Introduction
Flowserve’s BUSwitch™uses the FOUNDATION
®
Fieldbus communication protocol to operate
pneumatic valve actuators and monitor/report their
position. BUSwitch™also provides an odometer and
stroke timer to assist in preventative maintenance.
Principles of Operation
BUSwitch™utilizes two discrete output function
blocks (DO-1 and DO-2) to energize piezo or
coil actuators, which act as pilots to shift a large
capacity spool valve.For spring retur n and double
acting applications with a desired fail position (open
or closed) DO-1 is used to operate a single pilot.
For applications requiring fail in last position,
both DO blocks are used with a “dual coil” pilot
configuration.
In dual coil mode, users may choose to de-energize
piezo/coil elements after the valve has reached its
desired position or may configure the elements to
remain energized (factory default)(see “Transducer
Block”).
Valve position is sensed with two limit switches.
BUSwitch™communicates the state of these limits
in the transducer block’s SOLENOIDE_CLOSED
and SOLENOIDE_OPENED parameters and in the
READBACK_D parameters of DO-1 and DO-2.
The transducer block’s ODOMETER parameter tracks
the number of valve strokes. It may be reset using
RESET_ODOMETER.
The transducer block’s transition alarm alerts the
used if the stroke time exceeds the time in the
parameter TIME_OUT, this alarm is also passed
to the OUT_D of the DI-1 block.
Two discrete input blocks are factory-configured.
DI-1 is a discrete value indicating the stroke exceeded
a specific time. DI-2’s OUT_D parameter provides a
link to an external dry-contact input (terminal P4).
This input is jumper-selectable to normally open or
normally closed (jumper J1/J2). Common uses for
this input include valve packing pressure monitoring.
A 2-wire cable using the FF H1 (31.25 Kbps)
protocol provides communication and power to the
FF Communication Board.The communications
board, switches, and piezo/coil pilots are all
connected to an interface board.Two versions
of this interface card are available:
• 2-Wire for bus-powered pilot applications.
Utilizes ultra-low power piezo pilot valves.
• 4-Wire for externally powered pilot applications.
Utilizes a wide range of 24VDC coil pilot valves.
The communications card operates from 9.5 to
32 VDC. BUSwitches are configured to draw
18 mA of current. Current consumption from the
fieldbus segment will remain constant whether a
piezo/coil actuator is activated or not.

Start-up Guide
CAUTION
The BUSwitch™may cycle during a configuration download. Exercise caution in handling
valves that may be stroked during these
procedures.
For best results, Flowserve strongly recommends reading this entire document before
attempting to configure and commission
BUSwitches.
1 Following the instructions in “Mechanical
Installation,” install the BUSwitch™onto a
pneumatic actuator and turn supply air on.
2. Following the instructions in “Electrical connections,” connect fieldbus and optional dry-contact
wiring.
3. Referring to control system or configuration system
documentation, install BUSwitch™device description (DD) files onto system hard drive. Note:
Readme file on DD floppy contains instructions.
Note: For Fisher DeltaV systems, the DD files
must be copied to a directory or folder named
“464C4F” in order for the system to find them.
4. Initialize communications with device and bring
up the “Live List.” BUSwitches have been
configured from the factory with an ID of
“464C4F5053:BUSWITCH: [serialnumber]” and
a default tag of “FLOWSERVE BUSWITCH.”
Note the serial number.
5. Change the BUSwitch™attribute Device ID to the
value noted in step 4 and change the Device Tag
to the appropriate value.
6. Assign the Tag configuration in step 5.
7. BUSwitches are shipped with resource block,
transducer block, (2) DO blocks and (2) DI blocks
pre-configured unless specially configured by
agreement with customer.Refer to the appropriate
sections in this manual for the default configuration.
Make any desired changes to this configuration
and download.

8. Using the DO-1.OUT_D value parameter (and
DO-2.OUT_D for dual coil mode), stroke the valve
(Discrete 0 = de-energized; Discrete 1 = energized)
and set limit switches, referring to “Adjustment of
Switch Cams” section. Circuit board mounted LED’s
light when switches are tripped.
9. This is the minimum configuration to operate
the actuator and read valve position.Refer to
FOUNDATION®Fieldbus standards for DO and DI
blocks to establish more sophisticated control
strategies. Refer to the block sections in this manual
for more information on BUSwitch™functionality.
Mechanical Installation
BUSwitch™Mounting:
1. Installation is best performed with Flowserve
NAMUR mounting kits.These kits allow direct
mounting of the BUSwitch™shaft to the actuator
pinion without a coupler.The NAMUR mounting
kits will work with any actuator conforming to the
NAMUR standard for accessory mounting hole
locations and pinion dimensions. Simply attach the
bracket to actuator and BUSwitch™to the bracket
with the included fasteners.The BUSwitch™shaft
features an integral alignment pin that engages the
tapped pinion hole. Flowserve also offers a full line
of non-NAMUR mounting kits.
Spool and Tubing Configuration:
The following instructions apply to BUSwitch™configured with integral pilot valves and spool valve.For
non-integral pilot/spool valves, follow manufacturer's
instructions for piping.
1. For spring return actuators, a 4-way spool valve is
provided with port #2 plugged. For double acting
actuators, the same valve is provided with no
plugs. Make sure the correct spool is selected
before installing tubing.
2. Make sure all air pressure is removed before
installing tubing.
3. Attach tubing according to Figures 1 or 2 at right,
depending upon application. Attach supply tubing
to Port 1 and use 3 and 5 for exhaust.
4. To prolong actuator life use only clean, dry plant
air.Lubricated air is not required, although it is recommended, particularly for high cycle applications.

Lubrication
All BUSwitch™spool valves are pre-lubricated
and will operate dry (with no additional lubrication).
The use of lubricated air will not interfere with the
functioning of the BUSwitch™. If air lubrication
is used, the oils listed below are popular, easily
obtainable, fluids that are recommended for use
with the BUSwitch™spool valve:Gulf Harmony 47,
Mobil DTE Medium, Shell Tellus 29, Texaco Rondo B,
Sohivis 47 and Sunnis 921. Many other lubricants are
acceptable providing they do not contain detergents
that will attack Buna N or Viton Seals.

Electrical Connections
CAUTION
To prevent ignition of hazardous atmospheres, keep cover bolts tight while circuits
are live. Disconnect supply circuit before
opening.
Entry into the BUSwitch™housing is made through
three 1/2
” NPT conduit entries. Figures 3 and 4
provide terminal locations on the interface card.
Connection of the data cable is made to connector
P3 – observing polarity.Incorrect polarity will not
damage the electronics, but it will prevent communication. For hazardous locations, Underwriters
Laboratories (UL) and the National Electric Code
(NEC) require an approved sealing fitting within
eighteen inches of the switch enclosure.Sealing
fittings are not required for Division 2 non-incendive
applications.
CAUTION
Make sure power is turned off when making
electrical connection. Inadvertent power
cycling will result in BUSwitch
™
shutdown.
After a power shut-down wait at least five
seconds before attempting to turn power
back on to assure BUSwitch™start-up.
Open conduit entries must be closed after installation
using a close-up plug approved for hazardous
locations. Conduit and plugs must fully engage
five threads.
Ter minal P4 is provided for the input of a signal from
an external dry-contact switch. Jumper J1 and J2
change the configuration of this input. Factory setting
is Normally Closed with DI-2 OUT_D value Discrete
1 = contact open and Discrete 0 = contact closed.
Change the jumper setting to “normally open” for
Discrete 0 = contact open.
