WARNING: Not a Safeguarding Device
An Emergency Stop Device is not considered a safeguarding device because it requires an
overt action by an individual to stop machine motion or hazards.
A safeguarding device limits or eliminates an individual's exposure to a hazard without action by the
individual or others. Because an individual must actuate the device for it to function, these devices do
not fit the definition of a safeguarding device and cannot be substituted for required safeguarding. Refer
to the relevant standards to determine those requirements.
WARNING: Emergency Stop Functions
Do not mute or bypass any Emergency Stop device. ANSI B11.19, ANSI NFPA79 and IEC/EN
60204-1 require that the Emergency Stop function remain active at all times.

Mechanical Installation
• The rope should be easily accessible and visible along its entire length. Markers or flags may be fixed on the rope
to increase its visibility
• Switch body, anchor mounts and wire rope supports (pulleys or eye bolts) must be rigid and secure
• Although pulleys are preferred, a combination of pulleys and/or eye bolts are required to support the wire rope
along its length. When pulled, the wire rope, should move freely through the pulleys or eye bolts to actuate the
switch
• Use only pulleys (not eye bolts) when routing the rope around a corner or whenever direction changes, even
slightly
• Never run rope through conduit or other tubing
• Never attach weights to the rope
• Temperature affects rope tension. The rope expands (lengthens) when temperature increases, and contracts
(shrinks) when temperature decreases. Significant temperature variations require frequent checks of the tension
adjustment
• Do not exceed the maximum specified total rope length. Banner offers models for other spans; contact Banner
