Rope Pull Switches

Important... Read This First

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.

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

Models RP-QM..72-..L are rope pull switches in heavy-duty metal housings. When used with steel wire rope, they can
provide stop actuation along conveyors and similar machinery. Red PVC-covered 3 mm diameter wire rope is
recommended (see Accessories).

Some models have redundant terminal pairs (see model listing). In such models, terminals 33/34 will follow the action of
terminals 13/14 and terminals 45/46 will follow the action of terminals 25/26. Either or both contacts 33/34 and/or 45/46
may be used as monitoring contacts. Contact pairs 33/34 also may be jumpered to pairs 45/46 (in the same way that
13/14 is jumpered to 25/26) to provide dual-channel input to a safety device. When the rope is properly tensioned (using
a turnbuckle), both contacts of the switch are closed. A groove on the actuator aligns with the end of the housing flange
when tension is set for operation. When the rope is pulled, the positive-break contact between terminals 25 and 26 (and
terminals 45 and 46, for model RP-QMT72E-12L) latches open. If the rope breaks or goes slack, the contact between
terminals 13 and 14 (and terminals 33 and 34, for models RP-QMT72E-12L and RP-QMT72F-12L) opens. These contacts
typically should be wired together, in series.

Rope Pull Switches

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.

All five models feature “latching” operation. When the rope is pulled,
the switch contacts 25/26 (and 45/46, depending on model) open
and remain open until the built-in reset button is manually pulled to
reset.

Figure 1. Features

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

• 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
Engineering or visit www.bannerengineering.com for model selection

Installation Procedure

1. Mount the switch securely on a solid, stationary surface.

2. Fasten an eye bolt at the opposite end of the rope span, up to 6 m (20 ft), or 12 m (40 ft) or 20 m (66 ft) from the
switch, depending on model. The anchor for the eye bolt also must be solid and stationary, to withstand the
constant tension of the rope.

3. Assemble the rope, as shown. Keep the rope’s PVC cover intact along its complete length.

4. Use pulleys (recommended) or eye bolts at each support point. A pulley must be used when routing the rope
around a corner, regardless of the angle.

5. Apply tension to the rope using the turnbuckle until the indicator mark on the switch aligns with the leading edge of
the housing flange. This indicates sufficient rope tension. (Contacts 25/26, and 45/46, if applicable, will close.)

6. Pull hard on the rope and reset the latch several times. If contact 25/26 (45/46) remains open following the reset,
further tighten the turnbuckle, until contact 25/26 (45/46) closes.

7. Repeat step 6 until contact 25/26 (45/46) remains closed for the Run condition.

All hardware is supplied by the user. The switch mounting holes are on a mounting pattern of 72 x 40 or 72 x 76
millimeters, and accept M5 (#10) hardware. Wire rope and associated hardware may be ordered separately; see

Accessories.

Electrical Installation

Access to the Wiring Chamber. The wiring chamber is

accessed via a cover plate (remove four screws). A conduit
adapter is supplied to convert the 20 millimeter threaded
entrance to 1/2-inch NPT. An accessory cable gland that fits the
M20 thread is also available (see Accessories).

Wiring. Install a jumper wire to place switch contacts 13/14
and 25/26 in series, as shown.

For model RP-QMT72F-12L, install a jumper wire to place
contacts 33/34 and 45/46 in series, to provide a dual-channel
output to a safety device. If dual-channel output is not required,
either or both contacts may instead be used as monitoring
outputs (in which case no jumper is required).

Figure 6. Wire the two switch contacts in series

Maintenance/Checkout

At switch installation or replacement and at machine set up, a Designated Person
machine shutdown response and check the switch(es) and installation for proper operation, physical damage, mounting
(looseness), and excessive environmental contamination. This must also take place on a periodic schedule determined by
the user, based on the severity of the operating environment and the frequency of switch actuations. Adjust, repair, or
replace components as needed. If inspection reveals contamination on the switch, thoroughly clean the switch and
eliminate the cause of the contamination. Replace the switch and/or appropriate components when any parts or
assemblies are damaged, broken, deformed, or badly worn; or if the electrical/mechanical specifications (for the
environment and operating conditions) have been exceeded. Always test the control system for proper functioning under
machine control conditions after performing maintenance, replacing the switch, or replacing any component of the switch.

Additional items that should be included in the checkout and/or regularly scheduled maintenance of a rope pull system:

• Check for proper rope tension and adjust as needed

• Verify free operation (no binding) of the rope and proper tripping when the rope is pulled

• Periodically lubricate the pulleys and other moving parts associated with the rope

• Repair any loose or damaged hardware, worn/frayed rope (cable), missing red rope sheathing or flags/markers (if
used)

• Remove or clean off any contamination and eliminate its cause

Repairs
