Series 6A Operation & Maintenance – Introduction
INTRODUCTION
The Bray S6A is a microcontroller based positioner for pneumatic
actuators. The S6A converts an analog current signal into a
valve position pressure signal and offers positioner, valve and
actuator diagnostics using a variety of communication protocols.
Optional modules can be added for full range valve position
feedback, valve open/close verication, preset alarm warnings
and electromagnetic compatibility.
Principles of Operation
The operation of the S6A can be described in three parts; the user
dened setpoint, the pneumatic actuator air supply, and the S6A
internal controller. The user dened setpoint, which is provided
by the incoming analog signal or the communication protocol,
tells the positioner where to set the actuator. The pneumatic
actuators air supply provides the power to work the valve, and the
S6A internal microcontroller monitors the actuator position and
provides diagnostics to the end user.
When the microcontroller sees a deviation between the actual
position of the actuator and the provided setpoint it will pulse the
internal piezo electric valve in order to let air ll the corresponding
actuator chambers and drive the actuator from the pneumatic
supply lines. Once this deviation is within a desired tolerance or
“dead band” the microcontroller will stop the pulsing. Using this
process, the S6A only consumes air when it is needed, meaning it
will pay for itself within a short period of time.
Electrical Operation
The standard S6A requires 4 to 20mA loop power for all of the
internal electronics. It can be installed in a two wire, three wire,
or four wire architecture. There is no need to run separate power
and signal wiring. The S6A positioners with communication
modules get their power directly from the network. All of the
wiring diagrams for the different versions of the S6A and any
optional modules are shown in the “Field Connections” portion
of this manual.
Mechanical Operation
The S6A requires a pneumatic supply in the range of 20 - 102 psi
(1.4 - 7 BAR). Using this pneumatic supply, the S6A will position
the actuator and valve precisely where it needs to be to regulate
the process. Once in the settled state, the S6A has one of the lowest
air bleed rates in the market. The S6A requires a pneumatic supply rated at Class 2 in accordance with ISO 8573-1. An optional
lter can be installed upstream of the S6A to clean incoming air.
Diagrams are provided showing how to make the pneumatic connections in the “Field Connections”portion of this manual.

Series 6A Operation & Maintenance – Installation
INSTALLATION
Mounting to an Actuator
All Bray S6A positioners are suitable for mounting on Bray pneumatic actuators with the use of a standard mounting bracket. With
proper mounting hardware, the S6A positioner can be installed
onto other linear or quarter turn pneumatic actuators. The standard mounting position is to orient the unit directly over the
pneumatic actuator using the NAMUR mounting arrangement in
such a way that the LCD and pushbuttons are easily accessible.
If the positioner is to be mounted on a vertical pipe, it is recommended that the unit be positioned with the conduit entries on the
bottom to prevent condensation from entering the positioner by
way of conduit. In all cases, the conduit should be positioned to
prevent drainage into the positioner.
Tools Needed:
• 5mm Allen Key
• 5/16" Wrench
Parts Needed:
Item Qty.
The positioner should be mounted to
the actuator as follows:
1. Turn the positioner upside down and align the provided mounting bracket over the positioners output shaft. The bracket
should align with the four threaded holes around the output
shaft.
2. Using the 5mm allen key afx the mounting bracket to the
positioner using the four lockwashers and mounting bolts [A].
3. Turn the positioner right side up and position the output shaft
so that the atted side is facing you.
4. Insert the coupler over the output shaft, ensuring that the
couplers set screw is in alignment with the at of the shaft.
Tighten the couplers set screw.
5. Place the yellow indicator on the base of the coupler.
6. Mount the positioner on top of the actuator and tighten it using
the 5/16" wrench and the four mounting bolts [B].

