Manufacturer : EUCHNER
Description : Description Rope pull switches RPS are emergency stop devices for protecting large, expansive machine or installation areas that cannot be protected by an enclosing housing or cover. Areas of an installation or machine can be shut down immediately from any point in the working area in the event of danger. EMERGENCY STOP device with detent mechanism according to EN ISO 418 and EN 60204-1 Fast and simple rope fastening to the switch by means of tensioning device Combined EMERGENCY STOP and reset function directly on the switch housing Indication of correct rope tension 3 cable entries M20 x 1.5 Switching elements with 4 switching contacts More information Task of rope pull switches The trip range is much larger than for switches with an EMERGENCY STOP pushbutton, since operation is possible over the whole rope length and is not restricted to the small area within reach of the switch. Rope pull switches are used whenever it is necessary to protect large danger areas where it is not possible or too complex to fit a housing or cover. The advantage is that areas of an installation or machine can be shut down immediately from any point in the working area in the event of danger in cases where it would otherwise be necessary to install individual latched EMERGENCY STOP buttons at short distances apart. Function and technology used in rope pull switches The standard EN 60947-5-5 Ð 6 (requirements for EMERGENCY STOP pushbuttons and rope pull switches) specifies certain requirements that must be met by rope pull switches and that therefore also define the mode of operation of such switches. As such, the latching device (EMERGENCY STOP switch) must be reset by turning a key, by turning the pushbutton in the stated direction or by pulling. Rope pull switches are normally tripped by pulling a plastic-sheathed steel rope (known as the safety rope or pull rope). In addition, EUCHNER rope pull switches feature a latched EMERGENCY STOP button on the housing that has the same effect.
