Watlow Electric Ramping and Profiling Microprocessor-Based Control SERIES 1500 - Manual (Page 21)

Programming Steps 3 through 6
Now that you see how it’s done, enter the data for Set Point Steps #3,4,5, & 6. But,
be sure to stop and then return to these instructions when the display reaches “07
SP.” This is because you will be looping through Steps #4 through #6 three times.
Refer to the table below for Steps #3,4,5 and 6.

Programming Step 7, a Jump Loop Step
You now have Steps #1-6 programmed. When you run the program, Step #7 will be
performed when Step #6 is completed. But, you do not want Step #7 to be a normal
“Set Point Step.” We want Step # 7 to cause the 1500 to JUMP
back to Step #4 two
times (for a total of 3 times through Steps #4-6). That’s why you’ll program Step #7 as
a"JUMP LOOP Step.”
1. With the STEP and FUNCTION displays now reading “07 SP,” press the
FCTN key until “07 JL” comes up.
2.
3.
Press the ENTER key. The display changes to “JS” (Jump to Step #).
Enter the number of the step the program will jump to (“0004”). Press
ENTER. The display changes to “JC” (Jump Count).
4. Since you want to jump back to Step #4 two times (total of 3 times through
the loop), enter “0002.” Press ENTER. The display changes to “07 NX 0008.”
5. Press ENTER (you do want to program Step now). The diiplay
changes to “08 SP.”
Programming Step 8
You’re ready to enter Step #8. It’s a normal Set Point Step, enter the information
below (Stop with the display reading “08 NX 0009”):
S1 110.0
S2 065.0
El 1100
E2
0101
HR 0000
MN 0006
SC 0000
Recall that you set the Recycle (RC) option to ON, so the program will repeat
indefinitely. You have now entered the entire program. You’re almost ready to run it.
