StoneL Prism series Installation & Adjusting Instructions

Prism™ Mounting
1. Thread the Trigger Shaft onto the actuation system stem.
2. Place provided o-ring in groove on the bottom of the
Mounting Coupler and slide over the Trigger Shaft.
Secure Mounting Coupler to the actuation system.
Fastening of Mounting Coupler to the actuation system
will be either flange mounted or threaded. (Dependent on
manufacturer of valve assembly)
3. Remove the Prism's Cover.
4. Slide the Prism Switch Assembly over the Trigger Shaft
via the Mounting Coupler socket located on the bottom of
the Switch Assembly. Do not seat the Switch Assembly
onto the Mounting Coupler. The Trigger Shaft should
now be approximately midway between upper and lower
Cam Stops on the Dual Module. (See Detail A)
5. While supporting the Switch Assembly with one hand,
place the two Trigger Cams onto the Trigger Shaft
between the cam stops. (See Detail A)
6. Fully seat the Switch Assembly onto the Mounting
Coupler. Secure the Switch Assembly to the Mounting
Coupler by tightening the set screw located on the
bottom of the Switch Assembly, opposite of the conduit
entries. Some mounting systems for 2" and larger
valves may have the Trigger Shaft threaded, in these
cases thread the provided 6/32 screw into the top of
the Trigger Shaft. (See Inset - AA)
7. To set the Cam Triggers, slide the upper trigger until it
touches the upper cam stop (or 6/32 screw) and push
down the lower trigger until it touches the lower cam
stop. Cycle the actuator and the triggers will
automatically be set to the proper position. (See Detail B)
8. Perform applicable field wiring and replace Prism Cover.
