Installation, Operation, and Maintenance Manual
ES-09373-1
Pneumatic Connections
Instrument air must be of better quality than industrial compressed air. Humidity,
suspended particles, and oil can impair the instrument's operation temporarily or
permanently if internal parts wear out.
Impurities in the supply air can partially or completely damage the positioner's
internal components. Before connecting the conduit, it is essential to remove dust,
oil, or other impurities.
IMPORTANT
Before instrumentation air is connected to the positioner, we recommend that the
hose be opened freely for 2 to 3 minutes to allow any contamination to escape.
A pressure exceeding 10 bar (145 psi) may permanently damage the positioner.
Measures must be taken to ensure that even if the compressed air supply fails, the
pressure does not exceed 10 bar (145 psi).