FIELD WIRING
Each S6A is provided with two conduit entries for power/incoming analog signal of the main unit and any optional modules.
Please refer to the wiring diagrams referenced in this document when connecting the positioner and any optional modules.
It is essential to install the optional modules before connecting the positioner electrically. Refer to the following “Technical
Description” portion of this manual for relevant power distribution sizing information when installing a S6A positioner and its
optional modules.
Safety Notes:
• Local regulations regarding hazardous environments must be
followed when installing this device in a hazardous location.
• The conduit connections must be properly sealed to maintain
the weatherproof integrity of the actuator enclosure.
• Never connect the current input (terminals 6 and 7 as shown
on the diagrams to the right) to a power source; the positioner
will probably be destroyed in that case. Always use a current
source with a maximum output current of I = 20 mA.
• To maintain auxiliary power, the input current must be a minimum of 3.6 mA.
Note: The plastic enclosure is metallized from inside to
increase the electromagnetic compatibility (EMC) with
respect to high-frequency radiation. The shield is connected
to the threaded bush shown in Figure 1 such that it is electrically conductive. This protection is effective only if you
connect at least one of the bushes to the grounded control
valves through electrically conductive (bare) attachments.

Series 6A Operation & Maintenance – Field Connections
Connecting Pneumatic Supply Lines
Refer to the Technical Data portion of this manual for specications regarding air quality.
The S6A is equipped with three pneumatic connections, Y1, Y2
and PZ. PZ is for the pneumatic supply and Y1 and Y2 are used
to supply the pneumatic actuator. The S6A can also be equipped
with a pressure gauge block for monitoring supply and actuating
pressure and a lter to ensure that the S6A is receiving clean air.
Proceed as follows to make the pneumatic connections:
Refer to Figure 2.
Y1
PZ
Y2
E
Figure 2. - Pneumatic connection on the standard controller
1. If required, connect the pressure gauge block for supply air
and actuating pressure.
2. Connect supply air to PZ.
Connection using female thread G1/4 DIN 45141
or 1/4" NPT:
• PZ supply air 20psi to 102psi (1.4 to 7 bar)
• Y1: actuating pressure for single and double-acting
actuators
• Y2: actuating pressure for double-acting actuators
• E: exhaust air outlet; remove the attenuator if required.
For double-acting actuators, connect actuating pressures
Y1 or Y2 depending on the desired safety position. The
three pneumatic connections will go to the following
safety position in case of electrical auxiliary power supply failure:
• Y1: single-acting, depressurized
• Y1: double-acting, max. actuating pressure/supply air
pressure.
• Y2: double-acting, depressurized
Note: Besides continuous air consumption, the positioner may
try to compensate the position deviation due to leakage. This
will lead to premature wear in the entire control unit. To prevent
this ensure that all pneumatic connections are properly sealed
and perform regular maintenance on their ttings.

Restrictors
The S6A is equipped with air restrictors to reduce the air output to
achieve actuating times of T > 1.5 s for small actuators. Restrictors
1 and 2 are used for this purpose.
Tools Needed:
• Hexagon socket 2.5 mm
Refer to Figure 3.
When turned clockwise, they reduce the air output and nally shut
it off.
In order to set the restrictors, it is recommended to close them and
then open them slowly.
In case of double-acting actuators, ensure that both restrictors
have approximately the same setting.
Purging
The S6A is equipped with a purge air switch that allows the
actuator to purge air either inside of the unit or directly outside.
When the enclosure is open, the purge air switch above the
pneumatic terminal strip on the pneumatic block can be accessed.
Tools Needed:
• Instrument Screwdriver
Refer to Figure 4.
In the IN position, the enclosure is ushed from inside with a
small volume of clean and dry instrument air.
In the OUT position, the purge air is directed towards outside of
the unit.

