lation and calibration. Detailed installation and calibration

information is contained in Section 3 and Section 4 respec-

tively.

INTENDED USER

The information in this instruction is a guide for technical person-

and repair of the positioner.

DESCRIPTION

The Type AV1 and Type AV2 positioners are control devices that

satisfy a wide range of applications. They provide fast, sensitive

and accurate positioning of pneumatic single or double acting

actuators.

The Type AV1 positioner receives an external pneumatic signal

and converts it to a pneumatic output. The Type AV2 positioner

accepts a four to 20-milliamp current that is applied to an I/P (cur-

rent to pneumatic) converter, located inside the housing, to gener-

ate an internal signal pressure.

If a loss of signal occurs, the Type AV2 positioner goes to the

four-milliamp position. The Type AV1 positioner goes to the 3 psi

position.
