Installing the analyzer modules and option module
5.3 Installation of the analyzer modules
Connecting
1. Connect the option module OM 2.1 to the analog current interface of the analyzer module
2. Connect the processing unit (PU) to the CAN interface on the AM-PCB
3. Make sure that power is provided to the AM-PCB from the power supply unit
4. Install the housing cover.
Note
Tightening the cap nuts
Tighten the cap nuts with a torque of
• 2.5 Nm.
5. Connect the gas connections, see Gas connections (Page 44).
6. Check the sample gas path for leaks, see Checking the sample gas path for leaks
Note
Reference gas line
Make sure that the reference gas line has the following characteristics at measuring
spans of < 2% oxygen: The smallest possible cross-section (e.g. pipe diameter 2 mm) of
metallic material (e.g. stainless steel).
