Flowserve Corporation, Valtek Control Products, Tel. USA 801 489 8611
GENERAL INFORMATION
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
HART
®
protocol. Product users and maintenance per-
sonnel should thoroughly review this bulletin prior to
installing, operating, or performing any maintenance on
the valve.
Separate Valtek Flow Control Products Installation,
Operation, Maintenance instructions cover the valve
(such as IOM 1 or IOM 27) and actuator (such as IOM
2 or IOM 31) portions of the system and other acces-
sories. Refer to the appropriate instructions when this
information is needed.
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.
WARNING: This product has electrical conduit
connections in either thread sizes 0.5-inch NPT or
M20 which appear identical but are not
interchangeable. Forcing dissimilar threads
Logix 500 Digital Positioner
Valtek Part No. ?????
together will damage equipment, cause personal
injury and void hazardous location certifications.
Conduit fittings must match equipment housing
threads before installation. If threads do not match,
obtain suitable adapters or contact a Flowserve
office.
WARNING: Standard industry safety practices
must be adhered to when working on this or any
other process control product. Specifically,
personal protective and lifting devices must be
used as warranted.
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.
2. In the event of shipping damage, contact the ship-
per immediately.
3. Should any problem arise, contact a Flowserve
Flow Control Division representative.
