TYPE AV1 PNEUMATIC POSITION TRANSMITTER
INSTALLATION
D - 2
INSTALLATION
NOTE: This option is only available for Type AV1__0___
positioners.
Installation is similar to normal positioner installation (Section 3).
The actuator should be coupled to the position transmitter cam
shaft so as to cause a 90-degree rotation of the shaft for full travel
of the device (or 45-degree for Type AV1_1____ positioners). For
a linear motion device (i.e., diaphragm actuators), the cam shaft is
driven by the drive arm and the connecting link as the positioner
application. For a 90-degree rotation device, it may be desired to
couple the cam shaft directly to the actuator. The zero position of
the cam shaft can be adjusted in 45-degree increments by reposi-
tioning the cam on the shaft.
The direction of the transmitted signal can be reversed by placing
the reverse acting cam, located on the inside of the positioner
cover, on the cam shaft.
