7.2.1 Function test
You need the following documents for this:
• Circuit diagram
• Gas flow diagram
• Operating instructions for all analyzers
By switching on the supply voltage, you are putting the system into ready state. Then:
• Assign the analyzer parameters according to their function.
• Check or simulate the heating control loops.
• Check all status messages of the analyzers and the system (e.g. moisture monitoring,
cooler, temperature monitoring of sample gas line, flow monitoring, reference gas
monitoring, switch operation, etc.).
• Check the analog signals of the analyzers (4 - 20 mA).
• Check the pumps and solenoid valves for proper functioning.
• Simulate the status messages of the system at the S7 inputs and check the
respective reaction, e.g. pump shutdown on condensate penetration, flow monitoring,
switch operation, heater fault messages, cooler status messages, analyzer status
messages, valve enables, automatic calibration cycle, maintenance messages and
fault messages to the control center, etc.
• Introduce the calibration gases and perform a manual calibration or autocalibration.
