2.0 INSTALLATION
This section provides information pertaining to installation of a Series 150N Valve Positioner.
This entire section should be reviewed before proceeding with the installation.
Positioner installation is dependent upon the type of valve actuator and its characteristics, and the
effect of the valve on the process. Obtain this information before proceeding with the installation.
Operating temperature limits are stated in the Specifications section of this Instruction. The tempera-
ture in the selected location must not exceed the specified operating temperatures.
CAUTION
Exceeding the specified operating temperature limits can
adversely affect performance and may cause damage to the
Positioner.
The Positioner will need to be calibrated before being put into service.
2.1 SHIPPING AND STORAGE
If the Positioner is to be stocked, stored, or shipped to another location prior to piping, make sure that
the factory installed plastic plugs are in the pneumatic ports to prevent entry of moisture, dirt, or other
contaminant.
2.2 MECHANICAL INSTALLATION
Refer to Page 1 for dimensions and mounting hole locations.
Rigidly mount Positioner to actuator to prevent relative motion. The Positioner may be mounted in any
orientation. Feedback torque is 7 inch/lbs. maximum. The location must provide access for:
• Mechanical interconnecting of Positioner and actuator
• Routing of pneumatic piping
• Removing of access cover
• Servicing
Note that the extension spring and related parts mentioned in the following procedures, and shown in
Figure 2-1, are present only when a quick opening cam is used.
