RP-QM90 Series Rope Pull Switches

62086

Datasheet

•
Positive-opening safety contacts (IEC 60947-5-1), not dependent

upon springs

• Contacts latch open when rope is pulled; requires manual reset

• Heavy-duty die cast metal housing, rated IP65, suitable for demanding

industrial environments

• Rope spans up to 100 m (330 ft), with the switch mounted in the center

of the span

• Both safety contacts are closed with normal rope tension, and open when

rope is pulled or if rope breaks (or if tension is reduced from normal
amount)

• Extra contacts for monitoring or to provide dual-channel input to a safety

module

• Switch actuator position clearly indicates when rope has proper tension

for operation

• Long life, switch rated at 1 million mechanical operations, minimum

•
Protective Earth Terminal (IEC 60947-1)

Regarding the Use of Rope Pull Switches. In the United States, the functions that Banner rope pull switches are

intended to perform are regulated by the Occupational Safety and Health Administration (OSHA). Whether or not any
particular rope pull switch installation meets all applicable OSHA requirements depends upon factors that are beyond the
control of Banner Engineering Corp. These factors include the details of how the switches are applied, installed, wired,
operated, and maintained.

Banner Engineering Corp. has attempted to provide complete application, installation, operation, and maintenance
instructions in this document. Direct any questions regarding the use or installation of rope pull switches to the factory
applications department.

RP-QM90 Series Rope Pull Switches

Banner Engineering Corp. recommends that rope pull switches be applied according to the guidelines set forth in the
standards listed below. In addition, the user is responsible for ensuring all local, state, and national laws, rules, codes, and
regulations relating to the use of Banner rope pull switches in each application are satisfied. Extreme care is urged that all
legal requirements are met and that all installation and maintenance instructions are followed.

Overview

The model RP-QM90F-100L is a two-sided rope pull switch in a heavy-duty metal housing. When used with steel wire rope,
it can provide stop actuation along conveyors and similar machinery. This model is designed to be mounted in the center
of a long, straight run of cable (up to 100 meters/330 ft total); this model switch does not accommodate corners along the
cable’s length. Red PVC-covered 4 mm diameter wire rope is recommended.

The switch features redundant terminal pairs. Both pairs of terminals 11–12 will act concurrently and identically to latch
open when the rope is pulled, regardless of which side of the switch the rope is pulled. Both pairs of terminals 23–24 are
normally open monitoring contacts; they will act concurrently and identically to close when the rope is pulled. If the rope
should break or become slack for any reason, the switch actuator will pull to the taut side, so contact behavior for a rope
break condition is the same as that for a rope pull. The contact pairs (the two 11–12 and the two 23–24) should be wired
together, in series.

These rope pull switches are not safeguarding devices, in that they do not protect personnel from injury. They provide the
same function as other types of stop switches.

This rope pull switch features “latching” operation. When the rope is pulled, the switch contacts 11–12 open and remain
open until the built-in reset actuator (the ring) is manually pulled to reset.

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.

Mechanical Installation

Installation Guidelines

• 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

• Mounting points, including support points, must be rigid and allow sufficient space around the rope to allow easy
access

• The rope should be free of friction at all supports. Pulleys are recommended

• The rope may not be routed around a corner, for this model.

• Never run rope through conduit or other tubing

• Never attach weights to the rope

• Temperature affects rope tension. The wire 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
Engineering or visit www.bannerengineering.com for model selection
