PRINCIPLES OF OPERATION
1.8 Basic Operation
The Logix 500+ digital positioner is a two-wire 4-20 mA input
digital valve positioner which uses the HART protocol to
allow two-way remote communications. The positioner is
completely powered by the 4-20 mA input signal. Start-up
current must be at least 3.8 mA. The positioner is
configurable through the local user interface, hand-held or
DTM. The Logix 500+ positioner can control both doubleand single-acting pneumatic actuators with linear or rotary
mountings.
The Logix 500+ digital positioner is an electronic and
pneumatic closed-loop feedback instrument. Figure 1 s hows
a schematic of a Logix 500+ positioner installed on a singleacting linear actuator for air-to-open action. Figure 2 shows
the feedback algorithm.
1.9 HART
The Logix 500+ receives power from the two-wire, 4-20 mA
input signal. However, since this positioner utilizes HART
communications, two sources can be used for the command
signal: Analog and Digital. In Analog source, the 4-20 mA
signal is used for the command source. In Digital source, the
level of the input 4-20 mA signal is ignored (used only for
power) and a digital signal, sent via the HART
communication protocol, is used as the command source.
The command source can be accessed with ValveSight
software, the HART 375 communicator, or other host
software. See section 11 HART COMMUNICATION for more
information.
1.10 Position Definition
Whether in Analog or Digital Source, The position at 0% is
always defined as the valve in a closed position and 100% is
always defined as the valve in an open position. In Analog
Source, the 4-20 mA signal is converted to a position (in
percent). During loop calibration, the signals corresponding
to 0% and 100% are defined.
1.11 Command Input and Final Command
The Command Input signal (in percent) passes through a
characterization/limits modifier block. This function is done in
software, which allows for in-the-field customer adjustment.
The characterization block can apply no adjustment (Linear),
one of several pre-defined characterization curve
adjustments (including several Equal Percent), or a 21-point
Custom Characterization curve adjustment. In Linear mode,
the input signal is passed straight through to the control
algorithm in a 1:1 transfer. In Equal Percent (=%) mode, the
input signal is mapped to a standard rangeability equal
percent curve. If Custom Characterization is enabled, the
input signal is mapped to a custom, user-defined 21-point
output curve. The custom user-defined 21-point output curve
is defined using a handheld or ValveSight software. In
addition, two user-defined features, Soft Limits and Tight
Shutoff may affect the position. The actual command being
used to position the stem after the evaluation of
characterization curves and user limits, is called the Final
Command.
1.12 Outer Loop
The Logix 500+ uses a two-stage, stem-positioning
algorithm. The two stages consist of an inner-loop (pilot relay
control) and an outer-loop (stem position control). Referring
again to Figure 1, a stem position sensor provides a
measurement of the stem movement. The Final Command is
compared against the Stem Position. If any deviation exists,
the control algorithm sends a signal to the inner-loop control
to move the relay in a direction, depending upon the
deviation. The inner-loop then quickly adjusts the spool
position. The actuator pressures change and the stem
begins to move. The stem movement reduces the deviation
between Final Command and Stem Position. This process
continues until the deviation goes to zero.

1.13 Inner Loop
The inner-loop controls the position of the relay valve by
means of a driver module. The driver module consists of a
temperature-compensated hall-effect sensor and a Piezo
valve pressure modulator. The Piezo valve pressure
modulator controls the air pressure under a diaphragm by
means of a Piezo beam bender. The Piezo beam deflects in
response to an applied voltage from the inner-loop
electronics. As the voltage to the Piezo valve inc reases, the
Piezo beam bends, closing off against a nozzle causing the
pressure under the diaphragm to increase. As the pressure
under the diaphragm increases or decreases, the spool or
poppet valve moves up or down respectively. The Hall Effect
sensor transmits the position of the spool or poppet back to
the inner-loop electronics for control purposes.
1.14 Detailed Sequence of Positioner Operations
A more detailed example explains the control function.
Assume the unit is configured as follows:
• Unit is in Analog command source.
• Custom characterization is disabled (therefore
characterization is Linear).
• No soft limits enabled. No MPC set.
• Valve has zero deviation with a present input signal of
12 mA.
• Loop calibration: 4 mA = 0% command, 20 mA = 100%
command.
• Actuator is tubed and positioner is configured air-to-
open.
Given these conditions, 12 mA represents a Command
source of 50 percent. Custom characterization is disabled so
the command source is passed 1:1 to the Final Command.
Since zero deviation exists, the stem position is also at 50
percent. With the stem at the desired position, the spool
valve will be at a middle position that balances the pressures
above and below the piston in the actuator. This is commonly
called the null or balanced spool position.
Assume the input signal changes from 12 mA to 16 mA. The
positioner sees this as a command source of 75 percent.
With Linear characterization, the Final Command becomes
75 percent. Deviation is the difference between Final
Command and Stem Position: Deviation = 75% - 50% =
+25%, where 50 percent is the present stem position. W ith
this positive deviation, the control algorithm sends a signal to
move the spool up from its present position. As the spool
moves, the supply air is applied to the bottom of the actuator
and air is exhausted from the top of the actuator. This new
pressure differential causes the stem to start moving towards
the desired position of 75 percent. As the stem moves, the
Deviation begins to decrease. The control algorithm begins to
reduce the spool opening. This process continues until the
Deviation goes to zero. At this point, the spool wil l be back in
its null or balanced position. Stem movement will stop and
the desired stem position is now achieved.
1.15 Inner Loop Offset
The position of the spool (or poppet) at which the pressures
are balanced, holding the valve position in a s teady state, is
called the Inner Loop Offset. The controlling algorithm uses
this value as a reference in determining the Piezo voltage.
This parameter is important for proper control and is
optimized and set automatically during stro ke calibration.

