(1)
Supply Pressure
Minimum Recommended: 0.3 bar (5 psig) higher
than maximum actuator requirements
Maximum: 10.0 bar (145 psig) or maximum
pressure rating of the actuator, whichever is lower
Medium: Air or natural gas
Air: Supply pressure must be clean, dry air that
meets the requirements of ISA Standard 7.0.01. A
maximum 40 micrometer particle size in the air
system is acceptable. Further filtration down to 5
micrometer particle size is recommended. Lubricant
content is not to exceed 1 ppm weight (w/w) or
volume (v/v) basis. Condensation in the air supply
should be minimized
Natural Gas: Natural gas must be clean, dry,
oil-free, and noncorrosive. H
exceed 20 ppm.

Electromagnetic Compatibility
Meets EN 61326-1 (First Edition)
Immunity—Industrial locations per Table 2 of
the EN 61326-1 standard. Performance is
shown in table 1-3 below.
Emissions—Class A
ISM equipment rating: Group 1, Class A
Lightning and Surge Protection—The degree of
immunity to lightning is specified as Surge immunity
in table 1-3. For additional surge protection
commercially available transient protection devices
can be used.
Vibration Testing Method
Tested per ANSI/ISA-S75.13.01 Section 5.3.5. A
resonant frequency search is performed on all three
axes. The instrument is subjected to the ISA
specified 1/2 hour endurance test at each major
resonance.
