Are we still having intervals lagging? You time the intervals as you would in the minimum interval menu.
But in this case....
First make sure coordination is in Auto mode.
Then Coord Data>> Dial Split Data
Select Dial 1 Split 1 Level 2 (Interval Data) and open up the Interval Timing menu by pressing E
The intervals run down the first column, you time the ones you will use just like you have in the Minimum timing menu.
Put a "1" into the A column for Active Intervals. If you are using the first 10 intervals, and nothing else, then you put 1's into the first 10 columns.
Put a "1" into the S column for Start Up. This typically is the first interval.
You should not have to worry about columns I and O until you create a flashing program for overnight/off hours type modes.
Here is an example of interval timing for the old Michigan standard intersection using the following

That should program the interval times, but I forgot if the EPIC required additional time base programming to activate these times. First try the above steps then if you still get a delay we will try the other programming.