4 STORAGE AND UNPACKING
4.1 Storage
FLOWSERVE Control valve packages (a control valve and
its instrumentation) are typically well protected from
corrosion. Nevertheless FLOWSERVE products must be
stored in a clean, dry environment such as an enclosed
building that affords environmental protection. Heating is not
required. Control valve packages must be stored on suitable
skids, not directly on the floor. The storage location must also
be free from flooding, dust, dirt, etc. Plastic caps are fitted to
protect the flange faces and positioner ports to prevent the
ingress of foreign materials. These caps should not be
removed until the valve or positioner is actuall y moun ted i nto
the system.
If FLOWSERVE products (especially sealing materials) have
been in storage for longer periods check these for corrosion
or deterioration before using these products. Fire protection
for FLOWSERVE products must be provided by the end
user.
4.2 Unpacking
While unpacking the valve and/or Logix 500MD+ positioner,
check the packing list against the materials received. Lists
describing the system and accessories are included in each
shipping container.
In the event of shipping damage, contact the shipper
immediately. Should any problems arise, contact a Flowserve
Flow Control Division representative.
4.3 Pre-installation Inspection
When installing a positioner, verify the shaft has not been
damaged and that the plugs and cover are in place. The
plugs keep debris and moisture from damaging the internal
components of the positioner. If the positioner has been
contaminated, clean the positioner components gently with a
soft damp cloth. Some components may be removed for
better access. See section 17 MAINTENANCE AND
REPAIR. When cleaning a Double Acting Relay (Spool and
Block) take care not to bend or force the spool. A Single
Acting Relay may be removed, but do not disassembled the
relay. Check connectors to ensure that no debris is present.
Port screens can be removed with a flat screwdriver for
access to internal passages.

5 MOUNTING AND INSTALLATION
5.1 Mounting to Mark One Linear Valves
To mount a Logix 500+ positioner to a Valtek linear Mark
One valve, refer to Figure 4: Mounting to Mark I Linear
Valves and proceed as outlined below.
1 Remove washer and nut from follower pin assembly.
Insert pin into the appropriate hole in follower arm,
based on stroke length. The stroke lengths are stamped
next to their corresponding holes in the follower arms.
Make sure the unthreaded end of the pin is on the
stamped side of the arm. Reinstall lock washer and
tighten nut to complete follower arm assembly.
2 Slide the slot in the follower arm assembly over the flats
on the position feedback shaft in the back of the
positioner. Make sure the arm is pointing toward the
side of the positioner with ports A, B, and Supply. Slide
the lock washer over the threads on the shaft and
tighten down the nut.
3 Align the bracket with the three outer mounting hol es on
the positioner. Fasten with 1/4" bolts.
4 Screw one mounting bolt into the hole on the yoke
mounting pad nearest the cylinder. Stop when the bolt
is approximately 3⁄16" from being flush with mounting
pad.
5 Slip the large end of the teardrop shaped mounting hole
in the back of the positioner/bracket assembly over the
mounting bolt. Slide the small end of the teardrop under
the mounting bolt and align the lower mounting hole.
6 Insert the lower mounting bolt and tighten the bolting.
7 Position the take-off arm mounti n g sl ot aga i ns t t he s te m
clamp mounting pad. Apply Loctite 222 to the take-off
arm bolting and insert through washers into stem
clamp. Leave bolts loose.
8 Slide the appropriate pin slot of the take-off arm, based
on stroke length, over the follower arm pin. The
appropriate stroke lengths are stamped by each pin
slot.
NOTE: The feedback shaft has a clutch mechanism that
allows for over-rotation of the shaft for easy adjustments.
9 Center the take-off arm on the rolling sleeve of the
follower pin.
10 Align the take-off arm with the top plane of the stem
clamp and tighten bolting. Torque to 120 in-lb.
NOTE: If mounted properly, the follower arm should be
horizontal when the val ve is at 50 % stroke and should move
approximately ±30° from horizontal over the full stroke of the
valve. If mounted incorrectly, a stroke calibration error will
occur and the indicator lights will blink a RGGY code
indicating the position sensor has gone out of range on one
end of travel or the travel is too small. Reposition the
feedback linkage or rotate the position sensor to correct the
error.
NOTE: To virtually eliminate non-lin ear it y, use the
Linearization feature in the Custom Characterization page of
the DTM.

