........................................................................................................................ AUTOMATIC PERIODIC RECORDATION
An example of the automatic periodic recordation, under various conditions, is shown in Figure Fl. Referring to the portions
of Figure Fl marked A, B, C, D and E:
At 11:45 the computer printed a complete record including a line of average production data and a line for
each of the available options, MOISTURE, RATE, TOTALS, BLEND, and Number of ERRors.
Before 12:15 the user selectable option to print TOTALS had been turned off by the operator so that the
record at 12:15 is a complete record except for the TOTALS information.
Before 12:45 the user selectable options to print MOISTURE, RATE, TOTALS, BLEND and Number of
ERRors have all been turned off so that the record at 13:15 is single line showing the basic production
data. When no options are selected a typical workday, printed at 15 minute intervals, will fit on a single
sheet of paper.
A standard data printout will be made every time the A/C valve switches from the RUN to the Divert
position. This record marks by time and date the end of a production interval.
A Process On record will be printed every time the A/C valve switches from the Divert to the RUN position.
This record marks by time and date the start of a production interval.
The basic production data printout appears as the first line in printout A, B and D, and as the only line in C. Included in this
line of data is information about that mix being made at the point of asphalt injection. The record shows the mix number,
average mix rate in TPH, average mix temperature, and the average percent of oil in the mix. In brackets is shown data
pertaining to the A/C, i.e. average A/C temperature, A/C density, and percent A/C reclaimed from the RAP material. Also
shown is the current date and time.
The values printed for mix rate, mix temperature, percent of oil and the A/C temperature are the averaqe
values measured over the entire previous print interval.
Data optionally printed as in A, B, and D is arranged in a row and column format. Each row corresponds to one of the
selected options. Each column corresponds to one of the devices from which measurements are taken. The data values
printed are the current values at the instant the record is made.
There are substantial time delays in the process. The instantaneous values may not relate to each other
as expected except as the process is and has been stable.
The Number of ERRors, if printed, represents the number of seconds in the last print interval during which the devices
exceeded the alarm tolerance specified in the Alarm Limit Calibration sheet. No errors will accumulate if the alarm is
