2 Assembly and mounting
2.1 Instructions
Steps
Refer to Prism PI assembly gure on page8 when performing
mounting and assembly procedures. Prism PI unit and mounting kit
are supplied separately. From Prism PI shipping container, ensure
items A, and F are present. From the mounting kit, ensure items G, H, I,
and J are present.
1. From the mounting kit package, locate the trigger shaft (ItemG),
Prism mounting plate (ItemJ), and mounting plate fasteners
(ItemH). Ensure unit O-ring (Item I) and mounting plate O-ring
(ItemK) are present in the mounting plate.
2. Thread the trigger shaft into the actuator (ItemL) (it is
recommended that a drop of blue Loctite® be used on the trigger
shaft threads). Tighten to approximately 15 - 20 in.lbs (1.7 - 2.3Nm)
with a small adjustable wrench.
3. Place the mounting plate onto the actuator and fasten down with
provided screws (2-4). (use of blue Loctite® on these screws is
optional). Tighten to approximately 15 - 20 in.lbs (1.7 - 2.3Nm).
4. Take o cover (ItemB) and remove the trigger assembly (ItemF)
from within the unit.
5. Place Prism PI unit (ItemA) onto the mounting plate in the
orientation desired (Prism PI body can be rotated on the mounting
plate in 45° increments). Tighten the two body screws (ItemD)
with a M3 allen wrench to approximately 25 - 30 in.lbs (2.8 -
3.4Nm).
6. Back out the trigger assembly adjustment screw (ItemE)
approximately ⁄” with a M2 allen and place the trigger assembly
into the corresponding slot of the sensing module (ItemC), with
a nger, press down rmly onto the trigger assembly shaft (See
Detail-Fig.1).
7. Turn the trigger assembly adjustment screw until the yellow marks
on the trigger assembly are ush with the yellow marks on the
sensing module (See Detail-Fig.2) To remove trigger assembly
from shaft, turn in adjustment screw until released.
8. After all wiring and sensor setting procedures have been
completed, re-install cover and place unit in service.
Special notes:
• Mounting of the Prism PI requires a StoneL mounting kit specic to
the actuator the Prism PI is to be mounted to.
• In high cycle or high vibration applications, blue Loctite® may
be used on the Trigger shaft threads (ItemG) and the Prism PI
mounting plate screws (ItemH).
• It is highly recommended that exhaust port E be tted with a low
restriction muer or breather vent cap to prevent ingestion of
water or debris into the pneumatic valve.