switches accordingly. See section 8 STARTUP.
12 Pre ss the QUICK-CAL/ACCEPT button for three to four
seconds or until the positioner begins to move. The
positioner will now perform a stroke calibration.
13 If the calibration was successful the green LED will blink
GGGG or GGGY and the valve will be in control mode.
14 If calibration fails, as indicated by a RGGY blink code,
retry the calibration. If it still fail s, the feedback values
were exceeded and the arm must be adjusted away
from the positioner’s limits. Rotate the feedback shaft
so that the full free travel of the feedback shaft is in the
range of the actuator movement. Optionally, continue
to attempt the calibration. Each calibration attempt
adjusts the acceptable limits and it should pass
eventually.
CAUTION: Remember to remove the air supply before
re-adjusting take-off arm.
NOTE: If mounted properly, the follower arm should be
horizontal when the valve is at 50% stroke and should move
approximately ±30° from horizontal over the full stroke of the

5 Pre-assemble the mounting bracket on the left actuator
leg and hand-tighten the two U-bolts, nuts and lockwashers.
6 Attach the positioner to the pre-ass emb led mount i ng
bracket and fasten it with two hexagon screws and two
lock washers. Check that the follower pin is inserted in
the slot of the take-off arm and the follower arm is
positioned parallel to the take-off arm.
7 Tighten all screws and nuts.
NOTE: The feedback shaft has a clutch mechanism that
allows for over-rotation of the shaft for easy adjustments.
Figure 17: Mounting to a Linear Actuator
NOTE: A slight unsymmetrical mounting increases
the linearity deviation but does not affect the performance of
the device.
NOTE: Depending on the actuator size and stroke it may
be necessa ry to flip the take-off arm (Figure 3) by 180° and
attach it to the opposite side of the stem clamp bracket.

6 TUBING
After mounting has been completed, tube the positioner to
the actuator using the appropriate compression fitting
connectors. For best performance, use 10 mm (3/8 inch)
tubing for 645 square cm (100 square inch) actuators or
larger.
6.1 Determine Air Action
The port labeled “Y1” delivers air when an air supply is
present and the relay is energized. (For positioners with
double acting relays, this is port A. For positioners with
single acting relays, this is port B.) Typically, the port labeled
“Y1” should be tubed to the pneumatic side of the actuator
(the side that would result in the air compressing the actuator
spring). When tubed this way, the spring is designed to
return the valve to the fail safe state should supply air or
power to the unit fail.
Tube the port labeled “Y1” to the side of the actuator that
must receive air to begin moving away from the fail safe
state.
If air from “Y1” should open the valve, set the Air Action
configuration switch on the positioner to Air-to-Open,
otherwise set it to Air-to-Close.
The Air-to-Open and Air-to-Close selection is determined by
the actuator tubing, not the software. When air action
selection is made during configuration, the sel ection t ells the
control which way the actuator has been tubed.
If the valve is double acting, port the valve labeled “Y2” to the
other side of the actuator.
DANGER: Proper tubing orientation is critical for the
positioner to function correctly and have the proper failure
mode.
Example: Tubing Linear Double-Acting Actuators
For a linear air-to-open actuator, the “Y1” port of the
positioner is tubed to the bottom side of the actuator (closest
to the valve). The “Y2” port of the positioner is tubed to the
top side of the actuator. For a linear air-to-close actu ator the
tubing configuration is reverse d.
Figure 18: Tubing Linear, Double Acting, Air to Open
Example: Tubing Rotary Double-Acting Actuators
For a rotary actuator, the “Y1” port of the positioner manifold
is tubed to the far side of the actuator. The “Y2” port of the
positioner manifold is tubed to the side of the actuator closer
to the transfer case. This tubing convention is followed
B (Y2)
A (Y1)
regardless of air action. On rotary actuators, the transfer
case orientation determines the air action.
Figure 19: Tubing Rotary, Double Acting, Air to Open
Example: Tubing Single-acting Actuators
For single-acting actuators, the “Y1” port is always tubed to
the pneumatic side of the actuator regardless of air action. If
a double acting (spool style) relay is installed in the
positioner, plug port B (Y2). If a single acting - poppet style
relay is installed, plug port A (Y2). Or, port A may be used
for purging. See
Figure 20: Tubing Linear, Single Acting, Air to Open
Purging Single Acting Actuators below.

A (Y1)
B (Y1)
A (Y2) Plug
6.2 Connect Supply Port
The positioner ports are threaded with either G ¼ or ¼
NPTF as indicated on the housing.
In order to maintain the recommended air quality, a
coalescing filter should always be installed in the supply gas
line. An air filter is highly recommended for all applications
where dirty air is a possibility. The positioner passage ways
are equipped with small filters, which remove medium and
coarse size dirt from the pressurized air. If necessary, they
are easily accessible for cleaning.
A supply regulator is recommended if the customer will be
using the diagnostic features of the Logix 500+ but is not
required. In applications where the supply pressure is higher
than the maximum actuator pressure rating a supply
regulator is required to lower the pressure to the actua tor’s
maximum rating.
6.3 Purging Single Acting Actuators
Purging allows the non-pressurized side of a single acting
actuator to fill with exhaust gas instead of atmospheric air.
This configuration helps prevent corrosion of actuator
components in harsh environments. When a single acting
