Banner RP-LM40 Rope Pull Switches - Manual (Page 2)

NOTE: This symbol for a positive-opening safety contact (IEC 60947-5-1) is used in the switching
diagram to identify the point in actuator travel where the normally-closed safety contact is fully open.

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-LM40D-6 and RP-LM40D-6L are rope pull switches in compact, limit switch-style housings. When used with steel
wire rope, they can provide machine stop actuation along conveyors and similar machinery. Red PVC-covered 2 mm
diameter wire rope, up to 6 m (20 ft) long is recommended.
When the rope is properly tensioned (using a turnbuckle), both contacts of the switch are closed. When the rope is pulled,
the positive-break contacts between terminals 25–26 open. If the rope breaks or goes slack, the contacts between
terminals 13–14 open. These two contacts typically should be wired together, in series.
These rope pull switches are not safeguarding devices; they do not protect personnel from injury. They provide the same
function as other types of stop switches.
The two switch models differ in their switching operation. Model RP-LM40D-6 is a momentary switch, which returns
immediately to the Run condition (i.e., both contacts close) after releasing the rope, following a Pull condition. When using
this model, a separate latching circuit is required. Model RP-LM40D-6L latches contacts 25–26 open with each Pull
condition, and must be reset by pulling the integral reset button.
