Machine Safety Switches - SI-LS31R Series Limit Switch Style
Mechanical Installation
The actuator head may be rotated in increments of 90 degrees. With the actuator in the
home (0°) position, loosen the four screws holding the actuator head to the switch body.
Carefully lift the actuator head away from the spring and gasket and rotate it to the desired
position. Press the actuator head firmly down to compress the spring, and re-fasten the
four screws.
All mounting hardware is supplied by the user. Fasteners must be of sufficient strength
to guard against incidental breakage. Use of permanent fasteners or locking hardware is
recommended to prevent loosening or displacement of the actuator and switch body. The
mounting holes in the switch body and actuator accept M4 (#8) screws (see dimensions,
page 7).
Position the switch in the mounting location and mark the mounting holes. See Figure 2.
Drill the required holes and fasten the switch body and the actuator in place.
The outside diameter of the actuator shaft is 12.0 mm (0.47”). The inside diameter of the
shaft is 8.2 mm (0.32”). The shaft has a 3.5 mm (0.14”) diameter through-hole to allow
the shaft to be coupled to the hinge, using a drift pin (see dimensions, page 7).
IMPORTANT: A safety switch must be installed in a manner which discourages
tampering or defeat. Mount each switch to prevent bypassing of the switching function
at the terminal chamber.
WARNING . . .
It must not be possible for
personnel to reach any hazard point
through an opened guard (or any
opening) before hazardous machine
motion has completely stopped. Please reference
OSHA CFR 1910.217 and ANSI B11 standards
(see page 2) for information on determining safety
distances and safe opening sizes for your guarding
devices.
