The kit includes two end stop clips. The end stops should be attached to the rope in a sufficient distance from each attachment point. The recommended distance can be found in the table below. This will help to avoid that Wiral LITE crashes into the attachment point if you're coming in too hot. The end stop will either derail or stop the unit before it reaches the attachment point. The lockpin will ensure that Wiral LITE stays on the line even if it derails. This is a safety measure only and we do not recommend that you use it to stop intentionally, more on recommended braking distance below. 
MOUNT END STOPS IN SAFE DISTANCE TO ATTACHMENT POINT
The end stop clip should be mounted in a safe distance to the attachment point. The distance depends on the weight of the camera you use and the incline of the line. Below is a table that shows recommended distance for different setups. See more on maximum incline for your setup.
| 0 - 500 g (0 - 1.1 lb) |
500 - 1000 g (1.1 - 2.2 lb) |
1000 - 1500 g (2.2 - 3.3 lb) |
|
| Horizontal | 3 m / 10 ft | 4 m / 13 ft | 5 m / 16.5 ft |
| Max. Incline | 1.5 m / 5 ft | 1.5 m / 5 ft | 1.5 m / 5 ft |
| Max. Decline | 5 m / 16.5 ft | 7 m / 23 ft | 9 m / 29.5 ft |
*The values are estimates, and may vary with environmental conditions.
START REDUCING THE SPEED IN A SAFE DISTANCE TO THE END STOP
The braking distance of Wiral LITE depends on the weight of the camera that you use. Below is a table that shows estimates of how much braking distance Wiral LITE will need in top speed with different payloads and incline.
| 0 - 500 g (0 - 1.1 lb) |
500 - 1000 g (1.1 - 2.2 lb) |
1000 - 1500 g (2.2 - 3.3 lb) |
|
| Horizontal | 4 m / 13 ft | 5.5 m / 18 ft | 7 m / 23 ft |
| Max. Incline | 2 m / 6.5 ft | 2 m / 6.5 ft | 2 m / 6.5 ft |
| Max. Decline | 5 m / 16.5 ft | 7 m / 23 ft | 9 m / 29.5 ft |
*The values are estimates, and may vary with environmental conditions.
COLLISION DETECTION
If the Wiral LITE is crashing into and stopped by obstacles, continuing to run the motor can burn and damage the rope. To prevent any damage, collision detection is implemented.
When sensing a collision, the Main Unit will stop for 5 second before it is allowed to continue.
