recommended that this be done as required but at least once a
year)).
4.
Replace seals in contact with medium (at least once a year, no
further recommendations are possible as this depends to a large
extent on the process, material and usage frequency of the
assembly).
5.
Once maintenance work has been completed, perform the
following final inspection:
• Assembly moves to measure and service position?
• Service and measure feedback signals present?
• Process connection and compressed air connections sealed?
• Does measurement indicate plausible values?
The replacement of sealing elements depends on the assembly type. The replacement
instructions are included in the relevant service kit. The required service kit can be found
in the Operating Instructions for your assembly.
