The positioner saves the new settings, automatically returns to the operating level and
continues operation in the same mode that was active before the configuration level has
been selected.
3.5 Functional test / maintenance
The TZIDC positioner is virtually maintenance free.
To ensure error-free and maintenance-free operation always supply the positioner with
instrument air exempt from oil, water and dust according to DIN/ISO 8573-1 (purity and
oil content acc. to Class 3, pressure dew point 10 K below the operating temperature).
We recommend to check the integrated air filter on a regular basis and replace it if
required.
If the optionally installed filter regulator is installed, it has to be checked regularly as well.
Additionally, the control position should be checked periodically for conformity with the
tolerance limit.
!
WARNING
Do not make any changes to devices with explosion protection.
IMPORTANT
If you should modify or manipulate the electronics of a positioner without
explosion protection, the positioner's warranty will expire immediately.
