General Installation Steps
1.
Drill and tap out pulley shaft to a depth of 25 mm (1") concentric to its centerline, and
tap M12x1.75. If using magnetic connector, mount to shaft face, and go to step 3.
WARNING: Exercise caution when completing step 1, and remain
within specified tolerances.
2.
Thread the SITRANS WS100 onto the machine shaft using 16 mm or 5/8" open-ended
wrench and releasable thread-locking adhesive (Loctite or similar).
3.
Attach arrestor strap to an existing support member or add a rigid support if
necessary.
4.
Encase wiring in flexible conduit to allow unit to move freely (without tension on the
wires).
5.
Wire the SITRANS WS100 to the integrator. See Terminal Connections to Siemens
Integrators on page 12 for terminal post connections.
