Banner QMT72 Rope Pull Switches - Manual (Page 3)

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.
