The following instructions are designed to assist in
unpacking, installing and performing maintenance as
required on Logix™ 500 Digital Positioners. Series 500
is the term used for all the positioners within the family;
however, specific numbers indicate features specific to
a model: Logix 520 indicates that the positioner uses

sonnel should thoroughly review this bulletin prior to
installing, operating, or performing any maintenance on
the valve.
Separate Valtek Flow Control Products Installation,

sories. Refer to the appropriate instructions when this

To avoid possible injury to personnel or damage
to valve parts, users must strictly adhere to
WARNING and CAUTION notes. Modifying this
product, substituting non-factory or inferior
parts, or using maintenance procedures other
than outlined could drastically affect perfor-
mance and be hazardous to personnel and equip-
ment, and may void existing warranties.

Unpacking
1. While unpacking the Logix 500 positioner, check
the packing list against the materials received. Lists
describing the system and accessories are included
in each shipping container.
WARNING: When lifting a valve/actuator
assembly with lifting straps, be aware the
center of gravity may be above the lifting
point. Therefore, support must be given to
prevent the valve/actuator from rotating.
Failure to do so can cause serious injury to
personnel or damage to nearby equipment.

per immediately.
3. Should any problem arise, contact a Flowserve
