measuring device via LAMTEC SYSTEM BUS
Connecting diagram see chapter ExternalLink: LAMTEC SYSTEM BUS.
The LAMTEC SYSTEM BUS transmits the following signals to the ETAMATIC:
• probe current
• probe current during calibration
• probe voltage
• cell inner resistance
• heating output
• low pressure
• measured O

value
• operational status and fault status
The LT1/LT2/LT3/LT3-F receives from the ETAMATIC the following signal:
• position of internal firing rate
• status data
• operational modes
