aspects for the protection of people and for safe, fault-free
operation. Further task-related safety notices appear in the
sections on transportation, installation, checks before initial
operation and maintenance.
2.1 Intended use
The Model 140 converter is a precision electronic pressure
regulator which provides an output pressure that is
proportional to a given control signal. It is intended for
pneumatic applications where fine control of air pressure or
regular automated pressure changes are required.
Misuse

Dangerous if misused!
• Incorrect use of proportional control valves
can create dangerous situations.
• In areas where an explosive atmosphere may
be present, only use Hazardous Area Certified
equipment
2.2 General dangers
The following section lists residual risks which may be
present even if the safety valves are correctly used.
Compressed air
WARNING!
Danger of injury caused by compressed air!
Compressed air can cause injuries if not
