PAS 001 Pull Rope Emergency Stop Switch

APPLICATION

Kiepe pull-rope emergency stop switches type PAS are used in accordance with the requirements of EN 620 as well as BGI 710 and in confirmity 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 primarily for indoor use and applications where the ambient temperature varies only in a small range. With the pull-rope-system functionally aligned, the emergency stop signal can be triggered over a distance of 30 m.

FUNCTION

The emergency stop signal can be activated by pulling or breaking of the pull wire or by pushing the blue emergency stop button when the switch is correctly adjusted. The spacer tool* helps to find the correct operating position for a proper work and has to be removed after adjustment.

The microswitches are actuated by a spring supported cam disc 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 button can only be removed to positon “1“, when the actuating shaft is back in operating position.

In position “1“, the switching contacts are reactivated and the conveyor belt is prepared for start up the belt conveyor but shall not cause the start up.
