APPLICATION

Kiepe pull-rope emergency stop switches type LRS are used in accordance with the requirements of EN 620 as well as BGI 710 and in conformity with DIN EN ISO 13850 as emergency stop devices as supplementary safety measures on conveyor belt systems. The pull rope is tensioned on one side of the actuating shaft.

The devices are suitable for indoor use and applications where the ambient temperature varies only in small range.

With the pull-rope system functionally aligned, the emergency stop signal can be triggered over a distance of 20 m.

FUNCTION

The emergency stop signal can be activated by pulling or breaking of the pull wire or by pushing the red emergency stop button when the switch is correctly adjusted. An indicator E helps to find the correct operating position P for a proper work. The contacts are actuated by a spring supported cam disc (snap action function) at the same time.

The emergency stop signal is performed with positive-making normally closed (NC) contacts in accordance with the closed circuit principle.

After the emergency stop function is triggered, the switching mechanism is locked in the shut-off position “0”. The blue reset knob can only be moved to switching position “1”, when the actuating shaft is back in operating position.

Kiepe pull-rope emergency stop switch types LRS comply with Machinery Directive 2006/42/EC. The device must only be used in electrical control circuits.

The LRS aluminum housing offers space for one (1) switching element with different contact configurations for each variant of LRS. Taking into consideration the safety data and maintenance recommendations, the pull-rope emergency stop switch type LRS can be used in safety circuits in accordance with DIN EN ISO 13849 up to Performance Level e (PLe).

In position “1”, the switching contacts are recativated and the conveyor belt is prepared for start up the belt conveyor.

Note: Resetting the pull-rope emergency stop switch must not cause the conveyor system to start up.
