Coiling
- Right (usually)
- Left (must be notified in words)
States
- Free: the spring is not loaded (index 0)
- Preloaded: smallest working load is applied to the spring (index 1)
- Fully loaded: maximum working load is applied to the spring (index 8)
- Limit: the spring is depressed up to coil touching (index 9)
