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
F
OUNDATION ® 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 ™ config-
ured 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 rec-
ommended, 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.
