CPS Series Cable Pull Safety Switch FEATURES Direct opening action of NC (normally closed) contacts 2CPS: 2NO/2NC, 1NO/3NC or 4NC contact configurations 1CPS: 1NO/1NC, 2NO/2NC, 1NO/3NC or 4NC contact configurations Typical cable span of 76 m (250 ft) in an environment with a temperature change BG (Applied for) of 17 C (30 F). Longer spans are possible depending upon temperature change and installation (ref. note on page 6 for more details or Application note - Effect of Temperature on Cable Pull Switch Operation) Choice of three actuator configurations CPS Series Cable Pull Safety Switches provide a readily accessible emergency stop (2CPS) signal. This is a cost-effective means compared to using multiple emergency stop Removable contact block version push-buttons. (Cable Pull Safety Switches are not, however, to be used as a means available (2CPS) of personnel safeguarding. They may be used to prevent further injury or damage to Large wiring cavity with straight- equipment when used for emergency stop signaling.) through wiring The CPS Series Cable Pull Safety switch is designed to provide emergency stop 24 Vdc or 120 Vac bright, multicluster protection for exposed conveyor and assembly lines. The internal mechanism LED status indicator light available on latches on both slackened cable (push) and pulled cable. This capability also en- 2CPS. Single high intensity LED on 1CPS hances productivity by eliminating nuisance stops due to variations in temperature, Gold-plated contacts are standard on stretch of cable over time, and other application variables. 2CPS, available on 1CPS The 1CPS is intended for use in applications where the cable span is 76 m (250 ft) Die-cast zinc housing or shorter. It is an economical solution for shorter runs or zone protection typical to Optional hardware packs available automated systems. The 2CPS series is intended for use in very long cable runs of 152 m (500 ft) or shorter, such as long conveyor lines found in warehouses. A line in the midpoint of the cable tension window indicates proper cable tension, TYPICAL APPLICATIONS providing easy set-up. The direct opening switch contacts are held closed when the Long conveyor systems found in actuating cable is under proper tension and the reset knob is set to RUN. When the warehouses and distribution centers actuating cable is pulled, slackened or broken, a cam positively opens the NC (Nor- Conveyor systems having a high amount mally Closed) switch contacts. The snap action, trip operation causes the switch of vibration contacts to change state and mechanically latch almost simultaneously when the Conveyor systems that experience wide cable is pulled, slackened or broken. The NC switch contacts remain open until the temperature swings CPS is reset by properly tensioning the cable and manually rotating the reset knob. Long conveyor systems where easy When the direct opening switch contacts open, the auxiliary contacts also actuate through wiring, or highly visible trip (open contacts close and closed contacts open). The auxiliary contacts are electri- status is required cally isolated from the direct opening switch contacts. These NO (Normally Open) Hose down conditions contacts may be used for monitoring or signaling.
