Important
The TZIDC, TZIDC-110, TZIDC-120 positioner must be supplied with instrument air that is free
of oil, water and dust.
The purity and oil content should meet the requirements of Class 3 according to
DIN/ISO 8573-1.
Notice - Potential damage to parts!
Impurities on the pipe and positioner can damage components.
The recommended pipe dimension is 6 x 1 mm. Dust, splinters or any other particles must be
blown off the pipe before connecting.
To connect the air pipes, G1/4 or 1/4-18 NPT tap holes are provided. We recommend that you
use a line with the 6 x 1 mm dimensions.
Notice - Potential damage to parts!
Pressure above 6 bar (90 psi) can damage the positioner or actuator.
Provisions should be made to ensure that in the event of an error the pressure does not rise
above 6 bar (90 psi).
