Article Number: 91.043 450.xxx

  • Installation: Double-side
  • Alu housing

     

Features

Kiepe pull-rope emergency stop switches type HEN 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 symmetrically tensioned on both sides of the red release lever.
The devices are suitable for outdoor use and applications where the ambient temperature varies considerably.
With the pull-rope system functionally aligned, the emergency stop signal can be triggered over a distance of up to 2 x 125 m for each switch.
Kiepe pull-rope emergency stop switch types HEN comply with Machinery Directive 2006/42/EC and UKCA conformity is available.
They must only be used in control electrical circuits.
The HEN aluminium housing offers space for up to 3 simultaneously switching NO and NC contacts. Taking into consideration the safety data and maintenance recommendations, the pullrope emergency stop switch type HEN can be used in safety circuits in accordance with DIN EN ISO 13849 up to Performance Level d (PLd).

The pull-rope emergency stop switch is actuated by a pull rope [1] connected on both sides of the red release lever. The contacts are actuated by a spring supported cam disc (snap action function). At the same time, up to three NC and NO contacts are actuated simultaneously and a cross comparison of the contacts can be performed with an external control unit. 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". When the blue reset lever is actuated in switch position "1", the switching contacts are reactivated and the conveyor belt is prepared for being turned back on again.
 

Note 

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

Reliability and Safety Data

Pull-rope emergency stop switches of types HEN are each fastened to the substructure in installation position with 2 M8 screws, centered between the anchor hook [3] of the pull-rope system (see the mounting diagram).
Electrical connection is performed with the device open using the screwed cable gland included in the delivery, directly on the screw joints of the switching elements. The pull-rope [1] is tensioned by tension springs [2] between the anchor hooks [3] and fastened at the red release lever. After the tension springs [2] have been adjusted, the actuation force and path for triggering the switch must be tested to ensure compliance with specified requirements.
 

Note:
The tension springs are designed for cable systems with Kiepe
devices at recommended temperature changes in a straight
installation. Deviations from this may require a different spring
design or an adjusted tension of the spring for wire break
detection.
