- Non-Tension Cable System: The device uses an electrical communication cable. Tripping or activating the safety system occurs when this cable is subjected to specific conditions.
- Tripping Conditions: Tripping, or the activation of the emergency stop function, can occur under several conditions:
When the electrical communication cable is removed: If someone disengages or removes the cable from the internals of the device, it triggers an emergency stop.
When the electrical communication cable is pulled: If the cable is subjected to an emergency stop activation by personnel, it activates the positive drive safety mechanism which initiates an emergency stop function.
Manual Tripping: The device can also be manually tripped using a reset dial. This is a useful feature for testing and maintenance purposes or for manually stopping the system in emergency situations.
- Micro Switches: The Safe-T-Pull device is equipped with 2 or 4 direct opening safety micro switches. These safety micro switches are Single Pole Double Throw (S.P.D.T.) change-over switches. They provide a direct opening positive break in electrical signal when the conditions for activation are met.
In summary, the Safe-T-Pull device is a safety mechanism designed to stop a machine or conveyor system when certain conditions, such as cable removal, cable activation or manual dial activation, are met. The inclusion of direct opening safety micro switches coupled to a direct opening mechanical action and a reset dial allows for both automated and manual control over the emergency stop function, enhancing safety in industrial or conveyor system applications.