Series 6A Operation & Maintenance – Field Connections
Natural Gas as an Actuator Medium
The S6A can also be operated with natural gas as an actuator
medium. When operating the positioner with natural gas, you
must follow and adhere to the following safety notes:
1. Only the “EEx ia” version of the positioner and optional
modules with the “EEx ia” type of protection may be operated
with natural gas. Positioners with other types of protection,
i.e. ameproof enclosures for zones 1 and 2 are not permitted.
2. Do not operate the positioner with natural gas in closed spaces.
3. Natural gas is continuously blown off in the servo-drive
depending on the model. Special care must therefore be taken
during maintenance activities near the positioner. Always
ensure that the immediate surroundings of the positioner are
adequately ventilated.
4. The mechanical limit switch module may not be used when
operating the positioner with natural gas.
5. Depressurize the devices operated with natural gas adequately
during maintenance activities. Open the cover in an explosionfree atmosphere and depressurize the device for at least two
minutes.
Normally you operate the positioner with compressed air. Natural
gas has been approved as an actuator medium for intrinsically
safe positioners with the “EEx ia” type of protection. Only use
natural gas which is clean, dry and free from additives.
The positioner releases the used natural gas through the exhaust
air outlet E (see Figure 2). The exhaust air outlet E is equipped
with an attenuator. As an alternative to this standard conguration,
the exhaust air outlet can be replaced with a G¼ screwed tting.
You have to dismantle the attenuator for this purpose. Natural gas
escapes parallel to the exhaust air outlet E, from the enclosure
vent at the bottom side of the device, and from the control air
outlet near the pneumatic connections. This escaping natural gas
cannot be collected and carried off. When using natural gas as an
actuator medium refer to Figure 5 for maximum bleed off values.
Optional Accessories
1. Pressure Gauges – used to measure and indicate supply and
actuating pressures
2. Filter – used to clean the supply medium
3. Non Contacting/External Position Detection System – used
for harsh environments
4. SIMATIC PDM Operation Software – used for online
diagnostics of the S6A
Contact your Bray representative for specic requirements for
your intended application.

Installing a New Unit
Please refer to the S6A Quick Start Guide for the Standard Unit.
Replacing a Unit
The S6A can be replaced in a running system where a S6A was
already in use without interrupting the process. By copying and
transferring the device and initialization data, it is possible to
commission a replacement positioner without needing to initialize it. The S6A uses the communication interface to transfer data.
When this is performed, it is crucial to perform a standard initialization of the replacement positioner as soon as possible because
the following properties can be ensured only after initializing:
• Optimum adjustment of the positioner as per the mechanical
and dynamic properties of the actuator.
• Unrestricted accuracy and dynamic behavior of the positioner.
• Deviation-free position of the hard-end stops.
• Accuracy of the maintenance data
Copy the initialization data and the device parameters as follows:
1. Read in the initialization data and the device parameters of the
positioner to be replaced. Use a suitable parameterization
tool for this purpose.
2. Save the data in the parameterization tool.
Note: If the positioner to be replaced has already been initialized
or congured using the parameterization tool, you need not read
in and save the device data.
Proceed as follows to replace a positioner in a running system:
3. Fix the actuator at its current position mechanically or
pneumatically.
4. Determine the actual position value.
– Read the actual position value on the digital display of
the positioner to be replaced.
Take note of the read value.
– If the electronic unit of the positioner is defective, mea-
sure the actual position value at the actuator or the valve.
Take note of the read value.
5. Dismantle the positioner.
6. Attach the lever arm of the positioner to be replaced to the
replacement positioner.
7. Install the replacement positioner on the control valve.
8. Set the transmission ratio selector of the replacement positioner
to the same position as that of the positioner to be replaced.
9. Use the parameterization tool to transfer the saved device and
initialization data to the replacement positioner.
10. If the displayed actual position value differs from the noted
value, correct the deviation by moving the friction clutch.
11. The replacement positioner is ready for operation when the
displayed and the noted values match.
Operation
Reading the LCD screen
The S6A digital display has two lines, one on the bottom and one
on top. Each element on the top line has seven segments while
each element on the bottom line has fourteen. Contents of the display depend on the selected mode. Figure 6 below provides an
example of what the display will look like when the unit is powered on.
Figure 6.
Example Display
Note: When operated in temperature ranges below 14°F (-10°C),
the liquid crystal display of the positioner becomes sluggish and
the repetition rate display is reduced considerably.
Using the pushbuttons
The S6A is manually operated using three pushbuttons. The cover
of the positioner has to be removed in order to operate the buttons.
Note: The function of the buttons depends on the current
Operating Mode. As a general rule the following applies:
The operating mode button is used to select the modes and to
forward the parameters.
The decrement button is used to select parameter values when
conguring. You can use this button to move the actuator in
the manual mode.
The increment button is also used to select parameter values
when conguring. You can use the increment button to move
the actuator in the manual mode.
+ *Parameters are activated in the reverse order by press-
ing the operating mode button and the decrement button at
the same time
Note: The IP66/NEMA 4x degree of protection is not ensured
as long as the positioner is open.

