Level Time: To calculate Level time, add the time for one com-
plete 360° revolution (60 sec divided by the RPM), add time for
Travel Start delay and tie-in. Divide the sum by the number of
levels to get the time per level.
Time for 360 ° = 60 sec. ÷ RPM
Total Time = Time for 360° + Travel Start Delay + Tie-In
Time per Level = Total Time ÷ Number of Levels
Example: If RPM = 3.18, 60 sec. ÷ RPM = 60 sec ÷ 3.18 RPM = 18.9 sec.
Total Time = 18.9 sec. + 1.5 sec. delay + 1.5 sec. tie-in = 22 sec.
Time per level = 22 ÷ 4 = 5.5 sec per level.
If Level Position is changed, the Level Time will be automatically
recalculted. If Level Time is changed, the Level Position will be
automatically recalculated.
