| -5- Contd. If the speed limits are not complied with, it will be generally found that the only alteration required is that of the set of the spring in the undeflected position of the weights. This set may require slightly weakening if the speed for 3° advance lies above the maximum limit. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
