A group fault message is output on the operator display if one or more of the following
conditions is not met:
• All fuses are OK
• All gas preparation elements are OK
• The maximum permissible cabinet temperature has not been reached or exceeded
• The minimum temperature of the sampling probe has been reached
• The minimum temperature of the sample gas line has been reached
• All air conditioning units (options) are OK
• Analyzer 1 is OK
• Analyzer 2 (option) is OK
• Analyzer 3 (option) is OK
• Flow rate is in the permissible range (72 ... 120 l/h) for each analyzer
The group fault message remains active until all individual fault messages are

The group fault message is also output when the system is switched on. It is normally
reset automatically after the warm-up period ends.