the “Conguration” mode with a congurable fault message. A
position feedback or display of limits A1 and A2 is not possible.
Note: If electrical auxiliary power supply fails when conguring,
the positioner responds as follows until the power supply is
reestablished:
• The positioner switches to the rst parameter.
• Settings of the values already congured are retained.
In order to save the changed parameter values, exit the
“Conguration” mode or switch to another parameter. When
the “Conguration” mode is restarted, the control in the digital
display switches to the last activated parameter.

P-manual mode (as-delivered condition)
The “P-manual mode” is preset for the positioner in the
as-delivered condition. The digital display of the positioner shows
the current potentiometer position in the upper line. “NOINI”
blinks in the second line of the digital display. You can move the
actuator using the decrement and increment buttons. Switch to
Conguration” and “Initialization mode” to adapt the actuator as
per the positioner.
Alarms or position feedbacks can be triggered only after
initializing the positioner completely.
Manual mode (MAN)
You can move the actuator using the decrement and increment
buttons in this mode. The setting selected here is retained
irrespective of the setpoint current and leakages, if any.
Note: To accelerate the actuator movement keep one of the
two direction buttons pressed and simultaneously press the
remaining direction. In the event of a failure of the power
supply, once the power is reestablished the positioner switches
to “Automatic” mode.

Series 6A Operation & Maintenance – Calibration & Commissioning
Automatic (AUT)
Automatic is the standard mode. In this mode, the positioner
compares the setpoint position with the actual position. The
positioner moves the actuator until the control deviation reaches
the congurable dead zone. A fault message is displayed if the
dead zone cannot be reached.
Diagnostics
Proceed as follows to call the “Diagnostics” mode from the
“Automatic” or “Manual” modes:
Press the three buttons of the positioner at the same time for at
least 2 seconds.
Current operating data can be called and displayed in this mode,
e.g.:
• Stroke number
• Number of changes in direction
Using the built in Diagnostics
The S6A has various monitoring functions with which changes on
the actuator and valve can be detected and signaled if applicable
when a selectable limit has been exceeded. This information may
be important for diagnosis of the actuator or valve and will help
to schedule preventative maintenance. The measuring data that is
monitored is listed below:
• Travel integral
• Number of changes in direction
• Alarm counter
• Self-adjusting dead zone
• Valve end limit position (for detection of valve seat wear or
deposits)
• Operating Hours (also according to temperature and travel
ranges) as well as min./max. temperature
• Operating Cycles of piezoelectric valves
• Valve positioning time
• Actuator leakages
The diagnostics display has similar structure to that of the
“Conguration” mode:
• The upper line shows the value of the diagnosis variable.
• The lower line shows the number and the abbreviation of the
displayed variable.
• Number of fault messages
Note: The “Automatic” and “Manual” modes remain set when
switching to the “Diagnostics” mode. The positioner responds
as per the set mode:
• The predened setpoint is used as a control variable in the
automatic mode.
• The last reached position is retained in the manual mode.
Some diagnostics values can be greater than 99999. In such a
case, the display switches over to the exponential view. Example:
The value “1234567” is shown as “1.23E6”.
In the event of a fault an error code will be shown on the lower
left hand corner of the display. There is a fault table in the
“Troubleshooting” section of this manual which explains what
each of these codes represents.
The following table provides an overview of values that can be
displayed. The last column contains “X” if the value can be set
to zero.

