe.
