4.6 Clock Read and Delay Start
Clock Read
CLOCK READ can be used any time the CHEF Mapper system is on, even during a run.
Pressing CLOCK READ displays the current time as hours:minutes:seconds and the current
date as month/day/year. The hours are in 24-hour time, for example, 3:00 pm is shown as
15:00:00. The time and date will appear for 5 seconds each time the key is pressed.
To set the clock or date, press CLOCK READ and DELAY START simultaneously.
The display will be: Current time: hh:mm:ss
Enter new hours [ ]
After you enter the hour, the cursor will move to minutes, then seconds. Pressing ENTER
at any of these prompts without entering a new value retains the original value. Next, the cur-
sor moves to month, day, and year.
Delay Start
DELAY START allows the system to be started at a preset time. To use delay start, enter
the run parameters of your program, then press DELAY START, which will prompt you to
enter the start time date. Enter the day, and press ENTER. For the same day, just press Enter.
After the date has been entered, the prompt will be for the hour in 24 hour time and then min-
utes. Enter the hour and minutes.
Note: Delay Start can be activated for up to 2 days, 23 hours, and 59 minutes from the cur-
rent time. If you enter a date that is more than 3 days in the future, the message Start
time more than 3 days away, Abort? will appear. Enter 0 for no to exit the Delay Start
mode. Enter 1 for yes to re-enter the delay parameters.
To activate Delay Start, press START RUN. The screen will display the message
A program is in memory. Please enter another command. At this point the delay start
instruction is in memory along with the run parameters of your program.
After delay start has been activated, the screen will indicate the current time and the
start time. Current Time: hh:mm:ss month/day/year
Start Time: hh:mm day
To exit the delay start mode after it has been activated, press ENTER. The message
