Maintenance intervals
The measuring system must undergo maintenance at certain intervals in order to
guarantee proper functioning. The recommended maintenance work is presented in the
table below. The maintenance intervals specified there are based on the extensive
experience of Siemens AG. The maintenance intervals can be further optimized if local
conditions and empirical values suggest this. It is up to the system owner to decide
whether to shorten or extend the maintenance interval on a system-related basis.
However, extending the maintenance intervals requires official approval. Depending on
the composition of the sample gas, it may be necessary to shorten the maintenance
intervals.
All maintenance work that is marked with 'S' in the following table may only be carried
out by adequately trained personnel authorized by Siemens. Siemens offers six-monthly
maintenance services as an optional service.
All maintenance work marked with 'C' can be performed by trained or appropriately
instructed personnel of the customer.
