Banner SI-QM100 Locking Style Switches - Manual (Page 3)

Mechanical Installation
The actuator head may be rotated, if desired, to any of four 90 degree posi-
tions. To reposition the actuator head, unscrew the four mounting bolts, turn
the head to the desired position, and re-tighten the bolts.
IMPORTANT: Verify the actuator is fully engaged before removing the actuator
head screws during the rotation process.
All mounting hardware is supplied by the user. The fasteners must be of suffi-
cient strength to avoid 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 accept M5 (#10) screws. There are
three holes on a standard limit switch mounting pattern of 30 x 60 mm. The two
mounting holes on the actuator are spaced 20 mm apart. The grommet and
sleeve design allows a small amount of movement (i. e., misalignment) when
the actuator engages the switch body. The sleeves accept M4.5 (#8) screws.
Position the switch, with its actuator fully engaged, in the mounting location and mark the mounting holes. Fasten the switch body and the
actuator in place. The non-adjustable in-line actuator includes floating sleeves in the mounting holes to allow some forgiveness for
switch-to-actuator alignment. Take care to not over-tighten the actuator fasteners so as to allow this movement. After the mounting hard-
ware is secure, check the actuator/switch engagement for misalignment and binding.
IMPORTANT: A safety switch must be installed to discourage tampering or defeat. Mount each switch to prevent bypassing of the switch-
ing function at the terminal chamber. A switch and its actuator must never be used as a mechanical stop.
Manual Release for Spring Lock Models

Manual
Release
(see text)
Models with solenoid unlock may be manually unlocked by depressing the button
located beneath the large hex cover screw on the switch body. The manual re-
lease button is only for emergency use when there has been system power loss
or solenoid failure. Access to the manual release button must be restricted by in-
stalling a security wire between the hole in the hex cover and the hole in the
screw immediately above the hex cover.
WARNING: Hazard Point
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 AN-
SI B11 standards for information on determining
safety distances and safe opening sizes for your
guarding devices.
Electrical Installation
WARNING: Series Connection of Safety Interlock Switches
Monitoring multiple guards with a series connection of safety interlock switches may result in a failure be-
ing masked or not detected at all. When such a configuration is used, periodic checks must be performed
regularly to verify proper operation. All failures must be immediately corrected ( e.g. immediately replacing
a failed switch), or the loss of the safety stop signal or an inappropriate reset could lead to serious injury or
death.