Installing the Alarm Module
Alarm Unit
Function
The alarm unit triggers fault messages and alarms using binary
outputs. The message function is based on the change in the signal status:
If the signal status is “HIGH”, there is no alarm message and the
binary inputs are conductive.
If the signal status is “LOW”, the module reports an alarm by
shutting down binary outputs using a high-resistance.
Due to the dynamic control, this module can report the arising
operational faults automatically. Set parameters 44 to 51 to activate and parameterize the output of alarms and fault messages.
Apart from binary outputs, the alarm unit has a double-acting
binary input BE2. Depending on the selected parameters, it is used
to block or to move the actuator it to its end position. Congure
the suitable settings on parameter 43.
Device features
The alarm unit has the following features:
6A O & M : 22
Available in two versions.
• Explosion-proof version for connecting to a switching
amplier in conformity with EN 60947-5-6.
• Non-explosion-proof version for connecting to power sources

Setting The Limits Of The Slotted Initiator Alarm Unit
You will require a suitable display device to determine the switch
status. For example, use the initiator tester type 2 / Ex by Pepperl
+ Fuchs.
1. Connect the display device to the following terminals of the
SIA unit:
• 41 and 42
• 51 and 52
2. Read the switch status of slotted initiators
Proceed as follows to set the limits:
1. Move the actuator to the rst desired mechanical position.
2. Adjust the upper actuating disc manually until the output
signal at terminals 41 and 42 changes. Set a high-low or a
low-high switch over as follows:
• Rotate the actuating disc beyond the switching point
until you reach the next switching point.
3. Move the actuator to the second desired mechanical position.
4. Adjust the lower actuating disc manually until the output
signal at terminals 51 and 52 changes. Set a high-low or a
low-high switch over as follows:
• Rotate the actuating disc beyond the switching point
until you reach the next switching point.
Note: The actuating discs are relatively difcult to move. This
design prevents their unintentional movement during operation.
You can achieve an easier and ner adjustment by reducing
friction temporarily. Move the actuator to and fro while
simultaneously holding the actuating discs.

TROUBLESHOOTING
During operation of the positioner, a few important values and parameters are continually monitored. In conguration mode, you can
congure that monitoring so that the fault message output will be activated if, for instance, a limit is exceeded. Information about what
events can activate the fault message output can be found in Figure 16
Fault See Table #:
In which mode does a fault occur?
Initialization 1
Manual and automatic modes 2, 3, 4, 5
In which environment and under which boundary conditions does a fault occur?
Wet environment (e.g. strong rain or constant condensation) 2
Vibrating (oscillating) control valves 2, 5
Impact or shock loads (e.g. vapor shocks or breakaway valves) 5
Moist (wet) compressed air 2
Dirty (contaminated with solid particles) compressed air 2, 3
When does a fault occur?

Figure 16. - Fault Messages
In automatic and manual mode, when the fault message output triggers the digital display shows what fault triggered the message.
The two digits on the lower left show the corresponding error code. If multiple triggers occur at the same time, they are displayed one
after the other cyclically. The device status, including all fault messages, can be called up using command “#48” over HART. For other
protocols please refer to their specic guide on www.bray.com.
You can use the advance diagnostics parameters to display fault messages in one, two or three stages. The three stage method uses
“trafc light signaling” symbolizing the type of fault occurring. The user will see either a green, yellow, or red wrench on their HMI in
relation to the S6A. Green indicates a need for maintenance, yellow an urgent need for maintenance and red indicates imminent danger
of unit failure or general failure. In addition to the fault message output, alarm outputs 1 and 2 are then used. For this purpose, set the
“XDIAG” parameter as described in Figure 17.
