Important
The TZIDC-200, TZIDC-210, TZIDC-220 positioners 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.
Dust, splinters, and any other particles must be blown off the pipe before it is connected.
To connect the air pipes, G1/4 or 1/4-18 NPT tap holes are provided. We recommend that you
use a line with dimensions of 6 x 1 mm.
Notice - Potential damage to parts!
Pressure above 6 bar (90 psi) can damage positioners or actuators.
Provisions should be made to ensure that, in the event of an error, the pressure does not rise
above 6 bar (90 psi).
