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 mount-
ing 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 conden-
sation 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:

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 affix 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 flatted side is facing you.
4. Insert the coupler over the output shaft, ensuring that the
couplers set screw is in alignment with the flat 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].
