GENERAL INFORMATION
1.1
Using This Document
 
Product users and maintenance personnel should thoroughly 
review this manual prior to installing, operating, or performing 
any maintenance on the positioner. 
 
The following instructions are designed to assist in 
unpacking, installing and performing maintenance as 
required on Logix® 500MD+ positioners. Series 500 is the 
term used for all the positioners herein; however, specific 
numbers indicate features specific to model (i.e., Logix 520 
indicates that the positioner has HART® protocol). See Logix 
500MD+ Model Number table in this manual for a breakdown 
of specific model numbers. 
 
Separate Flow Control Products User Instructions cover the 
valve, actuator, or portions of the system and other 
accessories. Refer to the appropriate instructions when this 
information is needed. In most cases FLOWSERVE valves, 
actuators and accessories are designed for specific 
applications with regard to medium, pressure and 
temperature. For this reason they should not be used in other 
applications without first contacting the manufacturer. 
 
To avoid possible injury to personnel or damage to positioner 
parts, DANGER and CAUTION notes must be strictly 
followed. 
 
1.2
Terms Concerning Safety
 
The safety terms DANGER, CAUTION and NOTE are used 
in these instructions to highlight particular dangers and/or to 
provide additional information on aspects that may not be 
readily apparent. 
 
NOTE: Indicates and provides additional technical
information, which may not be very obvious even to qualified 
personnel. 
CAUTION: Indicates that minor personal injury and/or
property damage can occur if proper precautions are not 
taken. 
 
 
DANGER: Indicates that death, severe personal injury
and/or substantial property damage can occur if proper 
precautions are not taken. 
Compliance with other, not particularly emphasized notes, 
with regard to assembly, operation and maintenance and 
technical documentation (e.g., in the operating instruction, 
product documentation or on the product itself) is essential in 
order to avoid faults, which in themselves might directly or 
indirectly cause severe personal injury or property damage. 
 
1.3
Protective Clothing
FLOWSERVE positioners use high pressure gas to operate. 
Use eye protection when working around pressurized 
equipment. Follow proper procedures for working with 
natural gas if it is used. 
 
DANGER: Standard industry safety practices must be
adhered to when working on this or any process control 
product. Specifically, personal protective equipment must be 
used as warranted. 
 
 
 
1.4
Qualified Personnel
Qualified personnel are people who, on account of their 
training, experience, instruction and their knowledge of 
relevant standards, specifications, accident prevention 
regulations and operating conditions, have been authorized 
by those responsible for the safety of the plant to perform the 
necessary work and who can recognize and avoid possible 
dangers. 
 
In unpacking, installing and performing maintenance as 
required on FLOWSERVE products, product users and 
maintenance personnel should thoroughly review this manual 
prior to installing, operating or performing any maintenance. 
1.5
Valve and Actuator Variations
These instructions cannot claim to cover all details of all 
possible product variations, nor can they provide information 
for every possible example of installation, operation or 
maintenance. This means that the instructions normally 
include only the directions to be followed by qualified 
personal where the product is being used for its defined 
purpose. If there are any uncertainties in this respect 
particularly in the event of missing product-related 
information, clarification must be obtained via the appropriate 
Flowserve sales office. 
 
1.6
Spare Parts
 
Use only FLOWSERVE original spare parts. FLOWSERVE 
cannot accept responsibility for any damages that occur from 
using spare parts or fastening materials from other 
manufactures. If FLOWSERVE products (especially sealing 
materials) have been in storage for longer periods check 
these for corrosion or deterioration before using these 
products. See section 4 STORAGE AND UNPACKING more 
information. 
 
1.7
Service / Repair
 
To avoid possible injury to personnel or damage to products, 
safety terms must be strictly adhered to. Modifying this 
product, substituting non-factory parts, or using maintenance 
procedures other than outlined in this instruction could 
drastically affect performance and be hazardous to personnel 
and equipment, and may void existing warranties. 
 
Between actuator and valve there are moving parts. To avoid 
injury FLOWSERVE provides pinch-point-protection in the 
form of cover plates, especially where side-mounted 
positioners are fitted. If these plates are removed for 
inspection, service or repair special attention is required. 
After completing work the cover plates must be refitted. 
 
Logix 500+ positioner repair is limited to the replacement of 
sub-assemblies and circuit boards with FLOWSERVE-
manufactured replacements as outlined in this manual. 
 
DANGER: Substitution of with non-factory positioner
components may impair intrinsic safety.
CAUTION:
Before products are returned to
FLOWSERVE for repair or service, FLOWSERVE must be 
provided with a certificate which confirms that the product 
has been decontaminated and is clean. FLOWSERVE will 
not accept deliveries if a certificate has not been provided (a 
form can be obtained from FLOWSERVE). 
Apart from the operating instructions and the obligatory 
accident prevention directives valid in the country of use, all 
recognized regulations for safety and good engineering 
practices must be followed.
